Technical Field
The present disclosure relates to an intent indication system and a method performed in the system for indicating an ongoing or impending autonomous kinematic action of a vehicle to a potential observer, such as a vehicle occupant.
Background
Advances in autonomous vehicles have enabled computers or other electronic devices to drive the vehicle. Today there are at least two types of autonomous vehicles — semi-autonomous vehicles capable of operating in an autonomous mode with partial support of a human driver, and fully autonomous vehicles that do not require human driver interaction. Today's autonomous vehicles provide little, if any, notification of the intent of the autonomous vehicle in a discernable form to an observer, such as a vehicle occupant (e.g., a passenger). The signaling methods built into vehicles today provide the ability to communicate only a small subset of the information. This makes it challenging for vehicle occupants inside such an autonomous vehicle to plan their behavior or react to the behavior of the autonomous vehicle. As the number of autonomous vehicles increases, the need for improved communication methods between the autonomous vehicles and the vehicle occupants also increases.
For example, US20150336502a1 discloses a way of communicating between an autonomous vehicle and a person, and describes how a human-understandable output, which is explicitly or implicitly indicative of the intended course of action of the vehicle, can be transmitted via a vehicle output device. However, although US20150336502a1 provides a solution that allows an autonomous vehicle to provide a comprehensive means for signaling an external observer, there remains a need for alternative and/or improved communication methods between the autonomous vehicle and vehicle occupants.
Disclosure of Invention
It is therefore an object of embodiments herein to provide a way for indicating ongoing or impending autonomous kinematic actions of a vehicle to a potential observer, such as a vehicle occupant, in an improved and/or alternative manner.
According to a first aspect of various embodiments herein, the object is achieved by a method performed by an intent indication system of a vehicle for indicating an ongoing or impending autonomous kinematic action of the vehicle to its potential vehicle occupant. The intent indication system determines ongoing or impending autonomous kinematic action of the vehicle. The intention indicating system further provides a visible light output representing the autonomous kinematic action visible at least from the inside of the vehicle, supported from a light providing device comprising one or more light sources adapted to emit light, the light providing device being arranged continuously and/or intermittently along a substantial part of the horizontal perimeter of the vehicle.
Thereby, a way is provided according to which such vehicle occupants inside the vehicle can plan their behaviour or react to the behaviour of the vehicle. That is, as an ongoing or impending autonomous kinematic action of the vehicle is determined, a current or impending autonomous intent of the vehicle is established to be present. Furthermore, that is to say, since the visible light output representing the autonomous kinematic action, which is at least visible from the inside of the vehicle, is provided in support from a light providing device comprising one or more light sources adapted to emit light (which light providing device is arranged continuously and/or intermittently along a substantial part of the horizontal periphery of the vehicle), a light emission indicative of the autonomous kinematic action is emitted in support from distributing the one or more light sources along the vehicle and is visible within the vehicle. Thus, where the light providing device extends along at least a substantial portion of the perimeter of the vehicle, the light providing device may be viewable from substantially all horizontal angles, i.e., the light providing device may be viewable to an observer, such as a vehicle occupant from substantially anywhere inside the vehicle. Thus, the light output associated with the autonomous kinematic action may be more readily noticed by vehicle occupants, wherever they are located within the vehicle, which is a significant advantage over the prior art. Furthermore, where the light providing means comprises one or more light sources (e.g. a plurality of light sources) and extends along at least a substantial part of the perimeter of the vehicle, a greater variety of light output combinations representing different autonomous kinematic actions may be supported. That is, different autonomous kinematic actions may be represented by different types of light outputs, with each respective light output adapted to signal the type of autonomous kinematic action that it represents in an intuitive and/or human understandable manner. Thus, with the inventive concept, an ongoing or imminent autonomous kinematic action may be communicated to an observer, such as e.g. a vehicle occupant, in an improved and intuitive manner, i.e. the observer may perceive, deduce and/or judge the ongoing or imminent autonomous kinematic action and/or its type in an improved and intuitive manner.
To this end, a way is provided to indicate an ongoing or impending autonomous kinematic action of the vehicle to a potential observer, such as a vehicle occupant, in an improved and/or alternative manner.
The technical features and corresponding advantages of the above-described method will be discussed in further detail below.
By introducing a method performed by an intention indicating system of a vehicle for indicating an ongoing or imminent autonomous kinematic action of the vehicle to its potential vehicle occupants, a way is provided according to which such vehicle occupants inside the vehicle can plan their behavior or react to the behavior of the vehicle. "vehicle" may refer to an "autonomous vehicle" or a "fully autonomous or semi-autonomous vehicle," and the vehicle may support at least semi-autonomous driving as is known in the art. For example, the vehicle may be equipped with various sensors, such as cameras, radar and/or lidar, etc., that collect data about the vehicle surroundings. Based on this data and the assigned task(s), the vehicle can plan the course of action to be expected as is well known. A vehicle may also refer to any arbitrary vehicle intended for a public transportation network, e.g. an engine-propelled or electric vehicle, such as a car, truck, van, bus or rail vehicle (such as e.g. a train or tram). The expression "for indicating" may mean "for indicating in an intuitive or human-understandable manner or form", and "indicating" may mean "transmitting, communicating and/or emitting a signal". "vehicle occupant" may refer to "non-driving vehicle occupants" and/or "passengers". Further, "potential vehicle occupant" may refer to only "vehicle occupant", and "indicating to a potential vehicle occupant" may refer to indicating to at least a potential vehicle occupant ". "its" vehicle occupant may refer to a "vehicle occupant of the vehicle. A "kinematic" action may refer to a "driving-related, driving behavior, and/or motion-related" action, while an "action" may refer to a "vehicle motion, vehicle intent, and/or vehicle task. "ongoing" may refer to "current" and "imminent" may refer to "upcoming, and/or imminent".
Since the intent indication system determines ongoing or impending autonomous kinematic action of the vehicle, it establishes that there is a current or impending autonomous intent of the vehicle. Determining ongoing or impending autonomous kinematic actions may be accomplished as is known in the art, for example, by deriving data from the vehicle that maintains such information, e.g., retrievable from one or more electronic control modules. "determining" an autonomic kinematic action may refer to "deriving and/or retrieving information about the autonomic kinematic action.
Since the intention indicating system provides a visible light output representing the autonomous kinematic action that is at least visible from the inside of the vehicle, supported from a light providing arrangement comprising one or more light sources adapted to emit light, which light providing arrangement is arranged continuously and/or intermittently along a substantial part of the horizontal circumference of the vehicle, a light emission indicating the autonomous kinematic action is emitted in support from distributing the one or more light sources along the vehicle and is visible within the vehicle. Thus, where the light providing means extends along at least a substantial part of the periphery of the vehicle, the light providing means may be viewable from substantially all horizontal angles, i.e. the light providing means may be viewable to an observer of the vehicle, e.g. from substantially anywhere inside the vehicle. Thus, the light output associated with the autonomous kinematic action may be more readily noticed by the vehicle occupants, wherever located within the vehicle, which is a clear advantage over the prior art. Furthermore, where the light providing means comprises one or more light sources (e.g. a plurality of light sources) and extends along at least a substantial part of the perimeter of the vehicle, a greater variety of light output combinations representing different autonomous kinematic actions may be supported. That is, different autonomous kinematic actions may be represented by different types of light outputs, with each respective light output adapted to signal the type of autonomous kinematic action that it represents in an intuitive and/or human understandable manner. Thus, with the inventive concept, ongoing or imminent autonomous kinematic actions may be communicated to an observer, such as a vehicle occupant, in an improved and intuitive manner, and subsequently, the observer may perceive, deduce and/or judge ongoing or imminent autonomous kinematic actions and/or their types in an improved and intuitive manner.
The light providing means, which according to one example may be represented by "light strips", may have any arbitrary width (such as in a direction from the vehicle floor to the vehicle roof) considered appropriate, e.g. in terms of design combined with visibility, and may e.g. range from 2mm up to 500 mm. The width of the light providing means may further vary along the horizontal periphery of the vehicle. The light providing means may be arranged at any arbitrary height of the vehicle, such as in the direction from the vehicle floor to the vehicle roof, anywhere between floor level up to roof level, considered appropriate in view of design and visibility, for example.
The light providing means may comprise any number of light sources considered suitable, for example ranging from one up to several hundred or even thousands. The light source(s) may be distributed along the light providing means in any arbitrary manner, e.g. uniformly or non-uniformly. According to one example, the light providing means comprises at least three light sources on each side of the vehicle and at least two light sources in the front and rear, respectively. The light source may be represented by any light providing source known in the art, such as an LED, a laser, and/or a bulb, and/or an equivalent or successor thereof. The light output may involve light emission from one or more light sources of the light providing device to be considered intuitive and/or human understandable in any arbitrary combination to reflect the autonomous kinematic action it represents. Accordingly, the light output may relate to the emission of light from one or more light sources, one at a time, simultaneously, in combination, in series, etc., and may further be represented by, for example, steady light, pulsating light, light of varying brightness, intensity, and/or color, etc. The respective light emission duration of the light source may be chosen arbitrarily, for example in the range from 10ms up to several minutes or even hours. Furthermore, the light output may be repeated (e.g. continuously), e.g. at a repetition rate in the range from 0.1s up to several minutes or even hours.
"providing" a light output may refer to "initiating, communicating, signaling, and/or transmitting" the light output. On the other hand, "continuously" setting may mean "without interruption" setting, while "intermittently" setting may mean "spaced apart", e.g. spaced apart by any arbitrary distance (e.g. in the range from 0.1mm up to 5000 mm). "substantial portions" of the perimeter may refer to "more than 50% of the perimeter, while" horizontal perimeter "may refer to" substantially horizontal perimeter "and/or" perimeter in a horizontal plane or substantially horizontal plane when the vehicle is standing on a flat ground ". Thus, the substantially horizontal periphery may have a slight inclination compared to a true horizontal periphery, e.g. an inclination of at most 30 degrees compared to the horizontal when the vehicle is standing on a flat ground. The "horizontal periphery of the vehicle" may according to one example refer to the "horizontal periphery of the exterior and/or interior surfaces of the vehicle", wherein the "exterior and/or interior surfaces" may refer to only the "exterior and/or interior". The light providing means may for example be at least partially flush or substantially flush with the exterior surface and/or the interior surface of the vehicle. Visible light "output" may refer to visible light "emission" and "output" may further refer to "output combination, output session, output sequence, output string, and/or output scheme". "output" may further refer to a "burst". "visible at least from the inside of the vehicle" may mean "visible and/or viewable at least in the interior of the vehicle", while "inside" of the vehicle may mean only "inside" of the vehicle. On the other hand, "representing" an autonomic kinematic action may refer to "indicating an autonomic kinematic action," associating with an autonomic kinematic action, "" reflecting an autonomic kinematic action, "" conveying an autonomic kinematic action, "and/or" signaling an autonomic kinematic action, "and further refer to" representing a type of autonomic kinematic action. According to one example, "representing" an autonomic kinematic action may further refer to "representing" the autonomic kinematic action in an intuitive and/or human understandable manner.
Optionally, the light providing means may preferably extend along at least 60% of the horizontal perimeter, more preferably along at least 70% of the horizontal perimeter and most preferably along at least 80% of the horizontal perimeter. Thereby, the light providing means covers substantially the entire circumference of the vehicle to an even greater extent, allowing the light output associated with the autonomous kinematic action to be even more easily noticed by an observer, such as a vehicle occupant, and further allowing for supporting an even greater variety of light output combinations representing different autonomous kinematic actions.
Alternatively, the provision of the light output may be initiated a predeterminable period of time before the start of the autonomous kinematic action. Thus, the autonomous kinematic action may be initiated early (i.e., before the vehicle actually begins to perform the action). This gives the observer advance information of the actions and enables the observer to plan his or her behaviour in advance and/or to react to the behaviour of the autonomous vehicle. The time period may be arbitrarily chosen, for example depending on the type of autonomous kinematic action to be performed, and may for example range from 0.5s up to 10 s. "predeterminable time period" may refer to "predetermined time period" or only "time period", while "initiated" may refer to "initiated". Before may mean "before" and/or "before", while an autonomous kinematic action "start" may mean that the autonomous kinematic action "is performed and/or initiated".
Additionally or alternatively, optionally, the light output may be activated for a predeterminable period of time and/or until the end of the autonomous kinematic action. Thus, an autonomic kinematic action may be communicated during a selected period of time or until the action is no longer active and/or relevant. This gives the observer information about the action during a sufficient period of time and enables the observer to plan his or her behavior accordingly and/or react to the behavior of the autonomous vehicle. The time period may be arbitrarily chosen, for example depending on the type of autonomous kinematic action to be performed, and may for example range from 0.5s up to several minutes or even hours. The "predeterminable period of time" may refer to a "predetermined period of time" or simply a "period of time". The "activation" may refer to "continuation and/or emission" of a predeterminable time period, while the expression "ending" of an autonomic kinematic action may refer to the autonomic kinematic action "terminating and/or no longer being activated, continued or active". According to an example, the expression "activating a predeterminable time period and/or until" the end of the voluntary kinematic action "may mean" terminating and/or aborting after a predeterminable time period and/or when the voluntary kinematic action ends ".
Optionally, the autonomous kinematic action may include acceleration. Thus, the action may be represented by an acceleration of the vehicle. The light output may then comprise a light emission from one or more light sources of the light providing means considered to be suitable for emitting a signal of "acceleration". Additionally or alternatively, the autonomous kinematic action may optionally include deceleration. Thus, the action may be represented by a deceleration of the vehicle. The light output may then comprise the light output from one or more light sources of the light providing device considered to be suitable for emitting a "slow down" signal. According to one example, the light providing device may comprise at least a first, a second and a third light source on respective left and right sides of the vehicle, the first light source being located in front of the second light source in a forward direction of the vehicle, and the second light source being located in front of the third light source in said forward direction. Then when the autonomous kinematic action includes acceleration, then the light output may include light emission from a first light source on the left and/or right side at a first time, light emission from a second light source on the left and/or right side at a second time subsequent to the first time, and light emission from a third light source on the left and/or right side at a third time subsequent to the second time. Thus, the autonomous kinematic action of vehicle acceleration with the at least first, second and third light sources emitting light in the specified sequence, which may be perceived as a light output moving in a rearward direction of the vehicle, is communicated to an observer, such as a vehicle occupant, in an intuitive and easily viewable manner. Correspondingly, according to another example, when the autonomous kinematic action then comprises a deceleration, then the light output may comprise light emission from the third light source on the left and/or right side at a first time instant, light emission from the second light source on the left and/or right side at a second time instant subsequent to the first time instant, and light emission from the first light source on the left and/or right side at a third time instant subsequent to the second time instant. Thus, the autonomous kinematic action of vehicle deceleration with the at least first, second and third light sources emitting light in the specified sequence, which may be perceived as a light output moving in a forward direction of the vehicle, is communicated to an observer, such as a vehicle occupant, in an intuitive and easily viewable manner. The light output may be repeated continuously, for example at a repetition rate in the range from 0.1s up to 5 s. Furthermore, the respective light emission durations of the at least first, second and third light sources may be arbitrarily selected, for example in a range from 10ms up to 5s, respectively. Furthermore, the light emissions from the respective light sources may overlap at least to a certain extent, i.e. the duration of the first light emission may partially overlap with the duration of the second light emission, and correspondingly the duration of the second light emission may partially overlap with the duration of the third light emission. Additionally or alternatively, the at least first, second and third light sources may each emit light one at a time, i.e. provide non-overlapping light emissions. The type of light emission from the respective at least first, second and third light source may be arbitrarily chosen to be considered appropriate, e.g. represented by steady light, pulsating light, light of varying brightness, intensity and/or color, etc. According to an example, the first light source may be represented by a plurality of light sources, the second light source by a plurality of light sources and/or the third light source by a plurality of light sources, e.g. LEDs. The expression "on the respective left and right sides of the vehicle" may mean "on one side of the vehicle, which is the left and right side".
Additionally or alternatively, optionally, the autonomous kinematic action may include a lateral motion. Thus, the action may be represented by the vehicle changing lanes and/or turning, for example. According to an example, when the autonomous kinematic action comprises a sideways movement to the left, then the light output may comprise light emission from one or more light sources of the light providing device on the left side of the vehicle. Thus, with the light providing device emitting light on the left side of the vehicle, the autonomous kinematic action of the vehicle turning left and/or changing lanes e.g. to the left is communicated to an observer, such as a vehicle occupant, in an intuitive and easily viewable manner. Correspondingly, optionally, when the autonomous kinematic action comprises a sideways movement to the right, then the light output may comprise light emission from one or more light sources of the light providing device on the right side of the vehicle. Thus, with the light providing device emitting light on the right side of the vehicle, autonomous kinematic actions of the vehicle turning to the right and/or changing lanes e.g. to the right are communicated to an observer, such as a vehicle occupant, in an intuitive and easily viewable manner.
Additionally or alternatively, optionally, the autonomous kinematic action may include a transition from an off state to a rest state. Thus, the action may be represented by the vehicle changing mode from an off state and/or an engine off state to an idle state (such as, for example, before driving away) in which the vehicle may be on but stationary. According to an example, the light output may then comprise light emissions from one or more light sources of the light providing device considered suitable for mimicking and/or "wake up" -like behavior. For example, the light output may include light emitted in a pulsatile manner so as to mimic heartbeat and/or respiration (e.g., pulsatile at an increased rate). Alternatively, light may be emitted that looks, for example, to light output around the vehicle loitering (e.g., at an increased speed). Thus, the autonomous kinematic action of the vehicle transitioning from the off state to the stationary state is communicated to an observer, such as a vehicle occupant, in an intuitive and easily viewable manner. The "stationary" state may refer to an "idle and/or standby" state and/or an "active and/or awake but non-mobile" state.
Additionally or alternatively, optionally, the autonomous kinematic action may include a transition from a rest state to an off state. Thus, the action may be represented by the vehicle changing from an idle state where the vehicle may be on but stationary to an off state and/or an engine off state. According to one example, the light output may then comprise one or more light sources from the light providing device considered as light emission suitable for mimicking the behavior of "falling asleep". For example, the light output may comprise light emitted in a pulsed manner so as to mimic heartbeat and/or breathing, for example pulsed at a reduced rate so as to mimic and/or resemble falling asleep. Alternatively, light may be emitted that looks, for example, around the light output of the vehicle loitering (e.g., at a reduced speed). Thus, the autonomous kinematic action of the vehicle transitioning from a stationary state to an off state is communicated to an observer, such as a vehicle occupant, in an intuitive and easily viewable manner.
Additionally or alternatively, optionally, the autonomous kinematic action may include backward travel. Thus, the action may be represented by reversing the vehicle. According to one example, the light output may then comprise a light output from one or more light sources of the light providing device considered to be suitable for emitting a "reverse warning" signal. For example, the light output may include light emitted in a blinking manner so as to mimic and/or resemble a warning. Thus, the autonomous kinematic action of the vehicle traveling backwards is communicated to an observer, such as a vehicle occupant, in an intuitive and easily viewable manner.
Additionally or alternatively, optionally, the autonomous kinematic action may include a steady state motion. Thus, the action may be represented by the vehicle being in a stable and/or current driving state, and according to one example, the light output may then comprise a light output from one or more light sources of the light providing device considered suitable for signaling an "unchanged driving condition". For example, the light output may include emitting continuous soft and/or low intensity light to signal an unchanged driving condition. Thus, the autonomous kinematic actions of the vehicle in steady state motion are communicated to an observer, such as a vehicle occupant, in an intuitive and easily viewable manner. "steady state motion" may refer to "steady state forward motion".
Optionally, the intent indication system may further determine that the vehicle occupant is inside the vehicle. Thus, an autonomous kinematic action, e.g. providing a light output, is only indicated when it is determined that someone is in the vehicle. That is, an autonomous kinematic action is indicated only when someone within the possible vehicle may observe the indication. Thus, in this scenario, the autonomous kinematic action is only indicated when considered relevant, and thus unnecessary and/or excessive indications may be avoided. Detecting that the vehicle occupant is inside the vehicle may be carried out as known in the art, e.g. by means of one or more sensors or detection sensors, such as e.g. a camera, weight sensor(s), pulsation sensor(s) etc. adapted to sense the presence of a human being. In this context, "determining" may refer to "sensing" and "inboard of the vehicle" may refer to "in the vehicle". "one" vehicle occupant may refer to "at least one" vehicle occupant.
Optionally, the intent indication system may further perform vertical vehicle movements representative of autonomous kinematic actions, including raising and/or lowering a front and/or rear of a body of the vehicle. Thereby, by additionally raising and/or lowering the front and/or rear part of the body of the vehicle in a manner reflecting the autonomous kinematic actions, said autonomous kinematic actions can be signaled in an intuitive and eye-catching manner to an even greater extent and be easily noticed even further by an observer, such as a vehicle occupant, since such a vertical vehicle movement is provided in addition to the light output. That is, different autonomous kinematic actions may be represented by different types of vertical vehicle movements of the body, wherein each respective vertical vehicle movement is adapted to signal the type of autonomous kinematic action it represents in an intuitive and/or human understandable manner. For example, when the autonomous kinematic action includes a transition from a stationary state to a closed state, the vertical vehicle motion may include lowering the front and rear portions of the vehicle body, thus lowering the entire vehicle body. Additionally or alternatively, when the autonomous kinematic action includes a transition from a closed state to a stationary state, the vertical vehicle movement may include raising the front and rear of the vehicle body, thus raising the entire vehicle body. Additionally or alternatively, when the autonomous kinematic action includes acceleration, the vertical vehicle motion may include raising the front and/or lowering the rear. Additionally or alternatively, when the autonomous kinematic action includes deceleration, the vertical vehicle motion may include lowering the front and/or raising the rear. Thus, by additionally communicating an ongoing or imminent autonomous kinematic action by means of a vertical vehicle movement of the body reflecting the type of action, said action may be communicated to an observer, such as a vehicle occupant, in an improved and intuitive manner to an even greater extent, and subsequently, the observer may perceive, deduce and/or judge the ongoing or imminent autonomous kinematic action and/or its type in an improved and intuitive manner to an even greater extent. Vertical vehicle motion may refer to vertical motion relative to the ground on which the vehicle is located, e.g., motion along the normal of the ground. That is, "vertical" relates to a vehicle that is assumed to be on a flat, level ground; if the ground is inclined, the vertical direction will change accordingly. "vertical vehicle motion" may refer to "substantially vertical vehicle motion", i.e. vertical vehicle motion may differ to some extent from motion along the normal of the ground, e.g. up to 45 degrees. The degree to which the front and/or rear portion of the vehicle body is raised and/or lowered may be arbitrarily selected, for example based on the type of autonomous kinematic action represented by the vehicle platform and/or vertical vehicle motion of the build vehicle. According to one example, the front and/or rear portion of the vehicle body may be raised in a range of 5mm up to 500 mm. However, the body is preferably not raised and/or lowered to such an extent as to make it inconvenient for potential vehicle occupants or to make it possible for the vehicle to hit the ground. The "front" of the vehicle body may refer to the front section of the vehicle, up to 50% of the length of the vehicle. Correspondingly, "rear" may refer to the rear section of the vehicle, up to 50% of the length of the vehicle. Further, the front and/or rear "portions" of the body may refer to front and/or rear "sections, ends and/or portions" of the body. According to one example, "body" may refer to a "vehicle enclosure. "performing" vertical vehicle movement may refer to "transmitting and/or initiating" vertical vehicle movement. Vertical vehicle movement may be provided, for example, by means of hydraulic, magnetic and/or air suspension of the vehicle body. The execution of the vertical vehicle movement may be initiated simultaneously with, before or subsequent to the initiation of the provision of the light output. Correspondingly, the vertical vehicle movement may be performed for a shorter, equally long or longer duration than the provision of the light output.
Additionally or alternatively, optionally, the intent indication system may further provide a sound output representative of the autonomous kinematic action. Thereby, by additionally providing a sound output reflecting the autonomous kinematic action, the autonomous kinematic action may be signaled in an intuitive and eye-catching manner to an even greater extent and further be easily noticed by an observer, such as a vehicle occupant. That is, different autonomous kinematic actions may be represented by different types of sound outputs, with each respective sound output adapted to signal the type of autonomous kinematic action that it represents in an intuitive and/or human understandable manner. The sound output may have any selected frequency, volume, duration, etc., as considered appropriate to reflect the autonomous kinematic action it refers to in an intuitive and/or human understandable manner, and may further be represented by, for example, a beep, a sound signal, a jingle, etc. Thus, by additionally communicating an ongoing or imminent autonomous kinematic action by means of a sound output reflecting the type of action, the action may be communicated to an observer, such as a vehicle occupant, in an improved and intuitive manner to an even greater extent, and subsequently, the observer may perceive, deduce and/or judge the ongoing or imminent autonomous kinematic action and/or its type in an improved and intuitive manner to an even greater extent. The sound output may be provided with support from one or more loudspeakers, which may for example be distributed over different sections of the vehicle. The sound output may further be directed in different directions depending on the location where the potential observer may have been detected, and further the volume of the sound output is adapted to the distance to the potential observer and/or the surrounding sound of the vehicle. The sound output may further be directed according to the autonomous kinematic action it reflects, e.g. directing the sound backwards if the autonomous kinematic action is backward travel. The provision of the sound output may be initiated simultaneously with, before or subsequent to the initiation of the provision of the light output. Correspondingly, the provision of the sound output may last shorter, as long or longer than the provision of the light output.
Optionally, the light providing means may additionally be at least partially visible from the outside of the vehicle, for example by being at least partially transparent and/or translucent. Thus, the light output may additionally be visible from the outside of the vehicle in addition to being visible from at least the inside of the vehicle. Thus, in addition to being communicated to potential observers within the vehicle, the autonomous kinematic actions may additionally be communicated to potential external observers of the vehicle. "from the outside of the vehicle" may refer to only the "outside" of the vehicle.
According to a second aspect of embodiments herein, the object is achieved by an intention indicating system of a vehicle, the intention indicating system being adapted to indicate to a potential vehicle occupant thereof an ongoing or impending autonomous kinematic action of the vehicle. The intent indication system comprises a motion determination unit adapted to determine an ongoing or imminent autonomous kinematic motion of the vehicle. The intention-indicating system further comprises means adapted to provide a visible light output representing said autonomous kinematic action visible at least from the inside of the vehicle, supported from light providing means comprising one or more light sources adapted to emit light, the light providing means being arranged continuously and/or intermittently along a substantial part of the horizontal periphery of the vehicle.
Optionally, the light providing means may preferably extend along at least 60% of the perimeter, more preferably along at least 70% of the perimeter and most preferably along at least 80% of the perimeter.
Alternatively, the light output providing unit may be adapted to initiate the provision of the light output a predeterminable time period before the start of the autonomous kinematic action.
Additionally or alternatively, optionally, the light output providing unit may be adapted such that the light output is activated for a predeterminable period of time and/or until the autonomous kinematic action is ended.
Optionally, the autonomous kinematic action may include acceleration, deceleration, lateral motion, transition from an off state to a rest state, transition from a rest state to an off state, backward travel, and/or steady state motion.
Optionally, the intention indicating system may further comprise an observer determination unit adapted to determine that the vehicle occupant is inside the vehicle.
Optionally, the intention indicating system may further comprise a vertical movement performing unit adapted to perform vertical vehicle movements representing autonomous kinematic actions, the vertical vehicle movements comprising raising and/or lowering a front and/or a rear of a body of the vehicle. Additionally or alternatively, the intent indication system may further comprise a sound output providing unit adapted to provide a sound output representing the autonomous kinematic action.
Optionally, the light providing means may additionally be at least partially visible from the outside of the vehicle.
Advantages similar to those mentioned above in relation to the first aspect correspondingly apply to the second aspect, which is why these advantages are not discussed further.
According to a third aspect of various embodiments herein, the object is achieved by a vehicle comprising an intent indication system as discussed above. Also, similar advantages as those mentioned previously in relation to the first aspect correspondingly apply to the third aspect, which is why these advantages are not discussed further.

Alternatively, light may be emitted that, for example, appears to wander (e.g., at an increased speed) around the
Additionally or alternatively, optionally, the autonomous kinematic action may include a transition from a rest state to an off state. According to an example, the light output may then comprise light emissions from the one or more light sources 30 of the light providing device 3 considered to be suitable for mimicking a "falling asleep" behaviour. For example, the light output may comprise light emitted in a pulsed manner so as to mimic heartbeat and/or breathing, for example pulsed at a reduced rate so as to mimic and/or resemble falling asleep. Alternatively, light may be emitted that, for example, appears to wander (e.g., at a reduced speed) around the
Additionally or alternatively, optionally, the autonomous kinematic action may include backward travel. According to an example, the light output may then comprise a light emission from one or more light sources 30 of the light providing device 3 considered to be suitable for signaling a "reverse warning". For example, the light output may include light emitted in a blinking manner so as to mimic and/or resemble a warning. Thus, as shown with at least support from fig. 1, the autonomous kinematic action of the backward travel of the
Additionally or alternatively, optionally, the autonomous kinematic action may include a steady state motion. According to an example, the light output may then comprise a light emission from one or more light sources 30 of the light providing device 3 considered to be suitable for signaling an "unchanged driving environment". For example, the light output may include emitting continuous soft and/or low intensity light to signal constant driving conditions. Thus, as shown with at least support from fig. 1, the autonomous kinematic actions of the
Alternatively, the provision of the light output may be initiated a predeterminable period of time before the start of the autonomous kinematic action. Correspondingly, the light output providing unit 102 may be adapted to initiate the provision of the light output a predeterminable time period before the start of the autonomous kinematic action. Thus, as shown with at least support from fig. 1-2, the autonomous kinematic action may be communicated prior to initiation (i.e., prior to the
Optionally, the light output may be activated for a predeterminable period of time and/or until the end of the autonomous kinematic action. Correspondingly, the light output providing unit 102 may be adapted such that the light output is activated for a predeterminable period of time and/or until the end of the autonomous kinematic action. Thus, as shown with at least support from fig. 1-2, an autonomic kinematic action may be conveyed during a selected period of time or until the action is no longer active and/or relevant. This gives the observer information about the action during a sufficient period of time and enables the observer to plan his or her behaviour accordingly and/or react to the behaviour of the
Act 1003
In an optional act 1003, the intention indicating system 1 may perform a vertical vehicle movement representing an autonomous kinematic act, including raising and/or lowering the front and/or rear of the body of the
Act 1004
In an optional act 1004, the intent indication system 1 may provide a sound output representing the autonomous kinematic action, for example by means of an optional sound output providing unit 104. Thus, as shown with at least support from fig. 2, by additionally providing a sound output reflecting an autonomous kinematic action, the autonomous kinematic action may be signaled in an intuitive and compelling manner to an even greater extent and further be readily noticeable to an observer such as a vehicle occupant. The sound output may be provided, for example, with support from the speaker(s) system shown in fig. 2.
