Technical Field

The invention relates to the technical field of vehicles, in particular to a reminding method for a vehicle, a corresponding reminding device and the vehicle.

Background

In order to remind pedestrians of coming and going electric vehicles, an alarm sound speaker is generally installed on the electric vehicle. The alarm sound loudspeaker is used for reminding the coming and going people and/or animals of paying attention to the fact that the surrounding electric vehicles pass through under the condition that the vehicle runs at a low speed, and safety needs to be paid attention to. However, there are some problems with existing reminder schemes.

For example, in the existing reminding scheme, the alarm sound speaker cannot be automatically turned on and off, an alarm sound is emitted even when there are no pedestrians around, the sound source of the alarm sound is monotonous, and if there is no retreat of pedestrians and/or animals after the alarm sound is emitted, no further measures are taken, which results in low convenience in use and poor user experience.

Detailed Description

In order to make the above and other features and advantages of the present invention more apparent, the present invention is further described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are for purposes of illustration only and are not intended to be limiting.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the specific details need not be employed to practice the present invention. In other instances, well-known steps or operations are not described in detail to avoid obscuring the invention.

Fig. 1 schematically shows a flow chart 100 of a reminder method for a vehicle according to an embodiment of the invention. The method 100 may include step S101, step S102, step S103, and step S104.

In step S101, whether one or more obstacles exist within a predetermined range of the vehicle is detected, and if so, position information and distance information of the one or more obstacles are further detected. Wherein the presence or absence of one or more obstacles within a predetermined range of the vehicle (e.g. a range of 5 meters, 3 meters, 2 meters, 1 meter or other longer or shorter predetermined distances from the periphery of the vehicle) may be detected by a detection unit arranged on the vehicle.

The detection unit may include one or more sensors such as, but not limited to, lidar, ultrasonic radar, and/or millimeter wave radar. Preferably, the number and arrangement positions of the sensors are selected so that the sum of their detection ranges covers the periphery of the vehicle. The obstacles may be, for example, but not limited to, humans, animals, vehicles, and/or spacer piles, etc., and the one or more obstacles may be different types of obstacles. In the case where it is detected that an obstacle is present within a predetermined range of the vehicle, the position information and the distance information of the one or more obstacles may be further detected by a detection unit (e.g., an ultrasonic radar) arranged on the vehicle. The position information may be, for example, a coordinate position of each of the one or more obstacles in a coordinate system centered on the vehicle, and the distance information may be, for example, a shortest distance between each of the one or more obstacles and the vehicle, or a distance of the obstacle from a side of the vehicle corresponding to the obstacle.

In step S102, in response to detecting the presence of one or more obstacles within the predetermined range of the vehicle, an image about the one or more obstacles is acquired based on the detected position information and distance information of the one or more obstacles. In one embodiment, the image acquisition unit may acquire an image within a predetermined range of a vehicle through an image sensor (e.g., a camera) disposed on the vehicle. Preferably, the number and arrangement positions of the image sensors are selected such that the sum of their pickup ranges covers the periphery of the vehicle, the picked-up image may include the one or more obstacles, for example, and the picked-up image corresponding to each of the one or more obstacles is acquired based on the position information and the distance information of each of the one or more obstacles.

In step S103, the acquired images of the one or more obstacles are analyzed, and the type of the one or more obstacles is identified. Wherein the acquired image may be analyzed by means of an existing image recognition algorithm in an image analysis unit, such as a 360 camera controller of the vehicle, to identify the type of the one or more obstacles. The type of the one or more obstacles identified may be the same or different. For example, in one embodiment, there are two obstacles within a predetermined range of the vehicle, one of the two obstacles being of a type that is a person and the other of the two obstacles being of a type that is an isolation peg.

In step S104, if it is recognized that the type of at least one obstacle of the one or more obstacles is a human and/or an animal, a warning sound is output based on the traveling speed of the vehicle and information of the at least one obstacle. When at least one of the one or more obstacles is a human and/or animal in type, a warning unit on the vehicle may be used to emit a warning tone to alert the human and/or animal to notice the vehicle and avoid.

The speed of the vehicle can be detected by a sensor (e.g., a vehicle speed sensor) disposed on the vehicle to obtain the driving speed of the vehicle or by accessing an automotive Electronic Stability Controller (ESC module) of the vehicle to obtain the speed of the vehicle. The volume and the sound source of the warning alarm sound may be related to the traveling speed of the vehicle and the information of the at least one obstacle. For example, in one embodiment, the greater the travel speed of the vehicle and the closer the at least one obstacle is to the vehicle, the greater the volume of the warning sound is reminded; accordingly, the smaller the traveling speed of the vehicle and the farther the at least one obstacle is from the vehicle, the smaller the volume of the warning sound is. The sound source of the warning sound may also be different according to the traveling speed of the vehicle and the information of the at least one obstacle. Further, in a case where each of the one or more obstacles is not a human or animal in type, the operation of outputting the warning alarm sound as described above is not performed.

In one embodiment, different levels of warning sounds are set according to the traveling speed of the vehicle and the information of the at least one obstacle, and the correspondence between the sound volume and sound source of the warning sounds and the traveling speed of the vehicle and the information of the at least one obstacle is stored in a database. For example, in practical applications, the volume and the sound source of the warning sound may be set according to the traveling speed V of the vehicle a and information of one obstacle B (the type of the obstacle B is human or animal) existing within a predetermined range of the vehicle a; the volume and sound source of the warning sound correspond to the traveling speed V of the vehicle a and the information of the obstacle B, and the correspondence is stored in a database D, so that the warning unit of the vehicle a accesses the database D to acquire the volume and sound source of the corresponding warning sound, and drives the warning sound speaker to output the warning sound.

Specifically, for example, the volume and the sound source of the alarm sound may be set as described below.

When the speed V of the vehicle A is greater than 15km/h and less than or equal to 20 km/h: when the distance between the obstacle B and the vehicle a is greater than 0 m and equal to or less than 1 m, setting the volume of the warning sound to 100% of the maximum volume, and setting the sound source of the warning sound to "sound source 1 (e.g., song 1, ringtone 1, or the like)"; when the distance between the obstacle B and the vehicle a is greater than 1 meter and 2 meters or less, the volume of the warning sound is set to 75% of the maximum volume, and the sound source of the warning sound is set to "sound source 1 (e.g., song 1, ringtone 1, or the like)"; when the distance between the obstacle B and the vehicle a is greater than 2 meters and 5 meters or less, the sound volume of the warning sound is set to 50% of the maximum sound volume, and the sound source of the warning sound is set to "sound source 1 (e.g., song 1, ringtone 1, or the like)".

Similarly, when the speed V of the vehicle A is greater than 10km/h and less than or equal to 15 km/h: when the distance between the obstacle B and the vehicle a is greater than 0 m and equal to or less than 1 m, setting the volume of the warning sound to 100% of the maximum volume, and setting the sound source of the warning sound to "sound source 2 (e.g., song 2, ringtone 2, or the like)"; when the distance between the obstacle B and the vehicle a is greater than 1 meter and 2 meters or less, the volume of the warning sound is set to 75% of the maximum volume, and the sound source of the warning sound is set to "sound source 2 (e.g., song 2, ringtone 2, or the like)"; when the distance between the obstacle B and the vehicle a is greater than 2 meters and 5 meters or less, the sound volume of the warning sound is set to 50% of the maximum sound volume, and the sound source of the warning sound is set to "sound source 2 (e.g., song 2, ringtone 2, or the like)".

Similarly, when the speed V of the vehicle a is 10km/h or less: when the distance between the obstacle B and the vehicle a is greater than 0 m and 1 m or less, the volume of the warning sound is set to 100% of the maximum volume, and the sound source of the warning sound is set to "sound source 3 (e.g., song 3, ringtone 3, or the like)"; when the distance between the obstacle B and the vehicle a is greater than 1 meter and 2 meters or less, the volume of the warning sound is set to 75% of the maximum volume, and the sound source of the warning sound is set to "sound source 3 (e.g., song 3, ringtone 3, or the like)"; when the distance between the obstacle B and the vehicle a is greater than 2 meters and 5 meters or less, the sound volume of the warning sound is set to 50% of the maximum sound volume, and the sound source of the warning sound is set to "sound source 3 (e.g., song 3, ringtone 3, or the like)". The above settings are stored in the database D. It should be noted that the above-mentioned setting of the distance or the volume is only for illustrative purposes, and other settings or changes of the setting may be made according to actual circumstances.

In addition, if the type in which more than one obstacle exists within the predetermined range of the vehicle a is human or animal, it is preferable that a warning alarm sound be output according to information corresponding to the obstacle closest to the vehicle a and the setting of the traveling speed of the vehicle. For example, when the speed V of the vehicle A satisfies more than 15km/h and 20km/h or less: the distance between one obstacle and the vehicle A is greater than 0 meter and less than or equal to 1 meter, then according to the corresponding setting, the volume of the alarm sound is 100% of the maximum volume, and the sound source of the alarm sound is 'sound source 1'; if the distance between the other obstacle and the vehicle a is greater than 1 meter and 2 meters or less, the volume of the warning sound is 75% of the maximum volume, and the sound source of the warning sound is "sound source 1" according to the corresponding setting, and the warning sound is preferably output with the volume of the warning sound being 100% of the maximum volume and the sound source of the warning sound being "sound source 1".

In addition, the operation of the detection unit to detect the obstacle may be continuously performed, so that the volume and sound source of the warning sound may be dynamically adjusted according to the data detected in real time to avoid noise pollution. For example, when it is detected that the distance between the person and the vehicle is greater than 0 m and 1 m or less, the volume of the warning sound is 100% of the maximum volume, and when it is detected that the distance between the person and the vehicle is greater than 1 m and 2 m or less (for example, in the case where the person moves after hearing the warning sound), the volume of the warning sound is adjusted to 75% of the maximum volume accordingly.

In another embodiment, a new sound source may be transmitted to a warning device of the vehicle via bluetooth and stored in a warning sound memory of the warning device of the vehicle. The electronic equipment (for example, a mobile phone, a smart watch, a tablet computer or other wearable intelligent equipment and the like) of the user can be connected with the reminding device of the vehicle through Bluetooth, the user transmits a new sound source to the reminding device of the vehicle through Bluetooth and stores the new sound source in an alarm sound storage, and the user can modify the sound source of the set alarm sound stored in the database through an on-vehicle display screen and the like. The above operation is preferably performed when the vehicle is in a non-driving condition.

In yet another embodiment, a warning sound is broadcast audibly through a microphone and warning sound speaker disposed within the vehicle for alerting in the event that the warning sound is sustained for a threshold time and the at least one obstacle is not being cleared. When the warning sound lasts for a threshold period of time (e.g., 5 seconds, 2 seconds, or other longer or shorter time) and the obstacle is not to be cleared, the user may activate a microphone built in the vehicle, such as by pressing a shortcut key on the steering wheel, to audibly broadcast via the microphone and warning sound speaker to alert people and/or animals around the vehicle to the clear.

In one embodiment, detecting whether one or more obstacles are present within a predetermined range of the vehicle is performed when the vehicle is traveling at a low speed. The step of detecting an obstacle is not performed if the travel speed of the vehicle is greater than a predetermined threshold (e.g., 20km/h or other greater or lesser predetermined speed). That is, in this embodiment, the method of the present invention is applied to a case where the vehicle runs at a low speed. This is mainly because the vehicle (especially, the electric vehicle) is less likely to emit sound when running at a low speed and is not easily noticed by a person, and thus, the vehicle needs to be reminded.

In one embodiment, the scheme of the invention can be realized by using a vehicle-mounted ultrasonic radar, a vehicle-mounted camera and a vehicle-mounted video entertainment system, so that people and/or animals in a preset range of a vehicle can be automatically detected without increasing hardware cost, and a reminding alarm sound can be output according to the speed of the vehicle and information of the people and/or the animals.

Fig. 2 schematically shows a reminder device 200 for a vehicle according to an embodiment of the invention. The warning device 200 for a vehicle includes a detection unit 201, an image acquisition unit 202, an image analysis unit 203, and an alarm unit 204. The detection unit 201 is communicatively coupled with an image acquisition unit 202, the image acquisition unit 202 is communicatively coupled with an image analysis unit 203, and the image analysis unit 203 is communicatively coupled with an alarm unit 204.

The detection unit 201 may be configured to detect whether one or more obstacles are present within a predetermined range of the vehicle, and if so, further detect position information and distance information of the one or more obstacles. In one embodiment, the detection unit 201 includes one or more radars mounted on a vehicle, detects whether an obstacle exists within a predetermined range of the vehicle by detecting the one or more radars whose range covers the circumference of the vehicle, and detects position information and distance information of the obstacle using the one or more radars.

The image acquisition unit 202 may be configured to acquire an image about one or more obstacles based on the detected position information and distance information of the one or more obstacles in response to detecting the presence of the one or more obstacles within the predetermined range of the vehicle. In one embodiment, the image acquisition unit 202 may capture images of the surroundings of the vehicle through one or more cameras mounted on the vehicle, and acquire images about the one or more obstacles therein based on the position information and the distance information of the detected obstacles.

The image analysis unit 203 may be configured to analyze the acquired image about the one or more obstacles, identifying a type of the one or more obstacles. In one embodiment, both the image analysis unit 203 and the image acquisition unit 202 are comprised in a 360 picture controller of a vehicle, the image analysis unit 203 analyzing images about obstacles and identifying the type of obstacle using existing image recognition algorithms.

The warning unit 204 may be configured to output a warning sound based on the traveling speed of the vehicle and information of at least one obstacle if it is recognized that the type of the at least one obstacle is a human and/or an animal. In one embodiment, the warning unit may include an audio-visual entertainment host, and the warning sound is outputted by the audio-visual entertainment host of the vehicle, and the audio-visual entertainment host outputs an appropriate warning sound in combination with the information on the driving speed and the obstacle of the vehicle acquired from the ESC module after receiving the signal indicating the warning transmitted through the CAN network.

In one embodiment, the warning unit 204 may further include a database configured to store a correspondence between a volume and a sound source of the warning sound and the information on the traveling speed of the vehicle and the at least one obstacle, wherein different levels of the warning sound are set according to the traveling speed of the vehicle and the information on the at least one obstacle.

In one embodiment, the alarm unit 204 may also include an alarm tone memory located in the vehicle's audiovisual entertainment host that is capable of receiving a new audio source via bluetooth and storing the new audio source. For example, a user's smartphone is connected via bluetooth to receive the new audio source and store the new audio source.

The warning unit 204 may further include a microphone and a warning sound speaker disposed within the vehicle, the warning unit being configured to allow a vehicle user to audibly broadcast through the microphone and the warning sound speaker disposed within the vehicle for a reminder if a warning sound is sustained for a threshold time and the at least one obstacle is not cleared. In one embodiment, a user of the vehicle can start a microphone arranged in the vehicle by pressing a shortcut key of a steering wheel under the condition that an obstacle is not avoided, and the user can broadcast voice to remind people to avoid the obstacle to the outside of the vehicle through the microphone and a warning sound loudspeaker.

The detection unit 201 may be further configured to perform the detection of whether one or more obstacles are present within a predetermined range of the vehicle when the vehicle is traveling at a low speed. In one embodiment, the operation of detecting an obstacle may not be performed using the detection unit if the traveling speed of the vehicle is greater than a predetermined threshold (e.g., 20km/h or other greater or lesser predetermined speed).

The invention is further described below in connection with fig. 3.

Fig. 3 is a schematic view showing a reminder device for a vehicle according to another embodiment of the present invention. In fig. 3, the existing radar and camera of the vehicle are used for respectively performing detection operation and image acquisition operation, and related information is transmitted to the audio-video entertainment host of the vehicle through the CAN network so as to further realize outputting of a reminding alarm sound.

As shown in fig. 3, first, after the vehicle is started, the fully automatic parking controller of the vehicle starts to operate to detect whether one or more obstacles exist within a predetermined range of the vehicle by the radars (radar 1, radar 2, … …, radar N (N is a positive integer)) arranged around the vehicle, and in case of the existence of the obstacles, further detects position information and distance information of the one or more obstacles by the radars, and then transmits the information to the 360 vision controller through the CAN network.

Then, the 360 vision controller acquires an image about the one or more obstacles based on the detected position information and distance information of the one or more obstacles after receiving the information of the one or more obstacles transmitted from the full-automatic parking controller, wherein the image of the one or more obstacles is captured by cameras (front camera, left camera, right camera, rear camera) arranged around the vehicle.

The acquired images of the one or more obstacles are then analyzed by a 360 vision controller built-in image recognition algorithm to identify the type of the one or more obstacles.

And finally, if the type of at least one obstacle in the one or more obstacles is identified to be a human and/or an animal, transmitting the position information and the distance information of the at least one obstacle to the video entertainment host. The video entertainment host computer obtains the speed of the vehicle from the ESC module through the CAN network. The alarm sound control module in the audio-visual entertainment host can inquire the volume and the sound source type of the alarm sound which is selected under the conditions of the current vehicle speed and the distance between the barrier and the vehicle according to the database of the corresponding relation between the volume of the alarm sound and the information of the sound source, the vehicle running speed and the at least one barrier which are stored in the alarm sound storage, and then drive a power amplifier driving chip in the audio-visual entertainment host to drive an alarm sound loudspeaker to alarm according to the selected alarm sound volume and the selected sound source.

It should be understood that the above-mentioned process is a process implemented in the case that at least one obstacle within a predetermined range of the vehicle is detected, and if the 360-degree image controller does not recognize that the type of at least one obstacle of the one or more obstacles is a human and/or an animal after the 360-degree image controller analyzes the information transmitted from the fully-automatic parking controller to the 360-degree image controller, a warning sound is not output.

The warning device for a vehicle of the present invention can be applied to various vehicles, preferably, such as electric vehicles or hybrid vehicles.
