Technical Field

The invention relates to the technical field of traffic safety, in particular to a door opening anti-collision method of a vehicle, a door opening anti-collision device of the vehicle, a computer readable storage medium, electronic equipment, the vehicle and a door opening anti-collision system of the vehicle.

Background

When a passenger gets off the vehicle and opens the door, due to the reasons of insufficient observation of a moving object behind and the like, accidents of collision between the passenger and a vehicle and pedestrians behind occur frequently, and serious passengers can also cause casualties.

At present, the mode for preventing the accidents is mainly that passengers subjectively observe the rear traffic condition and ensure that no vehicle can open the door and get off the vehicle when no vehicle is in the rear. In the related technology, a radar and a camera are mostly adopted or an electronic sensor is additionally arranged to detect the distance between an automobile and a rear obstacle and the moving speed of the obstacle, and a door opening anti-collision system is formed by a CAN bus module, an information preprocessing module, a door lock driving module, a door lock executing module, a door opening anti-collision control ECU (electronic control unit) and the obstacle detecting module. When the system detects that the rear part of the vehicle is provided with a moving non-motor vehicle and a pedestrian, the system judges that the door is not provided with a door opening condition, and triggers an alarm device.

However, the related art solution has the following disadvantages: the rear obstacle category cannot be accurately identified, and the static obstacle is easily identified as a pedestrian or a vehicle by mistake due to the close sensing distance, so that false alarm is caused; the alarm reminding is not timely, and when the barrier moves at a high speed, the phenomenon that the barrier is not recognized and the door is opened and collided easily occurs; in order to achieve the purpose of accurately identifying obstacles behind the vehicle, a camera, a laser radar, a millimeter wave radar and other sensors need to be installed, so that the cost is high; inaccurate identification and prediction of vulnerable traffic participants results in false positives.

The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following describes a vehicle and a door opening collision avoidance method, a system, a device, an electronic device and a medium thereof according to an embodiment of the invention with reference to fig. 1 to 4.

Fig. 1 is a schematic flow chart of a door opening collision avoidance method of a vehicle according to an embodiment of the present invention. As shown in fig. 2, the door opening collision avoidance method of the vehicle includes:

s101, acquiring motion information of the current vehicle, and acquiring perception information of vehicles around the current vehicle and the drive test equipment through a V2X communication system.

Specifically, the motion information of the current vehicle may be acquired by a vehicle speed sensor, a navigation system, or the like, wherein the motion information of the current vehicle includes first pre-travel track information of the current vehicle, the first pre-travel track information being obtained by aggregating paths { nodes }₁，node₂… } in which, node_iFor the ith on the first pre-travel trackTrack point information, node_i＝[x_i，y_i，v_i，theta_i]，i＝0，1，2，…，x_iIs the abscissa, y, of the ith locus point in a Cartesian coordinate system_iIs the ordinate, v, of the ith locus point in a Cartesian coordinate system_iThe point speed, theta, of the current vehicle at the ith track point_iThe heading angle of the ith track point (the origin can be the true east, and the north is true). Perception information (such as coordinate position, speed, driving direction and the like of a non-motorized vehicle and a pedestrian behind the current vehicle) of a vehicle and a roadside unit RSU device which are also equipped with the V2X communication system is obtained through the V2X communication system. The V2X communication system can utilize LTE-V communication or 5G communication for data transmission. The perception information comprises second pre-driving track information of a target collision-proof object behind the current vehicle, and the second pre-driving track information passes through a position coordinate vector pos [ (x)_P1，y_P1)，(x_P2，y_P2)，…]Is represented by, wherein x_PiIs the abscissa, y, of the ith track point on the second pre-travel track in a Cartesian coordinate system_PiIs the ordinate of the ith track point in a Cartesian coordinate system,

x_P(i+1)＝v_P·cos(theta_P)·Δt_i+1+x_Pi，i＝0，1，2，…，

y_P(i+1)＝v_P·sin(theta_P)·Δt_i+1+y_Pi，i＝0，1，2，…，V_Pis the speed of the target impact, theta_PIs the advancing direction angle (which can be from the east to the north) of the target anticollision object, and is Deltat_i+1Is the time difference from the i +1 th track point to the i th track point, delta t_i+1＝(y_i+1-y_i)/(v_i·cos theta_i)，t₀Is the initial time.

As an example, the method may further comprise: acquiring control information of a current vehicle, and judging whether the current vehicle has a driving and stopping trend according to the control information, wherein the control information comprises accelerator pedal information, brake pedal information and steering wheel corner information; and if the current vehicle is judged to have the driving and stopping tendency, acquiring the motion information of the current vehicle, and acquiring the perception information of the vehicles around the current vehicle and the drive test equipment through the V2X communication system.

Specifically, whether the current vehicle has a driving and stopping trend is judged by detecting the current information of an accelerator pedal, the current information of a brake pedal and the current information of a steering wheel angle of the vehicle. If the opening degree of the accelerator pedal is smaller than or equal to a first preset opening degree, the opening degree of the brake pedal is larger than or equal to a second preset opening degree, and the steering wheel angle is smaller than a preset steering angle, the vehicle is judged to have a driving and stopping trend, at the moment, motion information such as the current vehicle speed, acceleration, coordinates, a predicted track point and the like can be obtained, perception information of vehicles around the current vehicle and road measurement equipment is also obtained through a V2X communication system, and step S101 is executed, so that unnecessary door opening anti-collision detection can be avoided to a certain extent. The first preset opening degree is smaller than the second preset opening degree, and the first preset opening degree, the second preset opening degree and the preset rotation angle can be calibrated according to requirements.

And S102, calculating the distance between the current vehicle and the rear target collision-proof object according to the motion information and the perception information of the current vehicle.

Specifically, take pedestrian P as an example, let x_P0Is the abscissa, y, of the pedestrian P (i.e., the rear target bumper) under the Cartesian coordinate system at the present moment_P0Is the ordinate, v, of the pedestrian P in a Cartesian coordinate system_PIs the speed of the pedestrian, theta_PIs the heading angle (with the true east as the starting point and the north as the positive). According to the perception information, calculating a predicted position coordinate vector pos [ (x) of the pedestrian under the time vector t_P1，y_P1)，(x_P2，y_P2)，…]，

x_P(i+1)＝v_P·cos(theta_P)·Δt_i+1+x_Pi，i＝0，1，2，…

y_P(i+1)＝v_P·sin(theta_P)·Δt_i+1+y_Pi，i＝0，1，2，…

Calculating a distance vector Dis [ Dis ] of a pedestrian and a current autonomous vehicle₁，dis₂，…]

dis_i＝sqrt((x_Pi-x_i)²+(y_Pi-y_i)²)，i＝0，1，2，…

Thus, according to the formula dis_i＝sqrt((x_Pi-x_i)²+(y_Pi-y_i)²) And i is 0, 1, 2, …, calculating the distance between the current vehicle and the rear target collision object. And the calculation result can be corrected and updated according to the motion information of the current automatic driving vehicle and the perception information of vehicles around the current vehicle and the drive test equipment, and the calculation process is repeated to obtain the latest distance between the pedestrian and the current automatic driving vehicle.

S103, when the door opening intention of the passenger of the current vehicle is determined, whether the distance between the current vehicle and the rear target collision object is smaller than a preset safety threshold value or not is judged.

Specifically, when two conditions that the current vehicle speed is zero and a passenger touches a door opener (which can be determined according to an image detection device installed in the vehicle or according to a sensing signal of a sensor installed on the door opener) are met, it is determined that the passenger of the current vehicle has an intention to open the door, and at this time, it can be determined whether the distance between the automatically-driven vehicle and a rear non-motor vehicle and a pedestrian (i.e., a rear target collision object) at the current time is smaller than a set threshold value. For example: when the vehicle speed is zero and a sensor signal (i.e., an intention to open the door) that the passenger touches the door handle is received, it is determined that the time t is_xThe distance dis between the pedestrian and the vehicle_iAnd whether the value is less than a preset safety threshold epsilon, wherein x is more than or equal to i and less than i + 1.

And S104, if the distance between the current vehicle and the rear target collision-proof object is smaller than a preset safety threshold value, sending out early warning information.

Specifically, if the distance dis between the pedestrian (i.e. the rear target collision-prevention object) and the host vehicle (i.e. the current vehicle) is smaller than the preset safety threshold epsilon, the early warning device (such as the vehicle-mounted display terminal and the mobile terminal of the user) can be triggered to perform early warning prompt of the dangerous situation on the driver and the passengers by means of sound, images and the like, for example: the words and/or the voice 'please pay attention to the pedestrian behind when the door is opened' can remind the passenger to pay attention to the safety of opening the door.

In conclusion, according to the door opening anti-collision method for the vehicle, the distance between the current vehicle and the rear target collision object is calculated according to the motion information and the perception information of the current vehicle, so that the driving safety is improved, the traffic efficiency is improved, and the probability of the door opening collision accident of the automobile is reduced.

After obtaining the motion information and the perception information of the current vehicle, the calculation module 12 may calculate the distance according to the formula dis_i＝sqrt((x_Pi-x_i)²+(y_Pi-y_i)²) And i is 0, 1, 2, …, calculating the distance between the current vehicle and the rear target collision object. The determining module 13 may further determine whether the distance between the current vehicle and the rear target collision-proof object is less than a preset safety threshold when the current vehicle speed is zero and the sensor signal that the passenger touches the door handle is received (i.e. the passenger has an intention to open the door). When the distance between the current vehicle and the rear target collision-proof object is smaller than the preset safety threshold, the early warning module 14 may send out early warning information, such as: the early warning prompt of dangerous conditions is carried out on a driver and passengers by means of sound, images and the like, and the problem that when the barrier moves at a high speed, the barrier is not recognized and the door is opened and collides is solved.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise explicitly specified or limited, a first feature may be "on" or "under" a second feature in direct contact with the first and second features, or in indirect contact with the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
