[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The following description, with reference to the accompanying drawings, outlines a method, device, vehicle, storage medium, and program for providing a door collision avoidance warning according to embodiments of this application. Addressing the problem mentioned in the background section of related technologies where narrow parking spaces or improper parking lead to inexperienced occupants easily colliding with the doors of adjacent vehicles when opening their doors, causing losses, disputes, and negatively impacting user experience, this application provides a door collision avoidance warning method. In this method, the maximum opening distance of each door is calculated based on the lateral distance between the vehicle and each door of adjacent vehicles, as well as the door size information. A reference value for the size occupied by the user when exiting the vehicle is determined based on the body size data of the occupants. A corresponding warning action is executed based on the reference value and the maximum opening distance of the door, preventing collisions with the doors of adjacent vehicles due to inexperience caused by narrow parking spaces or improper parking, thus improving the user experience. This solves the problem in related technologies where narrow parking spaces or improper parking lead to inexperienced occupants easily colliding with the doors of adjacent vehicles when opening their doors, causing losses, disputes, and negatively impacting user experience.

[0025] Specifically, Figure 1 This is a flowchart illustrating a vehicle door anti-collision warning method provided in an embodiment of this application.

[0026] like Figure 1 As shown, the door collision avoidance warning method includes the following steps:

[0027] In step S101, the lateral distance and door size information of each door corresponding to the vehicle and the adjacent parking space are obtained.

[0028] It is understood that the embodiments of this application can obtain the lateral distance between each door of the vehicle and the adjacent vehicle through the lidar device, and obtain the door size information through the vehicle system, so as to calculate the maximum opening distance of the corresponding door based on the lateral distance and door size information.

[0029] It should be noted that the lateral distance detection trigger condition is consistent with the reversing radar trigger condition. In addition, since the vehicle has four doors, the corresponding lidar device on each door needs to detect the lateral distance between the corresponding door and the vehicle in the adjacent parking space.

[0030] In this embodiment of the application, it is also included: updating the lateral distance between each door of the vehicle and the adjacent vehicle at preset intervals.

[0031] The preset duration can be set according to the user's actual needs, such as 1 second or 2 seconds, without any specific limitation.

[0032] It is understood that the embodiments of this application can update the lateral distance between each door of the vehicle and the adjacent vehicles at preset intervals, and obtain data in real time for calculation, so as to provide timely warnings and improve the user experience.

[0033] It should be noted that the lidar device in this application continuously detects the distance to vehicles on the side, and the detection time is once every 1 second.

[0034] In step S102, the maximum opening distance of the corresponding door is calculated based on the lateral distance and door size information.

[0035] It is understood that the embodiments of this application can calculate the maximum opening distance of the corresponding door based on the lateral distance and door size information, so as to perform the corresponding target action according to the user's exit size reference value and the maximum opening distance of the door.

[0036] In this embodiment of the application, the maximum opening distance of the corresponding door is calculated based on the lateral distance and door size information, including: identifying the door length of the door size information; calculating the maximum opening angle of the door based on the door length and lateral distance; and calculating the maximum opening distance of the door based on the maximum opening angle and door length.

[0037] It is understood that the embodiments of this application can identify the door length of the door size information; calculate the maximum opening angle of the door based on the door length and lateral distance; and calculate the maximum opening distance of the door based on the maximum opening angle and door length, so as to perform the corresponding target action according to the size reference value occupied by the user getting out of the car and the maximum opening distance of the door.

[0038] It should be noted that the central control system receives distance information and continuously calculates the door opening angle and opening degree based on the door size information.

[0039] Specifically, such as Figure 2 As shown, assuming the length of the car door is L, the maximum safe opening angle of the car door is θ, and the maximum opening distance of the car door is K; then the maximum opening distance of the car door is K = L•cosθ.

[0040] In step S103, the body shape data of the people inside the vehicle is identified, and the reference value of the size occupied by the user when getting out of the vehicle is determined based on the body shape data of the people inside the vehicle.

[0041] It is understood that the embodiments of this application can identify the body shape data of the people inside the vehicle and determine the reference value of the size occupied by the user when getting out of the vehicle based on the body shape data of the people inside the vehicle, so as to perform the corresponding target action according to the reference value of the size occupied by the user when getting out of the vehicle and the maximum opening distance of the door.

[0042] It should be noted that multiple cameras inside the vehicle detect the body shape data of the people in each seat, and determine the reference size value for the user to get out of the vehicle based on the body shape data of the people in the vehicle. Since people have different body shapes, the corresponding door opening angle will also be different.

[0043] In this embodiment of the application, determining the reference value of the size occupied by the user when getting out of the vehicle based on the body shape data of the occupants includes: identifying the frontal and side dimensions of the body shape data of the occupants; and calculating the reference value of the size occupied by the user when getting out of the vehicle based on the frontal and side dimensions.

[0044] It is understood that the embodiments of this application can identify the frontal and side dimensions of the body data of the occupants in the vehicle; and calculate the reference value of the size occupied by the user when getting out of the vehicle based on the frontal and side dimensions, so as to make the subsequent warning information more accurate.

[0045] Specifically, a) Based on the in-vehicle OMS (Occupant Monitoring System) camera, the body shape and size information of the occupants are determined, and the side width of the human body is estimated. The maximum side width is used as the estimated side dimension. b) Because occupants cannot completely turn sideways when exiting the vehicle, the dimensions involved will fall between the front and side views. Therefore, the estimated width for exiting the vehicle is calculated as 100% of the side width + 50% of the front width. Assuming C is the side width and Z is the front width, the estimated width for exiting the vehicle is P = C + Z × 50%.

[0046] In step S104, the corresponding target action is performed based on the user's exit vehicle occupancy dimension reference value and the maximum door opening distance.

[0047] It is understood that the embodiments of this application can perform corresponding target actions based on the reference value of the size occupied by the user getting out of the car and the maximum opening distance of the car door, so as to avoid the situation where the people in the car collide with the doors of adjacent vehicles due to lack of experience when opening the door because the parking space is too narrow or the vehicle is not parked properly, thereby improving the user experience.

[0048] In this embodiment of the application, before performing the corresponding target operation based on the user's exit space reference value and the maximum door opening distance, the method includes: correcting the user's exit space reference value according to a preset correction ratio to generate corresponding first to third user exit space reference values.

[0049] The preset correction ratio can be 30%-100%, and can be selected according to actual needs without specific limitations.

[0050] It can be understood that the embodiments of the present application can correct the user's getting-off occupancy size reference value according to a preset correction ratio to generate corresponding first to third user getting-off occupancy size reference values, so as to improve the accuracy of the collision possibility.

[0051] It should be noted that the first user getting-off occupancy size reference value is P×(1 + 50%), the second user getting-off occupancy size reference value is P×(1 + 70%), and the third user getting-off occupancy size reference value is P×(1 + 100%).

[0052] In the embodiments of the present application, corresponding target actions are performed according to the user's getting-off occupancy size reference value and the maximum opening distance of the door, including: if the maximum opening distance of the door is less than or equal to the first user getting-off occupancy size reference value, controlling the collision warning to reach the first level; if the maximum opening distance of the door is greater than the first user getting-off occupancy size reference value and less than or equal to the second user getting-off occupancy size reference value, controlling the collision warning to reach the second level; if the maximum opening distance of the door is greater than the second user getting-off occupancy size reference value and less than or equal to the third user getting-off occupancy size reference value, controlling the collision warning to reach the third level; if the maximum opening distance of the door is greater than the third user getting-off occupancy size reference value, not responding to the collision warning.

[0053] It can be understood that the embodiments of the present application can determine to control the collision warning to reach the corresponding level according to the comparison value between the maximum opening distance of the door and the first to third user getting-off occupancy size reference values, avoiding the situation that when the vehicle occupants open the door due to lack of experience and collide with the door of the adjacent vehicle due to a narrow parking space or irregular vehicle parking, and improving the user experience.

[0054] It should be noted that the first level can be the highest level, the second level can be the intermediate level, and the third level can be the low level.

[0055] Specifically, through the above judgment of the door opening angle and opening distance, assuming the opening distance is K; since the OMS's judgment of the human body size may not be accurate, a certain correction ratio needs to be added, and a margin of 30% - 100% is provided as a parameter for reminding the collision possibility, that is:

[0056] 1) When the calculated available opening K ≤ P×(1 + 50%), the collision warning is at the highest level;

[0057] 2) When the calculated available opening P×(1 + 50%) < K ≤ P×(1 + 70%), the collision warning is at the intermediate level;

[0058] 3) When the calculated available opening P×(1 + 70%) < K ≤ P×(1 + 100%), the collision warning is at the low level;

[0059] 4) The calculated openable K > P × (1 + 100%), so there is no need for collision warning.

[0060] According to the door collision avoidance reminder method proposed in this application, the maximum opening distance of the corresponding door is calculated based on the lateral distance between the vehicle and each door of the adjacent vehicle and the door size information. The reference value of the size occupied by the user when getting out of the vehicle is determined based on the body size data of the occupants. The corresponding warning action is executed based on the reference value of the size occupied by the user when getting out of the vehicle and the maximum opening distance of the door. This avoids collisions between the occupants of the vehicle and the doors of adjacent vehicles due to insufficient experience when opening the door because of narrow parking spaces or improper parking, thereby improving the user experience.

[0061] The following will combine Figure 1 and Figure 2 The method for providing collision avoidance warning for vehicle doors in this application is described in detail, and the specific steps are as follows:

[0062] Step 1, during the parking process:

[0063] a) Lateral distance detection trigger conditions: consistent with the reversing radar trigger conditions.

[0064] b) Continuously detect the distance to vehicles on the side, with a detection time of once every 1 second.

[0065] c) The central control system receives distance information and continuously calculates the opening angle and opening degree based on the door size information.

[0066] d) Based on the standard side dimensions of the human body, provide a 100% margin (due to differences in body size).

[0067] e) If the opening is greater than the side dimension of the human body (including 100% margin), no prompt will be given; if it is less than the side dimension, the user will be prompted by the vehicle's infotainment system.

[0068] Step 2, after parking:

[0069] If the prompt criteria are met before the vehicle is turned off, the system will continuously prompt the user.

[0070] Step 3, regarding the determination of human side profile dimensions:

[0071] a) Based on the in-vehicle OMS camera, determine the body shape and size information of the people in the vehicle, and infer the side width of the human body. At the same time, the side dimension is taken as the maximum side dimension of the human body.

[0072] b) Since it is impossible for a person to get off the vehicle completely sideways, when getting off the vehicle, the dimensions involved will be between the front and the side. Therefore, it is necessary to use 100% of the side dimension + 50% of the front dimension as the width dimension occupied when getting off the vehicle as the estimation benchmark. Assuming C is the side dimension of the human body and Z is the front dimension of the human body, the dimension benchmark P for getting off the vehicle is P = C + Z × 50%.

[0073] c) Through the above judgment of the door opening angle and the opening distance, assuming the opening distance is K.

[0074] d) The judgment of the human body dimensions by the OMS may not be accurate. Therefore, it is necessary to add a certain correction ratio and provide a margin of 30% - 100% as a parameter to remind of the possibility of collision, that is:

[0075] When the calculated available opening K ≤ P×(1 + 50%), the collision warning is at the highest level;

[0076] When the calculated available opening P×(1 + 50%) < K ≤ P×(1 + 70%), the collision warning is at the intermediate level;

[0077] When the calculated available opening P×(1 + 70%) < K ≤ P×(1 + 100%), the collision warning is at the low level;

[0078] When the calculated available opening K > P×(1 + 100%), no collision warning is required.

[0079] In summary, by installing a lidar device on the side of the vehicle, detecting the distance of the vehicle on the side when parking, after obtaining the distance, calculating the available opening angle according to the door length, and then judging whether this angle allows normal entry and exit of people; according to the average body width of people in the side direction, giving a percentage probability reminder of whether a collision may occur, it is possible to detect the vehicle on the side and make a judgment based on the size of its own door, giving the probability of collision instead of an absolute warning, because the body size and the way of getting off the vehicle of each person are different; avoiding the situation where the passengers in the vehicle collide with the doors of adjacent vehicles due to lack of experience when opening the door due to a narrow parking space or irregular vehicle parking, thus improving the user experience.

[0080] Next, refer to the accompanying drawings to describe the door anti - collision reminder device according to the embodiments of the present application.

Based on the body size data of the occupants, the reference value of the size occupied by the user when getting out of the vehicle is determined. Based on the reference value of the size occupied by the user when getting out of the vehicle and the maximum opening distance of the door, the corresponding warning action is executed to avoid the occupants of the vehicle from colliding with the door of the adjacent vehicle due to lack of experience when opening the door due to the narrow parking space or improper parking, thereby improving the user experience.

Before performing the corresponding target action based on the user alighting space occupancy reference value and the maximum opening distance of the door, the module includes: correcting the user alighting space occupancy reference value according to a preset correction ratio to generate corresponding first to third user alighting space occupancy reference values. The step of executing the corresponding target action based on the user's exit vehicle occupancy reference value and the maximum door opening distance includes: if the maximum door opening distance is less than or equal to the first user's exit vehicle occupancy reference value, then controlling the collision warning to reach the first level; if the maximum door opening distance is greater than the first user's exit vehicle occupancy reference value and less than or equal to the second user's exit vehicle occupancy reference value, then controlling the collision warning to reach the second level; if the maximum door opening distance is greater than the second user's exit vehicle occupancy reference value and less than or equal to the third user's exit vehicle occupancy reference value, then controlling the collision warning to reach the third level; if the maximum door opening distance is greater than the third user's exit vehicle occupancy reference value, then not responding to the collision warning.
