Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a method and device, system, electronic device and storage medium for door opening anti-collision. Background Art

[0002] When the driver or passenger of a vehicle gets off the vehicle, they open the door rashly without checking whether there are pedestrians or vehicles coming from behind, which may cause a traffic accident in which the pedestrian or vehicle collides with the door. This type of traffic accident is commonly known as "door opening kill". The current technical solution to prevent door opening kill is mainly to detect objects that may collide with the body sensor, and then issue a collision warning or limit the width of the door opening.

[0069] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0070] The following describes the door opening anti-collision method and device, system, electronic device and storage medium of the embodiments of the present disclosure with reference to the accompanying drawings.

[0071] Figure 1 A schematic flow chart of a door opening anti-collision method provided in an embodiment of the present disclosure.

[0072] like Figure 1 As shown, the method comprises the following steps:

[0073] Step 101 : Based on a preset sensor, a monitoring object within a preset range of a vehicle is monitored, and it is determined whether the monitoring object is a moving object.

[0074] In the embodiments of the present disclosure, the preset sensor may be an image sensor or a laser sensor, which is not limited in the present disclosure. The monitoring object is an object, an animal or a human in the surrounding environment of the vehicle monitored by the preset sensor. The monitoring object in the surrounding environment of the vehicle is monitored by the preset sensor arranged on the vehicle, and it is determined whether the monitoring object is a moving object or a stationary object.

[0075] Step 102: If the monitored object is a moving object, the displacement information of the moving object is obtained.

[0076] In the embodiments of the present disclosure, after determining that the monitored object is a moving target, it is necessary to obtain the displacement information of the moving object. The displacement information may be the speed of the moving object or the distance between the moving object and the vehicle. The displacement information is obtained by a preset sensor on the vehicle, which is not limited by the present disclosure. The moving object is a moving object, animal or human in the surrounding environment of the vehicle, which is not limited by the present disclosure.

[0077] Step 103: Based on the displacement information, determine whether there is a risk of collision between the moving object and the vehicle.

[0078] In an embodiment of the present disclosure, after the displacement information of the moving object is acquired, it is determined whether there is a risk of collision between the moving object and the vehicle according to the acquired displacement information.

[0079] In some embodiments of the present disclosure, since the moving object may be a human being or a vehicle controlled by a human being, its motion characteristics do not conform to the characteristics of typical linear motion; the risk or probability of collision cannot be simply calculated based on the acquired displacement information. The position information is input into the door opening warning model to predict the collision risk.

[0080] Step 104: If there is a risk of collision, the door on the side of the moving object close to the vehicle is locked for a second time.

[0081] In an embodiment of the present disclosure, if it is determined that there is a risk of collision between the moving object and the vehicle, a secondary locking may be performed by controlling the door lock on the vehicle door.

[0082] In some embodiments of the present disclosure, there may be a risk of failure due to the secondary locking method of the door lock on the vehicle door. In order to improve the safety of the door opening warning system, such risks are solved by setting a secondary confirmation lock on the vehicle door. The secondary confirmation lock can be similar to the child lock device on the vehicle, which is not limited by the present disclosure.

[0083] The present disclosure provides a method for preventing collision when opening a door. Based on a preset sensor, a monitoring object within a preset range of a vehicle is monitored, and it is determined whether the monitoring object is a moving object; if the monitoring object is a moving object, the displacement information of the moving object is obtained; based on the displacement information, it is determined whether there is a risk of collision between the moving object and the vehicle; if there is a risk of collision, the door on the side close to the moving object and the vehicle is locked for a second time. Compared with the related art, the embodiment of the present disclosure determines whether there is a risk of collision by obtaining the displacement information of the moving object, and then determines whether to lock the door for a second time; it can ensure that the door will not collide with the moving object, thereby improving the safety of the door opening warning system.

[0084] In order to clearly explain the present embodiment, the present embodiment provides Figure 2 The flowchart of the door opening anti-collision method is shown in FIG.

[0085] like Figure 2 As shown, the method comprises the following steps:

[0086] Step 201 : Based on a preset sensor, a monitoring object within a preset range of the vehicle is monitored, and it is determined whether the monitoring object is a moving object.

[0087] Step 202, when the monitored object is a moving object, based on the preset sensor, obtain the longitudinal distance of the moving object from the vehicle door in the X-axis direction, the lateral distance from the vehicle door in the Y-axis direction, and the moving speed of the moving object.

[0088] Specifically, in the disclosed embodiment, the vehicle is in a spatial rectangular coordinate system with the length direction of the vehicle as the X-axis, the width direction of the vehicle as the Y-axis, the height direction of the vehicle as the Z-axis, and any point of the vehicle as the origin. Figure 3 The preset sensor is a camera installed on the vehicle, and the camera obtains the longitudinal distance D between the moving object and the door, the lateral distance H between the moving object and the door, and the moving speed S of the moving object. It can be understood that if the moving object is a large object such as a vehicle, then when calculating the longitudinal distance and the lateral distance, the calculation is performed based on the principle of the closest distance to the moving object.

[0089] Step 203, calculating the movement time of the moving object to the door position according to the longitudinal distance and the moving speed.

[0090] Specifically, in the embodiment of the present disclosure, based on the moving speed S of the moving object and the longitudinal distance D between the moving object and the vehicle door, the time from the moving object to the current vehicle door is calculated as T=D / S.

[0091] Step 204: If the lateral distance is less than a distance threshold and the movement time is less than a time threshold, it is determined that there is a risk of collision between the moving object and the vehicle.

[0092] As an implementable manner of this embodiment, if the lateral distance is greater than or equal to a distance threshold or the movement time is greater than or equal to a time threshold, it is determined that there is no risk of collision between the moving object and the vehicle.

[0093] For details, please refer to the embodiments of this disclosure. Figure 3 For example, the width occupied by the door after opening is W, the distance threshold is 2W, and the time threshold is 30 seconds; if the lateral distance H is less than 2W and T is less than 30 seconds, it is considered that the moving object is at risk of collision; and the probability of collision is determined based on the above displacement information.

[0094] If the lateral distance H and the movement time T do not meet the above conditions, it is determined that there is no risk of collision between the moving object and the vehicle. For example: if the lateral distance H>2W or T>30 seconds, it is considered that there is no risk of collision. It should be noted that the above description is only exemplary and does not constitute a limitation on the distance threshold and time threshold.

[0095] Step 205, based on the distance corresponding to the distance threshold, the lateral distance and the lateral occupied distance of the door opening, calculate the collision probability of the moving object colliding with the door; and generate warning information of the corresponding level according to the collision probability.

[0096] Specifically, in the embodiment of the present disclosure, when it is determined that the opening of the vehicle door will collide with a moving object, the collision probability of the moving object colliding with the vehicle door is calculated, and corresponding alarm information is generated according to the level of the collision probability.

[0097] For example, please refer to Figure 3 , assuming that the distance corresponding to the distance threshold is L, the lateral distance is Y, and the lateral distance occupied by the door opening is W, then the formula for calculating the probability of collision is:

[0098]

[0099] Among them, P is the probability of collision.

[0100] It should be noted that the premise for calculating the probability of collision is that the risk of collision has been determined and the vehicle doors have been locked for the second time; the purpose of calculating the probability of collision is to generate alarm information of the corresponding level in order to make a reasonable early warning.

[0101] In other embodiments of the present disclosure, the probability of a collision is predicted by inputting the movement information (including lateral distance, moving speed, etc.) of the moving object obtained by a preset sensor into an artificial intelligence prediction model.

[0102] Step 206: If the lateral distance is greater than or equal to a distance threshold or the movement time is greater than or equal to a time threshold, it is determined that there is no risk of collision between the moving object and the vehicle.

[0103] Specifically, in the disclosed embodiment, when the lateral distance H is less than 2W and T is less than 30 seconds, the secondary confirmation lock on the door is controlled to perform secondary locking to prevent the door from colliding with a moving object. The passengers in the car are reminded to perform secondary confirmation, and after confirming that there is no risk of collision, the locking state of the secondary confirmation lock is released.

[0104] Moving objects may collide with the car door, causing damage to the vehicle or other accidents. By locking the car door twice, the possibility of collision can be reduced and the safety of the vehicle and moving objects can be protected.

[0105] Step 207: When the monitored object is a stationary object, obtain the position information of the stationary object.

[0106] Specifically, in the embodiment of the present disclosure, the stationary object is a stationary object, animal or human in the surrounding environment of the vehicle, and the present disclosure is not limited to this. By obtaining the position information of the stationary object, it is determined whether there is a risk of collision between the stationary object and the vehicle door.

[0107] Step 208 , judging whether to perform secondary locking on the door corresponding to the stationary object according to the first spatial position information and the pre-stored second spatial position information of the door being opened and occupied.

[0108] As an achievable method of this embodiment, the first spatial position information and the second spatial position information are compared and processed based on the spatial rectangular coordinate system; if it is determined that the stationary object intrudes into the space occupied by the door opening, it is determined that the door corresponding to the stationary object is locked for the second time.

[0109] Specifically, in the disclosed embodiment, the acquired position information is compared with the space occupied by the door opening to determine whether the door opening trajectory is on the track and whether the stationary object will collide with the door. If there is a possibility of collision, the door corresponding to the stationary object is locked for the second time. If there is no possibility of collision, no processing is performed.

[0110] Furthermore, as an achievable method of the embodiment of the present disclosure, when a door is close to a moving object and is open, if another door on the same side is to be opened at this time, the following measures are taken: if the door on the side close to the moving object and the vehicle has been opened and the opened door is close to the moving object, the other door on the side close to the moving object is released from the secondary lock.

[0111] Specifically, in the embodiment of the present disclosure, when a vehicle door is close to a moving object and is open, if another vehicle door on the same side is to be opened at this time, the locking state of the secondary confirmation lock corresponding to the vehicle door is released.

[0112] It should be specifically mentioned that in the embodiments of the present disclosure, multiple steps may be included. For the convenience of description, these steps are numbered, but these numbers are not limitations on the execution time slots and execution order between the steps; these steps can be implemented in any order, and the embodiments of the present disclosure are not limited to this.
