[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] like Figure 1 As shown, this application embodiment provides a safety system for a vehicle 10, applied to the vehicle 10, and includes the following modules:

[0029] The acquisition module is used to monitor the deep pit information in front of vehicle 10;

[0030] The processing module receives the deep pit information from the acquisition module, processes the deep pit information, and generates early warning information.

[0031] The control module generates vehicle protection actions based on the aforementioned warning information.

[0032] The execution module performs the protective actions of vehicle 10.

[0033] The acquisition module includes lidar 20 located at the top and bottom of the front end of the vehicle 10. The lidar 20 at the top of the vehicle 10 includes a first set of lidar 21 and a first set of lidar 22, while the lidar 20 at the bottom of the vehicle 10 includes at least a fifth lidar 23. Specifically, the first set of lidar 21 includes a first lidar 211 and a second lidar 212, and the first set of lidar 22 includes a third lidar 221 and a fourth lidar 222.

[0034] Furthermore, in this embodiment, the width of the vehicle 10 is the first spacing D1, and the time spacing between the first lidar 211 and the second lidar 212 is D2.

[0035] Furthermore, in this embodiment, the relationship between the first spacing D1 and the second spacing D2 is: D2≥0.5D1; so that the first lidar 211 and the second lidar 212 have sufficient spacing to reduce measurement errors.

[0036] In this embodiment, the lidar further includes a third lidar 221 and a fourth lidar 222, which are arranged side by side;

[0037] The plane in which the first lidar 211 and the second lidar 212 are located is the first plane, and the plane in which the third lidar 221 and the fourth lidar 222 are located is the second plane. The first plane is above the second plane.

[0038] Specifically, the first plane and the second plane have an angle between them, which makes the angles detected by the first group of lidar 21 and the first group of lidar 22 different. By analyzing the data from the two groups, the accuracy of deep pit information identification can be improved.

[0039] In this embodiment, the warning information includes the width of the pit.

[0040] The lidar also includes a fifth lidar 23 disposed parallel to the bottom of the vehicle 10. The receiving end of the lidar can receive the laser emitted by the transmitting end and reflected back by the pit wall in the pit, thereby obtaining the location information of the pit. The location information includes the distance from the vehicle 10 and the orientation.

[0041] When vehicle 10 is driving, it encounters a deep pit ahead. Because the angle between the third set of lidar and the horizontal plane is small, the third lidar 221 and the fourth lidar 222 inside the lidar begin to detect the front and rear boundaries of the pit to determine the front and rear width of the pit. At the same time, it detects whether the third lidar 221 and the fourth lidar 222 have completely illuminated the inside of the pit to determine whether the width of vehicle 10 is greater than the length of the pit. Then, the vehicle control system controls vehicle 10 to perform the specified safety protection action.

[0042] Specifically, the warning information includes any one or more of lane change information, deceleration information, parking information, and headlight activation information;

[0043] Specifically, the protective actions of the vehicle 10 include any one or more of the following: deceleration, lane change, stopping, and turning on the lights.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
