[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

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

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

[0030] A processing module receives the deep pit information from the acquisition module and generates warning information after processing the deep pit information;

[0031] A control module generates a protective action for the vehicle 10 according to the warning information;

[0032] The execution module executes the protection action of the vehicle 10.

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

[0034] Moreover, in this embodiment, the width of the vehicle 10 is the first distance D1, and the time interval between the first laser radar 211 and the second laser radar 212 is D2.

[0035] Furthermore, in this embodiment, the relationship between the first distance D1 and the second distance D2 mentioned above is: D2 ≥ 0.5D1; so that the first laser radar 211 and the second laser radar 212 have a sufficient distance to reduce the measurement error.

[0036] In this embodiment, the laser radar further includes a third laser radar 221 and a fourth laser radar 222, and the third laser radar 221 and the fourth laser radar 222 are arranged in parallel;

[0037] The plane where the first laser radar 211 and the second laser radar 212 are located is the first plane, the plane where the third laser radar 221 and the fourth laser radar 222 are located is the second plane, and the first plane is above the second plane.

[0038] Specifically, the first plane and the second plane have an angle, so that the angles detected by the first group of laser radars 21 and the first group of laser radars 22 are different, so that the accuracy of deep pit information recognition is improved by analyzing the data of the two groups.

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

[0040] The laser radar also includes a fifth laser radar 23 arranged parallel to the bottom end of the vehicle 10, wherein the receiving end of the laser radar can receive the laser emitted by the transmitting end and reflected back by the pit wall in the deep pit, thereby obtaining the position information of the deep pit, and the position information includes the distance and direction from the vehicle 10.

[0041] When the vehicle 10 is driving, it encounters a deep pit in front. Since the angle between the third group of laser radars and the horizontal plane is small, the third laser radar 221 and the fourth laser radar 222 inside it begin to detect the front and rear boundaries of the deep pit to determine the front and rear width of the deep pit, and at the same time detect whether the third laser radar 221 and the fourth laser radar 222 are fully illuminated into the deep pit, so as to determine whether the width of the vehicle 10 can be greater than the length of the deep pit, and control the vehicle 10 to perform designated safety protection actions through the vehicle control system.

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

[0043] Specifically, the protective action of the vehicle 10 includes any one or more of deceleration, lane change, parking, and turning on lights.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. It should also be noted that the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0045] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the device embodiment, since it is based on a similar method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
