[0003] However, the current AEB system is mainly concerned with the situation above the front and rear of the vehicle. However, when there are cliffs, stairs or large potholes below the front and rear of the vehicle that may cause the vehicle to fall, the AEB system will not work. There are still major safety issues in the vehicle

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 It is a flow chart of an automobile safety protection method provided by an embodiment of the present invention. see figure 1 , automobile safety protection methods include:

[0027] Step 101: Obtain a radar detection signal, the radar detection signal includes a detection signal of the radar in the traveling direction of the vehicle.

[0028] Specifically, the radar detection signal may include at least one of a detection signal of a front radar and a detection signal of a rear radar.

[0029] Among them, the front radar is used to detect the road conditions in front of the car, and the rear radar is used to detect the road conditions behind the car. The front of the car is the side toward which the front of the ca...

Abstract

The invention discloses an automobile safety protection method and device, which belongs to the technical field of automobiles. The method includes: acquiring a radar detection signal, which includes a radar detection signal in the vehicle's direction of travel; determining the road surface depth in the vehicle's direction of travel based on the radar detection signal; when the road surface depth in the vehicle's direction of travel is greater than a threshold, output safety Protection signal, safety protection signal is used to prevent vehicles from traveling in the direction of travel of the vehicle. By setting up a radar to scan in the direction of vehicle travel, the radar detection signal is obtained, and the depth of the road surface in the direction of vehicle travel is determined based on the radar detection signal. Based on the relationship between the depth of the road surface in the direction of vehicle travel and the threshold, it is judged whether there is anything in front or behind the vehicle. Cliffs, stairs or larger potholes, etc. When there are cliffs, stairs or large potholes, a safety protection signal is output to prevent the vehicle from driving and enhance the safety of the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile safety protection method and device. Background technique [0002] At present, most vehicles are equipped with an Autonomous Emergency Braking (AEB) system. Its important function is to take emergency braking when the system judges that there is an obstacle in front or behind the vehicle and there is a risk of collision. [0003] However, the current AEB system is mainly concerned with the situation above the front and rear of the vehicle. However, when there are cliffs, stairs or large potholes below the front and rear of the vehicle that may cause the vehicle to fall, the AEB system will not work. As a result, there are still major safety issues in the vehicle. Contents of the invention [0004] Embodiments of the present invention provide a method and device for automobile safety protection, which are used to solve vehicle safety problems when there are cl...
