[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 a method and a device for automobile safety protection, belonging to the automobile technical field. The method comprises the following steps of: acquiring a radar detection signal, wherein the radar detection signal comprises a detection signal of a radar in a traveling direction of a vehicle; Determining the depth of the road surface in the traveling direction of the vehicle according to the radar detection signal; When the depth of the road surface in the traveling direction of the vehicle is greater than a threshold value, a safety guard signal is output, and the safety guard signal is used to prevent the vehicle from traveling in the traveling direction of the vehicle. A radar detection signal is obtained by scanning a radar provided in the vehicle traveling direction, the road surface depth in the vehicle traveling direction is determined according to the radar detection signal, and a relationship between the road surface depth in the vehicle traveling direction and the magnitude of a threshold value is used to judge whether there are cliffs, steps, or large holes in front or behind the vehicle or not. When there are cliffs, stairs or large holes, thesafety signal is output to prevent the vehicle from driving, which enhances 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...
