Embodiment Construction

[0032]The following are specific embodiments of the present invention, and further describe the technical solution of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0033] Such as figure 1 As shown, the car includes a radar 1, an on-board controller 5 and an automatic emergency braking system 5. The radar 1 is used to detect obstacles, and the on-board controller 5 is used to control the automatic emergency braking system 6. The device for malfunctioning due to small obstacles includes a sampling module 2 , an obstacle analysis module 3 and a filtering module 4 . The sampling module 2 is used to sample the detection results of the radar 1, obtain the sample RCS of each sampling period, and record, for example, record as RCS_1, RCS_2, RCS_3...RCS_N, in this embodiment, N represents the current moment, as the vehicle During the driving process, the radar 1 has been detecting, and then the sam...

Abstract

The invention provides a device and method for preventing an automatic emergency braking system from conducting misoperation on small barriers and belongs to the technical field of automotive electronics. By means of the device and method, the problem that in the prior art, automatic emergency braking systems conduct misoperation on small barriers is solved. The device comprises a sampling module, a barrier analysis module and a filtering module, wherein the sampling module is used for sampling radar detection results; the barrier analysis module is used for analyzing sampling results; and the filtering module is used for filtering out small barrier information. The control method comprises the steps that the radar detection results are sampled; samples RCS are analyzed to judge the size of the barriers; and the small barrier information is filtered out, large barrier information is transmitted to a vehicle-mounted controller, and the vehicle-mounted controller controls the automobile emergency braking system to perform braking operation. Through the device and method, the sizes of the barriers detected by radar can be judged, the useless small barrier information is filtered out, and the automatic emergency braking system is prevented from conducting misoperation on the small barriers.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and relates to a device and a method for suppressing the malfunction of an automatic emergency braking system for small obstacles. Background technique [0002] The automatic emergency braking system (AEB) uses the 77GHZ radar sensor installed in front of the vehicle to sense the surrounding environment during the driving process of the vehicle, identify, detect and track the target object, and automatically take braking measures in emergency situations , so as to help drivers reduce or avoid collision risks and improve driving safety. [0003] In order to ensure that the automatic emergency braking system has a high correct trigger rate for moving objects, the traditional radar system only judges its moving speed, and when the moving speed exceeds the threshold, it is judged as a valid target. However, the actual road conditions in China are complex and diverse. During driving, t...
