VRU motion triggering system and method in automobile AEB test

Abstract

The invention discloses a VRU motion triggering system and a VRU motion triggering method in an automobile AEB test, which belong to the field of driving assistance systems. The VRU motion triggeringsystem comprises a controller, a radar, a driving unit, a traction device and a dummy device, wherein the radar is used for detecting a moving speed of the target vehicle and a distance between the target vehicle and the dummy device VRU; the controller is used for acquiring collision time of the target vehicle and the dummy device VRU according to the moving speed of the target vehicle and the distance between the target vehicle and the dummy device VRU, and sending a driving signal to the driving unit when the collision time is less than or equal to preset time; the driving unit is used forsending a trigger signal to the traction device after receiving the driving signal; and the traction device is used for controlling and pulling the dummy device VRU to move according to a preset speedand a preset direction under the driving action of the driving unit after receiving the trigger signal. The VRU motion triggering system and the VRU motion triggering method are low in implementationcost, and meet the requirements of AEB pedestrian tests simply and efficiently.

Description

technical field [0001] The invention belongs to the field of driving assistance systems, and more specifically relates to a VRU motion triggering system and method in an automobile AEB test. Background technique [0002] Automatic emergency braking (Autonomous Emergency Braking, AEB) system uses radar to measure the distance to the vehicle or obstacle in front, and then uses the data analysis module to compare the measured distance with the warning distance and safety distance, and then proceeds when it is less than the warning distance The alarm prompts, and even if the driver does not have time to step on the brake pedal when the distance is less than the safety distance, the AEB system of the vehicle will be activated to enable the car to brake automatically, thereby avoiding a collision or reducing the degree of collision damage. [0003] like figure 1 As shown, the current method to realize the AEB pedestrian function test is to use the differential GPS positioning sys...
