Abstract

Disclosed are a vehicle collision processing device, method and control device, relating to the technical field of unmanned vehicles. The device includes: a collision sensor, which is used to provide a collision signal in the event of a vehicle collision; a signal holder, which is used to maintain a collision signal for a preset period of time to provide a continuous signal of the collision signal; a brake actuator, which is used to continuously The signal acts as a trigger signal to provide braking force to brake the vehicle. The processing device of the embodiment of the present invention uses the signal holder to provide the continuous signal of the collision signal during the unmanned driving process, and directly uses the continuous signal to trigger the brake actuator to provide the braking force, which reduces the information transmission link of the collision signal and improves the automatic Braking efficiency of unmanned vehicles during driving.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to a vehicle collision processing device, method and control device. Background technique [0002] Unmanned vehicles are fully unmanned during operation, and vehicle handling stability and driving safety are of utmost importance. Collision sensors are integrated in many unmanned vehicles, which can be used to monitor whether the unmanned vehicle collides with obstacles. According to the controller area network (CAN) bus protocol, the collision signal output by the collision sensor communicates with the vehicle controller (VCU) through the controller area network (CAN) bus. The vehicle controller (VCU) provides a continuous signal whose signal value remains for a preset time according to the collision signal, and provides the continuous signal to the electronic parking brake system (EPB) to brake the unmanned vehicle. Obviously, when an unmanned vehicle collides, the coll...
