The invention discloses an automatic driving brake-by-wire system. When the vehicle is in the automatic driving mode, if speed reduction is needed, the vehicle control unit can determine the braking pressure needed by speed reduction according to the vehicle speed and send a speed reduction instruction and the braking pressure to the EBS controller, and the EBS controller can control the EBS proportional relay electromagnetic valve to generate the braking pressure; meanwhile, the EBS proportional relay solenoid valve can feed back the pressure of an air outlet of the EBS proportional relay solenoid valve to the EBS controller so that the EBS controller can adjust the brake pressure conveniently, the EBS proportional relay solenoid valve controls the ABS adjuster through the brake pressure to achieve service brake, automatic drive-by-wire brake of the vehicle is achieved, an original brake system of the vehicle does not need to be damaged, and the service life of the vehicle is prolonged. The structure is simple, and the cost is low.
本发明公开了一种自动驾驶线控制动系统。本发明的车辆处于自动驾驶模式时,若需要减速,整车控制器会根据车速确定减速所需的制动压力,向EBS控制器发送减速指令及制动压力,EBS控制器会控制EBS比例继动电磁阀产生制动压力,同时EBS比例继动电磁阀会向EBS控制器反馈自身出气口压力以便于EBS控制器调节制动压力,EBS比例继动电磁阀进而通过制动压力控制ABS调节器实现行车制动,实现了车辆的自动驾驶线控制动,且无需破坏车辆原有的制动系统,易于实现、结构简单、成本低。
