Abstract

An electric control hydraulic brake system for an unmanned vehicle comprises a brake controller and a brake electromagnetic valve. The brake controller is connected with the control end of the brake electromagnetic valve. The hydraulic brake system further comprises a high definition camera, an ultrasonic wave radar, a millimeter wave radar, an emergency stop switch, a front anti-collision sensor,a rear anti-collision sensor, a load sensor, a vehicle speed sensor, a pressure sensor and an electric hydraulic pump. The signal output ends of the load sensor, the vehicle speed sensor and the pressure sensor are in signal connection with the brake controller. The brake electromagnetic valve comprises a first vehicle traveling brake electromagnetic proportion valve, a second vehicle traveling brake electromagnetic proportion valve and a parking brake electromagnetic reversing valve. The brake controller is in signal connection with the control ends of the first vehicle traveling brake electromagnetic proportion valve, the second vehicle traveling brake electromagnetic proportion valve, the parking brake electromagnetic reversing valve and the hydraulic pump. According to the electric control hydraulic brake system, brake logic multiple judgment reliability of the vehicle is high, the multiple sensors are adopted to be applied into a certain range in a combined mode to achieve non-blind-area detection, and the brake response speed is high.

Description

technical field [0001] The invention relates to an electronically controlled hydraulic braking system of an unmanned vehicle and a control method thereof, and is particularly suitable for improving the driving safety of the unmanned vehicle. Background technique [0002] At present, the hydraulic braking system of unmanned vehicles is mainly realized by the active booster module. When the vehicle needs to brake, the electric signal control module starts to build pressure, and when the pressure reaches a certain value, the required braking effect is achieved. However, since this method builds pressure from normal pressure when the vehicle needs to brake, the disadvantage of slow braking response is very obvious, and is limited by the volume of the booster module, and the maximum brake pressure that the booster module can produce The oil pressure is also relatively small, which often cannot meet the braking requirements of large-tonnage unmanned vehicles. [0003] In terms of...
