The invention provides a vehicle collision brake control system which can reduce continuous damage caused by vehicle collision. The control system comprises a sensor and a controller, the sensor is a safety contact edge, and the vehicle is in a hydraulic braking mode; after the safety contact edge is triggered, the controller sends an electric signal to the relay, the relay supplies power to the braking electromagnetic valve after being conducted, the braking electromagnetic valve supplies hydraulic oil to a vehicle braking system after being attracted, and a vehicle brakes. The system further comprises an unlocking switch, the unlocking switch is pressed down in a neutral gear state, the unlocking switch sends an electric signal to the controller after being connected, the controller checks whether the vehicle safety contact edge is in a triggered state or not, and unlocking operation is carried out if the vehicle safety contact edge is not triggered. If not, gear judgment is carried out, whether the current gear of the vehicle is opposite to the gear triggered by the touch edge or not is judged, unlocking is carried out if the current gear is opposite to the gear, and otherwise, unlocking is not carried out. According to the unlocking process, various conditions are fully considered, and the operation safety of the whole system is ensured.
提供一种车辆碰撞制动控制系统,降低车辆碰撞造成的持续性损害。所述的控制系统包括传感器、控制器,所述传感器为安全触边,车辆为液压制动;安全触边触发后,控制器发送电信号至继电器,继电器导通后为制动电磁阀供电,制动电磁阀吸合后向车辆制动系统供液压油,车辆制动。所述系统还包括解锁开关,空挡状态下按下解锁开关,解锁开关接通后发送电信号至控制器,控制器检查车辆安全触边是否为触发状态,未触发则进行解锁操作;反之则进行档位判断,判断车辆当前档位是否与触边触发时的档位反向,反向则解锁,反之则不解锁。该解锁流程充分考虑了各种情况,保证了整个系统运行的安全性。
