An automatic parking system of a high-horsepower CVT tractor comprises an electromagnetic valve A and a mechanical valve B. A hand brake switch is connected with the mechanical valve B. A brake pad isconnected with a piston and connected with the mechanical valve B through the electromagnetic valve A to form a control loop. When the vehicle runs normally, the piston is jacked up by charging oil,and the vehicle is not braked; when the whole vehicle TCU judges that automatic parking is needed, the electromagnetic valve A performs switching action, the piston is pressed down to discharge oil, and the vehicle is braked; when a driver judges that parking is needed, the mechanical valve B is controlled through the hand brake switch to conduct switching action, the piston is pressed down to discharge oil, and the vehicle is braked. Pressure sensors are respectively arranged on pipelines at the output ends of the electromagnetic valve A and the mechanical valve B, and real-time monitoring iscarried out by comparing numerical values of the two sensors. The driving experience of a driver is improved, the driving habit of a passenger vehicle is met, the vehicle cannot be controlled to lag,and the method is suitable for uphill and downhill of a high-horsepower CVT tractor and frequent starting and stopping.

    一种大马力CVT拖拉机自动驻车系统,包括电磁阀A和机械阀B,手刹开关与机械阀B相连,刹车片连接活塞,通过电磁阀A和机械阀B连接组成控制回路;车辆正常行驶时活塞充油顶起,车辆不进行制动;当整车TCU判断需要自动驻车时,电磁阀A进行切换动作,活塞压下将油排出,车辆进行制动;当驾驶员判断需要驻车时,通过手刹开关控制机械阀B,机械阀B进行切换动作,活塞压下将油排出,车辆进行制动。电磁阀A与机械阀B的输出端管路上分别设有一个压力传感器,通过对比两个传感器的数值进行实时监控。本发明改善了驾驶员对驾驶的体验,贴合乘用车的驾驶习惯,使车辆不会控制滞后,适用于大马力CVT拖拉机上下坡以及频繁起步停车时。
