Ramp assisting system and method for wheeled engineering machinery vehicle
The invention discloses a wheel type engineering machinery vehicle ramp assisting system which comprises a tilt angle sensor, a brake pressure sensor, a brake proportional valve, a brake foot valve and a controller. The tilt angle sensor is arranged on a frame of the engineering machinery vehicle and is used for detecting the posture of a vehicle body; the brake pressure sensor is respectively connected with the brake foot valve and the controller; the controller is connected with control ports of the brake proportional valve and the brake foot valve, a pressure output port of the brake proportional valve is connected with a pressure input port in one side of the shuttle valve, a pressure output port of the brake foot valve is connected with a pressure input port in the other side of the shuttle valve, and a pressure output port of the shuttle valve is connected with the brake. And the controller sends a corresponding control signal to the brake proportional valve according to monitoring data of the tilt angle sensor, so that the brake proportional valve outputs brake pressure. And when the vehicle is started on a slope, the controller controls the braking proportional valve according to the treading condition of the braking foot valve, so that the slope sliding condition during hill starting is prevented.
本发明公开了一种轮式工程机械车辆坡道辅助系统，包括：倾角传感器、制动压力传感器、制动比例阀、制动脚踏阀以及控制器；所述倾角传感器设置于工程机械车辆车架上，用以检测车身姿态；所述制动压力传感器分别与制动脚踏阀以及控制器连接；所述控制器分别与制动比例阀以及制动脚踏阀的控制口连接，所述制动比例阀的压力输出口与梭阀一侧的压力输入口连接，制动脚踏阀的压力输出口与梭阀另一侧的压力输入口连接，梭阀的压力输出口与制动器连接；所述控制器根据倾角传感器的监测数据给制动比例阀相应的控制信号使其输出制动压力，本发明通过倾角传感器倾角传感器对车身姿态进行判断，并在车辆坡道起步时通过控制器根据制动脚踏阀的踩踏情况对制动比例阀进行控制防止了坡道起步时溜坡情况的发生。
