The invention discloses a traction auxiliary control system and method for a mining mechanical transmission dump truck. The control system comprises a traction auxiliary controller, a left front wheelangular velocity sensor, a right front wheel angular velocity sensor, a left rear wheel angular velocity sensor, a right rear wheel angular velocity sensor, an engine ECU, a left rear wheel electro-hydraulic proportional valve, a right rear wheel electro-hydraulic proportional valve, a left rear wheel brake and a right rear wheel brake. The traction auxiliary controller is used for collecting signals of angular velocity sensors on four wheels to control an engine ECU, the left rear wheel electro-hydraulic proportional valve and the right rear wheel electro-hydraulic proportional valve; the left rear wheel brake is controlled through the left rear wheel electro-hydraulic proportional valve, and the right rear wheel control brake is controlled through the right rear wheel electro-hydraulicproportional valve and a right full wheel electro-hydraulic proportional valve. The control system and the control method can effectively improve the operation stability of a vehicle when the vehicleslips.
本发明公开了一种矿用机械传动自卸车牵引辅助控制系统及控制方法,控制系统包括牵引辅助控制器、左前车轮角速度传感器、右前车轮角速度传感器、左后车轮角速度传感器、右后车轮角速度传感器、发动机ECU、左后车轮电液比例阀、右后车轮电液比例阀、左后车轮制动器、右后车轮制动器。其中牵引辅助控制器用于采集四个车轮上角速度传感器的信号;控制发动机ECU;控制左后车轮电液比例阀、右后轮电液比例阀,并通过左后轮电液比例阀对左后轮制动器进行控制及通过右后轮电液比例阀对右全车轮电液比例阀对右后车轮控制动器进行控制。本控制系统和控制方法可以在车辆打滑时有效提高其运行稳定性。
