The invention provides an automatic traction force control method and system for a hinged dump truck and the hinged dump truck. The method comprises the steps that whether the hinged dump truck slides or not is judged; the sliding rotators comprise the drive axle sliding rotators and the wheel sliding rotators. Monitoring vehicle attitude data of the articulated dump truck; the attitude data comprises a vehicle steering angle, a longitudinal slope and cross slope inclination angle of a vehicle front frame and a cross slope inclination angle of a rear frame; determining whether to start or not according to whether the hinged dump truck slips or not, the vehicle posture, a switch key signal, the engine rotating speed and driver operation, and keeping and relieving distribution control of traction force; and the distribution control of the traction force is executed by controlling a braking proportional electromagnetic valve, a power output torque, an engine rotating speed and a differential lock electromagnetic valve group. The differential lock can be automatically locked and released according to the slip condition between the wheels and the drive axle, the traction torque of the vehicle is adjusted, it is ensured that appropriate traction force is applied to all the wheels, and automatic cross-country of the vehicle is achieved.
本发明提供了一种铰接式自卸车的牵引力自动控制方法及系统、铰接式自卸车,该方法包括:判断铰接式自卸车是否发生滑转;所述滑转包括驱动桥滑转和车轮滑转;对铰接式自卸车的车辆姿态数据进行监测;姿态数据包括:车辆转向角度,车辆前车架的纵坡与横坡倾角,后车架的横坡倾角;根据铰接式自卸车是否发生滑转、车辆姿态、开关按键信号、发动机转速及驾驶员操作决定否启用、保持和解除牵引力的分配控制;所述牵引力的分配控制通过控制制动比例电磁阀、动力输出扭矩、发动机转速以及差速锁电磁阀组来执行。本发明能够根据车轮之间和驱动桥之间的滑转情况自动地锁止和释放差速锁,调整车辆牵引扭矩,确保各个车轮上有合适牵引力,实现车辆自动越野。
