The invention discloses a torque control intervention opportunity calculation method for preventing a vehicle from slipping, which comprises the following steps of: determining slip and a threshold according to the wheel speed of each wheel, the opening degree of an accelerator pedal and the opening degree of a brake pedal; the slip and threshold are corrected according to the obtained wheel acceleration, and a slip and threshold primary correction value is obtained; according to the vehicle sensing parameters, the slip and threshold primary correction value is determined to be corrected again, and a slip and threshold secondary correction value is obtained; determining the slip sum of the driving wheels according to the wheel speed of each wheel; and when the slip sum of the driving wheel is greater than the slip sum threshold secondary correction value, the torque control is intervened. Advanced intervention of the torque control function is achieved, and tire slipping and insufficient/excessive steering can be effectively avoided.

    本发明公开了一种防止车辆打滑的扭矩控制介入时机计算方法,包括:根据各轮的轮速、加速踏板开度、制动踏板开度,确定滑转和门限;根据获取的轮加速度对滑转和门限进行修正,得到滑转和门限一次修正值;根据车辆传感参数,确定对滑转和门限一次修正值再次修正,得到滑转和门限二次修正值;根据各轮的轮速,确定驱动轮滑转和;当驱动轮滑转和大于滑转和门限二次修正值时,使扭矩控制介入。本发明实现了扭矩控制功能的提前介入,能有效避免轮胎滑转、转向不足/过度。
