The invention relates to an anti-slip control method which comprises the following steps: 1) judging whether to start an anti-slip function or not according to working parameters of a driving motor and the advancing direction of an automobile; 2) starting an anti-slip function, and judging whether to enter an anti-slip state according to the working state of a driving motor; and 3) entering the anti-slip state, outputting an anti-slip torque by the driving motor, and determining the magnitude of the anti-slip torque by a rotating speed ring PI regulator when the duration of the anti-slip state is greater than a time threshold value. The anti-slip torque can be quickly generated at the moment when the automobile slips on the ramp, and many hazards caused by the fact that the automobile slips on the ramp are avoided. And by judging whether the anti-sliding function is started or not, false triggering of the anti-sliding state can be effectively avoided. In addition, the rotating speed ring PI regulator can carry out real-time adjustment according to the size and length of the gradient and output an anti-slip torque value, the situation that the whole vehicle shakes in the anti-slip process is avoided, and the driving experience of a driver is improved.
本发明涉及一种防溜车控制方法,包括以下步骤:1)根据驱动电机的工作参数以及汽车的行进方向判断是否开启防溜车功能;2)开启防溜车功能,并根据驱动电机的工作状态判断是否进入防溜车状态:3)进入所述防溜车状态,所述驱动电机输出防溜扭矩,当所述防溜车状态持续时间大于时间阈值时,所述防溜扭矩的大小由转速环PI调节器确定。可以实现汽车在坡道上溜坡的瞬间快速产生防溜扭矩,避免了汽车因溜坡而导致的诸多危害。并且通过是否开启防溜车功能的判定,可有效避免防溜车状态的误触发。此外,转速环PI调节器可以根据坡度的大小和长度进行实时地调整并输出防溜扭矩值,避免了防溜时整车抖动的情况,提高了驾驶员的驾驶体验。
