The invention provides an anti-slip control method and system of a vehicle, the anti-slip control method and system are applied to the anti-slip control system, the anti-slip control system comprises a motor controller, a rotating speed regulator and an anti-slip feed-forward module, and the method comprises the steps that when it is determined that the anti-slip state of the current vehicle is activated, the anti-slip feed-forward module is triggered to be started; determining a first anti-slip feed-forward value and a first anti-slip feed-forward rate based on the target type of the vehicle; determining a target anti-slip feed-forward value according to the first anti-slip feed-forward rate and the first anti-slip feed-forward value; and determining output torque based on the target anti-slope-sliding feed-forward value and the rotating speed output by the rotating speed regulator, and outputting the output torque through a motor to control the vehicle to run according to the driving instruction. According to the scheme, the anti-slope-sliding feedforward module and the rotating speed regulator are used in a combined mode so that self-adaptive control over different whole vehicle masses and different slopes can be achieved, and therefore motor control failure is avoided.
本发明提供一种车辆的防溜坡控制方法及系统,应用于防溜坡控制系统,防溜坡控制系统包括电机控制器、转速调节器和防溜坡前馈模块,该方法包括:在确定当前车辆的防溜坡状态被激活时,触发防溜坡前馈模块启动;基于车辆的目标类型确定第一防溜坡前馈值和第一防溜坡前馈速率;依据第一防溜坡前馈速率和第一防溜坡前馈值确定目标防溜坡前馈值;基于目标防溜坡前馈值和转速调节器输出的转速,确定输出扭矩,并将输出扭矩通过电机输出,以控制车辆按驾驶指令运行。该方案中,将所提出的防溜坡前馈模块与转速调节器组合使用,以实现不同整车质量和不同坡度的自适应控制,从而避免电机控制失效。
