The invention relates to an active anti-slip method for an electric vehicle based on a multi-phase motor, comprising a multi-phase motor system, when the vehicle enters an active anti-slip mode, firstly outputting the maximum locked-rotor torque to maintain the vehicle static, then monitoring whether the vehicle speed is reverse, judging the road condition, and utilizing the multi-mode locked-rotor of the multi-phase motor system to realize the active anti-slip mode. According to the active anti-slope-sliding method for the electric vehicle, which is formulated in combination with an ASC mode, adaptive strategies can be made according to different slope working conditions, so that the overheating risk of a motor winding, a motor controller, a power device and the like and the slope-sliding risk of the vehicle are effectively avoided.
本发明涉及一种基于多相电机的电动汽车用主动防溜坡方法,包括多相电机系统,当车辆进入主动防溜坡模式时,先输出最大堵转扭矩维持车辆静止,随后监测车速是否倒退转速,判定路况,并利用多相电机系统的多模式堵转,并结合ASC模式制定的电动汽车主动防溜坡方法,可以针对不同坡度工况做出适应性策略,从而进行有效的规避电机绕组、电机控制器、功率器等过热风险以及车辆的溜坡风险。
