The invention discloses a driving anti-skid control method and system and an independent four-wheel-drive electric automobile, and the driving anti-skid control method comprises the steps that when the electric automobile deviates from a preset steering track in the steering process and has slipping wheels, the slipping wheels are controlled to reduce the torque until the electric automobile recovers to the preset steering track. According to the driving anti-skid control method, lateral control in the vehicle steering process is further considered, through recognition of the vehicle steering state, when the electric vehicle deviates from the preset steering track and the slipping wheels exist, torque reduction is conducted on the slipping wheels till the electric vehicle recovers to the preset steering track, and therefore the driving anti-skid control method is suitable for the electric vehicle. Neutral steering of the vehicle is maintained in the steering process, the steering tracking capacity of the vehicle is enhanced, and meanwhile the driving anti-skid capacity of the independent four-wheel-drive electric vehicle is improved.
本发明公开了一种驱动防滑控制方法及其系统、独立四驱电动汽车,该驱动防滑控制方法包括:当所述电动汽车在转向过程中偏离预设转向轨迹且存在打滑的车轮时,控制所述打滑的车轮降扭,直到所述电动汽车恢复所述预设转向轨迹。本申请示出的驱动防滑控制方法还考虑了车辆转向过程中的侧向控制,通过对车辆转向状态的识别,在电动汽车偏离预设转向轨迹且存在打滑的车轮时,对打滑的车轮降扭,直到电动汽车恢复到预设转向轨迹为止,使车辆在转向过程中维持中性转向,增强车辆的转向循迹能力,同时提升独立四驱电动汽车的驱动防滑能力。
