The invention discloses an active anti-shake control method for an electric vehicle, which comprises the following steps of: acquiring vehicle parameters, determining a target required torque of the vehicle according to the vehicle parameters, and determining whether to control an actual output torque by adopting a tooth-dependent torque mode or not according to the size of the target required torque when the change of a torque direction is detected. The tooth-dependent torque mode is that the actual output torque is a tooth-dependent torque calibration value and is maintained for a set time. According to the method, when the torque direction changes, the actual output torque is determined through calibration of the tooth torque value and the action time, the zero crossing point impact problem can be rapidly solved, the whole vehicle is prevented from shaking, the method is simple and efficient, and the whole vehicle driving experience is greatly improved.
本发明公开了一种电动汽车主动防抖控制方法,采集车辆参数,根据车辆参数确定车辆的目标需求扭矩,当检测到扭矩方向发生变化时,根据目标需求扭矩的大小确定是否采用靠齿扭矩模式控制实际输出扭矩,所述靠齿扭矩模式为:实际输出扭矩大小为靠齿扭矩标定值并维持设定时间。本发明在扭矩方向变化时通过靠齿扭矩值大小和作用时间的标定确定实际输出扭矩,能快速解决过零点冲击问题,从而防止整车抖动,方法简单、高效,极大提升了整车驾驶体验性。
