The invention discloses an intelligent electric vehicle steering stability control method. The method comprises the following steps: acquiring a current driving road condition; acquiring front road condition information; predicting a safe speed value and a steering angle of turning or headstock turning; automatically adjusting a vehicle speed; and correcting the speed value and the steering angleof the turning or headstock turning, and when a vehicle is driven to enter a to-be-turned lane of the turning or headstock turning, acquiring an inclination state of the current vehicle by a vehicle driving state sensing system, and correcting the speed value and the steering angle. In the invention, the method fully adapts to operation performance of different vehicles and carries out unified reference planning on actual complex and changeable environmental factors; a turning speed value and the steering angle are predicted in advance, and pre-adjustment is performed before turning or turningaround according to a predicted value so that potential safety hazards caused by untimely adjustment or too fast adjustment during turning or turning around are avoided; and meanwhile, real-time adjustment is carried out through callback after the steering angle is excessive and insufficient compensation.
一种智能电动汽车转向稳定控制方法,包括以下步骤:获取当前行驶路况;获取前方路况信息;预测过弯或掉转车头的安全速度值和转向角;车速的自动调节;过弯或掉转车头的速度值和转向角的修正,在驾驶进入过弯或调转车头的待转弯道时,所述车辆行驶状态感知系统获取当前车辆的倾斜状态,对速度值和转向角的修正。本发明充分适应不同车辆的操作性能并将实际的复杂多变的环境因素进行统一参考规划,先通过预先的过弯速度值和转向角的预测,并依据预测值在进入过弯或掉头前进行预先调节,避免过弯或掉头在进行调节的不及时或调节过快带来的安全隐患;同时通过对转向角的过度后的回调以及不足的补偿进行实时调节。
