The invention discloses a novel electric vehicle hill-holding strategy, and belongs to the technical field of automatic control. According to the novel electric vehicle hill-holding strategy, following two functions of hill-holding mode judgment and rotating speed ring overshoot reduction are achieved, the situation that a vehicle enters the hill-holding mode is judged in the form of a state machine, the situation that the vehicle enters the hill-holding mode mistakenly due to interference, uneven road surfaces and the like is avoided, the forward movement phenomenon is relieved by adding acceleration differential items, and the influence of noise is effectively avoided.
本发明公开一种新型电动汽车驻坡策略,涉及自动控制技术领域,如下两个功能驻坡模式判定和转速环超调量降低2个功能,通过状态机形式判断车辆在何种情况下,进入驻坡模式,避免了干扰以及路面不平整等情况导致的误进驻坡模式,通过增加加速度微分项,缓解前窜现象,且有效避免噪声的影响。
