The invention discloses a zero-rotation-speed control method for an automobile electric drive system. The method comprises a static zero-rotation-speed function control strategy used for achieving a whole automobile ramp auxiliary function and an AutoHold function, and the static zero-rotation-speed function control strategy comprises the following steps that 1, whether entering conditions are metor not is judged; and 2, after the entering condition is met, the static zero-rotating-speed function control step is executed, and the whole vehicle is controlled; wherein the entering conditions comprises a response to a VCU request entry condition and an MCU autonomous entry condition and are used for realizing passive entry and autonomous entry of a static zero-rotation-speed function. The method has the advantages that the static and dynamic zero-rotating-speed functions of the vehicle are started and controlled more reliably and reasonably, so that the auxiliary system function of the whole vehicle is safer and more guaranteed, and the auxiliary safety coefficient of the whole vehicle is increased.

    本发明公开了一种汽车电驱系统零转速控制方法,包括用于实现整车坡道辅助功能和AutoHold功能的静态零转速功能控制策略,所述静态零转速功能控制策略包括如下步骤:步骤1:判断进入条件是否满足;步骤2:在满足进入条件后,进入静态零转速功能控制步骤,对整车进行控制;其中判断进入条件包括响应VCU请求进入条件、MCU自主进入条件,用于实现被动进入和自主进入静态零转速功能。本发明的优点在于:本方法更加可靠、合理的实现车辆的静态、动态零转速功能的启动和控制,使得整车的辅助系统功能更加安全有保障,提升整车的辅助安全系数。
