The invention discloses an active discharging method of an electric vehicle and the vehicle. The method comprises the following steps: in response to a received active discharging request, obtaining current vehicle state information; if the vehicle state information is a static state, winding discharging is carried out; if the vehicle state information is a motion state, a motor rotating speed value is obtained; and performing winding discharge or discharge resistor discharge based on the motor rotating speed value. Through a specific implementation method of active discharge, the technical problem that in a function safety state, especially an ASC, due to the fact that an upper three-bridge IGBT or a lower three-bridge IGBT is in a conducting state, direct discharge cannot be achieved through a winding or the IGBT is solved.

    本发明公开了一种电动汽车主动放电方法及车辆。该方法可以包括:响应于接收到主动放电请求,获取当前的车辆状态信息;若所述车辆状态信息为静止状态,则进行绕组放电;若所述车辆状态信息为运动状态,则获取电机转速值;基于所述电机转速值,进行所述绕组放电或放电电阻放电。本发明通过一种主动放电的具体实施方法,解决了在功能安全状态下,特别是ASC时,由于上三桥或下三桥IGBT处于导通状态,则通过绕组或者IGBT直通放电则无法实现的需求的技术问题。
