The invention provides an electric vehicle braking energy recovery control method. The method comprises the steps that a braking signal of an electric vehicle is monitored and collected in real time;whether the braking signal is an emergency braking signal or not is judged; if so, an electronic braking force distribution system and an anti-lock braking system of the electric vehicle are controlled to brake the electric vehicle according to the driving state of the electric vehicle before the braking signal is input; if not, whether the electric vehicle meets a preset energy recovery conditionor not is judged; and if the preset energy recovery condition is met, one or more of a power assembly, a mechanical braking system, an electronic braking force distribution system and an anti-lock braking system of the electric vehicle are controlled to brake the electric vehicle according to the driving mode of the electric vehicle. According to the scheme, when the energy recovery condition ismet, different braking strategies are selected according to different conditions, and the energy recovery efficiency can be improved.

    本发明提供一种电动车制动能量回收控制方法,包括:实时监测并采集电动车的制动信号;判断制动信号是否为紧急制动信号;若是,则根据制动信号输入前电动车的行驶状态控制电动车的电子制动力分配系统以及制动防抱死系统制动电动车;若否,判断电动车是否符合预设能量回收条件;若符合预设能量回收条件,则根据电动车的驾驶模式控制电动车的动力总成、机械制动系统、电子制动力分配系统、制动防抱死系统中的一个或多个制动电动车。本方案在符合能量回收条件时,根据不同的情况选择不同的制动策略,可以提高能量回收的效率。
