The invention relates to the technical field of vehicle control, in particular to a retarding braking control method and system for an electric vehicle. The method comprises the steps that S11, based on vehicle starting, set data are obtained; step S12, acquiring first driving energy consumption Q1 on the basis that the vehicle runs from the travel starting point to the judgment point; step S13, acquiring second driving energy consumption Q2 on the basis of the first driving energy consumption Q1; and step S14, based on Q1 + Q2 < A, starting the consumption mode. Therefore, the problem that mechanical braking intervention is reduced when the electric vehicle goes downhill is solved.

    本发明涉及车辆控制技术领域,具体而言,涉及一种电动车辆缓速制动控制方法及系统。方法包括步骤S11,基于车辆启动,获取设定数据;步骤S12,基于所述车辆从所述行程起点行驶至所述判断点,获取第一行驶能耗Q1步骤S13,基于所述第一行驶能耗Q1,获取第二行驶能耗Q2;步骤S14,基于Q1+Q2<A,开启所述消耗模式。这样就解决了电动车辆下坡时减少机械制动介入的问题。
