The invention discloses a regenerative braking control method for an electric vehicle, which comprises the following steps: acquiring information of required braking force, judging whether the current running speed of the electric vehicle is smaller than a preset first speed or not, and if the current running speed of the electric vehicle is smaller than the preset first speed, executing mechanical braking; if the current running speed of the electric automobile is larger than a preset first speed, whether the current braking strength is larger than a set first threshold value or not is judged, and if the current braking strength is larger than the set first threshold value, mechanical braking is executed; if the current braking strength is smaller than a set first threshold value, whether the current battery SOC is larger than an SOC critical value or not is judged, and if the current battery SOC is larger than the SOC critical value, mechanical braking is executed; and if the SOC is smaller than the SOC critical value, the motor and the machine execute combined braking. Compared with the prior art, the method has the beneficial effects that automobile brake control is more accurate, the energy consumption of the electric automobile can be effectively reduced, and the driving range is increased.

    本发明公开了一种电动汽车再生制动控制方法,获得需要制动力的信息,判断当前电动汽车的运行速度是否小于预设的第一速度,若当前电动汽车的运行速度小于预设的第一速度,执行机械制动;若当前电动汽车的运行速度大于预设的第一速度,则判断当前制动强度是否大于设定的第一阈值,若当前制动强度大于设定的第一阈值,则执行机械制动;若当前制动强度小于设定的第一阈值,则判断当前电池SOC是否大于SOC临界值,若当前电池SOC大于SOC临界值,则执行机械制动;若小于SOC临界值,则电机与机械执行联合制动。与现有技术相比,有益效果在于:使得汽车制动控制更加精准,能够有效降低电动汽车的能量消耗,提升续驶里程。
