The invention relates to the technical field of electric automobiles, in particular to a brake energy recovery control method for an extended-range electric automobile, which comprises the following specific steps: 1, a driver steps on a brake pedal, brake energy recovery control is performed, and data is transmitted to a sensing module; 2, the sensing module detects the depth of a driver stepping on a brake pedal and transmits the depth to the decision module; 3, the decision-making module is responsible for analyzing, judging and deciding, deciding the magnitude of the braking demand torque, and providing input for the execution module at the rear end; and 4, the execution module is responsible for carrying out target braking torque closed-loop control according to the decided braking demand torque value input by the decision-making module, and the problem that mechanical braking can only judge that a driver has a braking intention through a brake switch; and then a fixed braking torque and an electric braking and mechanical braking conversion gap are requested, so that the whole vehicle is more easily unstable or even out of control under extreme working conditions, the driving experience of the whole vehicle is seriously reduced, and even the driving safety is threatened.

    本发明本发明涉及电动汽车技术领域,具体地说,本发明涉及一种增程式电动汽车制动能量回收控制方法,具体步骤如下:1、驾驶员踩下制动踏板,制动能量回收控制,并将数据传输给感知模块;2、感知模块探测驾驶员踩下制动踏板的深度,传递给决策模块;3、决策模块负责进行分析判断和裁决,决策制动需求扭矩的大小,为后端的执行模块提供输入;4、执行模块负责根据决策模块输入的裁决后的制动需求扭矩值进行目标制动扭矩闭环控制,解决机械制动只能通过刹车开关判断驾驶员有制动意图,然后请求固定不变的的制动扭矩以及电制动和机械制动转换间隙对于极端工况将更容易导致整车失稳甚至失控,严重降低整车驾驶体验甚至威胁驾乘安全的问题。
