The invention discloses a control method and system for new energy automobile braking energy recovery, and relates to the technical field of intelligent new energy automobiles. Judging whether the vehicle is in a wriggling state or not, and if yes, not entering the energy recovery state; if not, whether the opening degree of the accelerator pedal is zero or not is detected, if not, the energy recovery state is not entered, and if yes, the energy recovery state is entered, and a brake lamp is lightened; when the steering wheel enters the energy recovery state, an energy recovery mode is switched through a braking energy recovery key on the steering wheel; when the energy recovery mode is the automatic mode, the energy recovery intensity is automatically switched according to the pitching angle of the vehicle; and when the energy recovery mode is the manual mode, manually switching the energy recovery intensity. The energy recovery intensity can be automatically adjusted according to the uphill and downhill states of the automobile, the brake lamp is lightened while energy recovery work is braked, and the problem that a driver of a rear automobile cannot be reminded in time to decelerate to cause rear-end collision of the automobile is solved.

    本发明公开一种新能源汽车制动能量回收的控制方法及系统,涉及智能新能源汽车技术领域,包括:获取车辆的行驶状态信息;判断车辆是否处于蠕动状态,若是,不进入能量回收状态;若否,检测油门踏板开度是否为零,若否,不进入能量回收状态,若是,进入能量回收状态,点亮刹车灯;当进入能量回收状态时,通过方向盘上的制动能量回收按键切换能量回收的模式;当能量回收模式为自动模式时,根据车辆俯仰角度自动切换能量回收的强度;当能量回收模式为手动模式时,手动切换能量回收的强度。本发明可以根据汽车上下坡的状态自动调节能量回收的强度,在制动能量回收工作的同时点亮刹车灯,避免了不能及时提醒后车驾驶员减速行驶导致汽车被追尾的问题。
