The invention relates to a whole vehicle braking energy recovery control method and device, equipment and a storage medium. The method comprises the steps that a whole vehicle state signal is obtained; whether energy recovery is triggered or not is judged according to the whole vehicle state signal; under the condition that energy recovery is triggered, the braking torque of the motor is determined; determining a hydraulic brake pressure and an additional brake pressure based on the brake pedal opening and the vehicle speed; according to the working state of the motor, whether the additional braking pressure and the hydraulic braking pressure are output in a superposed mode or not is judged, and the working state of the motor comprises a feedback torque limited state triggered when the deviation between the actual torque of the motor and the braking torque of the motor exceeds a preset condition.
本发明涉及一种整车制动能量回收控制方法、装置、设备及存储介质,该方法包括:获取整车状态信号;根据所述整车状态信号判断是否触发能量回收;在触发能量回收的情况下,确定电机制动扭矩;基于制动踏板开度和车速确定液压制动压力和额外制动压力;根据电机工作状态,判断是否将所述额外制动压力与所述液压制动压力叠加输出,其中,所述电机工作状态包括当电机实际扭矩与所述电机制动扭矩的偏差超过预设条件时触发的回馈扭矩受限状态。
