The invention provides a braking energy recovery control method and device, a storage medium and a vehicle, and belongs to the technical field of vehicle control. According to the embodiment of the invention, under the condition that a locking mechanism of a hydraulic torque converter is in a locking state and a brake pedal treading signal is received, working condition information of the vehicle is obtained, and the braking energy recovery control method and device can be achieved based on the working condition information; determining whether the vehicle meets a braking energy recovery limiting condition or not; and under the condition that the vehicle meets the braking energy recovery limiting condition, the negative torque capacity value of the whole vehicle is adjusted, so that when the locking mechanism meets the opening condition, the target braking energy recovery capacity value can reach the target torque, the negative torque output by the driving motor is effectively prevented from supporting and extinguishing the engine, and the safety of the vehicle is improved. And the braking deceleration of the whole vehicle is prevented from being suddenly reduced, so that the braking performance of the whole vehicle is ensured, and the driving experience of a user is effectively improved.
本申请提供了一种制动能量回收控制方法、装置、存储介质和车辆,属于车辆控制技术领域,本申请实施例通过在液力变矩器的锁止机构为锁止状态且接收到制动踏板踩踏信号的情况下,获取车辆的工况信息,能够基于工况信息,确定车辆是否满足制动能量回收限制条件;并且在车辆满足制动能量回收限制条件的情况下,对整车负扭矩能力值进行调整,使得在锁止机构满足打开条件时,目标制动能量回收能力值能够达到目标扭矩,有效避免驱动电机输出的负扭矩托灭发动机,并防止整车制动减速度突然减小,进而保证整车的制动性,有效改善用户的驾驶体验。
