The invention relates to the technical field of vehicles, in particular to a braking energy recovery method and device, a vehicle and a storage medium. The method comprises the steps that the axle load transfer amount of a front axle and an axle load transfer amount of a rear axle during vehicle braking are obtained; according to the axle load transfer amounts of the front axle and the rear axle, brake torques required by the front axle and the rear axle are calculated; and a driving shaft and a non-driving shaft in the front shaft and the rear shaft are recognized, a corresponding braking mechanism is controlled to conduct hydraulic braking according to the braking torque needed by the non-driving shaft, and a motor is controlled to conduct regenerative braking and energy recovery according to the braking torque needed by the driving shaft. Therefore, the problems of poor riding comfort and the like caused by unreasonable distribution of the braking force of the front shaft and the rear shaft when the braking energy is recovered are solved.
本申请涉及车辆技术领域,特别涉及一种制动能量回收方法、装置、车辆及存储介质,其中,方法包括:获取车辆制动时前后轴的轴荷转移量;根据前后轴的轴荷转移量计算前后轴各自所需的制动力矩;识别前后轴中的驱动轴和非驱动轴,根据非驱动轴所需的制动力矩控制对应的制动机构进行液压制动,并根据驱动轴所需的制动力矩控制电机进行再生制动和能量回收。由此,解决了制动能量回收时前后轴制动力分配不合理,导致乘坐舒适性较差等问题。
