The invention discloses a vehicle and an energy recovery method and an energy recovery device thereof, the vehicle comprises a front axle motor and a rear axle motor, the front axle motor is configured to drive front wheels, the rear axle motor is configured to drive rear wheels, and the method comprises the steps that in the vehicle sliding process, the rear wheels are driven by the front axle motor; acquiring a steering wheel angle, a vehicle speed, a front-rear axle speed difference and a rear axle motor recovery torque; obtaining a stability factor according to the steering wheel angle, the vehicle speed, the front and rear axle speed difference and the rear axle motor recovery torque; and determining the switching time of switching the rear axle motor to the front axle motor according to the stability factor. According to the method, a stable factor is determined based on the steering wheel angle, the vehicle speed, the front and rear axle speed difference and the rear axle motor recovery torque, double-axle recovery is activated through the stable factor, and the switching speed of switching the rear axle motor to the front axle motor is adjusted according to the stable factor, so that the running stability of the vehicle is guaranteed.

    本发明公开了一种车辆及其能量回收方法和能量回收装置,所述车辆包括前轴电机和后轴电机,前轴电机被配置为驱动前轮,后轴电机被配置为驱动后轮,所述方法包括:在车辆滑行过程中,获取方向盘转角、车速、前后轴速度差和后轴电机回收扭矩;根据方向盘转角、车速、前后轴速度差和后轴电机回收扭矩获取稳定性因子;根据稳定性因子确定后轴电机切换为前轴电机的切换时间。该方法基于方向盘转角、车速、前后轴速度差和后轴电机回收扭矩确定稳定因子,通过该稳定因子来激活双轴回收,并根据该稳定因子调整后轴电机切换为前轴电机的切换速率,以保证车辆的运行稳定性。
