The invention discloses a vehicle output torque control method and device and a vehicle, 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 the lateral acceleration of the vehicle is obtained; and determining a torque distribution strategy according to the lateral acceleration, and determining a front axle output torque and a rear axle output torque according to the torque distribution strategy. Therefore, according to the method, the current operation condition of the vehicle is determined based on the obtained lateral acceleration of the vehicle, so that the torque distribution strategy is determined according to the different operation conditions, and the operation stability of the vehicle under the different operation conditions is guaranteed.

    本发明公开了一种车辆输出扭矩的控制方法和控制装置及车辆,其中,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:获取车辆的侧向加速度;根据侧向加速度确定扭矩分配策略,并根据扭矩分配策略确定前轴输出扭矩和后轴输出扭矩。由此,该方法基于获取的车辆的侧向加速度确定当前车辆的运行工况,从而根据不同的运行工况确定扭矩分配策略,以保证车辆在不同运行工况下的运行稳定性。
