The invention discloses a power control method and device of a vehicle, a medium, a vehicle controller and the vehicle. The method comprises the following steps: if a torque vector control function is activated, determining a first torque distribution proportion of each driving wheel according to a dynamic load of each driving wheel of the vehicle; according to the whole vehicle demand torque of the vehicle and the first torque distribution proportion of each driving wheel, the first distribution torque of the corresponding driving wheel is determined; when the corresponding driving wheel is driven according to the first distribution torque of each driving wheel, and the steering angle of the steering wheel of the vehicle is a set angle; the integral area of the mapping curve of the turning radius and the lateral acceleration of the vehicle as the first curve is smaller than the integral area of the mapping curve of the turning radius and the lateral acceleration of the vehicle as the second curve when the torque vector control function is not activated. According to the method, the lateral acceleration interval of stable steering and non-slip of the vehicle is prolonged, and the maximum vehicle speed limit of stable turning is improved.

    本发明公开了一种车辆的动力控制方法、装置、介质、车辆控制器及车辆。该方法包括:若扭矩矢量控制功能激活,根据车辆的每个驱动车轮的动态载荷确定每个驱动车轮的第一扭矩分配比例;根据车辆的整车需求扭矩和每个驱动车轮的第一扭矩分配比例,确定相应的驱动车轮的第一分配扭矩;其中,当根据每个驱动车轮的第一分配扭矩驱动对应的驱动车轮且车辆的方向盘转角为设定角度时,车辆的转弯半径和侧向加速度的映射曲线为第一曲线的积分面积小于扭矩矢量控制功能未激活时车辆的转弯半径和侧向加速度的映射曲线为第二曲线的积分面积。该方法延长了车辆稳定转向不打滑的侧向加速度区间,提高了稳定转弯的最大车速极限。
