The invention discloses an electric vehicle control method for tire burst stable control, a vehicle controller and an electric vehicle, relates to the field of new energy automobiles, and can be applied to pure electric vehicles and hybrid vehicles. The control method is used for controlling the electric vehicle when one wheel bursts in the running process that the speed of the electric vehicle is larger than the preset speed. The control method comprises the steps that at the first moment after tire burst of one wheel of the electric vehicle occurs, the driving torque of the wheel is controlled to be reduced, and the braking force output by the braking system of the electric vehicle to the wheel is controlled to be reduced. According to the scheme, the torque and the braking force are rapidly adjusted, the driving torque and the braking force are rapidly reset, the lateral force friction limit is fully utilized, sufficient allowance is provided for steering lateral force, direction stability control is facilitated, and the vehicle safety is improved.
一种爆胎稳定控制的电动车辆控制方法、车辆控制器和电动车辆,涉及新能源汽车领域,可应用于纯电动车辆及混动车辆。该控制方法用于在电动车辆的车速大于预设车速的行驶过程中的一个车轮发生爆胎时控制电动车辆。控制方法包括在电动车辆的一个车轮发生爆胎后的第一时刻,控制一个车轮的驱动扭矩降低并控制电动车辆的制动系统向一个车轮输出的制动力降低。根据本申请的方案,快速调整扭矩和制动力,将驱动扭矩和制动力快速清零,充分利用侧向力摩擦极限,为转向侧向力提供充足余量,便于方向稳定性控制,提高了车辆安全性。
