The invention provides an electric vehicle turning control method, a vehicle controller and an electric vehicle, and is applied to the technical field of electric vehicles. The control method is used for controlling a braking system and a driving system of the electric vehicle to reduce the turning radius of the electric vehicle in the turning process of the electric vehicle. The control method comprises the steps that at the first moment, the right turning angle of a steering wheel of the electric vehicle is increased from zero, and two front wheels of the electric vehicle are controlled to turn right; at a second moment after the first moment, the rightward turning angle of the steering wheel of the electric vehicle is increased to be larger than a first preset angle, and in the process that the driving system is controlled to output driving torque to the electric vehicle so as to drive the electric vehicle to run, a braking system of the electric vehicle is controlled to output braking force to two right wheels of the electric vehicle. On the basis, coordinated control over the driving system and the braking system is achieved, the turning radius of the electric vehicle can be reduced, and the driving direction can be rapidly changed in the turning process.

    本申请提供了一种电动车辆转弯的控制方法、车辆控制器和电动车辆,应用于电动汽车技术领域。其中,控制方法用于在电动车辆转弯过程中控制电动车辆的制动系统和驱动系统减小电动车辆的转弯半径。以及控制方法包括在第一时刻,电动车辆的方向盘向右转角从零开始增大,控制电动车辆的两个前轮向右转向;在第一时刻之后的第二时刻,电动车辆的方向盘向右的转角增大至大于第一预设角度,在控制驱动系统向电动车辆输出驱动扭矩以驱动电动车辆行驶的过程中,控制电动车辆的制动系统向电动车辆的两个右侧车轮输出制动力。基于此,实现对驱动系统和制动系统的协调控制,能够减小电动车辆的转弯半径和在转弯过程中快速地改变行驶方向。
