The invention discloses a control method for reducing turning roll, a vehicle controller and an electric vehicle, relates to the field of new energy vehicles, and can be applied to pure electric vehicles and hybrid vehicles. The control method comprises the steps that the steering wheel angle of the electric vehicle is increased from zero at the first moment, the torque output by an active transverse stabilizer bar of the electric vehicle is controlled to be increased, and the difference value of the driving torque of a left wheel and the driving torque of a right wheel which are coaxial of the electric vehicle is controlled to be increased. And at a second moment after the first moment, the steering angle of the steering wheel of the electric vehicle is increased from being smaller than the preset steering angle to being equal to or larger than the preset steering angle, the torque output by the active transverse stabilizer bar is controlled to be reduced, and the difference value of the driving torque of the left wheel and the driving torque of the right wheel is controlled to be reduced. According to the scheme, the roll angle of the vehicle body in the turning process can be reduced, the vehicle body control capacity is improved, the system robustness is improved, and the driving experience and safety of the vehicle are improved.

    一种降低转弯侧倾的控制方法,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。控制方法包括在第一时刻电动车辆的方向盘转角从零增大,控制电动车辆的主动横向稳定杆输出的扭矩增大并控制电动车辆的同轴的一个左侧车轮的驱动扭矩和一个右侧车轮的驱动扭矩的差值增大。在第一时刻之后的第二时刻,电动车辆的方向盘转角从小于预设转角增大至等于或大于预设转角,控制主动横向稳定杆输出的扭矩减小并控制一个左侧车轮的驱动扭矩和一个右侧车轮的驱动扭矩的差值减小。根据本申请的方案,可以降低转弯过程中车身的侧倾角,提升车身控制能力,提升了系统鲁棒性,提高车辆的驾驶体验和安全性。
