The invention relates to the technical field of vehicle running stability control, and discloses a vehicle active roll control method which adopts the technical measures: setting a variable torque coefficient K, and changing the driving torque of a steering inner side driving wheel according to the vehicle steering angle correction delta(theta); in the vehicle running process, calculating the torque correction delta(T) through the variable torque coefficient delta(K) and the vehicle steering angle correction delta(theta), increasing the torque of a steering inner side driving wheel by delta(T), and forming a certain driving torque difference on the left side and the right side, so that the vehicle presents a reverse steering trend before steering running, a reverse centrifugal force is provided, and a part of torque is provided for the active roll movement of the vehicle, so that the power required for driving the vehicle to roll is reduced, and the occupied space, weight and cost of the vehicle roll driving module can be reduced.
本发明涉及车辆行驶稳定性控制技术领域,公开了一种车辆主动侧倾控制方法,所采用的技术措施为:设置一个变力矩系数K,依据车辆转向角修正量△θ改变转向内侧驱动轮的驱动扭矩;车辆行驶过程中,通过变力矩系数K和车辆转向角修正量△θ计算出力矩修正量△T,将转向内侧驱动轮的扭矩提高△T,左右两侧形成一定驱动力矩差使车辆在转向行驶之前呈现出反向转向的趋势,以提供反向离心力,为车辆的主动侧倾运动提供部分力矩,从而降低驱动车辆侧倾所需要的功率,可以减少车辆侧倾驱动模块所占用的空间、重量和成本。
