The invention discloses an anti-rollover control method for an automatic driving vehicle, and the method comprises the following steps: S1, constructing a transverse load transfer rate threshold value by taking a transverse load transfer rate as a vehicle rollover definition index; S2, in the running process of the vehicle, when the absolute value of the actual transverse load transfer rate is smaller than the transverse load transfer rate threshold value, determining that the vehicle runs normally; when the absolute value of the actual transverse load transfer rate is greater than the transverse load transfer rate threshold value, selecting the front outer side wheel and the rear inner side wheel relative to the steering direction as braking wheels, when the vehicle steers too much, applying the braking to the front outer side wheel, and when the vehicle steers insufficient, applying braking to the rear inner side wheel. The turning stability of the vehicle can be effectively improved, rollover of the vehicle is reduced, and a good control effect is achieved.
本发明公开了一种自动驾驶的车辆防侧翻控制方法,包括以下步骤:S1、以横向载荷转移率作为车辆侧翻定义指数,构建横向载荷转移率阈值;S2、在车辆行驶过程中,当实际的横向载荷转移率的绝对值小于横向载荷转移率阈值时,正常行驶;当实际的横向载荷转移率的绝对值大于横向载荷转移率阈值时,选择相对于转向方向的前外侧车轮和后内侧车轮作为制动车轮,当车辆转向过多时,对前外侧车轮施加制动,当车辆转向不足时对后内侧车轮施加制动。本发明可以有效改善车辆的转弯稳定性,减少车辆侧翻的发生,具有良好的控制效果。
