The invention relates to an anti-rollover control method for high-speed running of an active side-tipping vehicle, belongs to the technical field of vehicle running safety control, adopts a steering intervention technical measure to prevent the vehicle from turning towards the outer side of a curve, and is applied to anti-rollover control for high-speed running of the active side-tipping vehicle and the curve running process of the active side-tipping vehicle. After the vehicle works to the limit roll angle of the vehicle and the lateral angular acceleration of the vehicle is larger than a given threshold value, the steering angle is reduced, the vehicle is prevented from rolling over, then the steering angle is gradually increased, the driving direction of the vehicle is corrected, and safe curve driving of the active roll vehicle is recovered; steering intervention is adopted to achieve high efficiency and quick response to prevent rollover of the vehicle, the stability of the vehicle under the limit working condition is improved, and the limit driving area of the active rollover vehicle is widened.
本发明涉及一种主动侧倾车辆高速行驶防侧翻控制方法,属于车辆行驶安全性控制技术领域,采用转向干预技术措施、阻止车辆向弯道外侧翻,应用于主动侧倾车辆高速行驶防侧翻控制,主动侧倾车辆弯道行驶过程中,工作至车辆极限侧倾角后、且车辆侧向角加速度大于给定阈值时,减小转向角、阻止车辆侧翻,然后逐步增大转向角、校正车辆行驶方向,恢复主动侧倾车辆弯道安全行驶;采用转向干预达到高效率和快速响应阻止车辆侧翻,提高了车辆在极限工况下的稳定性,拓宽主动侧倾车辆的极限行驶区域。
