The invention relates to an anti-rollover safety mechanism for an active side-tipping vehicle and a control method of the anti-rollover safety mechanism, belongs to the technical field of vehicle chassis, and particularly relates to a driving safety redundancy technology for the active side-tipping vehicle. In the driving process of an active roll vehicle on a curve, if the vehicle is automatically controlled to roll to a limit roll angle, when the vehicle needs to avoid obstacles and enlarge a steering angle or is interfered by adverse factors of road surface conditions such as downhill, centrifugal force is sharply increased, and the vehicle possibly turns towards the outer side of the curve after exceeding a limit value which can be borne by the vehicle; according to the redundant safety measures, after the vehicle works to the limit roll angle and the inner side driving wheel slips, the outer side safety tug pops up, the tug and the outer side wheel make contact with the road surface, the vehicle slides and decelerates, the vehicle is prevented from turning towards the outer side of a curve, the safety of a driver and passengers is protected, and vehicle running safety redundancy is achieved.
本发明涉及一种主动侧倾车辆防侧翻安全机构及其控制方法,属于车辆底盘技术领域,特别涉及主动侧倾车辆行驶安全冗余技术;主动侧倾车辆弯道行驶过程中,如果车辆自动控制侧倾至极限侧倾角后,当车辆需要避障加大转向角、或者受到下坡等路面条件不利因素干扰时,导致离心力急剧变大、超越车辆所能够承受的极限值后,可能造成车辆向弯道外侧翻;冗余安全措施为:车辆工作至极限侧倾角后、且内侧驱动轮打滑时,外侧安全拖轮弹出,由拖轮与外侧车轮接触路面、车辆滑行减速,阻止车辆向弯道外侧翻,保护驾乘人员安全,实现车辆行驶安全冗余。
