The invention discloses an emergency risk avoiding method and system for a vehicle, the vehicle and equipment. The urgent danger avoiding method for the vehicle comprises the steps that whether the time when the vehicle collides with a front vehicle reaches urgent danger avoiding threshold time or not is judged, and the urgent danger avoiding threshold time is determined according to the collision time TTC; if yes, the current vehicle speed and load are obtained, and the corresponding maximum steering wheel angle is obtained from a pre-stored maximum steering wheel angle table according to the current vehicle speed and load; performing path planning of emergency lane changing to obtain a risk avoiding path; and according to the risk avoiding path, electric power steering control and anti-lock braking control are carried out. By the adoption of the method and device, the initiative of emergency danger avoiding and the predictability of danger can be improved, collision or rollover accidents caused by misoperation of a driver are reduced or even avoided, especially in the high-speed driving process, the safety and reliability of the vehicle when the vehicle deals with emergencies are effectively improved, and the safety of the vehicle is improved. And the safety performance of the vehicle is effectively improved.
本申请公开了一种车辆的紧急避险方法、系统、车辆及设备。车辆的紧急避险方法,包括:判断车辆与前车发生碰撞的时间是否达到紧急避险门限时间,紧急避险门限时间是根据碰撞时间TTC确定的;如果是,则获得当前的车辆速度和载重,并根据当前的车辆速度和载重从预存的最大方向盘转角表中得到相应的最大方向盘转角;进行紧急变道的路径规划,得到避险路径;根据避险路径,进行电动助力转向控制以及防抱死制动控制。采用本申请,可以增加紧急避险的主动性以及危险的预见性,降低甚至避免因驾驶员的操作不当而导致的碰撞或者侧翻事故,尤其在高速行驶过程中,有效地提升了车辆应对突发情况时的安全性和可靠性,使得车辆的安全性能得到有效的提升。
