The invention provides a protection method and system for small offset collision of a vehicle, and belongs to the technical field of automobiles. The problem that in the prior art, small offset collision cannot be avoided, and a driver and passengers are still greatly hurt is solved. The vehicle small offset collision avoidance method comprises the steps that when an unavoidable collision risk exists between a vehicle and a non-life obstacle in front of the same lane, whether safe driving areas exist on the left side and the right side of the vehicle or not is judged; if the safe driving area exists, the vehicle performs emergency steering according to the planned lane changing path; if the safe driving area does not exist, when it is judged that small offset collision exists between the vehicle and a non-life obstacle in front of the vehicle and a longitudinal beam of the vehicle is located in the collision area, the vehicle executes steering action according to the adjusted driving path so that the collision area of the vehicle can be increased or the collision area of the vehicle can be far away from the longitudinal beam of the vehicle; meanwhile, the vehicle is controlled to conduct emergency braking. The invention can reduce the injury to passengers.
本发明提供了一种车辆小偏置碰撞的保护方法及系统,属于汽车技术领域。它解决了现有的技术无法规避小偏置碰撞,仍会对驾乘人员造成较大伤害的问题。本车辆小偏置碰撞规避方法包括:在自车与同车道前方非生命体障碍物存在无法避免的碰撞风险时,判断自车左右侧是否存在安全行驶区域;若存在安全行驶区域,车辆根据规划的换道路径执行紧急转向;若不存在安全行驶区域,在判断自车与前方非生命体障碍物存在小偏置碰撞且自车的纵梁位于碰撞区域内时,车辆根据调整后的行驶路径执行转向动作,用于增大自车碰撞面积或使自车碰撞区域远离车辆的纵梁,同时控制车辆进行紧急制动。本发明能够减轻乘员伤害。
