The invention provides a self-vehicle driving risk quantification method and system considering collision between a self-vehicle and another vehicle. The method comprises the following steps: acquiring vehicle data of the self-vehicle and another vehicle on a driving road where the self-vehicle is located; obtaining a transverse collision urgency coefficient and a longitudinal collision urgency coefficient of the vehicle and the other vehicle based on the vehicle data; on the basis of the transverse collision urgency coefficient and the longitudinal collision urgency coefficient, obtaining the transverse and longitudinal collision urgency degree of the own vehicle from the other vehicle through a piecewise function; and on the basis of the collision severity degree and the collision urgency degree of the own vehicle and the other vehicle, obtaining a driving risk quantification equation representing the driving risk of the own vehicle. According to the self-vehicle driving risk quantification method, the collision problem of the self-vehicle and the other vehicle is comprehensively considered, meanwhile, the influence of transverse collision and longitudinal collision on the driving risk is considered, the self-vehicle driving risk can be accurately quantified, a decision basis is provided for a driving strategy to be executed by the vehicle, and driving safety is guaranteed.
本发明提供一种考虑自车与他车碰撞的自车行车风险量化方法及系统,方法包括:获取自车和自车所在行驶道路上的他车的车辆数据;基于车辆数据,获取自车与他车的横向碰撞紧迫系数和纵向碰撞紧迫系数;基于横向碰撞紧迫系数和纵向碰撞紧迫系数,通过分段函数,得到自车受到的来自他车横向和纵向的碰撞紧迫程度;基于自车与他车的碰撞严重程度和所述碰撞紧迫程度,得到表征自车行车风险的行车风险量化方程。本发明自车行车风险量化方法全方位考虑自车与他车的碰撞问题,同时考虑横向碰撞和纵向碰撞对行车风险的影响,能准确量化自车行车风险,为车辆将要执行的驾驶策略提供决策依据,有利于保障行车安全。
