The invention provides a vehicle operation risk real-time assessment method based on a risk field, and the method comprises the steps: collecting the surrounding environment information of a target vehicle through various devices, and dividing a driving environment into three parts: a static traffic environment, dynamic traffic control, and surrounding moving objects. In combination with a risk field theory, calculating risks caused by static traffic environment factors and dynamic traffic control on the target vehicle; according to the method, the collision time is calculated to divide the approaching risk and the collision risk, the approaching risk and the collision risk caused by the moving object to the target vehicle are calculated, finally, all the risks are overlapped, a risk set faced by the target vehicle at the current moment is obtained, and a reliable basis is provided for subsequent safety early warning and driving assistance decision making.
本发明提出了一种基于风险场的车辆运行风险实时评估方法,通过各种设备采集目标车辆周围的环境信息,然后将行车环境分为静态交通环境,动态交通管控,周围运动物体三部分,结合风险场理论计算静态交通环境因素、动态交通管控对目标车辆造成的风险;通过计算冲突时间划分迫近风险和碰撞风险,计算运动物体对目标车辆造成的迫近风险和碰撞风险,最后将风险全部进行叠加,得到目标车辆当前时刻所面临的风险集合,为后续的安全预警和协助驾驶决策提供可靠依据。
