Auxiliary risk assessment method and system for vehicle night driving

The invention relates to the related field of driving assistance, and discloses an auxiliary risk assessment method and system for vehicle night driving, and the method comprises the steps: carrying out the environment light and shadow change of an intersection on a passing route during the night driving of a vehicle, and carrying out the simulation assessment of the change superposition amount of the vehicle for the environment light, therefore, after actual light intensity distribution monitoring is carried out on the intersection, the existence condition of the third-party vehicle can be simulated and calculated, the advancing direction of the third-party vehicle is judged according to shadow changes, and intersection vehicle risk early warning of the intersection is provided for a driver at the intersection with the limited visual field, so that the purpose of assisting the driver in safe driving is achieved. 本发明涉及驾驶辅助相关领域，公开了一种车辆夜间行驶的风险辅助评估方法及系统，通过在车辆夜间行驶时，对通行路线上的交叉路口进行环境光影变化，对自身车辆对于环境光照的变化叠加量进行模拟评估，进而可以
