Zusammenfassung:	The invention discloses a vehicle control method and system based on illumination intensity. The method comprises the following steps: acquiring time geographic data of a current driving position of a vehicle; calculating the solar altitude according to the time geographic data; determining a to-be-measured road section based on the driving route, the driving position and the vehicle speed of the vehicle; acquiring tree information and building information of a to-be-measured road section; calculating a shadow area proportion based on the solar altitude, the tree information, the building information and the total road section area of the to-be-measured road section; acquiring the illumination intensity and the atmosphere transparency of the current environment of the vehicle; calculating a light intensity safety index value according to the illumination intensity, the atmosphere transparency and the shadow area proportion; when the light intensity safety index value exceeds a preset light intensity safety th
