The invention discloses a method and device for adjusting the light transmittance of a windshield, and belongs to the technical field of vehicle control. The method comprises the steps that physiological feature information of a driving object of a vehicle, environment information of a target position and first illumination intensity are obtained, and the first illumination intensity is the illumination intensity actually borne by the driving object at the target position under the condition that light transmittance of a windshield of the vehicle is initial light transmittance; determining second illumination intensity matched with the driving object under the environment information of the target position according to the physiological feature information of the driving object and the environment information of the target position; based on the difference between the first illumination intensity and the second illumination intensity, determining target light transmittance according to the first illumination intensity and the second illumination intensity; and adjusting the light transmittance of the windshield to the target light transmittance. According to the method, the matching degree of the target transmittance determined by the method and the driving object is relatively high, the transmittance adjustment flexibility is relatively high, the accuracy is relatively high, and the driving safety of the vehicle can be further improved.
本申请公开了一种挡风玻璃透光度的调整方法和装置,属于车辆控制技术领域。方法包括:获取车辆的驾乘对象的生理特征信息、目标位置的环境信息和第一光照强度,第一光照强度为车辆的挡风玻璃的透光度为初始透光度的情况下,驾乘对象在目标位置实际承受的光照强度;根据驾乘对象的生理特征信息和目标位置的环境信息,确定在目标位置的环境信息下驾乘对象匹配的第二光照强度;基于第一光照强度和第二光照强度不同,根据第一光照强度和第二光照强度,确定目标透光度;将挡风玻璃的透光度调整为目标透光度。该方法确定的目标透光度与驾乘对象的匹配度较高,透光度的调整的灵活性更高、准确性更高,进而能够提高车辆的行驶安全性。
