The invention provides a light quantity adjusting method and system and an automobile. The light quantity adjusting method comprises the steps that the light intensity difference between the first light intensity corresponding to light entering a cab and the ambient light intensity of a first area in the cab is obtained, and the light entering the cab is transmitted to the first area through a light-transmitting screen, the first area comprises an area where human eyes of the driver are located; under the condition that the light intensity difference is larger than a preset light intensity difference threshold value, the inclination angle of the light-transmitting screen relative to the first reference surface is adjusted according to a preset strategy so as to reduce the amount of light transmitted to the first area; by adjusting the inclination angle of the light-transmitting screen relative to the first reference surface, the shading amount of the shading structure of the light-transmitting screen can be adjusted so as to adjust the light-transmitting amount of the light-transmitting screen and the amount of light transmitted to the first area, and the first reference surface is perpendicular to the end face where the vehicle body floor in the cab is located and perpendicular to the length direction of the vehicle body. The light entering amount of the first area can be automatically adjusted based on the external light intensity, and the driving safety of a driver is guaranteed.

    本发明提供一种光量调整方法、系统及汽车,光量调整方法包括:获取入射到驾驶室内的光线对应的第一光强度与驾驶室内第一区域的环境光强度的光强度差,入射到驾驶室内的光线经透光屏透射至第一区域,第一区域包括驾驶员的人眼所处区域;在光强度差大于预设光强度差阈值的情况下,按照预设策略调整透光屏相对于第一基准面的倾斜角度,以减少透射至第一区域的光量;通过调整透光屏相对于第一基准面的倾斜角度,可调整透光屏的遮光结构的遮光量,以调整透光屏的透光量、透射至第一区域的光量,第一基准面与驾驶室内车身地板所在端面垂直,且与车身的长度方向垂直。本发明可以实现基于外界光强自动调整第一区域的进光量,保证驾驶员的行车安全。
