The invention relates to a photovoltaic sensing driven automobile self-adaptive glass color change regulation and control device and method. The method comprises the following steps that photovoltaic power generation films installed at different positions of an automobile are used for sensing light intensity from different directions, and direct-current voltage signals are generated; carrying out filtering and voltage regulation on the direct current voltage signal; performing analog-to-digital conversion on the filtered and voltage-regulated direct-current voltage signal to obtain a digital voltage signal; whether the light transmittance of the electrochromic films located at different positions of the automobile needs to be adjusted or not is judged, and digital control signals are formed; performing digital-to-analog conversion on the digital control signal to obtain an analog voltage signal; performing filtering and voltage regulation on the analog voltage signal to obtain a voltage control signal; and performing power amplification on the voltage control signal, and driving the electrochromic film to perform corresponding light transmittance adjustment through the amplified voltage control signal. The system can accurately and quickly respond to external light changes, and the visual comfort and the driving safety of a driver are remarkably improved.
