Abstract

The invention relates to a method for automatically adjusting the display brightness of a vehicle information terminal and a device. The present time information is received on the basis of a GPS and the sunrise/sunset time periodically provided based on CDMA is compared to the present time, and the day mode/night mode is automatically set according to the comparison result. simultaneously whether an illumination device for the vehicle is turned on/off is detected; the automatic light perception signal and the temperature around the vehicle are detected; the temperature around the vehicle is compared to the standard temperature set; the display brightness which is most suitable for the surrounding environment is regulated when the illumination device for vehicle is turned on/off and according to the comparison of the automatic light perception signal and the temperature, ensuring that the display brightness adapts to the variation of the running environment of the machine so as to obtain the optimum display brightness, thereby ensuring the excellent visual effects and eliminating the identity disorder of the service information.

Description

technical field [0001] The present invention relates to a method and a device for automatically adjusting display brightness on a vehicle information terminal, in particular to a vehicle information terminal equipped with a car navigation system or a telematics system, etc., using sunrise / Sunset time information, current time information, on / off of vehicle lighting devices (headlights, taillights), automatic light sense signal (auto_light sense signal) and ambient temperature sensing signal, method for automatically adjusting the display brightness of the terminal and its device. Background technique [0002] Recently, there is an increasing demand for vehicle information terminals such as car navigation devices and telematics systems. Usually, the car navigation device generally determines the current vehicle position based on the position information received from the GPS, and based on this, provides road travel information from the current geographic location to the des...
