Problems solved by technology
Because the car instrument and audio entertainment system are distributed in different places on the car, for example, the instrument is distributed in front of the steering wheel, and the audio CD is distributed in the middle and lower part of the center console; therefore, there is not only no space between the vehicle driving information display system and the audio entertainment display system. Interrelated, and there is no interrelated information sharing, the comprehensiveness is not strong, and it is a waste of LCD display resources

The invention relates to a vehicle central information display device; the output terminals of an instrument disc MCU and an acoustic MCU are respectively connected with a driver by a conversion circuit and information is displayed on the LCD screen of an instrument disc display module after compared by the driver. The invention also discloses a vehicle central information display method, comprising the steps as follows: the vehicle information output by the instrument disc display module MCU and the acoustic information output by the acoustic display module MCU are compared through the conversion circuit, subsequently, the information with higher priority is output to the LCD screen of the instrument disc display module so as to be displayed. The device and the method of the invention can comprehensively display the vehicle information and the acoustic information, thus saving the LED screen resource.
Description
technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle central information display device and a display method thereof. Background technique [0002] At present, each display information system on the car is very single, not comprehensive, and it is a waste of LCD display resources. For example, the car instrument mainly displays mileage accumulation, mileage subtotal, clock and other aspects on the LCD display. The display content is as follows: figure 1 shown. The audio entertainment system mainly displays the audio source mode, frequency band number, CD playing time, etc. on the LCD display, and the displayed content is as follows: figure 2 shown. Because the car instrument and audio entertainment system are distributed in different places on the car, for example, the instrument is distributed in front of the steering wheel, and the audio CD is distributed in the middle and lower part of the center console; there...
