Abstract

A car stereo head unit includes a control system coupled to the car control computer of the car carrying the car stereo head unit by a CAN BUS, a front face panel electrically coupled with the control system and providing a touchscreen, a display driver module system, an intelligent computer system module, an antenna embedded GPS receiver system and a wireless communication module system, and a FM/AM radio receiver module, a DVD/SD/USB player module, a digital TV receiver and player module and an audio output system electrically coupled to the control system. Subject to touch control through the touchscreen, the control system controls the audio output system to play sound and the touchscreen to play videos. By means of the intelligent computer system module and the wireless communication module system, the car stereo head unit is allowed for mobile phone application and internet access.

Claims

1. A car stereo head unit installed in a dashboard center console of a car, comprising:

a control system comprising a car power converter electrically coupled to a car battery power supply system of said car to obtain the necessary working power supply from said car, and a linear communication system electrically coupled to a car control computer of said car;

a front face panel electrically coupled with said control system, said front face panel comprising a touchscreen, a display driver module system adapted for driving said touchscreen, an intelligent computer system module, an antenna embedded GPS receiver system, and a wireless communication module system;

a FM/AM radio receiver module electrically coupled to said control system;

a DVD/SD/USB player module electrically coupled to said control system;

a digital TV receiver and player module electrically coupled to said control system; and

an audio output system electrically coupled to said control system;

wherein, subject to touch control through said touchscreen of said front face panel, said control system controls said audio output system to play sound and said touchscreen of said front face panel to play videos;

by means of said intelligent computer system module and wireless communication module system of said front pace panel, the car stereo head unit is allowed for mobile phone application and internet access.

2. The car stereo head unit as claimed in claim 1, wherein said linear communication system that electrically connects said control system to said car control computer of said car is constructed subject to CAN BUS (controller area network bus) protocol.

3. The car stereo head unit as claimed in claim 1, wherein said wireless communication module system of said front pace panel is a Wi-Fi/GPRS (3G/4G) wireless communication module system.

4. The car stereo head unit as claimed in claim 1, wherein said audio output system comprises an audio DSP (digital signal processor) system, an audio control system, and an audio power amplifier system for audio output through a speaker system that is installed in said car.

5. The car stereo head unit as claimed in claim 1, wherein said control system of said car stereo head unit is also electrically coupled with a drive recorder system.

6. The car stereo head unit as claimed in claim 1, wherein said FM/AM radio receiver module is electrically coupled with a radio antenna.
