Abstract: A system for prompting an on-vehicle wireless communication module in poor communication quality and method thereof, in which the in-car computer starts a wireless communication module to detect the receiving quality thereof and to obtain a detecting signal result during the alert mode of the security controller is set after the ignition switch is switched off, and the in-car computer outputs a voice prompt message when the ignition switch is switched on again if the detecting signal result does not surpass a predetermined receiving quality default value. The in-car computer also stores each poor communication quality location in the electronic map so that a voice prompt message is automatically produced when passing each poor communication quality location on a subsequent occasion.

Abstract: An in-vehicle computer system includes a host computer, a mode switch and a backup microprocessor. When the host computer functions ordinarily, the mode switch is in a regular mode as a default, and the host computer uses various graphical interfaces on a display to control the operations of electronic devices implemented in a vehicle. The electronic devices can include a digital versatile disc (DVD) player, an MP3 player and a global positioning system (GPS). When a total failure of the computer occurs, the mode switch is switched to a backup mode, and the host computer is replaced by the backup microprocessor to control a backup graphical processor to extract backup graphical interfaces from a backup storage medium for graphical processing and further presentation on the display. Thus, a driver can continuously control the corresponding electronic devices through the backup graphical interfaces on the display.
