Patent ID: 7817066

Claim:
An in-vehicle computer system, which controls various operations of plural electronic devices in a vehicle, comprising: a display, which is electrically connected to a mode switch, the mode switch being switched between a regular mode and a backup mode; a host computer, which is electrically connected to the mode switch, uses a bus to connect to the electronic devices in the vehicle, and includes a central processing unit (CPU) and a storage medium, the storage medium storing plural graphical interfaces corresponding to the operations of the electronic devices, respectively; a backup storage medium, which stores at least one backup graphical interface corresponding to at least one operation of the electronic devices; a backup graphical processor, which is electrically connected to the backup storage medium and the mode switch; and a backup microprocessor, which is electrically connected to the backup graphical processor and at least one of the electronic devices; wherein when the host computer functions ordinarily, the mode switch is in a regular mode as a default, the CPU extracts the graphical interfaces from the storage medium and presents the captured graphical interfaces on the display, and the CPU controls the operations of the electronic devices through the graphical interfaces; and when the host computer is out of order, the mode switch switches the regular mode to a backup mode, the backup microprocessor controls the backup graphical processor to extract the at least one backup graphical interface from the backup storage medium for graphical processing and further presentation on the display, and the backup microprocessor uses the at least one backup graphical interface to control at least one operation of the electronic devices corresponding to the at least one backup graphical interface.
