Abstract

A vehicle computer system comprising a power management system for ensuring that continuous power is supplied to the computer system even when the car is turned off. The computer system comprises a client computer, a server, a plurality of peripheral devices, a power cable for connecting the vehicle battery to the client computer and the peripherals, a backup battery connected to the vehicle battery by a switch such that the switch is turned on when the power from the vehicle battery is low, and a power inverter for converting an direct current voltage from the vehicle battery or the backup battery into an alternating current for powering the client computer and the peripherals.

Claims

1. A vehicle computer system comprising:

a client computer;

a server connected to the client computer by one of a plurality of communication links;

a plurality of peripheral devices connected to the client computer by a second of the communication links;

a vehicle battery connected to the client computer by one of a plurality of power cables;

a backup battery being connected to the vehicle battery by a switch, wherein the switch is turned on when the vehicle battery is low on power; and

a power inverter for converting an direct current voltage from one of a vehicle battery and a backup battery into an alternating current, wherein the alternating current supplies power to the client computer and the plurality of peripheral devices.

2. The vehicle computer system of claim 1, further comprising a plurality of cameras attached to various locations around the periphery of a vehicle for transmitting images to the client computer.

3. The vehicle computer system of claim 2, further comprising a plurality of infrared sensors attached to various locations around the periphery of a vehicle and transmitting signals to an IrDa port within the client computer for client computer to turn the cameras on.

4. The vehicle computer system of claim 1, further comprising a plurality of infrared sensors attached to various locations around the periphery of a vehicle and transmitting signals to an IrDa port within the client computer for transmitting data to the server to apply the brakes of the vehicle.

5. The vehicle computer system of claim 1, wherein the client computer further comprises an internal hard drive including shock absorbent brackets for removably attaching the client computer to a location within a vehicle.

6. The vehicle computer system of claim 1, wherein the plurality of peripheral devices comprises a least one of a floppy diskette drive, a hard disk drive, A DVD (digital video disk), a CD-RW, a DVD-RW, a television tuner, a video display, a stereo, a digital camera, a tape drive, a PCMCIA drive, a CD-ROM drive, an OBD (On Board Diagnostic) system, a security system, a navigation system, a monitor, a printer, a plurality of speakers, a plurality of infrared sensors, a wireless link to the Internet, a joystick, a keyboard, a mouse, a printer, a modem, a scanner, a serial port and a parallel port.

7. The vehicle computer system of claim 1, wherein the plurality of communication links comprises at least one of a USB Port, a Fire Wire Port, a Serial Port, a USB Hub, a Fire Wire Hub, an Audio Hub, buses, interfaces including at least one of an ISA, an EISA, a MCA, a PCI, a SCSI, a PCMCIA, and a CardBus.

8. The vehicle computer system of claim 1, wherein the client computer further comprises a GPS data receiver for receiving signals from a satellite-based navigation system and performing calibration, signal processing, dead-reckoning, vehicle positioning, and route guidance functions.

9. The vehicle computer system of claim 1, wherein the client computer further comprises an audio input and voice and speech recognition software for converting speech to text and text to speech.
