A system and process for optimizing vehicle service intervals for a plurality of vehicle service items begins with determination of a minimum service interval. The minimum service interval is set by the need to provide critical, though routine services such as engine oil changes and chassis lubrication. Multiple potential service intervals exist for at least one component, typically engine oil changes, based on different vehicle operating variables. Depending upon the character of vehicle use, one variable will control determination of the recommended interval for engine oil, which, after conversion to distance, is compared with the chassis lubrication to find the minimum service interval. Additional components/fluids are included for service based on operational variables selected to determine service intervals for these components.

Automated synchronized service intervals for vehicles

The invention integrates a general purpose computer with a controller area network to effect an inspection regimen through the controller area network A convenient user interface, combining handheld instruments and convention displays and printers allows the driver to interact with the system. The computer provides storage for programs and processing power to implement test regimens in logical order relating to completion of the inspection.

Automated vehicle inspection system

The invention integrates a general purpose computer with a controller area network to effect an inspection regimen through the controller area network. A convenient user interface, combining handheld instruments and convention displays and printers allows the driver to interact with the system. The computer provides storage for programs and processing power to implement test regimens in logical order relating to completion of the inspection.

A data transmission system for external use with a controller area network is installed on a motor vehicle undergoing high intensity electromagnetic interference susceptibility testing. The data transmission system includes a fiber optic cable extending from the immediate vicinity of the truck to a site relatively remote to the truck and out of the effective area of the artificially generated electromagnetic interference. An optical/electrical coupler in close proximity to the motor vehicle is connected to the vehicle controller area network to convert messages occurring on the network to optical signals. The connection is provided by an electrical cable constructed of a twisted pair of wires. The optical/electrical coupler is also connected to an end of the fiber optic cable in the vicinity of the truck. A remote data processing device is attached to the remote end of the fiber optic cable by an interface card installed in the remote data processing device. The interface card converts optical signals to controller area network compatible electrical signals for evaluation.
