Automated synchronized service intervals for vehicles
First Claim
1. A method of optimizing vehicle service intervals for a plurality of vehicle service items, the method comprising the steps of:
- selecting at least a first primary service item;
defining a plurality of recommended service intervals for different vehicle operating variables for the first primary service item;
periodically determining service intervals normalized to distance traveled for the first primary service item and predicting a minimum service interval based on a smallest result of periodic determination of service intervals;
selecting at least a first vehicle service item other than the first primary service item for service at the minimum service intervals;
the step of selecting at least the first primary service item comprising;
monitoring vehicle operating variables determinative of service intervals for a non-primary vehicle service item;
if required, for a particular non-primary service item, generating a service interval in terms of distance; and
determining an adjusted service interval for the non-primary vehicle service item based on a ratio of the minimum service interval and a service interval for the non-primary service item and multiplying the service interval for the non-primary service item by the ratio.

Abstract
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.
