Recording a wear status for an operating medium and setting a replacement interval

摘要

The method involves measuring the temperature of an operating medium, where a current wear condition of the operating medium is determined. The operation of a vehicle gearbox system is affected such that a specific change of time point of the operating medium coincides with the end of life-span of the operating medium. An independent claim is included for an arrangement for setting a replacement interval of an operating medium in a vehicle gearbox system, particularly using a retarder.
