Motor vehicle e.g. passenger car`s, system and safety relevant component`s performance diagnosing device, has warning device outputting warning signal to vehicle user if measured state variable data exceeds warning threshold level

摘要

The device has a measuring device (2-7) for measuring the performance relevant state variable data of a motor vehicle component. A route length input device (10) inputs a planned driving route length, and a control device (8) adjusts a warning threshold level assigned to the state variable. A warning device (11) outputs a warning signal to the vehicle user if the measured state variable data exceeds the warning threshold level. An independent claim is also included for a method for diagnosis of the performance of a component of a motor vehicle.
