Abstract

A method for measuring an engine load of a drive motor in a vehicle. Here, at least one parameter which characterizes the engine load is allocated a driving distance equivalent. This driving distance equivalent is then incremented by a driving distance counter. If the vehicle is equipped with a sailing functionality, the driven distance is counted only if the vehicle is moving and the drive train is coupled to the drive motor without slip. A rate of rotation sensor, a clutch sensor and a driving distance counter able to be switched on and off are required for running the method of the present invention. A computer program is used in addition.

Claims

1-11. -11. (canceled)

12. A method for measuring a driving output characterizing an engine load of a drive motor of a vehicle, comprising:

incrementing continuously a driving distance in a driving distance counter, the incremented driving distance being precisely the driving distance of the vehicle during which the drive motor is coupled to a drive train of the vehicle and during which the vehicle is moving.

13. The method as recited in claim 12, wherein coupling of the drive motor to the drive train is assumed when a clutch is closed largely without slip.

14. The method as recited in claim 12, wherein the driving distance during which the drive motor is coupled to the drive train of the vehicle is displayed to the driver of the vehicle.

15. A device designed to:

increment continuously a driving distance in a driving distance counter, the incremented driving distance being precisely the driving distance of the vehicle during which the drive motor is coupled to a drive train of the vehicle and during which the vehicle is moving.

16. A computer program product including program code which is stored on a machine-readable carrier, the program code, when executed on a computer or control unit of a vehicle, causing the computer or control unit to perform:

incrementing continuously a driving distance in a driving distance counter, the incremented driving distance being precisely the driving distance of the vehicle during which the drive motor is coupled to a drive train of the vehicle and during which the vehicle is moving.
