Method and device for measuring an engine load of a drive motor of a vehicle
First Claim
1. A method for measuring a driving output characterizing an engine load of a drive motor of a vehicle, comprising:
- ascertaining, using a clutch sensor, if the drive motor is coupled to a drive train of the vehicle;
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 the drive train of the vehicle and during which the vehicle is moving;
wherein the driving distance in the driving distance counter is incremented only when both (i) it is ascertained that the drive motor is coupled to the drive train of the vehicle, and (ii) the vehicle is moving.

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.
