Abstract
An arrangement for controlling the drive power of a motor vehicle has at least two control units for controlling at least two changing variables for influencing the drive power. The variables are independent of each other. The arrangement further includes at least one measuring device for detecting an operating variable of the drive unit and/or of the motor vehicle. This one measuring unit includes at least two redundant sensors with the output signal of one sensor being supplied to a first control unit and the output signal of another sensor being supplied to a second control unit. Both control units monitor the measuring device on the basis of the output signals with additional monitoring measures being carried out on the basis of the monitoring results of the two control units.
