ABSTRACT:
A method and an arrangement for monitoring a torque of a drive unit (1) of a vehicle (5) are suggested. The method and arrangement make possible a reliable detection of a fault condition for an essentially constant actuation of an operator-controlled element. The torque, which is to be monitored, is compared to a permissible torque. The permissible torque is readjusted to the torque, which is to be monitored. A fault is detected when the torque, which is to be monitored, deviates from the permissible torque by more than a first pregiven value. The fault is only detected for the case wherein a position of an operator-controlled element, especially an accelerator pedal position, lies within a pregiven tolerance range at least since a first pregiven time.
