Abstract: A method, a control unit, and a computer program for detecting a defective intake-manifold pressure sensor and/or a defective ambient-pressure sensor in an internal combustion engine having a variable valve timing are provided. The desired detection is carried out exclusively on the basis of a direct evaluation of the pressure upstream from the throttle valve and the pressure in the intake manifold. This method eliminates the need for deriving load signals from these pressures, at least for the determination as to whether at least one of the pressure sensors is defective.

Abstract: An arrangement (1) for controlling the torque of a drive unit (5) of a vehicle is suggested which increases driving comfort. The arrangement includes first means (10) which determines a desired value for the torque to be outputted by the drive unit (5). In addition, second means (15) are provided which adjusts the desired value while considering loads of the drive unit (5). This second means (15) corrects the torque, which is to be adjusted, in dependence upon the loss torques of the drive unit (5) and/or on the torque requirement of additional consumers which load the drive unit (5).
