Abstract
The invention relates to a method for operating a drive device (), which for the purpose of providing a driving torque comprises an internal combustion engine having a plurality of cylinders () that, during normal operation, supply a respective torque contribution, and at least one electric motor () operatively connected to said engine. To this end, in a diagnostic mode a cylinder-selective measurement of at least one characteristic operating variable is carried out, for which purpose in the diagnostic mode only the cylinder () to be measured is operated and the torque contributions of the remaining cylinders () are simulated by the electric motor ().
