摘要： A method for the quality assurance of exhaust gas behavior in a motor vehicle, particularly in a hybrid vehicle, includes monitoring an on-board-diagnosis function; providing a journey counter a diagnosis counter, and a nominal diagnosis frequency value; incrementing the journey counter following the beginning of a driving cycle; generating an actual diagnosis frequency value using a combination of the diagnosis counter and the drive counter; and establishing a difference between the nominal diagnosis frequency value and the actual diagnosis frequency value. If the difference falls short of a threshold: a control method is selected, which is designed to successfully complete a currently running OBD of the OBD function and to initiate and complete a non-running OBD. Following the completion of the OBD of the OBD function, the diagnosis counter is incremented and the motor control restored to an original motor control.
