ABSTRACT:
A hybrid vehicle has an internal combustion engine and an electric motor, each of which can deliver a torque, particularly in order to drive at least one vehicle wheel. An exhaust gas system having a catalytic converter system is assigned to the internal combustion engine. The conversion activity of the catalytic converter system depends on predetermined activity parameters. The value of the conversion activity is determined in a predetermined time interval T_Kat. The torque output of the electric motor is increased, preferably depending on the load and the torque output of the internal combustion engine is reduced in order to attain a predetermined conversion threshold of the conversion activity of the catalytic converter system, if the value of the conversion activity lies below said threshold. For this purpose, a device is provided for controlling the torque output of the internal combustion engine and of the electric motor.
