Patent ID: 8090518

Claim:
A method for operating a drive system comprising at least an internal combustion engine and being arranged in a motor vehicle for the purpose of driving the motor vehicle, the method comprising the steps of: determining a value for a driver-requested torque for a driver of the motor vehicle, and wherein in a first operating mode of the drive system, the method comprises the steps of: determining a first control signal as a function of the value determined for the driver-requested torque, in order to realize the driver-requested torque as a function of the determined first control signal, actuating at least one first final control element which influences an air path of the internal combustion engine, determining a specific value for a characteristic of the internal combustion engine which is representative of an actual value for a basic torque which is actually produced by the internal combustion engine based on a setting of the first final control element, as a function of the specific value for the characteristic, determining a parameter value for a filter in such a way that a setpoint value for the torque which is determined by filtering the value for the driver-requested torque as a function of the determined parameter value is brought closer to the actual value for the basic torque, saving the parameter value for the filter assigned to the specific value for the characteristic, and wherein in a second operating mode of the drive system, the method comprises the steps of: determining the specific value for the characteristic, determining the parameter value for the filter as a function of the specific value for the characteristic, predefining the setpoint value for the torque by filtering the value for the driver-requested torque as a function of the determined parameter value, determining at least one second control signal as a function of the predefined setpoint value for the torque, in order to realize the predefined setpoint value for the torque as a function of the second control signal, actuating at least one second final control element which influences the torque produced by the drive system outside the air path.
