ABSTRACT:
A method of regulating the actual lambda value for an internal-combustion engine of a motor vehicle in a closed control loop is provided. A lambda setpoint is transferred to a controller for influencing an injection calculation for the internal-combustion engine, and an actual lambda value, which occurs at the output of a controlled system as a function of the injection calculation, is returned to the controller. At least one system parameter of the controlled system is determined, and the determined system parameter is transferred to a Smith predictor added to the controller for compensating the influence of the system dead time on the control loop characteristics.
