摘要： A method for forming a signal relating to the quantity of exhaust gas recirculated in an internal combustion engine. The signal for the quantity of recirculated exhaust gas is formed on the basis of a signal for the stream of fresh gas fed to the internal combustion engine and a signal for the entirety of the stream of gas fed to the internal combustion engine. The signal for the entirety of the stream of gas which is fed is formed from a series of characteristic operating variables. These characteristic operating variables include, inter alia, the pressure in the intake tract, which can either be detected by means of a sensor or be formed from standby signals. The signal for the quantity of recirculated exhaust gas can be provided with a dynamic correction signal. Furthermore, the signal for the quantity of recirculated exhaust gas can be used in an exhaust gas recirculation valve with position reporting facility to identify an adaptive correction signal.

摘要： The invention is directed to an arrangement for adjusting an operating characteristic quantity of an internal combustion engine such as for the idle speed control with a redundant drive. Two windings of the drive are driven via two separate lines from two separate output stages. When a defect is detected via an electrical monitoring unit, a safety logic unit transfers the full operation for the drive of the throttle flap to the output stage and the winding corresponding thereto which are not affected by the defect. In this way, a noraml idle speed of the engine is assured even in the presence of a single defect.
