Engine management control systems basically consist of injection and ignition control. Additionally, closed loop control systems incorporating air fuel ratio control, automatic idle speed control and cylinder selective knock control have proven to be essential.To keep the performance stable during the car's lifetime, extensive use is made of self-adaptive strategies. As a new feature of engine management control, the self-adaptive canister purge control improves driveability and prevents the leakage of fuel vapors. To simplify the closed loop control algorithms primarily during transient operation conditions a sophisticated sequential fuel injection is added. The paper presents the aforementioned self-adaptive closed loop control strategies and the MOTRONIC MI. 3 ECU. Future development trends in engine management and drive train control demand powerful communication links like the Controller Area Network (CAN). This requirement and its planned realisation is discussed.
