The BMW 750 i has interconnected electronic systems for controlling the engine, automatic transmission, and driving stability. The authors describe the objective and concept of the drive train and driving stability electronics, the individual functions, and their interplay. They also present the various measures taken to make the drive-management system reliable; these include separate cylinder controllers, duplication of all sensors and actuators, reduction in the number of components by using ICs, continual microprocessor supervision of the performance control system, and recording of defective performance of the electronic control or transmissions for later diagnostic ease and accuracy.
