Due to the social and legal requirements on the engine and the entire vehicle the functional scope of modem Engine Management Systems (EMS) has dramatically grown. As driving forces of this ongoing process the reduction of fuel consumption and emissions have to be considered - in the past as well as in the future. But also increasing comfort and diagnosis demands lead to a further increasing complexity of today's and future EMS. In order to securely control this complexity a well structured functional architecture in combination with physically based functions forms the necessary basis. With the launch of the MOTRONIC ME7 Bosch introduced a torque based functional architecture to meet these requirements. This includes not only the mentioned optimization of engine performance and compliance with legal standards on emission, fuel consumption and diagnosis.
