2001-01-1326 Generic Integrated PowerTrain Management IPM® Interface as a Standard

A generic Powertrain Interface is proposed, to provide a global and optimized inter-communication between all the new different electro-mechanical components to be integrated, associated to the traditional thermal engine, as starter-generator, automated transmission, anti-blocking system, navigation, or battery management. This interface is defined as a standard, based on the minimal inputs data needed by each component or functional group, and independent from any hardware communication support. A first example is described, using a standard CAN link between an engine management and an automated transmission, for new optimal torque and speed synchronization functionality. An extension is proposed, centered on the Siemens Integrated PowerTrain IPM® system described in this paper.
