CARTRONIC SYSTEM ARCHITECTURE FOR ENERGY AND POWERTRAIN MANAGEMENT

Abstract Networking mechatronic components and sub-systems in a vehicle necessitates a concept of order to organize the controlling and regulating systems. One such concept, called CARTRONIC®, has been developed by Robert Bosch GmbH. This article describes the CARTRONIC system architecture for integrating systems in powertrain management as well as for electrical and thermal energy management. The modules and functions of each control system are shown. The physical relationships between the flows of mechanical, thermal and electrical energy in the vehicle are derived, and it is shown how this can be optimized by a system architecture designed for the whole vehicle.
