Data transmission system for e.g. hybrid vehicle, has data transmission units structured in master-client-system architecture that enables flexible bidirectional data transfer between master-control unit and client-control units

摘要

The system has data transmission units for transmitting and receiving data information. The data transmission units are structured in a master-client-system architecture (1), which enables a flexible bidirectional data transfer between a master-control unit (2) and client-control units (3, 5, 7, 9, 11) that are assigned in the master-control unit. A bidirectional transfer protocol for transmission of energy data to an electrical energy on-board supply system of a motor vehicle is defined in the master-client-system architecture.
