On-board electrical system for motor vehicle, has program controlled operational data processing device receiving and processing operational data of motor vehicle, where operational data is collected by control devices

摘要

The system has control devices cross-linked together by a data bus, and a program controlled operational data processing device receiving and processing operational data of a motor vehicle. The operational data is collected by the control devices, and the operational data processing device is formed as a gateway for bi-directional data exchange between other two different data buses. The processing device comprises a program controlled memory, which repeatedly stores the operational data in a predetermined manner.
