摘要

A vehicle data bus system comprises a data bus to which several bus subscribers are connected for data transmission purposes. A positioning unit is provided as a bus subscriber and is equipped to determine at least vehicle position data and to transmit the determined vehicle position data to the data bus. The positioning unit comprises a positioning sensor system, which contains at least one GPS receiver and gyro-data detection means (12) in the form of a gyroscope or in the form of means for bus-side reception and evaluation of gyro-data. The positioning unit is also equipped to determine solar position data using the determined vehicle position data, and to transmit the determined solar position data to the data bus.
