Data communications method, especially for vehicle occupant protection system, enables simple, reliable and timely evaluation of measurement - involves acquiring measurement values in measurement units on receiving measurement command, transferring measurement results sequentially to control unit

摘要

The method is used with a system with a primary control unit (6) and several measurement value acquisition units (1-4) connected to via a bus (5) and involves sending a measurement command from the control unit to the measurement units to initiate a measurement operation. Measurement values are acquired in the measurement units on receiving the measurement command and measurement results are transferred sequentially to the control unit as long as they do not have critical values requiring a reaction in the control unit.
