process for operating a quasibusses for a personenschutzsystem,control device to control a personenschutzsystems and device for the transmission of data from sensors, at least one quasibus to a control unit to control a personenschutzsy.

摘要

The method involves attaching a quasi-bus to an electronic control unit (ECU) for controlling a personal protection system, where the quasi-bus has sensors (S1, S2, SN) e.g. radar, only for unidirectional synchronous transmission of data to the control unit. The data in control unit are transmitted in respective time slots when the sensors are operated. A fault indicating image is detected by the control unit based on the received data. A restart of the quasi-bus is executed by the control unit based on the image, and the last sensor (SN) at the quasi-bus is separated from operation. Independent claims are also included for the following: (1) a controller for controlling a personal protection system (2) a device for transmission of data from sensors to a controller over a quasi-bus to control a personal protection system.
