Abstract

In the restraint system, in which coupled to a bus line are a central control unit and a plurality of data processing units that are provided to trigger restraint devices, a plurality of data channels that are clearly separable from each other are to be transmittable. In this context, data of high priority and high time-related urgency are transmitted with a high signal level and a high bit rate, data of lower priority and lower time-related urgency are transmitted with a low signal level and a low bit rate, data of high priority and lower time-related urgency are transmitted with a high signal level and a low bit rate, and data of a lower priority and high time-related urgency are transmitted with a low signal level and a high bit rate.
