Abstract
In a system having a control unit for triggering a restraint system for vehicles, and having a status acquisition device, such as a seat occupation device, from which a data record describing the presence or the non-presence of the condition is transmitted to the control device, upon a defined stimulation signal from the control unit to the status acquisition device the latter transmits a second data record to the control unit, which corresponds to the type characteristics and the type data. Thereby, type data are able to be recorded even in the case of a status acquisition device installed in an obstructed way in a motor vehicle.

11. A system, comprising:
-
a control unit configured to trigger a restraint system assigned to a seat of a vehicle in response to an event to be interpreted as an impact on an obstacle; and
a status acquisition device connected to the control unit via a transmission channel in order to activate the triggering only if a predefined condition is present, the status acquisition device configured to regularly transmit to the control unit via the transmission channel a data record corresponding to the presence or the non-presence of the condition, wherein the status acquisition device is configured to transmit to the control unit a second data record corresponding to type characteristics of the status acquisition device in response to a defined stimulation signal, the control unit configured to transmit the stimulation signal to the status acquisition device, and to supply the second data record received thereupon to a diagnosis device, in response to a diagnosis execution signal from the diagnosis device. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method for a diagnosis of a system having a triggerable restraint system, a control unit for triggering the restraint system when an event is recorded that is to be interpreted as the impact on an obstacle, and a status acquisition device for recording a condition for the triggering of the restraint system when the event is present, the status acquisition device being connected to the control unit via a transmission channel, the method comprising:
-
regularly transmitting, by the status acquisition device, a first data record which designates a presence or non-presence of the condition;
transmitting by the control unit a defined stimulation signal via the transmission channel, when executing the diagnosis; and
transmitting, by the status acquisition device, a second data record corresponding to type characteristics of the status acquisition device to the control unit via the transmission channel, in response to the stimulation signal;
wherein the control unit supplies the stimulation signal to the status acquisition device in response to a diagnosis execution signal from a diagnosis device, and supplies the second data record to the diagnosis device. - View Dependent Claims (19, 20)
