Method for tripping a restraint device in a vehicle
First Claim
1. A tripping method for a vehicle, which comprises:
- evaluating in an evaluation device a collision signal furnished by a sensor device;
transmitting coded information signals in both directions between the evaluation device and an ignition device electrically connected to an ignition element of a restraint device;
controlling the transmitting of the coded information signals by the evaluation device;
ending the transmitting of the coded information signals in dependence on the collision signal; and
furnishing a coded tripping signal for tripping the restraint device by the evaluation device to the ignition device in dependence on the collision signal.

Abstract
In a method for tripping a restraint device in a vehicle, coded information signals with status and diagnosis messages are transmitted in both directions between an evaluation device and an ignition device. To avoid the situation where a tripping signal for the restraint device may be delayed in its transmission to the ignition device because the data throughput in the transmission medium is high, the transmission of the information signals is interrupted. Accordingly, the transmission of the information signals in the forward and return directions is controlled by the evaluation device. As a function of a collision signal furnished by a sensor device, the transmission of the information signals is ended by the evaluation device, so that the transmission medium between the evaluation device and the ignition device remains free for a possibly ensuing tripping signal.
