摘要:
Described here is a process for controlling a passenger protection system by means of a CPU in conjunction with acceleration signals and the existence of at least one trigger inhibiting signal from a manually operated trigger inhibitor or a seat occupancy detection device. This process prevents errors in the CPU. For this purpose, monitoring of the trigger inhibitor and the seat occupancy detection devices is provided in an evaluation unit parallel to the CPU, in order to set an ignition inhibiting signal, as soon as at least one of these devices sets a trigger inhibiting signal. The ignition inhibiting signal influences the inhibiting device located between the CPU and the passenger protection device, disabling the trigger. This makes it impossible for an error in the CPU to trigger the passenger protection device inadvertently.
