Vehicular occupant protection system
First Claim
1. A vehicular occupant protection system comprising:
- an air bag sensor;
a base-signal generating unit configured to generate a base signal for abnormality diagnosis for the air bag sensor;
a diagnosis-signal generating unit configured to generate a diagnosis signal for the air bag sensor based on the base signal;
an abnormality diagnosing unit configured to execute the abnormality diagnosis by using an output signal that the air bag sensor outputs based on the diagnosis signal, the abnormality diagnosis being performed as an initial diagnosis started in response to turning on an ignition switch; and
a condition-signal generating unit configured to generate a condition signal for a start of generating the diagnosis signal,wherein the diagnosis-signal generating unit generates the diagnosis signal based on the base signal when the condition signal satisfies a given condition.

Abstract
A vehicular occupant protection system includes an air bag sensor; a base signal generating unit that generates a base signal for abnormality diagnosis for the air bag sensor; a diagnosis-signal generating unit that generates a diagnosis signal for the air bag sensor base on the base signal; an abnormality diagnosing unit that executes the abnormality diagnosis by using output signal that the air bag sensor outputs based on the diagnosis signal; and a condition-signal generating unit that generates a condition for a start of generating of the diagnosis signal. Here, the diagnosis-signal generating unit generates the diagnosis signal based on the base signal when the condition signal satisfies a given condition.
