Abstract: A mechanical acceleration switch acting in response to a collision involving a vehicle tends to occur with chattering, thereby lowering the reliability of operation due to insufficient application of an ignition current to an igniter of an air bag in the vehicle. When the mechanical acceleration switch is closed and first-stage igniters are ignited, a forced igniter is turned on. Even if chattering occurs in the mechanical acceleration switch, the first-stage igniters and a backup capacitor are conductively connected by turning on a driving transistor, such that an electric current is sufficiently delivered to the igniters. As a result, it is possible to improve the reliability of the operation of starting the air bag. Furthermore, it is no longer necessary to increase a capacity of the capacitor and change the constitution of the mechanical acceleration switch to decrease chattering therewith.

Abstract: When an on-board power source is turned off, after a predetermined time has elapsed, a microcomputer 34 writes predetermined data in a nonvolatile memory 35, and when the on-board power source is turned on, the microcomputer 34 judges whether the predetermined data is written in the nonvolatile memory 35 or not. If the judgment shows that the predetermined data is not written in the nonvolatile memory 35, the microcomputer 34 determines a backup capacitor 32 not to be working normally. The predetermined time is shorter than the operating time of the microcomputer 34 determined by the discharge time of the backup capacitor when the backup capacitor is working normally, and is longer than the operating time of the microcomputer 34 determined by the discharge time of the backup capacitor when the backup capacitor is not working normally.
