Patent abstract
Power is supplied to an ECU (20) from an on-vehicle battery (41). When an ignition switch (42) is switched from the OFF state to the ON state upon vehicle engine start, the ECU (20) is switched from the power saving mode to the normal mode and a CPU (31) executes initial processing. Moreover, when a user puts on a seat belt and a seat belt switch (44) is switched from the ON state to the OFF state, the ECU (20) is switched from the power saving mode to the normal mode and the CPU (31) executes the initial processing. Thus, the initial processing is executed at a comparatively short interval and it is possible to improve the reliability of the CPU (31).
