Abstract
A vehicular voltage regulating system is mounted on an automotive vehicle equipped with an on-board electronic control device which is required to operate even when an ignition switch is turned OFF. The electronic control device is adapted to control operation of a passive seat belt arrangement. The voltage regulating system is comprised of detecting means for detecting starting operation for the electronic control device and outputting a first signal. Voltage regulation commanding means is provided to command voltage regulation by outputting a second signal for a predetermined time from a time at which the detecting means outputs the first signal. Additionally, regulating means for regulating a first voltage supplied directly from an on-board battery of the vehicle into a second voltage at a predetermined level and supplying the second voltage to the electronic control device in response to the second signal from the voltage regulation commanding means, thereby making unnecessary so-called stand-by current to the electronic control circuit thus to prevent overdischarging of the battery.
