Emergency report device for vehicle
First Claim
1. An emergency report device for a vehicle having a vehicle drive mechanism, the emergency report device performing an emergency report operation by electric power supplied from an electric power source including an auxiliary battery and a main battery, the emergency report device comprising:
- a power supply control unit that switches the electric power source from the main battery to the auxiliary battery when a supply voltage of the main battery is smaller than a predetermined threshold value; and
an auxiliary battery operational check unit that performs an operational check of the auxiliary battery;
whereinthe operational check of the auxiliary battery is performed at a time when the vehicle drive mechanism starts;
the operational check of the auxiliary battery is performed a first time when the vehicle drive mechanism starts a first time after an end of a previous day;
the operational check of the auxiliary battery is prohibited from being performed during the same day after the operational check of the auxiliary battery is performed the first time; and
the performing of the operational check of the auxiliary battery is based on a current input into the auxiliary battery operational check unit from the auxiliary battery.

Abstract
An emergency report device comprises: a power supply control unit that switches an electric power source from a main battery to an auxiliary battery when a supply voltage of the main battery is smaller than a predetermined threshold value; and an auxiliary battery operational check unit that performs an operational check of the auxiliary battery if the operational check of the auxiliary battery is being performed at a time when the vehicle drive mechanism starts, and if the operational check of the auxiliary battery is being performed for a first time during a period between an end of a previous day and a present time. The operational checking of the auxiliary battery is based on a current input into the auxiliary battery operational check unit from the auxiliary battery.
