<p>In an in-vehicle emergency call apparatus, after a vehicle battery starts electric discharge, electric currents flowing in from the vehicle battery ar e integrated to calculate a consumed electric current integrated value. When the consumed electric current integrated value reaches a specified value, a position information transmission operation may be performed. In such a case, even after the consumed electric current integrated value reaches the specified value, electric power is continuously supplied from the vehicle battery to the electric power supply device. The position information transmission operation is thereby performed continuously. The position information can be thus continuously transmitted to a service center as much as possible ; a service of pursuing a stolen car can be provided as much as possible.</p> |
