<p><P>PROBLEM TO BE SOLVED: To allow a driver to reliably obtain the current positional information of a vehicle when the vehicle and a navigation system may stop due to battery exhaustion. <P>SOLUTION: The voltage of a battery 5 to supply power to a motor 2 and the navigation system 4 is monitored by a battery-managing ECU 6. The controller 9 of the navigation system 4 acquires data about the voltage of the battery 5 monitored by the battery-managing ECU 6, and directly transmits the current positional information of the vehicle 1 to a portable terminal 7 connected by wire or short-range wireless communication, when the acquired voltage data reaches the lowest value to operate the motor 2 and the navigation system 4. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
