PROBLEM TO BE SOLVED: To control remotely various on-vehicle units through the use of an out-vehicle telephone set by allowing the system to have a transmission reception section making 2-way communication to a telephone set at the outside of a vehicle and a control circuit that control various on-vehicle units corresponding to a specific identification signal included in a voice signal received from the transmission reception section. SOLUTION: A transmission reception section 1 makes 2-way communication with an out-vehicle telephone set by using a radio wave as a medium. An on- vehicle unit group 2 is an on-vehicle unit including a theft prevention unit 21, an air-conditioner unit 22 and an engine control unit 23 and connects to a control circuit 3. A leased signal line is set or a LAN use data bus mounted on a vehicle is used as a means to connect the on-vehicle units 21-23 to the control circuit 3. The control circuit 3 extracts the specific identification signal included in a voice signal entered from the transmission reception section 1 and controls the onvehicle units 21-23 corresponding to the specific identification signal and is provided with a function as a hand-free device in common. |
