Only when the entered code number matches a predetermined number, the process proceeds to step 3. In step 3, an object to be controlled (for example, release of home auto lock, activation of air conditioner, lighting of lighting, etc.) is selected. Set. In Step 4, it is determined whether or not the vehicle position has reached a predetermined distance range from the point where the vehicle position is automatically set. If it is determined that the vehicle has reached the predetermined distance range, automatic calling to the telephone number set in Step 5 is performed. When a call is made and the line is connected, the control signal of the activation target (for example, auto-lock, air conditioner, lighting, etc.) set in step 3 is transferred via the telephone line. At the transfer destination, the type of the control signal transmitted via the telephone line is determined, and the control target is activated based on the determination result.
