Abstract
A remote engine starting system includes a portable terminal that is carried by a user and a vehicle that allows an engine to be started in response to receiving an engine start signal transmitted from the portable terminal. The vehicle periodically transmits a query signal for establishment of a wireless communication link with the portable terminal to a predetermined range surrounding the vehicle to define a predetermined wireless communication area of the vehicle. A control unit of the portable terminal determines, based on whether the wireless communication link with the vehicle is established, whether the portable terminal is within the wireless communication area. The control unit transmits an engine start signal when the portable terminal enters the wireless communication area surrounding the vehicle while automatic start setting is enabled by the user.
