Abstract
A vehicular position estimation system estimates a portable terminal position with respect to a vehicle. Each of three or more in-vehicle communication devices is attached at a different position of the vehicle. Each of the multiple in-vehicle communication devices generates distance information indicating a distance from the in-vehicle communication device to the portable terminal. The vehicular position estimation system includes a position coordinate calculation portion that calculates a position coordinate of the portable terminal, and an area inside-outside determination portion that determines whether the portable terminal is inside the system actuation area.
