Position estimation device, position estimation system, and position estimation method
A distance data between the portable device and the vehicle-side transmission and reception device is acquired. A movement speed of the portable device is calculated based on a change between a current distance data and a previous distance data. A position estimation distance for estimating the position of the portable device with respect to the vehicle is updated when the movement speed is less than a first speed. The position estimation distance is not updated when the movement speed is equal to or larger than the first speed. The position of the portable device is estimated according to the position estimation distance.
