Abstract
A parking assistance device includes: a sensor configured to search for a parking space around a vehicle; a tire pressure monitoring system configured to measure and monitor a tire pressure of the vehicle; and an electronic control unit configured to calculate a moving distance of the vehicle moving to the parking space according to the tire pressure, to estimate a position of the vehicle by using the calculated moving distance, and to generate a parking command. The moving distance of the vehicle is calculated by using a moving distance per revolution of a tire measured and is set according to a tire pressure range to which the tire pressure of the vehicle belongs, a wheel pulse of the tire of the vehicle, and a reference wheel pulse per revolution of the tire.
