Parking assistance device using tire pressure monitoring system
First Claim
1. A parking assistance device comprising:
- a sensor configured to search for a parking space around a vehicle;
a tire pressure monitoring system configured to measure 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;
estimate a position of the vehicle by using the calculated moving distance; and
generate a parking command,wherein the moving distance of the vehicle is calculated by using a moving distance per revolution of a tire, and the moving distance of the vehicle 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,wherein the parking assistance device releases a parking assistance function when a tire pressure difference between a first wheel and a second wheel, which is different from the first wheel, deviates from a preset difference,wherein the moving distance of the vehicle is the wheel pulse of the tire of the vehicle multiplied by the moving distance per revolution of the tire and divided by the reference wheel pulse per revolution of the tire,wherein the wheel pulse of the tire of the vehicle is a value measured through a wheel sensor of the vehicle, andwherein the moving distance per revolution of the tire is a value measured and set according to the tire pressure range.

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.
