Abstract
A level of vehicle (LOV) informing device mounted in a vehicle includes: an entrance detector determining whether the vehicle enters an entrance of a parking lot; a current location detector detecting a current location of the vehicle; an atmospheric pressure detector detecting an atmospheric pressure of the current location of the vehicle; a wireless communication unit performing wireless communication with an external device through a wireless communication network; and an LOV detector determining an LOV of the vehicle using a difference between a previous atmospheric pressure previously detected by the atmospheric pressure detector and a current atmospheric pressure currently detected by the atmospheric pressure detector, to determine the LOV of the vehicle at a parking time of the vehicle after the vehicle enters the entrance of the parking lot, and informing a user of the LOV.
