PARKING ASSISTANCE DEVICE
First Claim
1. A parking assistance device comprising:
- an emission unit configured to emit ultrasonic waves in at least an outward lateral direction of a vehicle;
a reception unit configured to receive reflection waves from an object reflecting the emitted ultrasonic waves; and
an object determination unit configured to, based on a change in a detection state of an object that exists on a far side of a target parking region in which the vehicle is to be parked, the detection state having been specified based on reflection wave data obtained using the reflection waves from the object, determine a feature relating to the height of the object as the vehicle enters the target parking region.

Abstract
Provided is a parking assistance device that can obtain information regarding the height from a parking road surface of an object without acquiring height information of an object in advance. The parking assistance device includes: an emission unit configured to emit ultrasonic waves in at least an outward lateral direction of a vehicle; a reception unit configured to receive reflection waves from an object reflecting the emitted ultrasonic waves; and an object determination unit configured to receive the reflection waves from an object existing on a far side of a target parking region as the vehicle enters the target parking region, and determine a feature relating to the height of the object based on a change in a detection state of the object, which was specified based on the obtained reflection wave data.
