Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of priority to Korean Patent Application No. 10-2022-0042188, filed in the Korean Intellectual Property Office on Apr. 5, 2022, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to a vehicle charging control device and a method thereof, and more particularly, to a technology for controlling a charging location of a vehicle by using an autonomous parking function. BACKGROUND In the future electrification era, a simpler and faster charging scheme is required for an electric vehicle charging scheme, and to this end, a wireless charging scheme or an autonomous charging scheme technology should be based in addition to a fast-charging scheme. For wireless charging of a vehicle, it is necessary to propose a scheme of contacting a wireless power transmission pad and a wireless power reception pad of a vehicle at an accurate location. In addition, it is necessary to automate the charging process to provide various conveniences to a driver during charging which takes a long time. As a parking convenience function, a remote smart parking assist function is applied to autonomous vehicles that can help parking and exiting remotely from the outside of the vehicle by using an omnidirectional camera and an ultrasonic sensor. By utilizing such a remote smart parking assist function, it is possible to recognize parking lines and surrounding objects. In addition, by automatically controlling steering, vehicle speed, and gear shifting, it is possible to provide remote parking and un-parking services even when a driver is not in the vehicle. In addition, a wireless charging function may be provided by contacting a wireless transmission/reception pad between an electric vehicle and a charger, but the electric vehicle may not be charged due to a defective contact between the wireless transmission/reception pads. In addition, it is necessary to consider what kind of convenience is provided to the driver during the charging time of an electric vehicle, which is longer than the refueling time of an existing internal combustion engine vehicle.
