The disclosure relates to a vehicle.
A vehicle, which is a machine that travels on a road by rotating wheels, is equipped with various devices for protecting occupants, assisting driving, and improving riding comfort.
An accident may occur due to a breakdown of the vehicle itself, or may occur due to negligence of a driver of the vehicle, negligence of a driver of another vehicle, or road conditions.
Recently, various technologies have been developed for preventing an accident of a vehicle. As an example, technologies have been developed to install a distance sensor in a vehicle to detect an obstacle around the vehicle and warn a driver of the obstacle. Through this method, accidents may be prevented in advance.
