METHOD AND APPARATUS OF DETERMINING POSITION OF OBSTACLE, AND PARKING ASSIST METHOD AND SYSTEM

摘要

The present invention relates to a method of determining a position of an obstacle, an apparatus of determining a position of an obstacle, a parking assist method, and a parking assist system, and more particularly, to a technology of determining a position of an obstacle by comparing propagation distances a direct signal and an indirect signal.

主权项

1. An apparatus of determining a position of an obstacle, the apparatus comprising:
at least two sensors configured to transmit signals at different positions and receive reflected signals when the transmitting signals are reflected from an obstacle; an propagation distance calculation unit configured to calculate an propagation distance of a direct signal which is sent from a first sensor which is one of the at least two sensors and received by the first sensor, and an propagation distance of an indirect signal which is sent from a second sensor which is different from the first sensor among the two more sensors and received by the first sensor; and a position determining unit configured to determine a position of the obstacle by comparing the propagation distance of the direct signal and the propagation distance of the indirect signal, based on a result calculated by the propagation distance calculation unit.
