1. An obstacle detecting system for a vehicle comprising:
- an obstacle detecting section configured to detect an obstacle by transmitting a transmitting wave and receiving a receiving wave, which is a reflection of the transmitting wave by the obstacle;
a distance calculating section configured to calculate a distance to the obstacle; and
a directivity control section configured to lower a directivity of the transmitting wave to a lower value, when the distance calculated by the distance calculating section is less than a predetermined reference distance than when the distance is greater than the predetermined reference distance.

Abstract
An obstacle detecting system for a vehicle detects an obstacle by transmitting a transmitting wave and receiving a receiving wave, which is a reflection of the transmitting wave by the obstacle. The system calculates a distance to the obstacle. The system varies directivity of the transmitting wave in accordance with the calculated distance. The directivity is lowered when the calculated distance is less than a predetermined reference distance, than when the calculated distance is greater than the predetermined reference distance.
