SOUND WAVE SENSOR, CORRECTION VALUE SETTING DEVICE, AND DISTANCE DETECTING DEVICE

摘要

A sound wave sensor in a distance detecting system determines a presence or absence of a target object and a distance to the target object by receiving, with a preset sensitivity, a reflected wave obtained from a transmitted sound wave reflected by the target object. A correction value used to correct the sensitivity of the sound wave sensor is obtained from outside the sound wave sensor, and the sensitivity is corrected by using this correction value.

1. A sound wave sensor for detecting a distance to a target object by transmitting and receiving a sound wave, comprising:
a target object determinator configured to determine a presence or absence of the target object and the distance to the target object by receiving, with a preset sensitivity, a reflected wave obtained from the transmitted wave reflected by the target object, and a correction value obtainer configured to obtain a correction value used to correct a sensitivity of the sound wave sensor from outside the sound wave sensor and configured to correct the sensitivity by using the correction value.
