Abstract
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.
