Abstract

The purpose of this invention is to provide a vehicular reflective optical sensor that has improved control reliability. Said vehicular reflective optical sensor is provided with a control unit () that: emits detection light () at prescribed intervals from a light-emitting unit () on an exterior panel of a vehicle towards a detection region () set outside said vehicle; tests for a threshold-exceeded state in which the amount of light in a light reflection () received from the detection region () by a light-receiving unit () exceeds a prescribed detection threshold; and, if it is detected that a detection target has entered the detection region (), outputs a detection-confirmation signal. The control unit () uses, as the aforementioned detection threshold, the sum of a predetermined fixed value and an adjustment value comprising a summary statistic for the amounts of light in an appropriate number of light reflections () preceding the light reflection () on which the comparison is being performed.
