    • 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 (6) that: emits detection light (3) at prescribed intervals from a light-emitting unit (2) on an exterior panel of a vehicle towards a detection region (1) set outside said vehicle; tests for a threshold-exceeded state in which the amount of light in a light reflection (4) received from the detection region (1) by a light-receiving unit (5) exceeds a prescribed detection threshold; and, if it is detected that a detection target has entered the detection region (1), outputs a detection-confirmation signal. The control unit (6) 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 (4) preceding the light reflection (4) on which the comparison is being performed.
    • 本发明的目的是提供一种具有改进的控制可靠性的车辆反射光学传感器。 所述车辆用反射型光传感器具备:控制部(6),其从车辆的外板上的发光部(2)以规定的间隔向设定在外部的检测区域(1)照射检测光(3) 所述车辆; 测试光接收单元(5)从检测区域(1)接收到的光反射(4)中的光量超过规定的检测阈值的阈值超出状态; 并且如果检测到检测目标已经进入检测区域(1),则输出检测确认信号。 控制单元(6)使用作为上述检测阈值的预定的固定值和包括光反射之前适当数量的光反射(4)中的光量的汇总统计量的调整值的总和(4) )正在进行比较。
