Abstract
An obstacle sensor includes: a supersonic sensor for detecting an obstacle in a first range, the supersonic sensor including a substrate, a transmission device and a reception device disposed on the substrate; a detection element for detecting the obstacle in a second range; and a case. The reception device includes multiple reception elements. At least a part of the first range of the supersonic sensor is different from the second range of the detection element. The supersonic sensor and the detection element are disposed in the case.
Claims18
An obstacle sensor for detecting an obstacle comprising:
- a supersonic sensor for detecting the obstacle in a first range, wherein the supersonic sensor includes a semiconductor substrate, a transmission device for transmitting a supersonic wave by converting an electric signal, and a reception device for receiving the supersonic wave and for converting the supersonic wave to an electric signal, and wherein the transmission device and the reception device are disposed on the substrate;
- a detection element for detecting the obstacle in a second range;
- and
- a case, wherein
- the reception device includes multiple reception elements,
- at least a part of the first range of the supersonic sensor is different from the second range of the detection element,
- the supersonic sensor and the detection element are disposed in the case, and
