OBJECT DETECTION DEVICE

摘要

An object detection device mounted on a vehicle includes a transmitter, a receiver, a measurement unit, and a determination unit. The transmitter intermittently transmits a signal wave to space around the vehicle. The receiver receives a reflected wave from an object. The measurement unit measures a distance to the object based on the reflected wave received by the receiver. The determination unit determines that the object is abnormally close to the vehicle if the distance measured by the measurement unit is within a determination distance range, counts the number of determinations that the object is abnormally close to the vehicle, and determines that at least one of the transmitter or the receiver malfunctions if the number of determinations reaches a threshold.
