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.

Object detection device

An object detection device includes a controller, a first sensor, and a second sensor. The first sensor transmits a first energy wave, and the second sensor transmits a second energy wave. The first sensor receives a reflected wave of the first energy wave to convert the reflected wave into a first self-signal, and receives a reflected wave of the second energy wave to convert the reflected wave into a first correspondence signal. The second sensor receives the reflected wave of the second energy wave to convert the reflected wave into a second self-signal, and receives the reflected wave of the first energy wave to convert the reflected wave into a second correspondence signal.

Object detection device and object detection method

An in-vehicle monitoring system is configured to determine the presence of an object when the number of continuous generations of an object detection signal obtained in connection with a transmission signal reaches a threshold. The in-vehicle monitoring system comprises an adjustment unit configured to decrease the threshold if the distance obtained from a transmission signal and an object detection signal decreases.
