An object detection device includes an acquisition module and a detection module. The acquisition module acquires a detection distance indicating a distance from a transmission/reception unit mounted on a vehicle to an object and a reception intensity indicating an intensity of a reflected wave received by the transmission/reception unit. The detection distance is detected based on results of transmission of a transmission wave by the transmission/reception unit and reception of the reflected wave from the object by the transmission/reception unit. The detection module detects a detection target among objects including the object based on the reception intensity exceeding an intensity threshold. The detection module increases the intensity threshold when the detection distance is a distance threshold or less and the detection target is detected.

Object detection device

An object detection system includes: a plurality of object detection units. The object detection units each include a transmission and reception unit configured to transmit an ultrasonic wave and receive a reflected wave generated by reflection of the ultrasonic wave on an object, a reception circuit unit configured to detect a signal level of the reflected wave received by the transmission and reception unit, a detection unit configured to detect the object by comparing the signal level detected by the reception circuit unit with a predetermined signal threshold value, a temperature sensor configured to detect a temperature of an environment, and a detection sensitivity adjustment unit configured to adjust detection sensitivity of the reception circuit unit based on a second lowest temperature among temperatures detected by the respective temperature sensors in the plurality of object detection units.
