Object detection device

Abstract

An object detection device includes, for example, a transmission unit that transmits a transmission wave, a reception unit that receives a reception wave that is the transmission wave reflected back from an object, a temperature sensor that measures ambient temperature in surroundings, a threshold time-limit setting unit that changes a time limit of time for detecting that a degree of vibration after transmission by the transmission unit falls below a reverberation threshold in accordance with the ambient temperature measured by the temperature sensor, and an object detection unit that detects an object present in the surroundings based on a reflected wave received by the reception unit in accordance with the time limit of the time for detecting that the degree of vibration after transmission set by the threshold time-limit setting unit falls below the reverberation threshold.
