Claim:
1. An object detection device configured to detect an object around a vehicle based on sound information around the vehicle, the device comprising: a sound collecting unit mounted on the vehicle; an analysis unit configured to perform frequency analysis on sound information collected by the sound collecting unit; and a detection unit configured to detect the object around the vehicle based on a frequency characteristic of the sound information analyzed by the analysis unit, wherein, based on a frequency characteristic of a warning sound generated from a warning device mounted on the vehicle, the detection unit is configured to perform object detection such that object detection using a predetermined frequency band when a sound pressure of the predetermined frequency band of the warning sound is high is more suppressed than object detection using the predetermined frequency band when a sound pressure of the predetermined frequency band of the warning sound is low, the warning sound generated from the warning device is capable of being intermittently generated, and the detection unit is configured to perform object detection by using all frequency bands of the frequency characteristic of the sound information analyzed by the analysis unit for a period of time during which the warning sound is not generated.
