Object recognition device for vehicle

摘要

An object recognition device includes a radar unit, a recognition range setting means, a recognition means, a speed detection means, and a recognition range switching means. The radar unit is for emitting transmission waves in a plurality of angular ranges within a recognition range set from the plurality of angular ranges and for receiving reflected transmission waves from a reflecting object. The recognition range setting means sets the recognition range and instructs the radar unit to emit the transmission waves. The recognition means recognizes the reflecting object based on a result of emission and receipt of waves by the radar unit. The speed detection means detects a vehicle speed. The recognition range switching means switches the recognition range to a new recognition range when the detected speed is smaller than a predetermined speed.
