OBJECT DETECTION DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To secure desired responsiveness while reducing a position detection error of an object.

SOLUTION: This object detection device 10 for a vehicle has: a radar device 15 transmitting an electromagnetic wave over a prescribed angle on the periphery of one'own vehicle at prescribed time intervals, and receiving a reflected wave of the electromagnetic wave from the object present on the periphery of the own vehicle; a relative state amount calculation part 32 calculating a relative state amount comprising a relative distance and a relative position between the own vehicle and the object based on the reflected wave; a relative speed calculation part 33 calculating a relative speed between the own vehicle and the object based on the relative state amount; a relative speed correction part 34 correcting the relative speed by a prescribed filter time constant; and a one'own vehicle track estimation part 31 predicting a travel track of the own vehicle based on a movement state of the own vehicle. The relative speed correction part 34 changes the filter time constant based a distance of the object to the travel track.
