摘要:
There is provided a road configuration estimation apparatus that precludes influences of erroneous detection of an object and erroneous still determination and estimates a road configuration.A radar (peripheral object observation device) 110 repeatedly observes a relative position of an object relative to the moving object, which is located in the vicinity of a moving object. A stationary object identification unit (stationary object determination unit) 130 determines whether or not the object the relative positions of which have been observed by the radar 110 is still. A road approximate curve temporary computation unit (object correlation unit) 140 determines a plurality of the relative positions of an identical object observed by the radar 110 from among the relative positions observed by the radar 110. A road approximate curve main computation unit (approximate curve computation unit) 160 computes an approximate curve that approximates the configuration of a road on which the moving object is located, based on a result of the determination by the stationary object identification unit 130 and a result of the determination by the road approximate curve computation unit 140.

An angular velocity estimation apparatus of the invention is provided to estimate the angular velocity of a moving object with good accuracy.A peripheral object observation device (radar) 811 repeatedly observes a relative position of an object relative to the moving object, located in the vicinity of the moving object. A relative position acquisition unit 211 obtains a result of the observation by the peripheral object observation device 811. A stationary object determination unit (stationary object identification unit) 220 determines whether or not the object the relative position of which have been observed by the peripheral object observation device 811 is still. An object correlation unit (stationary object tracking unit) 230 determines a plurality of the relative positions of an identical object observed by the peripheral object observation device 811, from among the relative positions observed by the peripheral object observation device 811. An angular velocity estimation unit (state estimation unit 240, trajectory estimation unit) estimates the angular velocity of the moving object.

A radar device includes: a signal processor that receives an FMCW signal, detects a peak of a beat signal according to a reception signal and a transmission signal, and performs a correspondence of the beat frequency and an angle measurement process to generate target information; a beat frequency tracking filter that receives the beat frequency and updates a position and a velocity of the target; a pair observation value tracking filter that receives the observation value of the position and the velocity of the target to update the position and the velocity of the target; an integration/selection unit that integrates the tracks of both the tracking filters together or selects one thereof; a system track memory; and an abnormal value determination unit.
