Abstract: In a target track generation apparatus, a subject vehicle reference preceding vehicle position calculator calculates a point group of subject vehicle reference preceding vehicle positions representing a history of a relative position of a preceding vehicle in a coordinate system using a current position of a subject vehicle as a reference. A target track generator generates a target track of the subject vehicle, based on the point group of the subject vehicle reference preceding vehicle positions. A correction target track generator generates a correction target track obtained by correcting the target track, based on the point group of the subject vehicle reference preceding vehicle positions or the target track, when it is determined that correction of the target track is necessary.

Abstract: In a target track generation apparatus (10), a preceding vehicle position acquisition unit (1) acquires a relative position of a preceding vehicle. A subject vehicle state quantity acquisition unit (2) acquires a state quantity of a subject vehicle. A subject vehicle movement amount calculator (3) calculates a movement amount of the subject vehicle, based on the state quantity of the subject vehicle. A subject vehicle reference preceding vehicle position calculator (4) calculates a point group of subject vehicle reference preceding vehicle positions representing a history of the relative position of the preceding vehicle in a coordinate system using a current position of the subject vehicle as a reference, based on the relative position of the preceding vehicle and the movement amount of the subject vehicle. A target track generator (5) generates a target track of the subject vehicle, based on the point group of the subject vehicle reference preceding vehicle positions.

Abstract: A coordinate obtaining unit of an automatic steering control apparatus obtains a subject-vehicle coordinate point indicating a current position of a subject vehicle, and a target coordinate point indicating a target position of the subject vehicle. A subject-vehicle state quantity obtaining unit obtains a subject-vehicle state quantity indicating a traveling state of the subject vehicle. A target trajectory determining unit calculates an interpolation coordinate point for interpolating between the subject-vehicle coordinate point and the target coordinate point or between a target coordinate point previously obtained and a target coordinate point subsequently obtained, and determines a target trajectory of the subject vehicle based on the interpolation coordinate point. A steering controller controls a steering control device of the subject vehicle so that the subject vehicle travels following the target trajectory, based on the subject-vehicle state quantity and the target trajectory.
