  • Patent number: 11912272
    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.

  • Publication number: 20220135080
    Abstract: An object of the present disclosure is to accurately forced stop autonomous vehicle control when a failure occurs in a remote control terminal without mounting an additional sensor on a vehicle. The vehicle control device includes the detection unit that detects a forced stop operation, a control unit that implements the autonomous parking control of the vehicle, and a calculation unit that causes the control unit to perform the autonomous parking control when the start command is received from the remote control terminal, and causes the control unit to stop the autonomous parking control when the stop command is received from the remote control terminal. When the detection unit detects the forced stop operation while the control unit is performing the autonomous parking control, the calculation unit causes the control unit to stop the autonomous parking control even without receiving the stop command from the remote control terminal.

  • Patent number: 11285946
    Abstract: Provided is a moving object detector capable of acquiring a position history of a moving object that is less affected by the behavior of a subject vehicle. In a moving object detector, a moving-object relative position acquiring unit acquires position coordinates of a moving object expressed in a subject-vehicle-based coordinate system that is based on the position of a subject vehicle. A subject-vehicle state quantity acquiring unit acquires the state quantity of the subject vehicle. A coordinate converter generates a history of position coordinates of the moving object expressed in a moving-object-based coordinate system that is based on the position of the moving object, on the basis of the position coordinates of the moving object expressed in the subject-vehicle-based coordinate system, and the state quantity of the subject vehicle.

  • Publication number: 20210394755
    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.

  • Patent number: 10549776
    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.
