  • Publication number: 20230122841
    Abstract: An autonomous driving system mounted on a vehicle determines a target path based on necessary information and performs vehicle travel control such that the vehicle follows the target path. A first coordinate system is a vehicle coordinate system at a first timing when the necessary information is acquired. A second coordinate system is a vehicle coordinate system at a second timing later than the first timing. The autonomous driving system calculates, based on the necessary information acquired at the first timing, a first target path defined in the first coordinate system. Then, the autonomous driving system corrects the first target path to a second target path defined in the second coordinate system by performing coordinate transformation from the first coordinate system to the second coordinate system. The autonomous driving system uses the second target path as the target path to perform the vehicle travel control.

  • Patent number: 10649454
    Abstract: An autonomous vehicle having a control unit that is configured to perform autonomous driving in which a steered angle of steered wheels is changed by a steering device so that a steering angle becomes a target steering angle for making the vehicle travel along a target trajectory, and to control the steering device so that a lane change is performed in a standard manner when the lane change is necessary. In a situation where the lane change is necessary and a steering operation is being performed by a driver, when a magnitude of an index value based on a parameter that changes according to the steering operation is smaller than a termination reference value, the control device does not terminate the autonomous driving and changes a target trajectory of the lane change according to the magnitude of the index value.

  • Patent number: 10427712
    Abstract: The automatic driving system comprises an electric power steering apparatus and a control apparatus that performs automatic steering control. The control apparatus is programmed to perform determining processing and coping processing. In the determining processing, it is determined whether the automatic driving system is working well or not working well, based on tracking condition of the target traveling route by the vehicle. The coping processing is processing to increase a degree with which the steering intervention by the driver is reflected to a control variable of the electric power steering apparatus when the automatic driving system is determined to be not working well.
