  • Publication number: 20230249677
    Abstract: A parking assist system includes an environment information obtainer and a parking assist controller. The parking assist controller includes an available parking space detector, a target guiding route setter, a target stop position setter, and a steering controller. The steering controller turns a steered wheel of a vehicle and fixes the steered wheel to a steering angle at which the vehicle starts to be reversed at a target stop position for turning the vehicle along a target guiding route. The steering controller also turns the steered wheel to a steering angle at which the vehicle starts to be reversed to an available parking space at a target stop position for parking the vehicle in a state in which the vehicle is in line with the available parking space.

  • Patent number: 11688279
    Abstract: A mobility information provision system includes a collector, a mapping unit, a generator, and a controller. The collector collects information about movement of mobile bodies. The mapping unit maps positions of the mobile bodies on the basis of the information collected by the collector. The generator generates course-related information by using information including the positions of the mobile bodies mapped by the mapping unit. The controller controls movement of each of the mobile bodies, by using the generated course-related information, or information obtained on the basis of the course-related information and usable for determination or control of the movement of the corresponding one of the mobile bodies. The generator generates the course-related information for each of the mobile bodies, to prevent hindrance to movement of a first mobile body moving in emergency, out of the mobile bodies.

  • Patent number: 11505191
    Abstract: The steering controller calculates a target steering angle for causing the own vehicle to travel along the target course acquired by the traveling road information acquirer. The braking/driving force controller calculates a target yaw moment for correcting the positional displacement of the own vehicle from the target course. The control ratio setter sets a control ratio of cooperative control of steering control and yaw moment control based on the deviation amount of a lateral position of the own vehicle from the target course. The control ratio is set so that when the positional displacement of the own vehicle from the target course is relatively small, the ratio at which the steering control occupies is reduced, and the yaw moment control is dominant, and when the positional displacement of the own vehicle from the target course is relatively large, the ratio at which the steering control occupies is increased.

  • Publication number: 20220256082
    Abstract: A traveling environment recognition apparatus includes a camera, a first traveling environment recognition unit, a second traveling environment recognition unit, and an imaging mode switching unit. The first traveling environment recognition unit calculates the movement amount of a vehicle on the basis of an optical flow in an image captured by the camera. The second traveling environment recognition unit calculates a vehicle position in the real space on the basis of positioning signals received from positioning satellites. The imaging mode switching unit drives the camera in a first imaging mode when positioning accuracy based on the positioning signals is high, while the imaging mode switching unit drives in a second imaging mode when the positioning accuracy is low. When the camera is driven in the second imaging mode, the second traveling environment recognition unit estimates the vehicle position on a road map based on the movement amount.
