  • Publication number: 20160078766
    Abstract: A parking assist system includes an electronic control unit. The electronic control unit is configured to set at least one candidate position that is a candidate for a target position of a moving path of a vehicle on the basis of at least one of a detected obstacle or a detected parking boundary, rank each of the at least one candidate position on the basis of the candidate position and a position and orientation of the host vehicle, and determine one of the ranked at least one candidate position as the target position.

  • Publication number: 20160075376
    Abstract: A parking assist system includes an electronic control unit. The electronic control unit is configured to detect that a vehicle has moved through a switching position and reached a predetermined state during parking assist for the vehicle, and, when it is detected that the vehicle has reached the predetermined state, provide a notice that the vehicle has reached the predetermined state by imparting a predetermined vibration to a steering wheel of the vehicle.

  • Publication number: 20160077525
    Abstract: A control system for a vehicle includes an electronic control unit. The electronic control unit is configured to acquire first information indicating a situation of the vehicle at the time when the vehicle is traveling, and set a path for guiding the vehicle to a target position on the basis of the first information such that a variation in an inertial force in a lateral direction perpendicular to a traveling direction of the vehicle is smaller than or equal to a first threshold.

  • Publication number: 20160075329
    Abstract: A parking assist system includes an electronic control unit. The electronic control unit is configured to: at the time of assisting in parking a vehicle to a parking area, determine a path from an initial position of the vehicle to a target position; generate a first circumference that passes through the initial position and that touches a traveling direction of the vehicle, as the path; determine a center position on the basis of a position of a rear corner of a parked vehicle ahead, a turning radius of the vehicle at a minimum turn and the target position; and generate a second circumference that has a center at the center position and that passes through the target position and touches both the traveling direction of the vehicle at the target position and the first circumference, as the path continuous with the first circumference.

  • Publication number: 20160075377
    Abstract: A parking assist system for a vehicle including a display device that is arranged behind a steering wheel from a driver and that displays parking assist information and a driving unit that rotationally drives the steering wheel includes an electronic control unit. The electronic control unit is configured to detect that the vehicle has moved through a switching position and reached a predetermined state during parking assist, and, when it is detected that the vehicle has reached the predetermined state, control the driving unit to rotationally drive a rotation angle position of the steering wheel to a rotation angle position at which it is estimated that at least the parking assist information is visually recognizable by the driver.

  • Publication number: 20160068187
    Abstract: An electronic control unit assists parking of a host vehicle into a parking space. Ultrasonic sensors detect the shape of the side edge of a road and the presence of an obstacle at the road edge. The electronic control unit sets one corner of the obstacle positioned on the side opposite to the road side edge as an originating corner, sets an imaginary line that follows the shape of the road side edge and extends from the originating corner, and recognizes the space between the imaginary line and the road side edge as a parking space. The electronic control unit then determines whether the vehicle can be parked in the recognized parking space.

  • Patent number: 9266562
    Abstract: A parking assist device assists entry or exit of a vehicle with respect to a parking space through an automatic control of a steering device. The parking assist device includes: a calculator that obtains, to perform the automatic control of the steering device, a path for allowing the vehicle to enter or exit the parking space based on the parking space, calculates an amount of temperature rise of the steering device at the execution of the automatic control for allowing the vehicle to move along the obtained path, and calculates a predicted temperature of the steering device at the execution of the automatic control by adding the calculated amount of temperature rise to a current value of the temperature of the steering device; and a controller that inhibits the execution of the automatic control when the predicted temperature is equal to or higher than a determination value.

  • Publication number: 20150307090
    Abstract: A parking assistance device includes an obstacle detection unit configured to detect an obstacle around a vehicle, a parking point detection unit configured to detect a parking target point where the vehicle can be parked based on the result of the obstacle detection, and a parking assistance control unit configured to guide the vehicle from a parking start point to the parking target point according to a guidance route based on the result of the obstacle detection and the result of the parking target point detection in a case where a traveling of the vehicle is detected during a period of time from a time when the vehicle reaches the parking start point to a time when a shift range is changed, the parking assistance control unit does not execute the guidance of the vehicle.
