  • Patent number: 12174028
    Abstract: A parking assistance device includes an obstacle detection unit configured to detect an obstacle around a vehicle, a boundary detection unit configured to detect a boundary of a parking section, and a target position determination unit configured to determine a target position of a movement route of the vehicle based on the detected boundary. The target position determination unit recognizes, as a wheel stopper, the obstacle detected in a detection area that is set at a position in the parking section on a back side of an entrance and exit of the parking section based on the detected boundary, regardless of a height of the obstacle.

  • Publication number: 20240336283
    Abstract: A vehicle automatically gets out of a parking area toward a location required by an user. A relative position between a communication terminal carried by the user and the vehicle is determined according to one of detection processes corresponding to a communication state between the communication terminal and one or more of sensor units on the vehicle. An out-of-parking target position is set based on a detection result of the position detection, and an optimum out-of-parking target position is calculated by updating the out-of-parking target position when the position detection has a higher reliability than the currently set out-of-parking target position while getting out of the parking area. An autonomous driving operation of the vehicle is controlled to get out of the parking area toward the out-of-parking target position.

  • Publication number: 20240262345
    Abstract: A park assist device having a route setting unit setting a parking route including a forward parking route from a current position of the vehicle to a forward travel stop position and a steering wheel turning parking route in reverse from the forward travel stop position to guide the vehicle forward after reversing, to park the vehicle in a forward travel attitude into a parking space. The device includes a guidance controller guiding the vehicle along the parking route. The route setting unit sets a distance between the vehicle stopped at the forward travel stop position and an entry-side end of the vehicle into the parking space, and sets the forward travel stop position to a position that allows the vehicle to be guided and parked in the forward travel attitude space after the guiding the vehicle in reverse by turning with a steering angle determined according to the distance.

  • Patent number: 11904840
    Abstract: A parking assistance device includes: a calculation unit that calculates a target speed with passage of time until a vehicle is moved to a parking target position; an event detection unit that detects an event that is a predetermined event indicating a timing of recalculation of the target speed; and an acquisition unit that acquires a current actual speed of the vehicle. Then, when the event is detected, the calculation unit recalculates the target speed to match the target speed with the current actual speed of the vehicle.
