  • Publication number: 20220250611
    Abstract: A parking assist device capable of parking assistance that ensures high accuracy of a parking location is provided. A parking assist device that assists in performing an operation of parking a vehicle includes a parking-allowing location calculation unit that before the vehicle stops at a parking-allowing location, calculates and updates the parking-allowing location a plurality of times, and a parking route calculation unit that calculates a parking route. The parking route calculation unit sets a minimum turning radius for calculating the parking route, based on the amount of a shift between the parking-allowing location not updated and the parking-allowing location having been updated, and calculates the parking route, using the minimum turning radius. The minimum turning radius is set larger than the minimum value of a turning radius unique to the vehicle.

  • Patent number: 11332126
    Abstract: When one sensors fails and thus malfunctions during automatic parking of a vehicle, only the other sensor functions. Accordingly, depending on the behavior of the vehicle, the detection characteristics of the other sensor cause degradation in recognition of the vehicle, hindering the automatic parking from being continued. In processing S401, a determination is made whether or not an external recognition device, such as a camera or sonar, malfunctions. In processing S402, based on the determination on malfunction of the external recognition device, a determination is made whether or not to restrict vehicle speed or to restrict a path, with reference to restriction information for parking control. The restriction information for parking control provides information for restricting the vehicle speed in accordance with the malfunction of the camera, and for restricting the path in accordance with the malfunction of the sonar.

  • Patent number: 11230284
    Abstract: The present driving assistance apparatus assists driving from a vehicle stop state in a predetermined area. The apparatus acquires outside world information from the surroundings of a vehicle, detects a place and position to which the vehicle can move, detects a position of the vehicle, calculates a movement route when the vehicle moves in a predetermined direction by automatic driving from a vehicle stop state in a predetermined area, and determines a safety confirmation position at which the driver can visually confirm a surrounding traveling environment on the movement route. The route is calculated based on the outside world information and the position of vehicle. The driving assistance apparatus reduces a speed of the vehicle to a predetermined speed or less so that the driver can visually confirm the surrounding traveling environment at the safety confirmation position.
