  • Patent number: 11872982
    Abstract: A parking assistance device performs parking assistance control including steering angle control for changing a steering angle of a vehicle, driving force control for controlling a driving force of the vehicle, and braking force control for controlling a braking force of the vehicle. The parking assistance device notifies an occupant of a driving operation to be performed by the occupant, including a moving operation on a shift lever and an operation on a brake pedal when the vehicle reaches a switching position where a traveling direction of the vehicle is to be switched during performing the parking assistance control. When the driving operation is performed by the occupant, the parking assistance device restarts the parking assistance control at a timing when the occupant stops the operation on the brake pedal.

  • Patent number: 11613196
    Abstract: When it is confirmed that a user exists based on an image of the situation outside a vehicle which is captured using a camera and a proximity sensor detects a fact that the user is approaching based on, for example, a putting of a hand of the user over the proximity sensor, a control device causes a ramp to be extended. As such, a user sitting in a wheelchair can cause the ramp to be extended by approaching the proximity sensor, such as the putting of the user's hand over the proximity sensor such that the user sitting in the wheelchair does not have to press an extension/storage button provided on the vehicle to cause the ramp to be extended.

  • Patent number: 11518312
    Abstract: A step device for a vehicle includes a movable step and a coupling member. The movable step includes a guide rail. The coupling member is configured to cause the movable step to move from a deployed position to a retracted position as a engaging part comes into sliding contact with a side wall of the guide rail that is located on an inner side in a vehicle width direction and, while pressing the side wall, moves inside the guide rail in a direction of closing a sliding door. The guide rail is configured such that a terminal end region on a closing side including a terminal end position at which the engaging part is located when the sliding door is fully closed constitutes a closing-side free running zone in which the engaging part does not press either of the side walls.

  • Patent number: 11433746
    Abstract: A protrusion is formed on a first part of an inner-cabin side wall of an installation base member of a protector with a sensor. The first part is closer to a connecting wall than a second part opposite the first part. The protrusion is on a virtual line in cross section. The virtual line is where convex substances, keys for example, hanging on passengers' clothes conceivably pass through. The virtual line extends toward a connecting point from a rear part of an automobile body closer to an interior of the automobile body than a reference line. The reference line is parallel with a direction in which a flange protrudes and extends from the connecting point. The connecting point is a part of an inner-cabin side end of a hollow part closest to an interior of the automobile body. The inner-cabin side end is connected with the installation base member.
