  • Patent number: 11919442
    Abstract: A vehicle interior lighting device includes a light source which is installed at an end of an instrument panel of a vehicle. Light emitted from the light source propagates from the instrument panel toward a door panel, and is projected on a surface of a door trim of the door panel. A decorative pattern element is installed on a light emitting side of the light source. As light from the light source passes through the decorative pattern element, the light can create a pattern on a surface of the door trim. Because the light source is installed on the instrument panel spaced from the door trim rather than on the door trim itself, light can be projected on a large area of the door trim. Furthermore, an impressive feature of a decorative pattern which changes in accordance with a door opening angle can be achieved.

  • Patent number: 11920936
    Abstract: A vehicle controller determines whether the position of a detected travel lane relative to an edge of a road being traveled by a vehicle may differ from an actual position; estimates a first required time for an action, which is required before the vehicle reaches a predetermined location, for the case that the position of the detected lane relative to the edge of the road is correct; estimates a second required time for the action for the case that the position of the detected lane differs from the actual position by a predetermined number of lanes; and sets start timing of the action, based on the second required time, so that the action will finish before the vehicle reaches the predetermined location, when the position of the detected lane may differ from the actual position and the second required time is longer than the first required time.

  • Patent number: 11919509
    Abstract: Disclosed is a driving assist apparatus which executes a process for collision avoidance when the possibility of collision of a vehicle with an obstacle is high. When the steering angle of the steering wheel is greater than an angle threshold, the apparatus determines that a driver is trying to avoid the collision by operating the steering wheel and does not execute the collision avoidance process. When the vehicle is making a right turn or a left turn, there arises a possibility that the collision avoidance process is not executed even in a situation where the collision avoidance process must be executed. In view of this, when the vehicle is making a right turn or a left turn, the angle threshold mentioned above is set to a larger value as compared with the case where the vehicle is not making a right turn or a left turn.
