Abstract: A locking and unlocking system includes a controller. The controller is configured to acquire a state of locking and unlocking of a vehicle that is locked and unlocked based on locking and unlocking instruction information acquired from a portable terminal, and send a notification to a first device associated with the vehicle, when the vehicle is not locked during a period of time from when the vehicle is unlocked based on the locking and unlocking instruction information acquired from the portable terminal until a first timing.

Abstract: A display device for a vehicle includes: a first image control section that displays a first entire image in a certain entire display region; a second image control section that displays a second entire image that is changed from the first entire image in the certain entire display region; and an intermediate image control section that displays a single intermediate entire image indicating an intermediate stage of a change between the first entire image and the second entire image in the certain entire display region. The second image control section displays a final display state in which a certain mark is displayed in a certain portion within the certain display region as the second entire image. The intermediate image control section displays the intermediate entire image having an afterimage of the certain mark being extended in a track direction on a track of the certain mark moving to the certain portion.

Abstract: A vehicle interior display system includes: a display device that projects projection light of projection information, and displays the projection information in at least one display region arranged at a position that is visible from the inside of a vehicle compartment; and a control device that controls the display device, and causes the display device to project the projection light. A dimming film that varies light transmittance depending on a voltage value of applied voltage is arranged in the display region or a projection region of a transmitting member for the projection light that is present ahead of a line of sight of an occupant who directs toward the display region in the vehicle compartment.

Abstract: A vehicle display device includes a tubular member disposed such that an opening edge thereof faces a driver side, a projection unit that projects light toward an inner space of the tubular member, a semitransparent mirror that is disposed in the inner space of the tubular member and reflects light projected from the projection unit toward the driver side to cause a virtual image to be displayed, an image display unit that is disposed on a side opposite to the driver side with respect to the semitransparent mirror in the tubular member and displays an image, and a design unit that is disposed between the image display unit and the semitransparent mirror in the inner space of the tubular member and has a stereoscopic shape.
