An electronic device, in disclosed embodiments, includes an antenna, transceiver circuitry coupled to the antenna, a memory configured to store a first operation key and instructions, and a processor coupled to the transceiver and to the memory. The processor is configured to execute the instructions stored in the memory to cause the electronic device to, in response to receiving a first transmission containing an encrypted version of a second operation key that is encrypted by the first operation key, decrypt the encrypted version of the second operation key using the first operation key to recover the second operation key, store the second operation key in the memory, transmitting, by a transmitter of the electronic device, a second transmission that contains the first operation key and a command.

A vehicle has multiple alternative driving positions, with one or more visual displays assigned to each driving position for depicting content required to drive the vehicle. A selection device identifies a vehicle occupant as a driver, determines a location of the driver within the vehicle, and designates as the active driving position whichever of the alternative driving positions the driver occupies. A processing unit transfers video relevant to vehicle operation to one or more of the displays visible from the active driving position and enables control of the vehicle from the active driving position. The selection device may also check whether the vehicle occupant meets one or more conditions required to be designated as the vehicle driver, and may determine an identity associated with the driver so that the displayed video is customized or personalized in accordance with that identity.

A transparent display for a vehicle that includes a self-emissive display with an electronically adjustable brightness and a masking display with an electronically adjustable absorption. The masking display is arranged back-to-back with the self-emissive display. At least one light sensor that is arranged in proximity to the masking display. A display controller is connected to the self-emissive display, to the masking display and to the at least one light sensor. The display controller is operative to adapt an absorption of the masking display in response to a signal of the at least one light sensor.

A dustproof cover having a reduced size in a depth direction is formed. In displaying a virtual image visible to a driver by reflecting projection light projected in front of a driver on a windshield (light-transmitting member), a dustproof cover provided in a path of the projection light to close an opening includes a recessed surface provided throughout a front and rear direction of a vehicle, and a cylindrical surface provided such that the recessed surface is continuous throughout a right and left direction of the vehicle. Curvatures of the recessed surface are configured to increase toward a front side of the vehicle, and therefore outer light entering the opening from a position above the vehicle is reflected in a direction invisible to the driver.

A key fob device, in one embodiment, includes a transceiver that receives and sends signals, a memory that stores a public key and a certificate of authenticity associated with the key fob device, and a processor coupled to the transceiver and memory. The processor is configured to execute instructions causing the key fob device to transmit the public key and the certificate of authenticity, execute a public key agreement protocol to generate a common secret encryption key, and receive an operation key encrypted with the common secret encryption key.

Apparatuses, computer programs and methods are provided. A method includes causing display on an autonomous or semi-autonomous vehicle of a dynamic sign acknowledging the presence of at least one road user.

A calling device for calling and communicating with a driver of a vehicle with a low power by using a Low Power Wide Area Network (LPWAN) such as a LoRa communication network and a calling method thereof are disclosed. The calling device according to the invention may be installed in a vehicle and transmit/receive data to/from a management server through the LPWAN. The calling device transmits a calling message to a driver terminal by recognizing a user's tapping, touching, etc., and when the driver confirms the calling message, display to the caller that the driver confirms the calling message. In addition, the calling device also allows the caller to call the driver directly by displaying the driver phone number if the driver does not confirm the calling message in time.

A steering input apparatus for a vehicle includes a grip position sensor configured to sense a grip position on a rim of a steering wheel of the vehicle. The steering input apparatus also includes at least one processor configured to, based on a determination that the grip position on the rim of the steering wheel sensed through the grip position sensor is improper for a driving situation of the vehicle, perform a control operation to output grip guide information for the rim of the steering wheel.

A display device includes a flexible member having a light-transmissive property, a plurality of first light sources disposed on a side of a first surface of the flexible member, the first light sources outputting light toward the flexible member, a skin disposed on a side of a second surface of the flexible member opposite from the first surface, the skin including a plurality of first transmission areas that transmit the light output from the plurality of first light sources and passing through the flexible member as light representing shapes of a plurality of first symbols in plan view, and a first light-shielding wall at least part of which is disposed in the flexible member, the first light-shielding wall separating a plurality of first optical paths extending from the plurality of first light sources to the plurality of first transmission areas.

A vehicle includes a vehicle body having a cabin, a first seat and a second seat arranged in the cabin, a planar transparent member placed on a side surface of the cabin, and that separates an interior of the cabin and a vehicle exterior from each other, and a display device placed on the side surface of the cabin and arranged along the planar transparent member, the display device having a plurality of pixels, wherein there is a case where information can be provided by a display of the plurality of pixels passing through decorative sheet by the display device lighting on, and there is a case of hiding the plurality of pixels by the display device lighting off
