Abstract: A control device for a vehicular illumination is configured to make definition of factors of an illumination control operation with a higher priority unnecessary when definition of factors of the illumination control operation with the higher priority is the same as definition of factors of an illumination control operation with a lower priority than the illumination control operation with a higher priority.

Abstract: A vehicle is a vehicle that is equipped with an illumination device in a vehicle cabin and that is capable of traveling in an EV mode, the vehicle being configured to change a manner of luminescence of the illumination device when the vehicle enters a low emission zone (LEZ) where the vehicle needs to travel in the EV mode, and to cause a driver to perceive the entrance. For the change in the manner of the luminescence, for example, the color of the luminescence of the illumination device may be changed from a regular color to a specific color. By the change in the manner of the luminescence of the illumination device, it is possible to cause the driver to sensorily recognize the entrance to the low emission zone.

Abstract: An onboard relay device comprises memory and a processor connected to the memory. The processor is configured to receive a data transmission request from a request originator, determine whether received data that is data received from a transmission originator is variable data or fixed data, record the received data in a cache memory section temporarily in cases in which the received data is the fixed data, determine whether or not transmission request data that is data subject to a transmission request from the request originator is recorded in the cache memory section, and in cases in which the processor has determined the transmission request data to be the received data recorded in the cache memory section, transmit the received data recorded in the cache memory section to the request originator as the transmission request data.

Abstract: A navigation device includes a processor. The processor collects captured images that have been captured by an imaging device mounted at a vehicle, sets a destination, and determines a route to the destination based on the captured images that have been collected.
