A vehicle presentation control device, which is usable in a vehicle capable of performing autonomous driving, includes a processor. The processor distinguishably specifies, as an autonomous driving start requirement to be satisfied for a start of autonomous driving without monitoring obligation, at least a driver requirement, which is a requirement highly likely to be solved by a driver, or an environmental requirement, which is a requirement less likely to be solved by the driver. The processor starts, as requirement presentation that presents information about requirement necessary for the start of autonomous driving, driver requirement presentation, which indicates that the driver requirement is necessary for the start of autonomous driving, before the start of autonomous driving, in response to the specified autonomous driving start requirement being the driver requirement.

Vehicle presentation control device, vehicle presentation control system, and vehicle presentation control method

A vehicle information provision device may be mounted on a vehicle and provide information. The vehicle information provision device may output at least one sound information item out of a plurality of sound information items. The vehicle information provision device may determine whether the plurality of sound information items related to the vehicle are necessary to be provided.

Vehicle information provision device and vehicle information provision system

A display system that includes a liquid crystal element, a backlight, an adjustment unit, a light source control unit, and a liquid crystal control unit. The light source control unit operates the backlight to change a light source luminance level of light. The liquid crystal control unit operates a first plurality of pixels of the liquid crystal element to display normal information with a normal tone level. The liquid crystal control unit operates a second plurality of pixels of the liquid crystal element to display emphasis information with an emphasis tone level. When an adjustment value changes within a predetermined changeable range, the luminance level gradually changes with a change of the adjustment value, the normal tone level gradually changes with the change of the adjustment value, and simultaneously the emphasis tone level is maintained to correspond to brightness equal to or greater than brightness of the normal tone level.

Display system

A circuit board includes: a substrate; a conductive pattern disposed on a surface of the substrate; a lower insulation layer disposed on the conductive pattern to cover the conductive pattern except for an opening, through which the conductive pattern is partially exposed from the lower insulation layer; a conductor disposed on the lower insulation layer and connecting to the conductive pattern through the opening; an upper insulation layer disposed on the conductor for covering the conductor and the lower insulation layer; and a test coupon disposed on the substrate for evaluating the conductor.
