Provided is an arithmetic processing to reduce a number of parts as it is not necessary to prepare an operation device for each input processing logic. A plurality of types of input processing logics is stored in the ROM, and CPU selects one of the plurality of types of input processing logics and executes input processing according to the selected input processing logic. As a result, there is no need to prepare the ECU for each input processing logic, reducing the number of parts.

Arithmetic unit

An in-vehicle production lighting system includes: an acceleration sensor configured to detect an acceleration of a vehicle; light emitters arranged at a prescribed position in a cabin of the vehicle and capable of changing light intensity and light color in a prescribed lighting pattern; and a controller configured to generate or select the prescribed lighting pattern depending on a detection result obtained by the acceleration sensor and control the light emitters.

In-vehicle production lighting system

A lighting device which can produce various fade operations without significantly consuming memory capacity is provided. Duty ratios for a plurality of steps are recorded in a ROM of a slave ECU. The slave ECU sets an interval time for 1 step, reads out from a map brightness of a next step at each set interval time, and outputs a pulse with the read out duty ratio to a LED. A change duty ratio, a pre-change interval time and a post-change interval time are recorded in the ROM. The slave ECU sets the interval time for 1 step to the pre-change interval time before the duty ratio of the LED reaches to the change duty ratio, and changes the setting by setting the interval time for 1 step to the post-change interval time after the duty ratio of the LED has reached to the change duty ratio.

Lighting device

A vehicle interior lighting apparatus for illuminating the interior of a vehicle, being equipped with a plurality of light source units each having a light source emitting the three primary colors of light and a control connector for simultaneously controlling the on/off operations and the luminance levels of predetermined two colors in all the light source units and for individually controlling the on/off operation and the luminance level of one color other than the predetermined two colors in each of the light source units.

Vehicle interior lighting apparatus

A vehicle interior illumination device for controlling illumination in a vehicle interior includes an operation input portion configured to receive an instruction operation of either lighting or light adjustment by a user, a first state detection portion configured to detect a first state representative of a getting-off preparation of the user, a second state detection portion configured to detect a second state representative of a getting-off completion of the user, and a light adjustment degree setting portion configured to shift the illumination to a preset light adjustment degree including off when the first state and the second state are detected.

Vehicle interior illumination device

A vehicle interior lighting apparatus for illuminating the interior of a vehicle, being equipped with a first lighting section having a light source emitting light and a light guide plate emitting light by virtue of the light from the light source, wherein the first lighting section has a planar light emitting section emitting light emitted from the light source in a planar manner and a linear light emitting section integrated with the planar light emitting section and emitting light emitted from the light source linearly.

A vehicle interior illumination device includes: illumination parts respectively provided in a plurality of positions in a vehicle; and a control part which controls turning on and off operations and illuminating colors of the illumination parts. The control part allows the illumination parts respectively to emit lights by different colors of a same type relating to a theme selected by the control part.

An illumination control device includes a control portion which controls light emission states of luminous bodies and having different light emission colors from one another, so that a cabin is illuminated by emitted light emitted from a light source and having predetermined chromaticity. The light source has the luminous bodies. The control portion controls the light emission states of the luminous bodies in accordance with a correction coefficient inputted from outside to adjust the chromaticity of the emitted light.

Illumination control device

A lighting control system includes a plurality of light sources, a plurality of light source drivers, each of the light source drivers being configured to adjust a light emission intensity of an associated one of the light sources in at least two levels, and an integrated controller configured to control the light source drivers to control conditions of the light sources in an integrated manner. The integrated controller is configured to control the light source drivers to execute a light intensity transition of reducing the light emission intensity from a first light intensity level to a second light intensity level that is lower than the first light intensity level with respect to each of the light sources such that a timing at which the light intensity transition ends is substantially the same for each of the light sources.
