A vehicle dimmer control system includes a controller that adjusts the visible light transmissivity of dimming glass in each of multiple windows included in a vehicle. The controller uses dimming determination information, which is at least one of own vehicle state information indicating a state of the vehicle and own vehicle position information indicating a vehicle position, to determine whether to bring the windows into a permeable or impermeable state. Based on this dimming determination information, the controller selects a control target window from among the plurality of windows and controls the dimming glass of that window to be in the permeable state or the impermeable state.

A connector device includes a connector housing having a terminal accommodating chamber, a terminal configured to be accommodated in the terminal accommodating chamber, an electric wire configured to be connected to the terminal, a corrosion-proof material to be disposed at a position facing the terminal accommodated in the terminal accommodating chamber and a corrosion-proof target portion of the electric wire, and a corrosion-proof material support portion retaining the corrosion-proof material above the connector housing such that the corrosion-proof material can be moved toward the corrosion-proof target portion. A melting point of the corrosion-proof material is set to be lower than a melting point of a material forming the connector housing, and the corrosion-proof material is configured to be melted and then cured while covering the corrosion-proof target portion.

Connector device and wire harness manufacturing method

A wireless communication system and an in-vehicle system which can establish communication without manually inputting code information such as a pairing ID are provided. In the wireless communication system, when a long-pressing operation of a lamp switch is performed, a pairing ID required for establishing wireless communication with a mobile device is acquired from a wireless unit, and the pairing ID is converted to an optical signal and transmitted from a lamp. The mobile device receives the optical signal by an imaging unit and acquires the pairing ID to establish the wireless communication with the wireless unit.

Wireless communication system and in-vehicle system

An in-vehicle communication system including independent communication hub devices each incorporating a function of relaying communication and a function of controlling a communication path among a plurality of communication connectors, in which each of the communication hub devices includes an internal power supply unit configured to generate, based on input power supply power supplied from a main power supply on a vehicle side, stabilized power supply power necessary for operation of an internal circuit, and a backup power supply output unit configured to supply the input power supply power or the stabilized power supply power generated by the internal power supply unit to the other communication hub device as backup power, in which a backup power supply line is provided which connects the backup power supply output units of the plurality of communication hub devices.

In-vehicle communication system

A light emitting apparatus includes a plurality of full-color LED units. Constant current values of the constant current elements are set such that the plurality of full-color LED units come closer to a same chromaticity as compared with a case in which all the constant current elements of all the full-color LED units have a same constant current value. As a result, in at least one of the plurality of full-color LED units, at least one of the plurality of constant current elements is set to a constant current value different from that of the other constant current elements.

Light emitting apparatus and chromaticity variation correction method

One or more of a plurality of input ports (P-P) that allow input of a binary signal are allocated to a unique port, and the potential thereof is fixed to a ground potential, etc., using the electrical wires () of a wire harness. The potential of the remaining input ports in the initial state is set to a high potential using a pull-up circuit, etc., and a combination of the potential of the unique port and the potential of the remaining ports is associated with the ID value of the corresponding node. In order to share the remaining ports in the reading of the ID and the reading of a signal, the ID is established after a standby until a given time has elapsed without a change in the potential when the potential of the input ports is read.

Control device and control system

A control device including a CPU is provided. The CPU outputs a plurality of pulses each having a duty set independently to LED. The CPU creates a schedule in which on-timing and off-timing of the plurality of pluses are designated such that the on-timing or the off-timing of two or more of the plurality of pulses is respectively not close to each other based on the set duty and a duty of the pulse. Further, the CPU sets, in a timer for counting time, time from a time point where the timer finishes counting the time already set to on-timing or off-timing of a pulse to be first turned on or off after the time point in accordance with the schedule. The CPU turns on or off the pulse in accordance with the schedule when the timer finishes counting the set time.

Control device, illumination device, and program for control device

A vehicle display control device, when a steering wheel is at a steering angle position of a neutral position or the vicinity thereof, if a right hand sensor detects gripping of the steering wheel, turns off light sources of memory buttons and operation buttons that can be operated with a right hand, and if a left hand sensor detects the gripping, turns off a light source of air conditioning related buttons and hides touch buttons of a touch panel display that can be operated with a left hand. The vehicle display control device, if the right hand sensor does not detect the gripping, turns on the light sources of the memory buttons and the operation buttons, and if the left hand sensor does not detect the gripping, turns on the light source of the air conditioning related buttons and displays the touch buttons on the touch panel display.

Vehicle display control device

Two communication ECUs which can be disposed in different areas on a vehicle are equipped with respective communication relays which are connected to each other by an interarea connection unit. The functions of each of the communication relays are simplified and separated from the functions of a router. When receiving a signal, the communication relays outputs the signal to another, belonging to the same system as the communication line from which the signal has been received, of communication lines and to the router. The router controls a route of a signal to be transmitted between different systems of communication lines that are one of the communication lines and one of the communication lines. Since the communication relays are low in cost and can operate at high speed and the number of routers is decreased, the components cost can be lowered.
