A display panel is employed in a vehicle equipped with an external situation recognizing device that is configured to receive electromagnetic waves from outside to recognize an external situation. The external situation recognizing device is located at an end in a front-rear direction of the vehicle. The display panel is provided at the end of the vehicle and extends in a direction intersecting with the front-rear direction of the vehicle. The display panel includes a display unit and a cover unit that is closer to an outside of the vehicle than the external situation recognizing device and is located at a position that corresponds to the external situation recognizing device. The cover unit is configured to allow the external situation recognizing device to receive the electromagnetic waves from outside through the cover unit. The display unit is located to be adjacent to the cover unit.

A vehicle position guidance system includes a terminal position measurement section, a vehicle position measurement section, a calculator, and a guide. The terminal position measurement section measures a position of a terminal carried by a user. The vehicle position measurement section measures a position of a parked vehicle. The calculator obtains a route using position information related to the terminal and position information related to the parked vehicle. The guide assists the user in entering the vehicle by selectively using a first guidance and a second guidance depending on whether a distance is long or short between the terminal and the parked vehicle on the route. The first guidance provides guidance to the position of the parked vehicle using the terminal. The second guidance provides guidance to the position of the parked vehicle through a notification using a vehicle on-board device of the parked vehicle.

An LED-driving device includes a displaying section including a plurality of displaying groups, each composed of a plurality of connected LED elements, each with a built-in light emission-controlling element, a power-supplying section configured to provide a supply of an electric power to the displaying section, switching sections configured to selectively make or break connections between the power-supplying section and those displaying groups respectively, and a controlling section configured to make a decision as to whether, when the power-supplying section is powered on, an output value from the power-supplying section is normal or not, and as a result of determining that the output value from the power-supplying section is normal, perform such a control of the connections between the power-supplying section and those displaying groups as to enable the switching sections to in turn connect supplies of the electric power from the power-supplying section to those displaying groups, respectively.

A vehicle sensor unit includes a millimeter wave radar device, an infrared sensor that is arranged at a position adjacent to the millimeter wave radar device, and a cover having a first cover portion and a second cover portion. The first cover portion is located in front of the millimeter wave radar device in a transmission direction of the millimeter waves to conceal the millimeter wave radar device and has millimeter wave transparency. The second cover portion is located in front of the infrared sensor in a transmission direction of the infrared light to conceal the infrared sensor and has infrared light transparency. The millimeter wave radar device and the infrared sensor are attached to the cover so that the whole vehicle sensor unit is configured as a single unit.

An onboard sensor cover includes a cover body that includes front and rear bases and a decorative layer. The front base is made of a transparent plastic material that permits passage of an infrared ray and a millimeter wave and includes a rear surface in the transmission directions of the infrared ray and the millimeter wave that is configured by a first uneven surface. The rear base is made of a plastic material that permits passage of the infrared ray and the millimeter wave and includes a front surface in the transmission directions that is configured by a second uneven surface. The decorative layer is made of a material that reflects visible light and permits passage of the infrared ray and the millimeter wave and is in contact with the first and second uneven surfaces. The front and rear bases are made of the same type of plastic material.
