A hub-mountable wheel-rotation detector has an electromagnetic generator to convert rotational mechanical energy into electrical energy sufficient to recharge an internal rechargeable battery and power internal alarm and distance-tracking circuitry. The detector provides a combination of backup alarm and hubodometer functionality in a common device.

An increase in the execution period of light distribution control is inhibited by reducing the number of images required for the light distribution control while achieving both object detection and light distribution control function. The present invention has an object detection unit for performing an object detection process, a light point detection unit for performing a light point detection process, and a light distribution control unit for controlling the illumination state of headlights on the basis of the result of the object detection process and the result of the light point detection process.

Systems, methods, tangible non-transitory computer-readable media, and devices for operating an autonomous vehicle are provided. For example, a method can include receiving sensor data based at least in part on sensor outputs from sensors of an autonomous vehicle. The sensor outputs can be based at least in part on a state of the autonomous vehicle and an environment including one or more objects. A plurality of spatial relations can be determined based on the sensor data. The plurality of spatial relations can include the position of the autonomous vehicle with respect to the one or more objects. A headlight configuration for headlights of the autonomous vehicle can be determined, based on the plurality of spatial relations. The headlight configuration can specify headlight states for each of the headlights. A set of the one or more headlights can be activated, based on the headlight configuration.

A vehicular lighting apparatus is relatively small, low cost, superior in mountability, and offers a superior design. The vehicular lighting apparatus attachable to a front end of a vehicle includes: a composite lens element that is a light guide element constructed by molding a translucent resin substantially into a plate-like shape; a planar light-emitting unit that emits illumination light; an optical system that transforms planar light from the light-emitting unit into linear light and that causes the linear transformed light to be incident on a rear side face of the light guide element; and a diffraction lens formed on the rear side face of the light guide element on which the linear transformed light is incident, and condensing the linear transformed light. The light condensed by the lens means is emitted from a front side face of the light guide element onto a road surface in front of the vehicle.

A lighting device is provided for controlling the photometric distribution of light emitted by two or more LEDs. The lighting device may be integrated with a control system of the vehicle and may be controlled by a remote controller. The lighting device may be capable of being operated in one or more modes of operation based on operating conditions, user input, or both. Operating conditions may include vehicle conditions, environmental conditions, and user conditions. The controller may operate a software application to enable the user to modify, control, or otherwise regulate any mode of operation or other feature of the lighting system.
