A driving device for driving an in-vehicle lighting device in which a plurality of light sources are arranged in one direction, comprising a detection unit configured to detect an environment of a vehicle, and a driving unit configured to drive the plurality of light sources in sequence in the one direction, wherein the driving unit drives the plurality of light sources so that driving timings of the plurality of light sources will change in accordance with a detection value obtained by the detection unit.

An early-warning system, method, and apparatus for steering of a two-wheeled vehicle, and a corresponding two-wheeled vehicle including a display apparatus. The system includes: a first control system and a second control system both operating independently and exchanging data between each other in real time; the first control system is configured to: monitor a steering state of the two-wheeled vehicle in real time and generate steering state data; generate early-warning state data based on the steering state data; transmit at least part of the steering state data and the early-warning state data to the second control system in real time; and control corresponding components of the two-wheeled vehicle to operate according to control instructions received from the second control system and internal preset instructions; and the second control system is configured to: control a display of the display apparatus based on the steering state data and/or the early-warning information.

In a turn signal cancelation system for a two-wheeled vehicle, a controller is adapted to automatically cancel the turn signal of the vehicle upon: (a) a determined distance traveled by the vehicle after an occurrence of the predetermined operation of the vehicle exceeding a first distance threshold and a determined yaw angle traversed by the vehicle after the occurrence of the predetermined operation of the vehicle exceeding a yaw angle threshold; and (b) the determined distance traveled by the vehicle after the occurrence of the predetermined operation of the vehicle exceeding a second distance threshold, different from the first distance threshold, independent of the determined yaw angle traversed by the vehicle after the occurrence of the predetermined operation of the vehicle.

A lamp control device comprises a first input terminal, a second input terminal, an output terminal that is configured to be connectable to a lamp via an external switch and outputs a drive current for the lamp, an internal switch provided on a first path connecting the first input terminal and the output terminal, a constant current section provided on a second path connecting the second input terminal and the output terminal, a voltage monitoring section that monitors a voltage applied to the output terminal, and a control section that controls the internal switch on the basis of a monitoring result from the voltage monitoring section.

The present invention provides a signal gear for cyclist to give brake and turn signals to other road users while the cyclist has full control of the handle bar and brake. The signal gear of the present invention is preferably a glove with finger portions. Control and activation of the turn and/or brake signals is mainly by using electrical conductive nature of the signal glove as a switch of the signaling component which is either incorporated with the glove or with the vehicle (e.g. bicycle). The signaling component can emit turn/brake light signal or transmit an activation signal to a light emitting device to give turn/brake light signal. The turn and brake light signals are in yellow and red color, respectively.

A first lamp unit and a second lamp unit arranged in a given direction are provided, luminous intensity of the second lamp unit in a lamp forward direction is set to be higher than luminous intensity of the first lamp unit in the lamp forward direction, and the first lamp unit and the second lamp unit are turned on sequentially with time difference. Thus, since the first lamp unit and the second lamp unit having different luminous intensity and being arranged in the given direction are turned on sequentially with time difference, it is visually recognized that emitted light flows from one side to the other, and the light is emitted from both the first lamp unit and the second lamp unit that has higher luminous intensity than that of the first lamp unit. Thus, it is possible to ensure high conspicuity in addition to improvement of functionality.
