Method, apparatus, and computer storage media are disclosed for headlight setting activation via a stalk switch. An example vehicle includes a stalk switch and a headlamp controller. The example headlamp controller is to monitor the stalk switch and detect, in response to identifying the stalk switch is transitioning to a high-beam position, a number of occurrences the stalk switch is set at the high-beam position in a predetermined time period. Also, the example headlamp controller is to activate, in response to determining the number of occurrences is two, a first headlight setting of headlamps.

A method of preparing a vehicle control system having an intended function by using at least two ECUs is provided. One of the at least two ECUs is used for adaptively incorporating a modified portion of the intended function of the vehicle control system through re-design in a short period, while the rest of the ECUs in the vehicle control system sustain and support an unchanging portion of the intended function of the vehicle control system.

A method for adjusting a light-level of at least one headlamp for a vehicle. The method includes a reading in; a determining; an ascertaining; and a providing. In the reading in, a position-signal is read in, which represents the current-position of the vehicle. In the determining, a topography-signal is determined using the position-signal, which represents a stored item of information about a roadway-topography at the current position, especially in the case of a curvature and/or a drop of a roadway. In the ascertaining, an angle of inclination of the headlamp to be adjusted for the optimal illumination of the roadway in front of the vehicle is ascertained using the topography-signal. In the providing, an actuating-signal is provided for an adjustment mechanism of the headlamp using the ascertained-angle of inclination to tilt the headlamp to the ascertained-angle of inclination so that the light level of the headlamp is adjustable.

Various embodiments include methods and vehicles, such as an autonomous vehicle, a semi-autonomous vehicle, etc., for collaboratively directing one or more headlights by two or more vehicles. Various aspects may include receiving, by a first vehicle processor, a first collaborative lighting message from a second vehicle, in which the first collaborative lighting message may request the first vehicle direct one or more headlights of the first vehicle, in collaboration with the second vehicle directing one or more headlights of the second vehicle according to a collaborative lighting plan, and directing, by the first vehicle processor, one or more of the headlights of the first vehicle in accordance with the collaborative lighting plan.

A reflector unit may behave as a retroreflector to reflect light of a selected color. The reflector unit may comprise a first reflector having a first color, a second reflector having a second color, and a mask that either allows incoming light to reach the first reflector and not the second reflector or allows incoming light to reach the second reflector and not the first reflector. An active light unit may emit light of a particular color in response to receiving light. In this fashion, the active light unit may simulate the operation of a reflector. The reflector unit and the active light unit may operate on a bi-directional vehicle.

A headlight controller and a vehicle headlight system including an ADB and AFS can include a headlight controller and an optical unit. The headlight controller can include a system controller and a camera photographing vehicles located in a travelling direction of a subject vehicle, and the system controller can be configured to output a control signal to provide favorable light distribution patterns by using image data output from the camera in accordance with traffic conditions. The optical unit can be configured to emit beam lights using lights emitted from a first and second light-emitting device via a projector lens so that the beam lights can be used as a high/low beam without movable parts. Thus, the disclosed subject matter can include providing vehicle headlight systems that can form various favorable light distribution patterns by utilizing the characteristics of the controller and the optical unit in accordance with the traffic conditions.

A light-emitting diode apparatus includes a support substrate; and a light-emitting diode array formed of multiple light-emitting diodes arranged two-dimensionally on the support substrate, constituting a light distribution center having a highest brightness in the light-emitting diode array, wherein the multiple light-emitting diodes are divided into a plurality of control units, drive currents of which can be individually controlled, wherein the plurality of control units include a plurality of composite control units in each of which a plurality of light-emitting diodes are connected in series, and wherein among the plurality of light-emitting diodes in each of the composite control units, a light-emitting diode which is positioned farther from the light distribution center has a larger light-emitting area than that of a light-emitting diode which is positioned nearer from the light distribution center.

The electronic device described in the present patent application applies to the accessories used to automate the main beams that use sensors to detect the light coming from the vehicles met along roads. The device reduces or even suppresses the undesired effects produced by reflections, onto the surrounding objects, of the lights of the vehicle on which it is mounted, thus avoiding undesired main beam turn-off signals. Said device is particularly convenient to use if mounted after the vehicle is commissioned, being it compatible with wireless transmission systems which make its installation easier.

Each of a pair of (left and right) lamp modules is equipped with a first lamp unit having four first light sources and a second lamp unit having a single second light source, and a horizontally long first light distribution pattern or part of it is formed by selectively lighting one or more of the four first light sources. Furthermore, a second light distribution pattern that is smaller and brighter than the first light distribution pattern is formed by lighting the second light source. The first light distribution pattern and the second light distribution pattern are combined, whereby a high-luminous-intensity region is formed as an overlap of them. The first lamp unit and the second lamp unit are configured so as to be able to swing in a horizontal plane so that the high-luminous-intensity region can be shifted in the left-right direction according to a vehicle running situation.

The present invention relates to an optical element (1), an optical module and a vehicle. The optical element (1) comprises: a light incident section (10) for receiving light directly from a light source; a light exit section (30) having a focal plane (P); and a third section (20) that directs light from the light incident section (10) toward the light exit section (30) in a predetermined manner to generate a predetermined low beam distribution or high beam distribution, where the optical element (1) is implemented integrally.
