An apparatus for displaying at least one virtual lane line based on an environmental condition and a method of controlling the same. The method includes recognizing an actual lane line of a vehicle traveling direction through at least one sensor, determining whether a head-up display (HUD) has been installed in a vehicle, upon determining that the HUD has been installed in the vehicle, displaying a first virtual lane line corresponding to the recognized actual lane line through the HUD and displaying a second virtual lane line corresponding to the recognized actual lane line on a road surface through a headlamp, and upon determining that the HUD has not been installed in the vehicle, displaying only a third virtual lane line corresponding to the recognized actual lane line through the headlamp.

A lamp for a vehicle includes a light source unit for generating light, a shield unit for selectively transmitting at least some of the light generated from the light source unit, and a lens unit for focusing the light that transmits trough the shield unit on a road surface. A main transmission light among the light that is transmitted through the shield unit forms a plurality of road surface patterns, and an auxiliary transmission light among the light that is transmitted through the shield unit is irradiated to one or more selected road surface pattern among the plurality of road surface patterns to increase brightness of the selected road surface pattern.

An illumination device for a motor vehicle includes at least one light source and an elongated waveguide which is delimited along the length thereof by a lateral surface. The waveguide is configured to guide light from the at least one light source along a light propagation direction in a totally reflective manner, the light propagation direction corresponding to the length of the waveguide. The light of the at least one light source can be coupled into the waveguide via a coupling surface at an end face of the waveguide, and a decoupling structure is provided in the lateral surface of the waveguide for decoupling light, which exits the waveguide via an exit region of the lateral surface along the light propagation direction, thereby overriding the total reflection condition.

A projection mechanism of a vehicle projection device projects a graphic of a graphic film toward an outer side of a vehicle. A projection direction of the graphic from the projection mechanism is inclined with respect to a rotation axis of the projection mechanism. Thus, by manually rotating a dial to rotate the projection mechanism about the rotation axis, the projection direction of the graphic from the projection mechanism can be altered, and the projection position of the graphic from the projection mechanism can be altered.

A vehicle projection device projects a graphic of a film body housed in a housing toward an outer side of the housing. It is possible to detach the film body toward an exterior of the housing via a communication hole in the housing by gripping a grip portion of the film body. This thereby enables the film body to be detached toward the exterior of the housing.

The disclosure relates to a control device for a motor vehicle, having a sensor unit that is configured to contactlessly detect an object in a sensor zone situated on an outer side of the motor vehicle, and a control unit that is configured to generate a first control signal for at least one actuator according to the detected object, which a movement of an access element can be influenced. In order to improve the reliability and user-friendliness of a control device of a motor vehicle comprising a contactless sensor system, it is provided that the control device comprises a projector unit that is configured to project a light pattern that marks off at least one portion of the sensor zone.

A vehicle headlight system can include a headlight controller and a lamp unit incorporating a high beam module, which can emit favorable marking lights while the headlight controller associates each of a shading driver and a swivel structure with a shading width setter and a swivel setter, respectively. When a forward vehicle does not exist in a forward direction, the headlight systems can provide favorable light distribution patterns by overlapping the light distribution pattern projected from the high beam module with each of light distribution patterns for a high and low beam. When the forward vehicle exists, the headlight system can prevent the lamp unit from emitting a glare type light to the forward vehicle. Thus, the disclosed subject matter can provide vehicle headlight systems, which can emit favorable light patterns toward a pedestrian as a marking light, and which can provide favorable light distribution patterns to drive at night.

A vehicle projection device including: a reflector that is provided in a vehicle and is provided with a reflective surface, with the reflective surface reflecting light; an image member that is provided with an image and through which the light reflected by the reflective surface is transmitted; and a lens through which the light that has been transmitted through the image member is transmitted, whereby the image is magnified and projected.

Disclosed herein is a portable emergency sign device for a vehicle. The portable emergency sign device includes a box-shaped case body, a main laser oscillator, and a reflector. The box-shaped case body provides an installation space therein. The main laser oscillator is installed within the case body, and radiates laser light adapted to display the location region of a vehicle in trouble. The reflector is installed to be selectively projected out of and accommodated within the case body, and reflects the laser light, radiated by the main laser oscillator, onto a road surface.

A diagnostic system of a vehicle is provided herein. The system includes a control unit onboard the vehicle for controlling at least one of a vehicle system and a vehicle subsystem. A device prompts the control unit to diagnose an operating condition of the vehicle and report diagnostic data to the device. A light source onboard the vehicle is operable to project a diagnostic image onto a viewing surface located external to the vehicle.
