The system further includes a vehicle lighting control device configured to operate the vehicle lighting based on the vehicle lighting control signal of the main control device and change a position to which the vehicle lighting emits light based on a user movement.

A refuse vehicle includes a chassis, a vehicle body supported by the chassis, a lift assembly, and a projector. The vehicle body defines a receptacle for storing refuse. The lift assembly is configured to selectively engage a waste container. The lift assembly is movable between a first position and a second position. The projector is positioned to emit light outwardly away from the refuse vehicle and proximate the lift assembly to define a target area.

A vehicular exterior door handle assembly includes a base portion that mounts at a door and a handle portion. The handle portion is movable relative to the base portion between a recessed position and an extended position. A light module is disposed between the base portion and an outer panel of the door at or near a cutout region of the outer panel of the door. With the handle portion in the recessed position, a light emitting element of the light module at least partially circumscribes the handle portion. With the handle portion in the extended position, the handle portion extends at least partially through the cutout region. With the handle portion in the extended position, the light emitting element emits light that passes through the cutout region of the outer panel of the door to illuminate the handle portion.

A method for projecting at least one image or video inside or outside a vehicle, in particular an automobile, includes the following steps: providing data of the image or video in a data memory; reading-out the data of the image or video by means of a microcontroller of the vehicle and forwarding an image signal to a light projector, which displays the image or video as long as a control unit of the vehicle having a higher computing power than the microcontroller is not started up, wherein the microcontroller is suitable for processing the data of the image or video in order to represent them by way of the light projector; and switching over from the microcontroller as data source for the light projector to the control unit as data source for the light projector after a defined time period as soon as the control unit has been started up.

The invention relates to a method for managing image data in an motor vehicle lighting system, the lighting system including at least one lighting module intended to project light beams generated on the basis of data relating to the selection of at least one image. The method including receiving an instruction to activate at least one image to be projected, converting the original image into N grey levels, determining, for each pixel in each row in the matrix, whether the pixel under analysis is a significant point of inflection, storing the pixel under analysis as a compressed pixel in a list when the pixel under analysis is considered to be a significant point of inflection, and transmitting the list to the at least one lighting module so that it is able to project a resulting image.

A mobile terminal for identifying a dispatched vehicle using an automotive lamp includes at least one processor and a storage medium storing a computer-readable instruction. When executed by the at least one processor, the computer-readable instruction causes the at least one processor to transmit a vehicle call request including a user identification code, to receive an optical signal output from the vehicle based on the vehicle call request, and to identify whether the vehicle is the dispatched vehicle based on the received optical signal. The optical signal includes the user identification code output through the automotive lamp.

The invention provides a method for managing image data in a motor vehicle lighting system, the lighting system including at least one lighting module intended to project light beams, the light beams being generated from data relating to the selection of at least one image, each image being respectively defined by a matrix including a plurality of horizontal or vertical rows of pixels, with each pixel having a numerical value related to a light intensity of the pixel. The method includes determining whether the pixel under analysis is considered to be a significant point of inflection of the image, so as to transmit it to at least one lighting module, so that it is able to project a resulting image.

Provided is an angle-adjustable projection device for vehicles, including a bracket assembly and a projection lamp assembly. The bracket assembly includes a fixed bracket fixed to the vehicles and a movable bracket fixed to the fixed bracket. The projection lamp assembly is rotatably connected to a cantilever of the movable bracket. The movable bracket is provided with an adjustment screw, the threaded portion of the adjustment screw is screwed into an adjustment screw hole of a housing of the projection lamp assembly. When the adjustment screw is rotated, the projection lamp assembly can be controlled to rotate relative to the cantilever, thereby adjusting the direction and angle of the image projected by the projection lamp assembly.

Provided is a vehicle light system using existing interior lamps and exterior lamps, the interior lamps and the exterior lamps cooperating to provide dramatic illumination. The vehicle light system can include: a lighting control unit that generates and outputs a control signal for controlling the turning on and off of both the exterior lamps and the interior lamps; a light source driving unit that drives the light source of any lamp of the vehicle lamp group on the basis of the control signal provided from the lighting control unit; an in-vehicle device that is mounted on the vehicle and that has a wireless communication function; a portable device that can be carried outside the vehicle by an occupant of the vehicle and that has a wireless communication function with the in-vehicle device; and an in-vehicle network configured to connect the in-vehicle device and the lighting control unit. The lighting control unit acquires positional information for the portable device through the in-vehicle network, and generates and outputs a control signal whereby both the interior lamps and the exterior lamps cooperate to provide lighting when the occupant enters a predetermined range. The commercial value of a vehicle light can thereby be increased.

A vehicular exterior door handle assembly includes a base portion that mounts at a door and a handle portion. The handle portion is movable relative to the base portion between a recessed position and an extended position. The handle portion includes a slider element and a flexible cover element that is coupled to the slider element and that is graspable by the user. An actuator is electrically operable to move the handle portion between the recessed position and the extended position by imparting rotational movement of a cam shaft relative to the base portion. As the cam shaft rotates relative to the base portion, a cam rotates with the cam shaft and engages the slider element, which moves laterally relative to the base portion according to rotation of the cam to move the handle portion between the recessed position and the extended position.
