System, methods, and other embodiments described herein relate to improving the sensing and lighting coverage of a first vehicle using a second vehicle. In one embodiment, a method includes determining at least one of a sensor coverage and a lighting coverage of a first vehicle and a second vehicle. The method further includes controlling the second vehicle to park in a position that maximizes the at least one of the sensor coverage and the lighting coverage between the first vehicle and the second vehicle while the first vehicle is stationary. Moreover, the method includes activating at least one of sensors and lighting mechanisms of the first vehicle and the second vehicle.

Systems and methods are provided herein for dynamically attenuating light transmissibility. For example, the disclosed system detects a light source emanating light that intersects a viewing aperture. The viewing aperture includes a polarizing layer. The system determines a light intensity and a location of the light source corresponding to the detected light. The system determines, based on the determined light source location, a location at which the light intersects the viewing aperture. The system activates the polarizing layer based on the determined light source location. In some embodiments, the polarization layer includes a nanostructure having a plurality of horizontal rods and a plurality of vertical rods arranged in a grid pattern. The nanostructure includes a plurality of pixels, each pixel of the plurality of pixels defined by the intersection of a horizontal rod of the plurality of horizontal rods and a vertical rod of the plurality of vertical rods.

Light from a headlight is prevented from being diffusely reflected on a road surface and reaching an oncoming vehicle. Provided is a lamp control method of controlling a lamp including a lamp unit that projects light over a predetermined range and a driver that turns on and turns off or dims a light projection range of the lamp unit in predetermined units. The lamp control method includes a step of obtaining a reflection region on a road surface where the light projected from the lamp unit is regularly and diffusely reflected by the road surface and reaches a driver of an oncoming vehicle or a preceding vehicle, and a step of controlling the driver so that the light projected onto the reflection region from the lamp unit is turned off or dimmed.

A lamp control system includes a pair of lamps configured to emit light forward; a sensing module configured to sense an adjacent lane of a travelling vehicle; and a processor configured to: receive information on the sensed adjacent lane; and when the adjacent lane corresponds to a specific lane, control a light output of a lamp adjacent to the specific lane among the pair of lamps based on the received information on the adjacent lane. The specific lane may include at least one of a center line and an outermost lane.

A system for controlling a lamp, a method therefor, and a vehicle therefor are provided. The system includes: a pair of lamps to irradiate beams forward based on respective beam patterns thereof; a sensing module to sense an object in front of a subject vehicle in motion; and a processor to receive information on the sensed object, and control the beam pattern of at least one of the pair of lamps such that a shadow area is formed in an area including the object based on the input object information. The shadow area includes a main shadow area corresponding to a width of the object, and a shadow margin area having a predetermined width from each of both sides of the main shadow area. The processor controls the width of the shadow margin area based on at least one of internal factors, external factors, or any combination thereof.

Provided is a drive assist apparatus visually notifying a driver of information regarding a gradient of a road. A drive assist apparatus includes processing circuitry. The processing circuitry is to acquire gradient information of a road in which gradient illusion is estimated to occur in a driver of a vehicle. The processing circuitry is to perform control on an irradiation apparatus provided to the vehicle so that the irradiation apparatus projects a gradient recognition pattern on a target object or on a projection surface provided in front of a driver seat of the vehicle to display the gradient recognition pattern in overlapped fashion with the target object. The target object is located in front of the vehicle and extends along the road. The gradient recognition pattern includes at least one graphic based on the gradient information of the road and disposed along the extension direction of the target object.
