A vehicular headlight () includes a first light source unit (), a second light source unit (), a temperature sensor (), and a control unit (). When the temperature derating is performed on the first light source unit () based on the temperature in a state where the light distribution pattern () of a low-beam is formed, the control unit () controls the power to be supplied to each of a plurality of light-emitting elements () so that the light amount of at least a part of the first light with which at least a region () of a first light distribution pattern () is irradiated decreases as compared with that before the temperature derating.

A vehicle headlight () includes a first lamp unit (), a second lamp unit (), a region determination unit (), and a control unit (CO). A first irradiation spot (S) overlaps with a second irradiation spot (S). The control unit (CO) controls the first lamp unit () so that an amount of the light of a light emitting element () corresponding to the first irradiation spot (S) overlapping with a predetermined region () is reduced, and controls the second lamp unit () so that an amount of the light of a light emitting element () corresponding to the second irradiation spot (S) overlapping with the predetermined region () is reduced or becomes 0, and light is emitted from the light emitting element () corresponding to the second irradiation spot (S) overlapping with the first irradiation spot (S) and not overlapping with the predetermined region ().

Vehicle headlight

A vehicle headlight () includes a first lamp unit () that includes a light distribution pattern forming unit () which forms a predetermined light distribution pattern (P) according to the light amount of the light emitted from a plurality of light emitting elements (), and a second lamp unit (), in which a light distribution pattern (PL) of a low beam is formed by light emitted from the first lamp unit () and light emitted from the second lamp unit (), and in the light distribution pattern (PL) of the low beam, the elbow point (EP) is included in a predetermined region (CA) formed by light including the light from the first lamp unit (), and a first side region (SA) and a second side region (SA) sandwiching the predetermined region (CA) are formed by the light emitted from the second lamp unit ().

A driving assistance system includes an illumination apparatus and a controller. The illumination apparatus is configured to draw an avoidance pattern PTN on a road surface such that it indicates a lane in which the driver's vehicle is to travel or a direction in which the driver's vehicle is to travel. Upon detecting, by a sensor or communication, an obstacle in front of the driver's vehicle, the controller instructs the illumination apparatus to draw the avoidance pattern PTN.

Driving assistance system

A vehicular display device includes at least one display panel arranged on a vehicle body of a vehicle and configured to display an image, and a display control unit configured to control display of the image. The display panel includes a movable portion provided on the vehicle body, and the display control unit includes an image control unit configured to control a display form of an image when the movable portion is operated.

Vehicular display device

There is provided an aiming adjustment method for a vehicle headlamp which performs aiming adjustment based on a reference point on a light-dark boundary of a light distribution pattern, the method includes setting, as the reference point, an intersection between a vertical light-dark boundary of a part of multi-divided light distribution patterns which are to be synthesized to form a high-beam light distribution pattern and a horizontal light-dark boundary of a low-beam light distribution pattern.

Problem: To clearly indicate an autonomous driving state and a charge level of a battery of a vehicle with a single lamp. Solution: A vehicle headlamp () includes a communication lamp () for indicating an autonomous driving state of a vehicle while the vehicle is driving, and a lamp ECU () for performing control to cause the communication lamp () to indicate a charge level of a battery () while the vehicle is stationary. The lamp () includes an elongated light guide body that continuously extends along a straight line or a curve and a plurality of light emitting devices () arranged at an interval in a longitudinal direction of the light guide body. The lamp ECU () controls the output of light from each of the light emitting devices () to change an illuminated range of the light guide body according to the charge level of the battery ().

A vehicle illumination system provided to a vehicle capable of traveling in an autonomous driving mode includes: an illumination unit configured to emit light toward an outside of the vehicle; and an illumination controller configured to change an illumination mode of the illumination unit, depending on a waiting time of the vehicle.

Vehicle illumination system and vehicle

A vehicle lighting system is provided in a vehicle capable of traveling in an automated driving mode. The vehicle lighting system includes an automated driving system (ADS) lamp configured to emit light toward an outside of the vehicle to visually present information relating to automated driving of the vehicle, and a lighting control unit configured to determine brightness of the ADS lamp according to at least one of a distance between an object outside the vehicle and the vehicle, an attribute of the object, and a road surface condition around the vehicle.

The configuration is provided with three flexible arms extending in the same circumferential direction, as a suspension for supporting the magnetic circuit unit in displaceable fashion in the vertical direction with respect to a coil support member. This assures sufficient length of each of the flexible arms, enhancing the vibration characteristics. Next, arm insertion slots having approximately the same vertical Width as the flexible arms are formed at three locations in the circumferential direction in the coil support member. The distal end of each flexible arm is then inserted into the arm insertion slot, doing so in the aforementioned same circumferential direction, causing a barb to engage an engaging part and detain the flexible arm.

A vehicle lamp includes a light source, a front cover made of a transparent material to transmit light emitted by the light source, a lamp body forming a lamp housing together with the front cover, and a vibrator configured to vibrate the front cover to generate a vibration sound. The vibrator is supported by the lamp housing such that the vibrator contacts the front cover at a location where, when the vehicle lamp is mounted on a vehicle, the vibrator is not visible from an outside of the vehicle lamp.

A vehicle headlamp apparatus is provided. The vehicle headlamp apparatus includes a first lamp configured to selectively produce a first high beam light distribution pattern and an infrared light distribution pattern, a second lamp configured to selectively produce a second high beam light distribution pattern and a low beam light distribution pattern, a vehicle detector which detects a vehicle running ahead, and a condition-dependent selection controller which controls the first and second lamps. The condition-dependent selection controller controls the second lamp to produce the low beam light distribution pattern when the vehicle detector detects a vehicle and to produce the second high beam light distribution pattern when the vehicle detector detects no vehicle. The condition-dependent selection controller controls the first lamp to produce the infrared light distribution pattern, irrespective of whether the vehicle detector detects a vehicle.

Vehicle headlamp apparatus and control method thereof

An automotive headlamp apparatus includes a left lamp unit, a right lamp unit and a headlamp apparatus control unit. Each of the left lamp unit and the right lamp unit includes a bulb, a movable shade, a shade moving mechanism and a fixed shade. Each movable shade can advance or recede with respect to the light axis of the bulb, and forms an individual light distribution pattern for a low-beam by shielding part of a light at an advanced position while allowing formation of a partial shape of a light distribution pattern for a high-beam at a receded position. The fixed shade forms the partial shape of the light distribution pattern for a high-beam when the movable shade is located at the receded position. A pattern control unit determines each shape of the individual light distribution patterns by controlling each of the shade moving mechanisms in the left lamp unit and the right lamp unit, and also determines a shape of a synthesized light distribution pattern by superimposing each of the individual light distribution patterns one on another.
