Embodiment Construction

[0018] Embodiments of the present invention will be described with reference to the drawings. Figure 1A It is a conceptual configuration diagram of a headlamp to which an embodiment of the present invention is applied. The headlamps include right headlamps R-HL and left headlamps L-HL respectively disposed on the right and left sides of the front portion of the vehicle ("vehicle" in the figure). The right headlight R-HL and the left headlight L-HL have almost the same configuration. Such as Figure 1B As shown in the enlarged view in , the left headlamp L-HL has a projector lamp unit 2 provided in a lamp housing 1 schematically indicated by a dotted line. Inside the lamp housing 1 , a leveling actuator 3 , a rotating actuator 4 and a shade actuator 5 are incorporated to control light distribution of the lamp unit 2 . The leveling actuator 3 tilts the light axis of the light unit 2 in the vertical up-down direction, and the rotary actuator 4 tilts the light axis in the horiz...

Abstract

The invention discloses a light distribution control system for a vehicular headlamp. The light distribution control system includes a headlamp (L-HL, R-HL) configured such that light distribution of the headlamp (L-HL, R-HL) can be controlled based on a plurality of modes of light distribution control, and a light distribution control electronic control unit (10, 10A, 10B) configured to control the light distribution of the headlamp (L-HL, R-HL) based on at least one of the plurality of modes of light distribution control. The light distribution control electronic control unit (10, 10A, 10B) is configured such that a common unit (c) commonly used in the plurality of modes of the light distribution control and a dedicated unit exclusively used in at least one of the plurality of modes of the light distribution control can be mounted.

Description

technical field [0001] The present invention relates to a light distribution control system configured to control the light distribution of vehicle headlamps. Background technique [0002] Up to now, light distribution control devices for controlling light distribution of headlamps have been proposed to enhance visibility in a front lighting area illuminated by headlights of a host vehicle and to prevent Vehicles ahead and users in oncoming vehicles in the illuminated area are dazzled. For example, as a light distribution control device, a leveling control device, a rotation control device, and a light distribution pattern control device have been proposed. The leveling control device deflects the light axis of the headlamp in the up and down direction as the forward and rearward tilt angles of the vehicle body change, and controls the direction of the light axis to be constant with respect to the road surface. The rotation control device deflects the light axis of the hea...
