Lighting control device and lighting control method for vehicle lamp, and vehicle lamp system

Abstract

The purpose of the present invention is to reduce the feeling of discomfort when performing a sequential turn instruction. A lighting control device for a vehicle lamp is used for controlling lighting of the vehicle lamp, and the lighting control device performs control such that a bright spot obtained by lighting a partial region of a light-emitting region of the vehicle lamp is moved in a prescribed direction in the light-emitting region, and when the bright spot is moved in the prescribed direction in the light-emitting region, the light-emitting region of the vehicle lamp is lighted in the prescribed direction, and the light-emitting region of the vehicle lamp is lighted in the prescribed direction. The bright spot is moved such that a first region, which is a partial region corresponding to the bright spot in the first period, and a second region, which is a partial region corresponding to the bright spot in the following second period, partially overlap.

Description

technical field [0001] The present invention relates to, for example, a vehicle lighting system used as a turn signal (winker). Background technique [0002] As one type of winkers used in vehicles, there is known a winker in which a plurality of light emitting units are sequentially turned on with a time difference (for example, refer to Patent Document 1). Here, such a lighting method is called sequential turn indication. A vehicle lamp that performs such a sequential turn instruction is, for example, controlled to repeat an operation in which each light emitting unit is turned on sequentially from the inside toward the outside of the vehicle, and then all the light emitting units are simultaneously turned off. [0003] In a vehicular lighting device that performs sequential turn instructions as described above, it is conceivable to increase the size of an area (bright spot) that lights up at a certain timing to further improve its visibility. In this case, for example, ...

AI Technical Summary

Problems solved by technology

However, since there is a limit to the width of the place where the turn signal can be installed, the number of bright spots that can be formed from one end of the turn signal to the other cannot be made so large.

Therefore, for example, when the bright spot is moved quickly, the movement of the bright spot ends immediately, which may cause a sense of incongruity as a sequential turn instruction.

On the other hand, for example, in the case of moving the bright spot slowly, the movement of the bright spot does not end immediately, but the movement does not become smooth, so there is still a sense of incongruity as a sequential turning instruction
