Embodiment Construction

[0017] The following is attached Figure 1 Embodiments according to the present invention will be described first.

[0018] A vehicle light control system 1 to which the present invention is applied is mounted on a vehicle VE. The vehicle light control system 1 includes headlights that emit light in the traveling direction of the vehicle VE, and controls the light irradiation direction of the headlights. In particular, the lamp control system 1 of the present embodiment has a function of controlling the light intensity of the headlights according to the radius of curvature of the road on which the vehicle on which the system 1 is installed travels.

[0019] In more detail, as figure 1 As shown, the lamp control system 1 includes a calculation unit 10 , a steering angle sensor 21 , a yaw rate sensor 22 , a vehicle speed sensor 23 , a lamp control unit 31 , and a head lamp 32 . The computing unit 10 functions as a vehicle light control device.

[0020] The steering angle sen...

Abstract

The invention provides a vehicle lamp control system. In this system, the calculation unit sets the maximum light intensity of the vehicle lamp according to the radius of curvature of the road on which the vehicle is traveling ( S140 ). Next, the calculation unit controls the light intensity of the vehicle lamp so that the light intensity of the vehicle lamp is equal to or less than the maximum light intensity (S150, S160). According to this system, the maximum amount of light of the headlights is set according to the radius of curvature. Therefore, an appropriate amount of light is set so as not to dazzle other vehicles.

Description

technical field [0001] The present invention relates to a system, an apparatus and a method for controlling a vehicle light mounted on a vehicle and irradiating light in a traveling direction of the vehicle. Background technique [0002] As such a vehicle light control device, for example, a configuration described in Patent Document 1 is known. The lamp control device described in this patent document 1 is configured to include an auxiliary lamp that emits light in a turning direction when turning, and to turn on or turn off the auxiliary lamp in accordance with a steering angle. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2007-45252 [0004] However, in the above-mentioned vehicle light control device, since the light quantity of the auxiliary vehicle light is constant, other vehicles such as oncoming vehicles may feel dazzling. Want to avoid such a situation. Contents of the invention [0005] Therefore, it is desired to be able to more rel...
