Headlight system for use in a vehicle that tilts when turning, vehicle that tilts when turning, and a method to control a headlight system

摘要

A headlight system for use in a vehicle that tilts when turning, including the headlight system: a headlight (11) configured to turn on regardless of the vehicle's inclination and illuminate an area in front of the vehicle; a secondary headlamp (13) including a plurality of light sources (13La-13Lc, 13Ra-13Rc) and a lamp body (22, 32) that supports the light sources (13La-13Lc, 13Ra-13Rc), being configured the plurality of light sources (13La-13Lc, 13Ra-13Rc) to start when the vehicle tilts; and a control device (21) that is configured to, when the vehicle is tilted to the right with respect to a vehicle width direction, turn on between the plurality of light sources (13La-13Lc, 13Ra-13Rc) a light source that illuminates an area located in front and to the right of the vehicle with respect to the width direction of the vehicle, and when the vehicle tilts to the left with respect to the width direction of the vehicle, turn on between the plurality of light sources (13La-13Lc, 13Ra-13Rc) a light source that illuminates an area located in front and to the left of the vehicle with respect to the vehicle width direction, characterized in that the control device (21) is supported in the lamp body (22, 32) and includes a single reception port such as a receiver (211p) that receives data in a format for digital data transmission, the data being used to control the switching on of the plurality of sources of light (13La-13Lc, 13Ra-13Rc) of the secondary headlamp (13), where the control device (21) is configured to receive digital data from an external device through the single receiving port, the external device is different from the device control (21) and is mounted on a part of the vehicle other than the headlight system and configured to receive and process outputs from a plurality of sensors, to convert the outputs to the format for digital data transmission, and transmit the resulting to the device control (21).
