LIGHT DISTRIBUTION CONTROL SYSTEM OF LIGHTING FIXTURE FOR VEHICLE |
摘要 |
<p>PROBLEM TO BE SOLVED: To change light distribution for a light distribution control system of a lighting fixture for a vehicle without giving a driver a sense of incongruity even when the vehicle is accelerating and decelerating. SOLUTION: A main control circuit of the light distribution control system of the lighting fixture for the vehicle calculates acceleration of a vehicle at a step 112 while the vehicle is running and controls light distribution by selecting either mode based on the calculated acceleration. When the vehicle is running at a constant speed, light distribution control by a normal mode is practiced at a step 116. When the vehicle is accelerating, light distribution control by an acceleration road mode is practiced at a step 118 and light distribution of a group of lamps is switched at timing which is earlier than that of practice of light distribution control by a normal mode. When the vehicle is decelerating, light distribution control by a deceleration mode is practiced at a step 120 and light distribution of a group of lamps is switched at timing which is later than that of practice of light distribution control by a normal mode.</p> |
