<p><P>PROBLEM TO BE SOLVED: To eliminate generation of luminous intensity distribution split phenomenon wherein an irradiation range thereof almost disappears on the front road surface in preceding swivel control by front road information relative to one of left and right head lights (head lamps) and swivel control by steering of a driver relative to the other. <P>SOLUTION: During swivel preceding control of one of the left and right head lights based on a presumption swivel control angle ESWC by a vehicle speed SPD and the front road information DNAVI, when it is determined that the steering of a steering wheel by the driver exists (S107) and the swivel direction is a reverse direction (S109), the swivel control angle SWC is made preferential and the presumption swivel control angle ESWC is guard-processed by a predetermined amountα(S111). Therefore, no delay of swivel control of the left and right head lights relative to the traveling condition of the vehicle and the front road condition is generated and the luminous intensity distribution split phenomenon is not generated even if the front road is a strong (swinging radius of curvature is small) S shape road. Front visibility of the driver can be ensured. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
