ABSTRACT:
A vehicle lighting system1reads position data of a plurality of nodes which are situated ahead of and behind the current position of a cruising vehicle using vehicle current position data and road map data to estimate the shape of a driving path by connecting the plurality of nodes via an interpolation process. Then, as to nodes which are recognized as change points of the shape of the driving path by a road node characteristic position detecting device4, for example, a bending point or inflecting point, and a starting point and a terminating point of a curve path, a transition range is set ahead of and behind the nodes by a transition range setting device5. Then, when the cruising vehicle runs through the range so set, a control quantity related to the illumination control of a vehicle headlamp10is made to be changed slowly.
