PROBLEM TO BE SOLVED: To achieve both sufficient anti-glare and an improvement of visibility to a driver by contriving left and right margins of a shading range to follow-up delay and setting of follow-up limit quantity in a head lamp light distribution control device for a vehicle for finishing follow-up when changing a shading range while following the position of a vehicle in front to find that the vehicle in front is separated from the front of one's own vehicle only by the follow-up limit quantity.SOLUTION: Whether a vehicle in front is a preceding vehicle or an oncoming vehicle is determined (step 105), when the vehicle in front is the preceding vehicle, an optical axis control margin corresponding to left and right margins of a shading range to follow-up delay is set smaller than when the vehicle in front is an oncoming vehicle to set the maximum shading range to a follow-up limit quantity (steps 115, 120, 125, 130). |
