Abstract
An apparatus for controlling light distribution of a vehicle head lamp has a first calculating means for estimating a driver's view position, a second calculating means for estimating a deviation angle formed by a running direction of the vehicle and a direction of the driver's view position, control means for controlling the light distribution composed of beam orientation, beam spread and upper bright-dark limit, said control means further comprising control-lamp selecting means which selects a high-beam head lamp or a low-beam head lamp corresponding to the result of the first calculating means. The first calculating means estimates a driver's view position which is determined by the distance reached by the vehicle after an estimated time along a forward roadway, which accounts for the driver's abilities. The second calculating means provides the deviation angle formed between the running direction of the vehicle and the direction of the driver's line of view.
