Apparatus for controlling light distributions of head lamps

An apparatus for controlling light distribution of a head lamp of a vehicle in which performance is changeable, comprising:

• a sensor for detecting a vehicle operating condition;
• a first calculating means for estimating a view position of a driver of said vehicle which is determined by a distance reached by said vehicle after an estimated time along a forward roadway, said estimated time being determined in accordance with a driver's abilities which is determined by the level of driving skillfulness;
• a second calculating means for estimating at least one of a deviation angle formed by a running direction of said vehicle and a direction of said driver's view position, and an upper bright-dark limit of the head lamp;
• a control means for controlling the light distribution composed of beam orientation/spread and upper bright-dark limit of said head lamp on a basis of a result of a calculation by said first and second calculating means,
• said control means including a control-lamp selecting means for automatically selecting a high-beam head lamp or a low-beam head lamp automatically based on a result of the first calculating means.

An apparatus for controlling light distribution of a head lamp of a vehicle in which performance is changeable, comprising:

• a sensor for detecting a vehicle operating condition;
• a first calculating means for estimating a view position of a driver of said vehicle which is determined by a distance reached by said vehicle after a predetermined time along a forward roadway;
• a second calculating means for estimating a deviation angle formed by a running direction of said vehicle and a direction of said driver's view position, and said deviation angle being modified within the driver's field of vision based on a configuration of the forward roadway;
• a control means for controlling the light distribution composed of beam orientation/spread and upper bright-dark limit of said head lamp on a basis of a result of a calculation by said first and second calculating means,
• said control means including a control-lamp selecting means for automatically selecting a high-beam head lamp or a low-beam head lamp based on a result of the first calculating means.
