System for controlling light quantity of headlight
First Claim
1. A system for controlling a headlight of a vehicle being controlled, the system comprising:
- a detector configured to provide a parameter value of a dazzling level of a driver of an other vehicle ahead of the controlled vehicle based on information associated with a relative positional relationship between the controlled vehicle and the other vehicle, the dazzling level representing a possibility that the driver of the other vehicle feels dazzling from light irradiated from the headlight of the controlled vehicle;
a speed sensor configured to measure a speed of the controlled vehicle;
a processor configured to determine a target light quantity based on the parameter value, the processor further configured to determine a lower limit of the quantity of light to be irradiated from the headlight of the controlled vehicle based on the measured speed of the controlled vehicle, wherein the processor selects the higher of the target quantity and lower limit; and
a light quantity adjuster configured to adjust the quantity of light irradiated from the headlight of the controlled vehicle based on the processor'"'"'s selection.

Abstract
In a system for controlling a headlight of a vehicle to be controlled, a dazzling level determiner determines a parameter value of a dazzling level of a driver of an other vehicle ahead of the controlled vehicle based on information associated with a relative positional relationship between the controlled vehicle and the other vehicle. The dazzling level represents a possibility that the driver of the other vehicle feels dazzling to light irradiated from the headlight of the controlled vehicle. A light-quantity adjuster adjusts a quantity of light to be irradiated from the headlight of the controlled vehicle based on the determined parameter value of the dazzling level.

13. A method of providing control of a headlight of a controlled vehicle, the method comprising:
-
determining a parameter value of a dazzling level of a driver of an other vehicle ahead of the controlled vehicle based on information associated with a relative positional relationship between the controlled vehicle and the other vehicle, the dazzling level representing a possibility that the driver of the other vehicle feels dazzling from light irradiated from the headlight of the controlled vehicle; computing a target quantity of light to be irradiated from the controlled headlight based on the parameter value; measuring a speed of the controlled vehicle; computing a lower limit of light quantity to be irradiated from the controlled headlight based on the measured speed; selecting the higher quantity between the target and the lower limit; and adjusting the quantity of light irradiated from the headlight of the controlled vehicle based on the selected quantity. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
