Apparatus and method for controlling light distribution using steering information

An apparatus for controlling light distribution using steering information, the apparatus comprising:

• a camera configured to acquire position information of a front vehicle and calculate an amount of change of a position of the front vehicle from the position information of the front vehicle;
• a steering information detector configured to detect an amount of change of steering information sensed through a steering sensor configured to sense the steering information;
• a determiner configured to determine whether the amount of change of the position of the front vehicle exceeds a predetermined critical value, whether the amount of change of the steering information is greater than or equal to a predetermined critical value, and a direction in which the steering information is changed;
• and
• a controller configured to increase or decrease a margin of a shadow zone of a headlamp according to the amount of change of the steering information when the amount of change of the position of the front vehicle exceeds the predetermined critical value and the amount of change of the steering information is greater than or equal to the predetermined critical value.

A method of controlling light distribution using steering information, the method comprising:

• a detecting an amount of change of steering wheel angle (SWA) information of steering information sensed through a steering sensor that senses the steering information;
• determining whether the detected amount of change of the steering information is greater than or equal to a predetermined critical value and determining a direction in which the steering information is changed;
• and
• increasing or decreasing a margin of a shadow zone of a headlamp according to the amount of change of the steering information when the amount of change of the steering information is determined to be greater than or equal to the predetermined critical value in the determining.
