Vehicle lamp

A vehicle lamp comprising:

• mask-object detecting means that detects a mask-object to be masked ahead of a self-vehicle;
• prediction means that predicts a position of the mask-object detected by the mask-object detecting means;
• a lamp unit that forms, a light distribution pattern including a non-illumination region that does not illuminate the mask-object positioned at the position predicted by the prediction means,
• non-illumination region setting means that sets, on a basis of the position predicted by the prediction means, the non-illumination region;
• lamp unit controlling means that controls the lamp unit;
• angle detecting means that detects an angle of the mask-object detected by the mask-object detecting means with respect to the self-vehicle;
• difference calculating means that calculates a difference between angles detected by the angle detecting means;
• average moving amount calculating means that calculates, on a basis of the difference calculated by the difference calculating means, an average moving amount of the mask-object detected by the mask-object detecting means;
• and
• correction value calculating means that calculates a correction value by multiplying the average moving amount of the mask-object calculated by the average moving amount calculating means, by a coefficient, wherein
• the position of the mask-object predicted by the prediction means is a position of the mask-object after a lapse of a predetermined time,
• the lamp unit controlling means controls the lamp unit to form, the light distribution pattern including the non-illumination region set by the non-illumination region setting means,
• the prediction means predicts, on a basis of the angle detected by the angle detecting means the position of the mask-object detected by the mask-object detecting means and the prediction means adds the angle detected by the angle detecting means and the correction value calculated by the correction value calculating means to predict the position of the object detected by the mask-object detecting means.
