<p>PURPOSE:To aim at safety operation by obtaining instantaneous luminous energy and differential luminous energy by means of a luminous energy outputting means depending upon the output of a photo-sensor and performing a fuzzy inferne with respect to the lighting level based on a fuzzy rule, thereby controlling the lighting or lighting-out. CONSTITUTION:Depending upon the output from a photo-sensor 4 mounted on a vehicle 2, a luminous energy outputting means outputs a instantaneous luminous energy data X1 corresponding to instantaneous brightness in the surrounding, and differential luminous energy data X2 corresponding to average brightness with a specified period, which is little changed to the change in instantaneous brightness such as street lighting. The control means 12 of a light controller main body 6 performs a fuzzy inferne with respect to the lighting level of a vehicle 2. Then, when the lighting level exceeds a reference value, the lighting control is performed and when it does not exceed the reference value, the lighting-out control is performed. Thus, it is possible to ensure the safety operation of the vehicle.</p> |
