PURPOSE:To control each brightness of car lights in accordance with the surrounding brightness outside a car respectively and correctly by controlling brightness of head lamp, indication lamp, brake lamp, and room lamps according to the time- sharing computation process with a microcomputer. CONSTITUTION:The generation of the first illumination condition is decided by the detection of the surrounding light outside a car, and at this decision, the brightness of the first light is controlled in accordance with the detected surrounding brightness. Then, the generation of the second brightness different from the first one is decided, and by this decision, the brightness of the second light is controlled in accordance with the detected surrounding brightness. A course of above-said processes is repeated by time-sharing. A microcomputer 8 receives digital signals from a light sensor 1 and a car speed sensor 2 via an A/D converter 7 and switch signals from an ignition switch 3, a brake switch 4, a room lamp switch 5, and a door switch 6 for making processing of time sharing. |
