Abstract:
A control system for vehicular illumination, comprising:a first detector detecting a circumferential illumination intensity of a vehicle;a second detector detecting a travel time of the vehicle;a third detector detecting a travel distance of the vehicle associated with the travel time; anda controller operative in an automatic mode thereof to turn a head lamp of the vehicle on and off depending on the circumferential illumination intensity, the travel time, and the travel distance, whereinthe controller has preset values for the automatic mode including a first time, a first distance, a first illuminance, and a second illuminance lower than the first illuminance,the controller turns the head lamp off when the travel time exceeds the first time if the circumferential illumination intensity is kept equal to or higher than the first illuminance for the travel time exceeding the first time, andthe controller turns the head lamp on when the travel distance exceeds the first distance if the circumferential illumination intensity is kept equal to or higher than the second illuminance for the travel distance exceeding the first distance.
