Intelligent Auto Headlights

The system features two functions: Twilight Detection automatically turns on the headlights when the light in the surroundings begins to decrease; Front Windshield Wiper Connectivity automatically turns on the headlights when the windshield wipers are used during rain. Through these two functions, it becomes easier for other drivers and pedestrians to notice your vehicle during rain or twilight, when accidents are prone to occur.

To the role of headlights used at night the system adds the merit of making your vehicle more visible to others around you when it is raining or twilight. These early lighting functions have been called “Considerate Lighting.” It is characterized by being able to turn on headlights in specific driving scenarios as compared to conventional automatic lighting systems.

Twilight Detection expands the conventional distinguishing range of sensors measuring the brightness of the surroundings, enhancing the precision so as not to misidentify the daytime shadows with dusk. By determining if the vehicle has entered a shady area or whether the surroundings have become darker, the system avoids unnecessary automatic lighting when passing through shade. Additionally, because the automatic lighting function senses when the headlights should be turned on, the headlights may come on at more appropriate times; for example, earlier than when a driver would have manually turned them on. The Front Windshield Wiper Connectivity automatically turns on the car headlights when the windshield wipers are used continuously during rain, causing the vehicle to become more conspicuous.

The Twilight Detection system works in the same way as conventional models, detecting the brightness of the surroundings through an illumination sensor set up on the front of the vehicle. It makes distinctions based on differences in the average illumination values and illumination time between driving inside a tunnel, passing through shade, or under a raised intersection. Further, in order to eliminate the frequent turning on and off of headlights, the system is set to remain lit for longer. The Front Windshield Wiper Connectivity is set to turn on the headlights after the windshield wipers have been activated for a certain number of times. Once turned on, the headlights are deactivated if the windshield wipers are not used for a set period of time.
