AFS is an abbreviation turn auxiliary lighting system. AFS system has three forms:
1 / turn headlights form, that is, within the headlight lamps can be rotated around 8 ° to 15 ° lighting turn a corner.
2 / the use of independent cornering light system, that is, there is a fixed light bulb according to the corners, turn automatically when lit.
3 / fog lights to turn around when the use of lighting, the time corresponding to the curved inside of the fog lights turn on, lighting turn a corner.
I believe friends of the family car at night turn the importance of lighting has a profound experience, when the night was driving in a large arc of the curve or in the absence of street lighting on the mountain, the curve inside the blind spot of light and vision area of the driver and passengers in the car is there is a significant security concerns, threatening the safety of driving at night.
To solve this problem, AFS-(Adaptive Front Lighting System) initiative steering headlight lighting system on this Ting students. Active steering headlight lighting system (Adaptive Front Lighting System, Adaptive Headlights), mainly in the headlamps group or base-mounted rear steering motor, turning the steering wheel when driving, when the computer will collect speed and steering wheel angle signal, and then send control commands to the steering group headlights horse Ta, make it with the actual vehicle turning left and right cornering dynamics and real-time adjustments, so that light beam focused on driving the route, so that drivers can clearly see the front of the vehicle soon after the bend on the road.
AFS technology and in turn to each depot on the mechanism is not nearly the same to Ford (Fu Special) Focus, for example, the AFS in the speed of 3km below, caused by light in order to avoid trouble on the drive to the lane, only to the right start . In the 3km / h or more, will automatically start up to 14 degrees left and right turn. BMW (BMW) active steering headlights will automatically adjust the speed of light as the length of lighting, below 50km per hour urban pattern, more scattering of light will allow motorists to see both sides of the road ; the highway mode, the light will increase the length of exposure, to help drivers see farther ahead. When the fog lights on while driving (speed higher than 70km), light intensity and increase the lighting will increase the width of the range, to provide better sight. AFS may also combine the future mine Ta system, night vision systems and other advanced electronic equipment, to provide more information for the vehicle or combination of GPS signals to provide bend on the road in front of the change to help more precise control of the computer set up with lighting.
In addition, there is a steering auxiliary lighting system the main headlights is fixed, this shift is the same as auxiliary lighting system at night to illuminate the blind spot area curve designed. Active headlights turn with the biggest difference is the lighting system provides illumination of the main headlights driving at night does not rotate, but in the vicinity of the main headlights and then set up a secondary light, transferred to original factory settings when the angle of the steering wheel angle value This auxiliary lights will be turned in order to provide traditional fixed headlights in the corners on the blind spot area lighting.
No matter what kind of steering auxiliary lighting system, the objective is to increase safety while driving, but these systems only an auxiliary, not a panacea and can not absolutely ensure the safety of the crew, therefore, only to develop good driving habits and Tak Road, exact compliance with traffic rules, pay attention to traffic conditions and do regular maintenance and inspection of vehicles is the only way to truly secure
AFS can also be more advanced night vision system with advanced electronic technology, the greater the expansion of lighting performance for the vehicle to provide a more user-friendly lighting effects.
In the future development, AFS system not only to the current state of the environment analysis and processing, combined with the GPS signal to provide changes in the road ahead, the AFS system with ability to foresee in advance to make the appropriate light distribution pattern is the AFS system development trends, But no matter how technology advances to improve the safety of the vehicle traveling at night is always the AFS system is designed.
A large number of high-end collection of the AFS system, information transmission, processing and control unit to form a more complex structure, the current penetration is not very high, hoping that with AFS technology continues after the improvement and development of more models can be used to more people to enjoy the advanced technology to bring security and convenience.
