Outline<\/p>\n

\u2022 The adaptive front lighting system (AFS) is a system which enhances the range of visibility when the headlights are turned on by pointing the optical axis of the headlights in the direction in which the vehicle is advancing according to the steering operation.<\/div>\n

Swivel function<\/p>\n

\n
\n
\u2022 The adaptive front lighting system (AFS) control module changes the optical axis to the direction in which the vehicle is travelling according to the steering wheel operation and vehicle speed while the headlights are turned on.<\/div>\n
\u2022 The adaptive front lighting system (AFS) control module controls the swivel function based on the following CAN signals.<\/div>\n<\/dd>\n<\/dl>\n

Initial position learning function<\/p>\n

\n
\n
\u2022 When the ignition is switched ON (engine on) at a vehicle speed of 0 km\/h {0 mph}<\/span>, the adaptive front lighting system (AFS) control module calculates the initial position of the swivel actuator for left\/right operation, and the headlight optical axis stops at the front position.<\/div>\n

Structure\/Construction<\/p>\n

\u2022 The swivel actuator for adjusting the optical axis is built into the front combination light, and it is an integrated construction with the headlights.<\/div>\n
\u2022 The swivel actuator has an internal Hall sensor and sends the current position of the headlight to the adaptive front lighting system (AFS) control module.<\/div>\n
\u2022 The variation (swivel angle) of the optical axis of the headlights is 15 degrees<\/span> for the right and left.<\/div>\n
\u2022 Changes in the headlight optical axis (swivel angle) are controlled freely (non-step) based on the vehicle speed and the steering angle, and the swivel angle differs for each of the conditions.<\/div>\n
\u2022 The steering wheel angle amount changes according to the vehicle speed until reaching the maximum value of the swivel angle ( 15 degrees<\/span>).<\/div>\n\n\n\n

Operation<\/p>\n


<\/p>\n

<\/a><\/p>\n

Swivel function<\/p>\n

\n
\n
\u2022 When the ignition is switched ON (engine off or on), the adaptive front lighting system (AFS) control module constantly calculates the swivel actuator control amount based on the steering angle signal and vehicle speed signal.<\/div>\n
\u2022 If the following operation conditions are met, the adaptive front lighting system (AFS) control module controls the swivel actuator based on the calculated amount of control, and adjusts the headlight optical axis.<\/div>\n<\/dd>\n<\/dl>\n
