SWIVEL ACTUATOR

id151100001300


Purpose

•  The swivel actuator drives the motor based on the signal from the AFS control module when the headlights are illuminated to change the direction of the optical axis of the headlights according to the steering wheel operation.

Function

•  The swivel actuator constantly detects the headlight swivel angle from the hall sensor built into the actuator, and inputs the swivel angle to the AFS control module via LIN communication.

Construction

•  The swivel actuator is built into the front combination lights.
•  The swivel actuator has an integrated hall sensor.

Operation

1.  The AFS control module sends the target headlight optical axis signal to the swivel actuator based on the headlight current position signal from the swivel actuator.

2.  The swivel actuator calculates the amount of motor drive based on the target headlight optical axis signal from the AFS control module and drives the motor until the headlights reach the target headlight optical axis position.

3.  The motor is driven and changes the optical axis by moving the reflector left and right.

4.  The swivel actuator detects the current position of the headlights based on the hall sensor, and sends the current position of the headlights to the AFS control module.
