Abstract
A system for a vehicle includes a gear and a plate fixed to the gear. The gear is driving by a motor for providing relative rotation between a steering wheel and steering shaft of the vehicle in an adaptive front steering system. The system includes a solenoid including a coil and a pin moveable relative to the coil to engage the plate based on a signal. A sensor is configured to detect a change in current through the coil associated with initial movement of the pin relative to the coil. The system includes a controller programmed to change the duty cycle signal in response to the change in current to slow movement of the pin to reduce or eliminate a clicking noise associated with the pin seating in an extended position or retracted position.
