摘要:
A vehicle including an active front steer system including a locking mechanism having a solenoid actuated locking pin and a spring for biasing the pin toward an extended or locked position for engaging a locking disc of the active front steer system wherein the active front steer system further includes a current sensor for sensing the motion of the pin of the solenoid when the engine of the vehicle is shut down and pulse width modulated current to the solenoid is reduced and when the pin movement is sensed, the pulse width modulated current is increased (fed forward duty cycle) to reduce the movement of the pin to reduce the noise made when the metal pin makes when contacting the metal locking disc. The end of the pin and/or the locking disc may also include an insulating material to further reduce any remaining noise made when the metal pin makes when contacting the metal locking disc.
