Actuator for active front wheel steering system

摘要

A steering actuator for adjusting an angle of a steerable wheel of a motor vehicle includes an electronic controller, a rack translatable in opposing directions, and a sleeve assembly translatable along a length of the rack and disposed in mechanical communication with the steerable wheel of the vehicle. The rack is drivable in response to an operator input and further drivable in response to an input signal from the electronic controller. A method of using the actuator includes receiving an input from the operator of the vehicle, receiving an input signal indicative of the behavior of the vehicle from a sensing device, calculating an output signal from the operator input and the motor vehicle behavior input signal, and adjusting an angle of the steerable wheel based on the output signal.
