Lincoln Aviator: Power Steering / Description and Operation - Adaptive Steering - Overview
Overview
The
adaptive steering system changes the steering ratio between the
steering wheel and the road wheels dynamically, thereby reducing the
number of steering wheel turns required to turn the road wheels. This is
accomplished through the use of a motor, worm gear and toothed hub. All
adaptive steering system components are inside the steering wheel,
behind the driver airbag.
