METHOD AND APPARATUS FOR VARIABLE REDUCED EFFORT STEERING IN ELECTRIC STEERING SYSTEMS

Document Type and Number:

WIPO Patent Application WO/2012/155089

Kind Code:

A3

Abstract:

Embodiments of the invention provide methods and apparatus for reducing steering effort in a vehicle. In one embodiment, a method for installing a steering-assist system onto a vehicle having an electrically powered steering system is provided. The method includes placing a controller between a torque sensor and an electronic control unit (ECU) disposed on the vehicle, coupling a primary signal line from the torque sensor to be in electrical communication with the controller, and coupling a secondary signal line to the controller to be in electrical communication with the ECU, wherein, when movement is detected by the torque sensor, the torque sensor provides a primary signal to the controller and the controller provides a secondary signal to the ECU, the secondary signal being different than the primary signal.
