Patent ID: 8897966

Claim:
A method for installing a steering-assist system onto a vehicle having an electrically powered steering system, the method comprising: 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, wherein the secondary signal comprises a first signal that is amplified to a second signal having a value greater than the primary signal, and wherein the second signal is limited by a limiting circuit to a third signal having a value less than the value of the second signal but greater than the value of the primary signal.
