Patent ID: 7631714

Claim:
A motor vehicle steering control comprising: (a) a joystick control pivotably mounted for controllable clockwise and anti-clockwise pivotal movement from a joystick neutral position and, in response thereto, for producing a first output drive signal corresponding to the degree of such pivotal movement; (b) a yoke control pivotably mounted to said joystick control for controllable clockwise and anti-clockwise rotational movement from a yoke neutral position and, in response thereto, for producing a second output drive signal corresponding to the degree of such rotational movement; (c) a first differential operably coupled to said joystick control and to said yoke control for receiving said first and second output drive signals as input signals and, in response thereto, for combining said first and second input signals to produce a first steering drive signal corresponding to the sum of said first and second input signals; (d) a drive signal inverter operably coupled to said joystick control for receiving said first output drive signal and, in response thereto, for producing an inverted drive signal corresponding to a degree of pivotal movement opposite to an actual degree of degree of pivotal movement of said joystick control from its neutral position; and, (e) a second differential operably coupled to said drive signal inverter and to said yoke control for receiving said inverted drive signal and said second output drive signal and, in response thereto, for combining said inverted drive signal and said second output drive signal to produce a second steering drive signal corresponding to the sum of said inverted drive signal and said second output drive signal.
