Steering system having multiple strategies and variable deadzone
First Claim
1. A steering system for a machine having at least one steerable traction device, comprising:
- an operator input device configured to produce steering signals indicative of a desired machine steering maneuver;
a steering actuator operatively connected to the at least one steerable traction device; and
a controller in communication with the steering actuator and being configured to;
control operation of the steering actuator in response to a position of the operator input device during a first operational condition; and
control operation of the steering actuator in response to a speed of the operator input device during a second operational condition,wherein the position of the operator input device affects a steering command for operation of the steering actuator during the first operational condition, andwherein the speed of the operator input device affects a steering command for operation of the steering actuator during the second operational condition.

Abstract
A steering system for a machine having at least one steerable traction device is disclosed. The steering system may have a steering actuator operatively connected to the at least one steerable traction device, and a travel speed sensor configured to generate a signal indicative of a travel speed of the machine. The steering mechanism may also have an operator input device having a deadzone. The deadzone may vary in response to the signal. The steering system may also have a controller in communication with the steering actuator, the operator input device, and the travel speed sensor. The controller may be configured to affect operation of the steering actuator in response to operation of the operator input device only when the operation of the operator input device deviates from the deadzone.
