Abstract
A method for operating a vehicle having variable-speed left-side and right-side propulsion units (such as, without limitation, a tracked vehicle having a left track powered by a left-track motor and a right track powered by a right-track motor). The left-side propulsion unit is controlled by a first output signal from a first manual controller (such as, without limitation, a left joystick). The right-side propulsion unit is controlled by a second output signal from a second manual controller (such as, without limitation, a right joystick). At least one of the first and second output signals is modified to create a substantially identical output signal for the first and second manual controllers when the first and second output signals are within a predetermined tolerance. The left-side and right-side propulsion units are controlled with the identical output signal when the first and second output signals are within the predetermined tolerance.
