More Information
Summary:A control system is disclosed for use in a zero turn vehicle, including an electric controller in communication with a pair of independent drive units. A joystick is pivotable between a plurality of pivot positions, each pivot position corresponding to a particular rotational speed and direction of each driven wheel. A plurality of driving modes stored in the controller each map a different set of speeds and directions for each driven wheel onto the plurality of pivot positions. The joystick may also rotate about a vertical axis to provide zero turn capability. In at least one driving mode, when the rotational speed of one driven wheel is zero, the rotational speed of the other driven wheels is zero, and when the rotational speed of one driven wheel is non-zero, the rotational speed of the other driven wheel is non-zero.
