Abstract
A utility vehicle, control system, and method are described to allow relief of hydraulic pressure in a hydraulic system of the vehicle once the source of hydraulic pressure (e.g., pump) is de-energized. In some embodiments, a hydraulic control input is provided and operably coupled to the hydraulic system, and an operator control switch is provided and also operably coupled to the hydraulic system. The operator control switch has at least two positions, wherein pressure within the hydraulic system is relieved when the operator control switch is in a relief position and the hydraulic control input is engaged.
Claims20
A control system of a utility vehicle, the control system comprising:
- a hydraulic control input operably coupled to a hydraulic system of the utility vehicle and configured to move one or more components associated with the hydraulic system;
- and
- an operator control switch operably coupled to the hydraulic system and comprising at least two positions, wherein pressure within the hydraulic system is relieved when the operator control switch is in a relief position and the hydraulic control input is engaged.
A utility vehicle comprising:
- a frame;
- an electric motor supported on the frame;
- a hydraulic system operably coupled to the electric motor, wherein the hydraulic system is configured to provide hydraulic power to one or more components of the utility vehicle;
- a hydraulic control input operably coupled to the hydraulic system and configured to move the one or more components;
- and
- an operator control switch operably coupled to the hydraulic system and comprising at least two positions, wherein pressure within the hydraulic system is relieved when the operator control switch is in a relief position and the hydraulic control input is engaged.
A method of controlling a utility vehicle, the method comprising:
- selecting a relief position of an operator control switch, wherein the operator control switch is operably coupled to a hydraulic system of the utility vehicle and comprises at least two positions;
- and
- engaging a hydraulic control input while the relief position of the operator control switch is selected to relieve pressure within the hydraulic system, wherein the hydraulic control input is coupled to the hydraulic system and configured to move one or more components associated with the hydraulic system.
