Abstract
The present invention is directed to a computer based control system for controlling hydraulic and electromechanical actuators on a power machine, such as a skid steer loader. The computer based control system is configured to implement a number of features to enhance certain operational aspects of the power machine. One such feature includes an operator actuable selector which provides a selector signal based on an operator input. A controller receives the selector signal and provides an auxiliary output signal to control an auxiliary valve in a selected one of an on/off mode and a proportional mode based on the selector signal.

A power machine control system, comprising:
- a hydraulic system including, a primary hydraulic coupler connected, through a primary valve, to a source of hydraulic fluid and an auxiliary hydraulic coupler connected, through an auxiliary valve, to the source;
- an operator actuable selector providing a selector signal based on an operator input;
- and
- an electronic controller, coupled to the auxiliary valve and the selector, configured to receive the selector signal and provide an auxiliary output signal to control a valve spool in the auxiliary valve in a selected one of an on/off mode and a proportional mode based on the selector signal.
A power machine, comprising:
- a hydraulic system including, a source of hydraulic fluid, a primary valve, a primary hydraulic coupler connected, through the primary valve, to the source of hydraulic fluid, an auxiliary valve, and an auxiliary hydraulic coupler connected, through the auxiliary valve, to the source;
- a primary hydraulic actuator coupled to the primary hydraulic coupler;
- an auxiliary hydraulic actuator coupled to the auxiliary hydraulic coupler;
- an operator actuable selector, disposed on a hand grip of a steering lever, providing a selector signal based on an operator input;
- and
- an electronic controller, coupled to the auxiliary valve and the selector, configured to receive the selector signal and provide an auxiliary output signal to control a valve spool in the auxiliary valve in a selected one of an on/off mode and a proportional mode based on the selector signal.
