Abstract

A remote angular position display system and method are disclosed. The angular position of a work implement of a work vehicle is displayed (e.g., textually, numerically or graphically) on a display associated with a portable device. The angular position is observed by a sensor coupled to the work implement or the work vehicle. The method includes receiving, by a processor of the portable device, one or more signals from the sensor indicative of an angular position value, and determining, by the processor, a condition associated with the work implement based on the angular position. The method includes outputting, by the processor, an interface for rendering on the display associated with the portable device that indicates the angular position and the determined condition associated with the work implement of the work vehicle.

determining, by the processor, a condition associated with the work implement based on the angular position value, including:
retrieving, by the processor, at least one predefined value associated with the work implement from a datastore;
receiving, from an input device associated with the portable device, at least one user input associated with at least one calibration prompt that indicates that the at least one calibration prompt has been completed by the user to move the work implement to at least one position;
based on the at least one user input, associating the angular position value with the at least one position and storing the angular position value as the at least one predefined value in the datastore; and
comparing, by the processor, the angular position value and the at least one predefined value; and

outputting, by the processor, an interface for rendering on the display associated with the portable device that indicates the angular position value and the determined condition associated with the work implement of the work vehicle.

communicating the angular position value from the gyroscope to the processor of the portable device.

3. The method of claim 1 , wherein the sensor is an inertial measurement unit that observes the angular position of a carrier of the work implement and the method further comprises:
communicating the angular position value from the inertial measurement unit to the processor of the portable device.
