System for detecting locking pin engagement of an implement

A monitoring system for a work vehicle, the work vehicle having a lift system to which an implement is attachable via a connection assembly, the lift system including a movable arm affixed to a frame of the work vehicle and at least one hydraulic cylinder operable to move a portion of the movable arm relative to the frame, the connection assembly including a coupler secured to the movable arm and movable relative thereto to couple the implement at first and second attachment points, the coupler including a pin member receivable within a portion of the implement to form the second attachment point, the monitoring system comprising:

• a weight detection subsystem operable with the lift system, the weight detection subsystem configured to transfer signals representative of a weight supported by the lift system;
• a position detection subsystem operable with the connection assembly, the position detection subsystem configured to transfer signals representative of a state of the connection assembly;
• and
• a controller in operable communication with the weight detection subsystem and the position detection subsystem, the controller configured to
• receive signals from the weight detection subsystem and from the position detection subsystem,
• determine a condition of the connection assembly based on the signals received to determine if the pin member is in an extended state or if the pin member is in a retracted state, and
• output a signal based at least in part on the determined condition.

A non-transitory computer readable medium comprising program instructions for permitting a controller to monitor a work vehicle through stages of attachment of a work implement thereto, the work vehicle including a lift system to which an implement is attachable via a connection assembly, the program instructions when executed causing a processor of the controller to:

• receive signals from a weight detection subsystem operable with the lift system, the signals representative of a weight supported by the lift system;
• receive signals from a position detection subsystem operable with the connection assembly, the signals representative of a state of the connection assembly;
• determine a condition of the connection assembly based on the signals received to determine if a pin member of the connection assembly is in an extended state or in a retracted state;
• determine whether the lift system has changed from a state in which no work implement is supported thereby to a state in which all or a portion of a work implement is supported thereby;
• determine whether the lift system has changed from a state in which all or a portion of a work implement is supported thereby to a state in which no work implement is supported thereby;
• and
• output a signal based at least in part on two or more of the determinations.
