Abstract
Systems and methods for controlling an implement based upon a gear shift include a shift detector circuit which detects a direction of the gear shift and an implement controller circuit which adjusts an implement in response to the direction of the gear shift.
Claims21
A system for automatically adjusting an implement, the system comprising:
- a shift detector circuit configured to detect a direction of a gear shift from a gear engaged with an engine to a desired gear, before the desired gear is engaged with the engine, wherein the shift detector circuit outputs an electrical signal representative of the direction of the gear shift;
- and
- an implement controller circuit configured to receive the electrical signal and adjust a position of the implement in response to the electrical signal.
A method for automatically adjusting an implement, the method comprising:
- determining a direction of a gear shift of a transmission based upon a desired gear and a gear of the transmission engaged with an engine before the desired gear is engaged with the engine;
- and
- automatically adjusting the implement in response to the direction of the gear shift.
A system for automatically adjusting an implement, the system comprising:
- a shift detector circuit configured to detect a direction of a gear shift of a transmission based upon a desired gear and a gear of the transmission engaged with an engine before the gear shift occurs, wherein the shift detector circuit outputs a first electrical signal representative of the direction of the gear shift;
- and
- an implement controller circuit configured to receive the first electrical signal and adjust a position of the implement in response to the first electrical signal,
- wherein the implement controller circuit includes a valve controller configured to provide an electrical signal to one or more hydraulic mechanisms coupled to the implement and a proportional-derivative controller configured to control a control gain associated with the electrical signal provided to the one or more hydraulic mechanisms.
