Abstract
A system is provided for controlling a work machine, including an electric continuously variable transmission. The system includes a microprocessor, wherein the microprocessor is configured to include a state machine for controlling the behavior of a work machine. The state machine includes a set of states representing possible conditions the work machine may encounter between starting at a zero energy input and being ready to work.
Claims18
A system for controlling a work machine, including an electric continuously variable transmission (CVT), the system comprising:
- a microprocessor, wherein the microprocessor is configured to include a state machine for controlling the behavior of the work machine, and
- wherein the state machine includes a set of states representing possible conditions the work machine may encounter between starting at a zero energy input and being ready to accept operator inputs.
A method for controlling initialization of a work machine having an electric continuously variable transmission (CVT), comprising:
- providing a state machine;
- determining a current state of the work machine;
- obtaining status information about the work machine;
- determining if criteria to jump to a new state are met, based on the state machine and the status information;
- and
- providing instructions to the work machine to effect behavior of the work machine required by the new state if the criteria are met.
