Abstract:
In one aspect of the present invention, a method for determining the work cycle of an earth moving machine is disclosed. The machine has a transmission, a work implement, and a lift cylinder and a tilt cylinder connected to the work implement. The method includes the steps of determining a lift cylinder head end pressure, a displacement of the lift cylinder, a displacement of the tilt cylinder, and a direction of travel of the machine. The method further includes determining the work cycle of the machine in response to the displacement of the tilt and lift cylinders, and the lift cylinder head end pressure.
