System And Method For Displaying Power Flow In A Hybrid Vehicle
First Claim
1. A method of displaying component icons and a graphical representation of power flows between pairs of the component icons in a hybrid vehicle, the component icons representing components of the hybrid vehicle including an engine, a battery, drive wheels, and an electric machine arrangement having an electric motor and an electric generator, the method comprising:
- determining a mode of operation of the hybrid vehicle;
processing powertrain signals to obtain a torque value and a speed value based on the mode of operation, the torque and speed values representing respective torque and speed of at least one of the electric motor and the electric generator;
calculating magnitude and direction of power flow between the electric machine arrangement and at least one of the engine and the drive wheels based on the torque and speed values; and
displaying the component icons and a graphical representation of the power flow, wherein the graphical representation is between at least one pair of the component icons and represents the magnitude and the direction of the power flow.
