Patent ID: 8823204

Claim:
An electric load system for a vehicle that prevents the need for large and expensive electric load detector comprising: an electrically driven element operating in a plurality of operating states and a plurality of voltage modes thereby generating an electric load; a plurality of electric devices; wherein the plurality of electric devices are separate from the electrically driven element and the plurality of electric devices generates an electric load that is separate from the electric load generated by the electrically driven element; an electric load detector utilized to measure the electric load generated by a plurality of electric devices that is separate from the electric load generated by the electrically driven element; and an electric control unit utilized to estimate the electric load of the electrically driven element that is separate from the electric load of the plurality of electric devices; wherein the electric control unit evaluates a current operating state from a plurality of operating states and a current voltage mode from the plurality of voltage modes to estimate the electric load generated by the electrically driven element, and wherein the electric control unit communicates with the electric load detector and adds the electric load measured by the electric load detector and the electric load generated by the electrically driven element as estimated by the electric control unit to determine a total electric load.
