Method, apparatus, signals, and medium for managing power in a hybrid vehicle
First Claim
1. A method for managing power in a hybrid vehicle, the vehicle comprising an engine, an electric motor, and an energy storage element coupled to the motor, the method comprising:
- receiving a request to supply operating power to drive the vehicle;
responding to said request by selecting an apportionment of operating power between the engine and the motor from among a plurality of apportionments having respective operating costs, such that said selected apportionment is associated with a minimum operating cost, said operating cost comprising at least an engine fuel consumption cost and a storage element lifetime cost; and
causing power to be supplied by at least one of the engine and the motor in accordance with said selected apportionment.
