Patent ID: 8615336

Claim:
A system for controlling power of a hybrid vehicle, the hybrid vehicle comprising a power source, a generator, and an energy storage device, the system comprising; a controller configured to: receive a signal indicative of a commanded acceleration for the hybrid vehicle; determine a potential for each of the power source, the generator, and the energy storage device to supply energy to achieve the commanded acceleration; determine a cost associated with using cacti of the power source, the generator, and the energy storage device to achieve the commanded acceleration; determine a combination of the power source, the generator, and the energy storage device that achieves the commanded acceleration at a lowest total cost; and provide a signal to at least one of the power source, the generator, and the energy storage device to achieve the commanded acceleration based on the determined combination, wherein the cost associated with use of the energy storage device to assist with achieving the commanded acceleration is based on a first level of energy stored in the energy storage device and an estimated amount of time required to restore energy to the energy storage device to the first level of stored enemy if the energy of the energy storage device is used to assist with achieving the commanded acceleration.
