Abstract
An exemplary method for operating a hybrid vehicle in the event that there is a problem with an auxiliary power source, such as an internal combustion engine or a fuel cell. According to one embodiment, the method provides a power management scheme for a variety of situations where an auxiliary power source experiences a problem; this may include situations where an internal combustion engine runs out of fuel, where there is a mechanical or electrical malfunction, or any other instance where the auxiliary power source is unable to generate and/or provide electrical energy for the hybrid vehicle. The power management scheme conserves the vehicle's primary power source, which is typically a battery, in order to provide the hybrid vehicle with an extended driving range.
