A propulsion system for use in a hybrid vehicle, wherein a first propulsion system provides a driving force to a first pair of wheels and a second propulsion system provides a driving force to a second pair of wheels. A system controller actuates the propulsion systems determines the necessary commands to be provided to the first and second propulsion systems so as to provide the vehicle with the most efficient driving and/or stopping force.

1. A hybrid vehicle having a state of charge control system for the hybrid vehicle's energy source, comprising:a) a first propulsion system being configured and positioned to provide a driving force to a first pair of wheels; b) a second propulsion system being configured and positioned to provide a driving force to a second pair of wheels; c) a second propulsion system controller for actuating said second propulsion system; and d) a system controller for actuating said first propulsion system and providing command request to said second propulsion control system, said system controller utilizes a control algorithm for determining the necessary commands to be provided to said first and second propulsion systems so as to provide said hybrid vehicle with a continuous driving force, said control algorithm utilizes an input of the current state of charge of an electrical source for determining the necessary commands, said control algorithm determining if said input is greater than a first value if so, said control algorithm instructs said first propulsion system to provide said driving force to said first pair of wheels via said power supplied from said electrical source in response to a driver's request and all other vehicle systems are also powered by said electrical source; if said input is less than said first value and greater than a second value, then said control algorithm instructs said second propulsion system to provide a supplemental electrical charge to said electrical source and supply light acceleration and cruising powered demands of said vehicle; if said input is less than said second value and greater than a third value then said control algorithm instructs said second propulsion system to provide a supplemental electrical charge to said electrical source and said second propulsion system provides heavy acceleration power demands of said vehicle; if said input is less than said third value and greater than a fourth value, then said control algorithm instructs said second propulsion system to continuously charge said electrical source; and if said input is less than said the fourth value then said control algorithm disconnects all non-essential electrical loads from electrical source.
