Abstract
A hybrid drive system for integrated vehicle stability control. Specifically, the hybrid drive system includes a multi-wheeled vehicle, a drop-in electric drive motor, and a master controller. The multi-wheeled vehicle is originally configured for propulsion using an internal combustion engine. That is, the present invention is suitable for powering legacy vehicles. The internal combustion engine capable of driving at least one wheel of the multi-wheeled vehicle. The remaining wheels of the multi-wheeled vehicle are not driven by the internal combustion engine. The drop-in electric drive motor is adapted to independently drive at least one remaining wheel on the multi-wheeled vehicle. The master controller is coupled to the drop-in electric drive motor. The master controller controls speeds of the remaining wheels driven by the electric drive motor to provide propulsion and overall stability management for the multi-wheeled vehicle.
