A hybrid vehicle drive system for a vehicle includes a first prime mover, a first prime mover driven transmission, and a rechargeable power source. The hybrid vehicle drive system further includes an interface between the transmission and the prime mover for coupling to an electric motor. The electric motor can be in direct or indirect mechanical communication with a hydraulic pump. The electric motor can receive power from the prime mover driven transmission through the interface.

1. A method of retrofitting a vehicle power drive system, the vehicle power drive system comprising an internal combustion engine connected through a transmission to drive wheels of the vehicle, said transmission having a power take off (PTO), the method comprising: connecting an electric motor and a hydraulic pump to the PTO via a through shaft, the through shaft being provided through one of the hydraulic pump or the electric motor; andproviding a vehicle monitoring and control system (VMCS) and an energy storage system for the electric motor to form a parallel drive system, wherein the VMCS controls the parallel drive system to recharge the energy storage system. 2. The method of claim 1, wherein the PTO is connected to a torque converter in the transmission. 3. The method of claim 2, wherein the VMCS interfaces with an original equipment manufacturers (OEM) vehicle data system in order to eliminate or reduce regenerative braking based on anti-lock or traction control. 4. The method of claim 1, wherein the VMCS monitors accelerator pedal position, engine throttle position, battery voltage, vehicle speed, and torque request to determine amount and frequency of power being applied to the PTO for maintaining vehicle drivability and optimizing overall efficiency, and wherein the transmission shifts through each gear, the transmission provides a signal over a vehicle network to the VMCS in order to provide an advanced notice of a shift event, wherein the VMCS receives the signal providing the advanced notice of the shift event and based upon the signal and the pedal position can increase or decrease the power provided to the electric motor, allowing for smoother and more efficient shifting, thereby enhancing the vehicle ride and reducing fuel consumption. 5. The method of claim 1, wherein the VMCS monitors accelerator pedal position, engine throttle position, battery voltage, vehicle speed, and torque request to determine amount and frequency of power being applied to the PTO for maintaining vehicle drivability and optimizing overall efficiency, and wherein the VMCS tunes the amount of power provided for launch assist and regenerative braking power applied in the forward and/or reverse direction, wherein further said VMCS has a tuning chart having a setting for each gear, the settings including pedal position vs. positive or negative torque applied, battery voltage vs. torque provided, torque provided vs. state of charge (SOC), and driver inputs including a system disable. 6. The method of claim 5 wherein the transmission shifts through each gear, wherein the transmission provides a signal over a vehicle network to the VMCS in order to provide an advanced notice of a shift event, wherein the VMCS receives the signal providing the advanced notice of the shift event and based upon the signal and the pedal position can increase or decrease the power provided to the electric motor, allowing for smoother and more efficient shifting, hereby enhancing the vehicle ride and reducing fuel consumption. 7. The method of claim 5, wherein the hydraulic pump is a load sense or variable displacement pump and the hydraulic pump is disposed in an end shaft configuration. 8. The method of claim 5, further comprising coupling an accessory device to the electric motor. 9. The method of claim 1, wherein the VMCS monitors accelerator pedal position, engine throttle position, battery voltage, vehicle speed, and torque request to determine amount and frequency of power being applied to the PTO for maintaining vehicle drivability and optimizing overall efficiency. 10. The method of claim 1 wherein the transmission shifts through each gear, wherein the transmission provides a signal over a vehicle network to the VMCS in order to provide advanced notice of a shift event, wherein the VMCS receives the signal providing the advanced notice of a the shift event and based upon the signal and the pedal position can increase or decrease the power provided to the electric motor, allowing for smoother and more efficient shifting, hereby enhancing the vehicle ride and reducing fuel consumption.
