Claim:
1. An electro-hydraulic hybrid system that includes a braking mode and an acceleration mode of operation for use with a vehicle having a primary drive axle, the system comprises: an electronic control unit (ECU) that in response to receiving a brake pedal displacement value from the vehicle compares the value with a stored brake activation value and determinatively sends a brake application command and in response to receiving an accelerator pedal displacement value from the vehicle compares the value with a stored launch activation value and determinatively sends an accelerator application command; a power distribution unit; a hydraulic drive pump; at least one accumulator; a hydraulic reservoir; a hydraulic pump; an electric motor; a power converter; at least one battery; the hydraulic reservoir in fluid communication with the accumulator(s) through the hydraulic drive pump; the hydraulic reservoir in fluid communication with the accumulator(s) through the hydraulic pump; the hydraulic drive pump communicably coupled with the ECU and mechanically coupled with the primary drive axle of the vehicle, the hydraulic drive pump in response to receiving the brake application command transfers fluid from the hydraulic reservoir to the accumulator using energy from the drive shaft transitioning the system into the braking mode of operation and in response to receiving the accelerator application command transfers fluid from the accumulator(s) to the hydraulic reservoir supplying energy to the drive axle transitioning the system into the acceleration mode of operation; the electric motor being torsionally connected with the hydraulic pump; the at least one battery being electrically connected with the electric motor through the power converter; the ECU being electrically connected with the at least one battery; and the power distribution unit being electrically connected with the at least one battery.
