The disclosure pertains to a hybrid electric hydraulic motor system for a vehicle having a propulsion mode and a decelerating mode. The system generally includes one or more batteries for storing electricity; an electric motor operably connected to the battery; an internal combustion engine; a vehicle hydraulic system; a first hydraulic pump operably connected to the electric motor for producing hydraulic pressure; a first hydraulic motor operably connected between the first hydraulic pump and the internal combustion engine; a timer valve operably connected between the first hydraulic pump and the first hydraulic motor; a second hydraulic pump operably connected to the internal combustion engine for producing hydraulic pressure; a hydraulic reservoir for storing hydraulic liquid operably connected to the first hydraulic pump, the second hydraulic pump, and the third hydraulic pump; a second hydraulic motor operably connected to the first and second hydraulic pumps; and a motive device operably connected to the second hydraulic motor. While in the ignition stage of the propulsion mode of the system, the battery provides electricity to drive the electric motor which drives the hydraulic pump which provides hydraulic pressure to the first hydraulic motor which operates to start the internal combustion engine, wherein after ignition of the internal combustion engine, the timer valve operates to discontinue hydraulic pressure between the first hydraulic pump and the second hydraulic pump. While in the drive stage of the propulsion mode after and after ignition of the internal combustion engine, the internal combustion engine operates to drive the second hydraulic pump, wherein the first hydraulic pump and the second hydraulic pump operably combine to supply the second hydraulic motor with hydraulic pressure to drive the motive device.
