Abstract:
1. A hybrid motor vehicle, comprising: a vehicle body with drive wheels; an electrical storage battery mounted on board the vehicle body; a charging outlet located on board the vehicle body, for charging of the electrical storage battery, and configured to allow charging through being plugged into an off board charging source; an electric motor mounted on the vehicle body, for drawing energy from the electrical storage battery and driving the drive wheels for propulsion of the vehicle; an internal combustion engine mounted on the vehicle body, connected to an on-board liquid fuel tank, to combust the liquid fuel and generate power for use in the vehicle in the event of depletion of the electrical storage battery to a minimum threshold; a high pressure hydraulic accumulator mounted on the vehicle, configured to selectively store and release energy in the form of pressurized fluid; and a first hydraulic pump and a second hydraulic pump/motor, said first hydraulic pump configured to be driven by the internal combustion engine, for pressurizing fluid, and the second hydraulic pump/motor mechanically linked to the drive wheels and configured in motor mode to be driven by pressurized fluid to propel the vehicle when the electrical storage battery is depleted to the minimum threshold, and the second pump/motor further configured in pump mode to be driven by the kinetic energy of the vehicle to pressurize fluid for storage in the high pressure hydraulic accumulator.
