Document Type and Number:
Japanese Patent JPH11514947
Kind Code:
A
Abstract:
A drive train for a vehicle having front and rear wheels includes a fluidic motor and a pump interconnected in a continuous loop, with one conduit connected to the inlet of the fluidic motor to the outlet of the pump and a second conduit connecting the inlet of the pump to the outlet of the fluidic motor. A gas/liquid fluid accumulator is in fluid communication with the first conduit and a low pressure reservoir is in fluid communication with the second conduit. An engine, sized to match the average torque demanded of the vehicle, is employed to drive the pump. Sensors are included for detecting the pressure within the accumulator and the power demanded of the vehicle by the driver and, optionally, vehicle speed. A motor controller controls displacement of the fluidic motor in accordance with the sensed power demand and a pump controller controls displacement of the pump responsive to the signal for detected pressure.
