    摘要: A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. Each driven wheels is driven by a hydraulic motor with a continuous adjustment of the motor displacement, with the motor being driven by a pump also having continuous displacement. The motor displacement is controlled by an electronic controller in response to stroking of the speed control lever to manage the displacement to provide required drive torques at different points in the stroke. There is provided an automatic steering system having a guidance controller arranged to receive GPS position information which controls the steering by differentially adjusting the displacement of the motors so that the automatic steering is independent of the manual steering which controls the pumps.

    摘要: An inverted pendulum type vehicle has a first travel operation unit and a second travel operation unit. A controller of the inverted pendulum type vehicle controls an actuator on the basis of a restricted desired value. The restricted desired value is obtained by restricting a basic desired value of the lateral travel velocity of the second travel operation unit by a limiting processor, the basic desired value being for bringing the actual turn angular velocity of the vehicle close to a desired value. The limit width of the limiting processor is variably set according to the actual travel velocity of the second travel operation unit.

    摘要: A fluid controller (15a) in a multiple-input hydrostatic power steering system includes a check valve assembly (101), having a first fluid passage (111), defining a check valve seat (105) and a check valve (103) operably associated therewith, in fluid communication with a second fluid passage (109), with the second fluid passage (109) being in fluid communication with a return port (25a). In the left (L) and right (R) operating positions, return flow can flow from the interior region (114) of the valve (27), through the first fluid passage (111), past the check valve (103), and through the second fluid passage (109) to the return port (25a). In the neutral position (N), pressurized fluid can flow from an inlet port (19a) to the return port (25a), with the check valve (103) preventing fluid from flowing through the first fluid passage (111) and into the interior region (114) of the valve (27).
