The invention provides a hydraulic hybrid vehicle control method. The method comprises the following steps that: when the running speed of a vehicle is greater than zero, the angular displacement of abrake pedal is greater than zero and less than a first brake angular displacement set value, a controller controls a valve set connected to a hydraulic pump/motor to act, the displacement of the hydraulic pump/motor is larger than zero, rotating wheels drive the hydraulic pump/motor to act, and hydraulic oil in a second energy accumulator is pressurized by the hydraulic pump/motor and then flowsinto a first energy accumulator; when the angular displacement of an accelerator pedal is greater than zero and less than a first accelerator angular displacement set value, the controller controls the valve set to act, the displacement of the hydraulic pump/motor is larger than zero, hydraulic oil in the first energy accumulator flows into the second energy accumulator through the hydraulic pump/motor, the hydraulic oil in the first energy accumulator drives the hydraulic pump/motor to act, and the hydraulic pump/motor drives the wheels to rotate. By means of the hydraulic hybrid vehicle control method, braking energy is recycled and utilized, and low energy consumption of the vehicle is guaranteed.

    本发明提供一种液压混合动力车辆控制方法,包括如下步骤:当车辆的行驶速度大于零,刹车踏板的角位移大于零且小于第一刹车角位移设定值,控制器控制与液压泵/马达相连接的阀组动作,液压泵/马达的排量大于零,转动中的车轮带动液压泵/马达动作,第二蓄能器中的液压油经该液压泵/马达加压后流入第一蓄能器中;当油门踏板的角位移大于零且小于第一油门角位移设定值,控制器控制阀组动作,液压泵/马达的排量大于零,第一蓄能器中的液压油经液压泵/马达流入第二蓄能器中,且第一蓄能器中的液压油驱动液压泵/马达动作,液压泵/马达驱动车轮转动。本液压混合动力车辆控制方法实现了制动能的回收及利用,并保证车辆耗能较低。
