The invention relates to a commercial vehicle AMT parking side power takeoff control method. The method comprises the steps that a gear signal and a hand brake signal are obtained, and if the gear signal is a neutral gear and the hand brake signal is a pull-up signal, a power takeoff request signal is obtained; if the request signal is open, a clutch is separated; a front auxiliary box is engagedwith a low gear; a power takeoff electromagnetic valve is activated; a power takeoff state signal is obtained, and if the power takeoff state signal is engagement, the clutch is combined; otherwise, afault is displayed; the operation exits; if the power takeoff request signal is off , the clutch is separated; the power takeoff electromagnetic valve is closed; the power takeoff state signal is acquired, and the fault is displayed if the power takeoff state signal is engagement; the operation exits; and otherwise, the operation exits normally. The control process is clear, and control is easy and convenient; the operation reliability is greatly improved; the gear shifting process is simple; and operation safety is greatly improved.
本发明涉及商用车AMT停车侧取力控制方法,包含步骤:获取档位信号、手刹信号,如档位信号为“空档”,且手刹信号为“拉起”,则获取取力器请求信号;如为“开启”,则离合器分离;前副箱挂入低档;激活取力器电磁阀;获取取力器状态信号,如为“啮合”,则离合器结合;否则显示“故障”;退出操作;如取力器请求信号为“关闭”,则离合器分离;关闭取力器电磁阀;获取取力器状态信号,如为“啮合”,则显示“故障”;退出操作;否则正常退出操作。本发明控制流程清晰,操控简单方便;操作可靠性大幅提升;换挡过程简便;操作安全性大幅提升。
