    • A control method/system for controlling the operation of an electric motor (32, 42) actuated shifting mechanism (28) is provided, which includes a procedure for periodically relieving trapped frictional forces in the shifting mechanism and associated linkages (30, 38, 40). At initiation of a shifting operation (60), or periodically (66) during a shifting operation, the level of energization of the electric motor is reduced from the full target energization level thereof (68) to a minimal level (70) for a relatively short period of time (72) and then returned to the target energization level thereof. Preferably, the level of energization is returned in a 2-step process comprising stepping the level of energization to an intermediate level (76) and then ramping the level of energization from the intermediate value to the level of full target energization thereof in a ramped fashion.
    • 提供了一种用于控制电动机(32,42)致动换挡机构(28)的操作的控制方法/系统,其包括用于周期性地释放换档机构中的被困的摩擦力和相关联的联动装置(30,38,40 )。 在变速操作(60)或在变速操作期间周期性地(66)开始时,相对于电动机的通电水平从其全目标通电水平(68)降低到最小水平(70) 短时间(72),然后恢复到目标通电水平。 优选地,激励水平以两步过程返回,包括将通电电平梯级到中间电平(76),然后以渐变的方式将通电电平从中间值斜升到完全目标通电的水平 。

    • A control system (104)/method for semi-automatically executing automatically and manually selected upshifts and downshifts of a mechanical transmission system (10) is provided. The control system includes a central processing unit (106) for receiving input signals indicative of transmission input shaft (16) and output shaft (90) speeds and from a driver control console (108) and processing the same in accordance with predetermined logic rules to issue command output signals to a transmission actuator (112, 70, 96) to implement the selected shifts. The control is effective to initiate a shift by automatically preselecting a shift from the currently ratio into neutral and to then await a manually caused torque break of the transmission to complete the shift to neutral. The control is effective to minimize wear by issuing repetitive shift prompts if transmission neutral is not sensed within predetermined times from preselection of a shift frown a currently engaged ratio (GR) into neutral(N).
    • 提供一种用于半自动执行机械传动系统(10)的自动和手动选择的升档和降档的控制系统(104)/方法。 控制系统包括中央处理单元(106),用于接收表示变速器输入轴(16)和输出轴(90)速度的输入信号和来自驾驶员控制台(108)并根据预定的逻辑规则对其进行处理 向传动致动器(112,70,96)发出命令输出信号以实现所选择的换档。 该控制通过自动地将当前比率的换档预先选择为空档,然后等待手动引起的变速器的扭矩中断以完成向中性的转换而有效地启动换档。 如果在从预先选择当前接合比(GR)变为中立(N)的班次的预定时间内没有感测到传动空档,则控制通过发出重复的换档提示而有效地最小化磨损。
