    • A shift device for an automatic transmission generates no manual shift demand in response to a plurality of operator shift demands. A steering wheel has an up-down select switch. A range selector has an upshift switch and a downshift switch in addition to an automatic mode switch. An operator shift demand may be generated through any one of the steering mounted switches and the select lever. A control unit has an operator upshift demand input terminal and an operator downshift demand input terminal. The control unit has a circuit that generates a two-level up signal and a circuit that generates a two-level down signal. The up signal has an “OFF” level indicative of absence of an operator upshift demand on the operator upshift demand input terminal. It has an “ON” level indicative of presence of an operator upshift demand on the operator upshift demand input terminal. The down signal has an “OFF” level indicative of absence of an operator downshift demand on the operator downshift demand terminal. It has an “ON” level indicative of presence of an operator downshift demand on the operator downshift demand input terminal. The control unit has software, which generates an upshift demand upon a rise in level of the up signal to “ON” level if the down signal is at “OFF” level. This software enables the control unit to generate a downshift demand upon a rise in level of the down signal to “ON” level if the up signal is at “OFF” level.
    • 用于自动变速器的换档装置响应于多个操作者换档要求而不产生手动变速需求。 方向盘有一个上下选择开关。 除了自动模式开关之外,量程选择器还具有升档开关和降档开关。 可以通过转向安装的开关和选择杆中的任何一个产生操作员换档要求。 控制单元具有操作者升档需求输入端子和操作者降档需求输入端子。 控制单元具有产生二电平上升信号的电路和产生二电平信号的电路。 上升信号具有“OFF”电平,表示操作者升档需求输入端没有操作者升档需求。 它具有“ON”电平,指示操作者升档需求输入端子上存在操作者升档需求。 降档信号具有“OFF”电平,表示操作者降档需求端子没有操作者降档需求。 它具有“ON”电平,指示操作者降档需求输入端子存在操作者降档需求。 控制单元具有软件,如果下降信号处于“关闭”电平,则在上升信号电平上升到“接通”电平时产生升档需求。 如果上升信号处于“关闭”电平,该软件使得控制单元能够在下降信号的电平上升到“开”电平时产生降档需求。

    • A shift mode selector for an automatic transmission of a vehicle drive train including an engine, includes a first shift point map for an automatic shift in an automatic shift mode and a second shift point map in a manual shift mode. An input device produces an operator mode change demand from the manual shift mode to the automatic shift mode. A controller determines whether or not a potential downshift demand is available upon effecting a mode change demanded by said operator mode change demand. The controller prohibits the mode change when said potential downshift demand is available, and produces a gear ratio control signal in accordance with the second shift point map unless a predetermined condition is met. The gear ratio control signal is applied to a gear ratio actuator for establishing various gear ratios in the automatic transmission.

    • A torque converter lock-up clutch controlling system for a vehicle drive train inputs a vehicle speed signal and an engine load signal. The vehicle drive train includes an automatic transmission operable in a manual ("M") ratio change mode when an operator selects a "M" range position. The system enables the automatic transmission to behave like a manual transmission upon selection of the "M" range position. A memory includes a "M" range lock-up shift point map for storing data which relates the lock-up application and release to the vehicle speed and engine load signals. The "M" range lock-up shift point map includes lock-up application values, which correspond to the magnitudes of the vehicle speed signal at which lock-up clutch applications are to occur. The magnitudes of the vehicle speed signal at which lock-up clutch applications are to occur are determined in a manner as a function of the magnitudes of the engine load signal. The "M" range lock-up shift point map includes a lock-up release value which corresponds to the magnitude of the vehicle speed signal at which lock-up clutch releases are to occur regardless of the magnitudes of the engine load signal. A controller receiving the vehicle speed and engine load signals, retrieves data from the "M" range lock-up shift point map and processes the retrieved data to produce a lock-up signal. A lock-up actuator controls the toque converter lock-up clutch in response to the lock-up signal.
    • 用于车辆传动系的变矩器锁止离合器控制系统输入车速信号和发动机负载信号。 当驾驶员选择“M”范围位置时,车辆传动系包括以手动(“M”)比变化模式操作的自动变速器。 该系统能够在选择“M”范围位置时使自动变速器像手动变速器一样工作。 存储器包括用于存储将锁定应用和释放与车辆速度和发动机负载信号相关联的数据的“M”范围锁定移位点图。 “M”范围锁定换档点图包括锁定应用值,其对应于将要发生锁止离合器应用的车速信号的大小。 以发动机负载信号的大小的函数的方式确定要发生锁止离合器应用的车速信号的大小。 “M”范围锁定换档点图包括与发动机负载信号的大小无关地发生锁定离合器释放的车速信号的大小对应的锁定释放值。 接收车速和发动机负载信号的控制器从“M”范围锁定移位点图检索数据,并处理检索到的数据以产生锁定信号。 锁定执行器响应于锁定信号控制转矩锁定离合器。
