    • An apparatus and method for controlling the rate of engagement of a clutch in response to an indication provided by the driver, such as the depression of an accelerator pedal of the vehicle. The apparatus includes an electronic controller which initially determines a start rate as the minimum duty cycle which is required to modulate an engage valve in order to cause movement of a release bearing of the clutch in the engagement direction. The start rate is determined by initially moving the release bearing to the disengaged position. Then, the engage valve is incrementally modulated until the release bearing begins moving in the engaged direction from the disengaged position. When a predetermined amount of such movement has been detected, the electronic controller sets the start rate as the current duty cycle of the engage valve. The electronic controller is also responsive to an excessive amount of overshooting movement of the release bearing when attempting to position it in a desired position for reducing the start rate.
    • 一种用于响应于驾驶员提供的指示(例如车辆的加速器踏板的按压)来控制离合器的接合速率的装置和方法。 该装置包括一个电子控制器,该电子控制器最初将启动速率确定为调节接合阀所需的最小占空比,以使离合器的释放轴承沿接合方向移动。 起始速率通过将释放轴承初始移动到脱离位置来确定。 然后,接合阀被增量调制,直到释放轴承从接合方向开始从脱离位置移动。 当检测到预定量的这种运动时,电子控制器将启动速率设定为接合阀的当前占空比。 当试图将其放置在期望的位置以减小启动速率时,电子控制器还响应于释放轴承的过量的过冲运动。

    • An apparatus and method for controlling the engagement rate of a clutch in a partially or fully automated mechanical transmission are responsive to certain calculations derived from the rotational speeds of the input member and the output member of the clutch. The apparatus includes an electronic controller which initially sets a desired speed for the vehicle engine during the shifting process, determines a rate of engagement movement of a release bearing of the clutch, and actuates appropriate valves to initiate the gradual engagement of the clutch. In a first embodiment, the electronic controller compares the rotational speeds of the input and output shafts of the clutch in order to determine if the difference therebetween is less than a first constant value. If so, it can be inferred that the clutch is sufficiently close to full engagement as to warrant the interruption of the gradual engagement process and immediately move the release bearing from its current position to the fully engaged position. To avoid a false inference of full engagement, the clutch input or output shaft speed signal is compared with the desired engine speed signal. When the magnitude of the difference between the clutch input shaft speed signal and the desired engine speed signal is less than a second constant value, then the inference that the clutch is sufficiently close to full engagement is confirmed. Thus, the release bearing can be immediately moved from its current position to the fully engaged position. In a second embodiment, an updated difference signal (calculated as the difference between an updated clutch input shaft speed signal and an updated clutch output shaft speed signal) is compared with a previous difference signal. An error signal is calculated as the difference between the updated difference signal and the previous difference signal. The electronic controller controls the movement of the release bearing such that the error signal closely follows a selected clutch engagement profile so as to consistently engage the clutch.
    • 用于控制部分或全自动机械变速器中的离合器的接合速率的装置和方法响应于从离合器的输入构件和输出构件的转速得到的某些计算。 该装置包括电子控制器,其在换档过程期间初始设定车辆发动机的期望速度,确定离合器的释放轴承的接合运动速率,并且启动适当的阀以启动离合器的逐渐接合。 在第一实施例中,电子控制器比较离合器的输入和输出轴的转速,以便确定它们之间的差值是否小于第一常数值。 如果是这样,可以推断离合器足够接近完全接合,以保证逐渐接合过程的中断,并立即将释放轴承从其当前位置移动到完全接合位置。 为了避免完全啮合的错误推断,将离合器输入或输出轴速度信号与期望的发动机转速信号进行比较。 当离合器输入轴速度信号与期望的发动机转速信号之间的差值的大小小于第二常数值时,确认离合器足够接近完全接合的推断。 因此,释放轴承可以立即从其当前位置移动到完全接合位置。 在第二实施例中,将更新的差分信号(作为更新的离合器输入轴速度信号和更新的离合器输出轴速度信号之间的差计算)与先前的差分信号进行比较。 误差信号被计算为更新的差分信号和先前差分信号之间的差。 电子控制器控制释放轴承的运动,使得误差信号紧跟选定的离合器接合轮廓,以一致地接合离合器。

    • An apparatus and method for controlling the engagement rate of a clutch in a partially or fully automated mechanical transmission in response to an indication provided by the driver, such as the depression of an accelerator pedal of the vehicle. The apparatus includes an electronic controller which initially sets a desired speed for the vehicle engine during the shifting process, determines a rate of engagement movement of a release bearing of the clutch, and actuates appropriate valves to initiate the gradual engagement of the clutch. The electronic controller is responsive to the position of the accelerator pedal of the vehicle for adjusting the rate of engagement of the release bearing of the clutch. In a first embodiment, the electronic controller is responsive to movement of the accelerator pedal in a first direction (depressed for further acceleration) for incrementing the rate of engagement of the release bearing. Similarly, the electronic controller is responsive to movement of the accelerator pedal in a second direction (release for further deceleration) for decrementing the rate of engagement of the release bearing. If the accelerator pedal is maintained in a constant position, the rate of engagement of the release bearing is unchanged. In a second embodiment, the electronic controller is responsive to rate or amount of movement of the accelerator pedal in the first direction for incrementing the rate of engagement of the release bearing, similarly, the rate or amount of movement of the accelerator pedal in the second direction for decrementing the rate of engagement of the release bearing.
    • 一种用于响应于由驾驶员提供的指示(例如车辆的加速器踏板的按压)来控制部分或全部自动机械变速器中的离合器的接合率的装置和方法。 该装置包括电子控制器,其在换档过程期间初始设定车辆发动机的期望速度,确定离合器的释放轴承的接合运动速率,并且启动适当的阀以启动离合器的逐渐接合。 电子控制器响应车辆的加速器踏板的位置,以调节离合器的释放轴承的接合速率。 在第一实施例中,电子控制器响应于加速踏板在第一方向上的移动(按压以进一步加速),以增加释放轴承的接合速率。 类似地,电子控制器响应于加速踏板在第二方向上的移动(释放进一步减速),以减小释放轴承的接合速率。 如果加速器踏板保持在恒定位置,则释放轴承的接合速率不变。 在第二实施例中,电子控制器响应加速踏板在第一方向上的速度或运动量,以增加释放轴承的接合速率,类似地,加速踏板在第二方向上的速度或移动量 减小释放轴承接合速度的方向。
