摘要： A shift control method for an automated manual transmission is provided. The method includes the step of modulating the force applied to a shift collar, via a shift rod and/or shift fork for example, during the engagement of the shift collar and a selected gear. The method modulates the initial engagement force applied to the shift collar when the rotational speed differential between the collar and gear is being adjusted, before increasing the force again following modulation. This modulation of the force decelerates the shift collar during the rotational speed adjustment and does not accelerate the shift collar to complete the engagement until after the modulation. In this way, a less abrupt engagement of the gear may be achieved. The control method may improve the driving characteristics of the vehicle employing the transmission and may also improve the power transmission efficiency.
摘要翻译： 提供了一种用于自动手动变速器的变速控制方法。 该方法包括在换档轴环和选定齿轮的接合期间通过换档杆和/或换档拨叉来调节施加到换档轴环的力的步骤。 当在调节之后再次增加力时，该方法调节在轴环和齿轮之间的转速差异被调整时施加到换档套环的初始接合力。 该力的调制在转速调节期间使换档轴环减速，并且不会加速换档轴环以完成接合，直到调制之后。 以这种方式，可以实现齿轮的较不突然的接合。 该控制方法可以提高使用变速器的车辆的驾驶特性，并且也可以提高动力传递效率。

摘要： Transmissions in which the mechanical gear shift arrangements are replaced by electro-hydraulic operated shift mechanisms that have to be able to be neutralised positively to ensure a proper operation. An arrangement and method are provided to determine the position of the shift rail so a shift can be made only if the conditions are right. To prevent engagement of two shift members at the same time and consequent damage in case of electronic failure, mechanical safety features such as detents are included.
