摘要： A method for controlling a transmission in a motor vehicle during acceleration from an idle condition begins when the vehicle is stationary, the engine is at idle, and the transmission is in the first gear range or ratio. When the vehicle begins to accelerate, the method includes the steps of monitoring the rate of vehicle acceleration and comparing the rate of vehicle acceleration to a rate of vehicle acceleration threshold. If the rate of vehicle acceleration is less than the acceleration threshold, then the transmission allows one of the currently engaged clutches to slip. This clutch slip reduces the torque load on the engine. The method then monitors the engine output speed. If the engine output speed exceeds an engine output speed threshold, then the clutch is fully applied.

摘要： One or more friction devices of a transmission coupled to an engine through a fluid coupling are used during engine neutral idle operation to control the state of the fluid coupling for synchronous engagement and disengagement of a PTO input gear with a transmission-driven gear. The fluid coupling includes an input member connected to the engine and an output member connected to the input shaft of the transmission, and the transmission friction devices temporarily ground the output member without mechanically coupling the transmission input and output shafts under specified enable conditions. This maintains the transmission input shaft in a stationary condition while an actuator engages or disengages the PTO input gear with the transmission-driven gear. Following engagement or disengagement of the PTO input gear, the friction devices are released to resume normal operation of the fluid coupling.
摘要翻译：在发动机空载怠速运转期间，使用通过流体联轴器联接到发动机的变速器的一个或多个摩擦装置来控制流体联轴器的状态，以便PTO输入齿轮与变速器从动齿轮的同步接合和分离。流体联轴器包括连接到发动机的输入构件和连接到变速器的输入轴的输出构件，并且变速器摩擦装置暂时将输出构件接地而不在特定使能条件下机械地联接变速器输入和输出轴。这将传动输入轴保持在静止状态，同时致动器将PTO输入齿轮与传动从动齿轮接合或脱离。在PTO输入齿轮的接合或分离之后，释放摩擦装置以恢复流体联轴器的正常操作。
