摘要： A static hydraulic continuously variable transmission includes a fixed capacity swash type hydraulic pump and a variable capacity swash type hydraulic motor, connected by a hydraulic closed circuit. A control system and method controls hydraulic pressure in the variable transmission, and thereby reduces the likelihood of noise in the variable transmission under certain driving conditions. The hydraulic pressure is controlled by changing the inclination angle of a movable swash plate. The driving conditions which prompt the control system may include: (1) A signal voltage of a throttle sensor indicates the throttle opening is lower than a first threshold value; (2) A vehicle speed is over a second threshold value; (3) An acceleration is over a third threshold value; (4) An engine speed is below a fourth threshold value; and (5) Conditions (1) through (4) last for a predetermined period of time.

摘要： A method to provide a smooth shift during mode changes of an HMT when using mechanical clutches by reducing the power into the transmission momentarily when a shift is initiated by cutting fuel to the engine, and also reducing power in the hydrostatic transmission by crossporting the fluid circuit, and then reapplying power to both the engine and the transmission after the clutch has been shifted.

摘要： The invention eliminates the feeling of two-phase speed-change operations by causing a speed-change operation to proceed continuously when the speed-change operation is performed through two-phase control of engagement and release of four engagement elements. An automatic transmission is such that a predetermined speed-change operation is achieved through a pre-phase speed-change operation in which a first engagement element and a third engagement element are released and engaged respectively and through a post-phase speed-change operation in which a second engagement element and a fourth engagement element are released and engaged respectively. A control apparatus has a torque control capability for adjusting an input torque of a transmission during the pre-phase speed-change control, and ensures continuous changes in the input speed during the pre-phase and post-phase speed-change operations through adjustment of the input torque (torque reduction) to prevent bluntness from being caused between the pre-phase and post-phase speed-change operations.
摘要翻译：本发明通过使四个接合元件的接合和释放的两相控制进行变速操作时，通过使变速操作连续进行来消除两相变速操作的感觉。自动变速器是这样的，即通过预分相变速操作实现预定的变速操作，其中第一接合元件和第三接合元件分别被释放和接合，并且通过后相变速操作第二接合元件和第四接合元件分别被释放和接合。控制装置具有用于在预相变速控制期间调整变速器的输入转矩的转矩控制能力，并且通过调整前期和后期变速操作来确保在前期和后期变速操作期间的输入速度的连续变化输入转矩（转矩降低），以防止在前相和后相变速操作之间引起钝化。

摘要： A transmission assembly driven by an engine is disclosed. The transmission assembly includes a hydrostatic transmission having a variable displacement hydraulic pump and a hydraulic motor, a mechanical transmission coupled to the hydrostatic transmission for selecting a first gear range and a second gear range, and a controller for receiving operator inputs and generating a displacement command operable to control a displacement of the variable displacement pump. The controller determines the actual displacement. The controller determines a displacement shift level from the actual displacement. The controller executes a shift from the first gear range to the second gear range when the actual displacement reaches displacement shift level. A method of controlling a transmission assembly is also disclosed.
