摘要： Provided are gearboxes including compound planet gear assemblies as well as methods of using such gearboxes. A gearbox includes at least a first ring gear and a second ring gear. Depending on the current gear selection, one of these ring gears may be engaged with a shifting mechanism or not engaged with any ring gears when in a neutral gear. The first ring gear may be constantly engaged with a first planet gear of a compound planet gear assembly, while the second ring gear may be constantly engaged with a second planet gear of the same compound planet gear assembly. The first planet gear may be also engaged with a sun gear coupled to a shaft. Another shaft is coupled to the shifting mechanism. Different gear selections of the gearbox engage different ring gears to the shifting mechanism thereby changing the rotational speed ratio of the two shafts.

摘要： An electronic control unit is configured to control a hydraulic pressures of engaging element and disengaging element in accordance with a preset target output shaft torque during a power-on downshift. The electronic control unit is configured to delay a start of decrease in the hydraulic pressure of the disengaging element from a start of a torque phase while maintain the hydraulic pressure of the disengaging element at the start of the torque phase. The electronic control unit is configured to start decreasing the hydraulic pressure of the disengaging element when the electronic control unit determines that overspeed of an input shaft is occurring during the torque phase and a predetermined condition is established.

摘要： A vehicle includes an engine, a transmission having a friction clutch and a binary clutch assembly, and a controller. The controller executes a method to detect the requested shift of the transmission to neutral, and when a set of conditions are satisfied during the requested shift, to automatically decrease a pressure command to the friction clutch such that torque capacity of the friction clutch decreases from a full torque capacity and begins to slip. The controller holds the binary clutch assembly at a calibrated pressure while the friction clutch slips, disengages the binary clutch assembly only when the binary clutch assembly is released and not loaded, and increases the pressure command to the friction clutch to restore full torque capacity to the friction clutch and complete the requested shift to neutral.

摘要： A method of commanding a synchronous gear shift begins by receiving a request to shift from a third gear to a first gear, and skipping a second gear having a gear ratio between the gear ratio of the first gear and the gear ratio of the third gear. Subsequently the method includes: reducing a torque command to a predetermined value; opening a clutch disposed on the input shaft of the transmission to decouple the transmission from the engine; transitioning the engine from a torque-control mode into a speed-control mode; commanding the engine to rotate at a speed dictated by the motion of the vehicle and the gear ratio of the first gear; closing the clutch to couple the transmission and the engine; and transitioning the engine back into the torque-control mode.

摘要： A power transmitting device makes a motor in a hybrid vehicle be smaller and lighter, prevents internal resistance and inertia of the generator motor from becoming driving resistance, and can effectively utilize energy. Via a first clutch, power is transmitted from an input shaft to a transmission shaft but power transmission vice versa is blocked, and power transmission from the input shaft to the transmission shaft can be blocked. Via a second clutch, power is transmitted from the transmission shaft to the input shaft, while power transmission vice versa is blocked. Thus, when driving using only the power of the engine, power transmission from the input shaft to the transmission shaft is blocked, thereby preventing transmission of power to the generator motor. Consequently, the generator motor can be made smaller and lighter, and energy losses can be prevented.

摘要： A method of operating a vehicle drive train with a drive machine and a transmission device during a coasting upshift, during which at least one interlocking shift element that is engaged in the force flow of the transmission device, to produce the gear ratio to be disengaged, is disengaged from the force flow, and a frictional shift element that has to be engaged, in the force flow of the transmission device to obtain the gear ratio to be engaged, is engaged in the force flow. When a shift command is given for a gear ratio change, torque applied at the interlocking shift element to be disengaged is reduced to at least approximately zero, by a defined engine intervention, and the interlocking shift element is then disengaged from the force flow of the transmission device.
