摘要： A control device for a transmission that has multiple shift stages and is configured to change an amount of power output from an engine of a vehicle for output includes a setting unit and a control unit. The setting unit is capable of setting, as a shift change mode, either one of a first shift change mode and a second shift change mode in which a speed of the engine is maintained in a higher state than that in the first shift change mode. The control unit is configured to execute shift change control on a basis of the set shift change mode. The control unit is configured to exclude one or more shift stages of the multiple shift stages and execute the shift change control when the second shift change mode is set.

摘要： A method is provided for controlling a multi-clutch transmission of a vehicle, wherein the clutch transmission is adapted to be shifted either with a power shift or a power cut shift dependent on predetermined vehicle variables. The method includes detecting a power shift to a higher gear in low range gear, wherein if power shift to a higher gear in low range gear has been detected the method overrules the previously set gear shift strategy and controls the multi-clutch transmission such that a forthcoming gear shift is performed as a power shift.

摘要： When there is a request for a skip downshift that transitionally establishes an intermediate speed position, a surge hydraulic pressure at the start of a torque phase during shift control toward the intermediate speed position is set so as to be lower than a surge hydraulic pressure at the start of a torque phase during shift control toward a required speed position.

摘要： In a controller for an automatic transmission, when a jump gear shift via a plurality of intermediate shift stages is executed, a first and a second target intermediate shift stages are extracted, and a target input shaft rotation speed change rate is calculated from a difference in synchronous rotation speed between a shift stage before a current gear shift and the second target intermediate shift stage as a target shift stage of a gear shift which is executed after the current gear shift. Accordingly, it is possible to avoid a situation in which a shifting time in the gear shift control of the step before the second target intermediate shift stage becomes very short and thus packing of a clutch pack is not executed in a timely manner.

摘要： Methods and systems are provided for performing a multiple gear downshift of a transmission gear by transiently operating in an intermediate gear. In response to ambient humidity and a condensate level in a charge air cooler, the transmission gear may be downshifted from a higher gear to an intermediate gear, and then to a requested lower gear. Downshifting through an intermediate gear may also be controlled based on the gear shift request.

The dual-clutch transmission comprises a first friction clutch and a second friction clutch together with a first transmission unit and a second transmission unit, in order to establish a first power transmission branch and a second power transmission branch. The dual-clutch transmission comprising a clutch actuator device for actuating the friction clutches and a gearshift actuator device for engaging and disengaging gears of the dual-clutch transmission. The method assuming that the motor vehicle is being driven in a high original gear and comprising the following steps: derivation of a first shift signal from an actuation of a control element by the driver; calculation of a target gear, which is lower than the original gear and which corresponds to the first shift signal; selection of an intermediate gear between the original gear and the target gear, opening of the friction clutch corresponding to the original gear and closing of the friction clutch corresponding to the intermediate gear, in order to transmit drive power via the power transmission branch corresponding to the intermediate gear; and engagement of the target gear, opening of the friction clutch corresponding to the intermediate gear and closing of the friction clutch corresponding to the target gear in the event that a second shift signal is derived from an actuation of a control element by the driver.

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.
