    摘要： A method of controlling a dual clutch transmission, a dual clutch transmission, and a vehicle equipped with the same which can reduce the load on a clutch on a start gear side to reduce the wear thereof and therefore make the clutch replacement interval longer. There are a first input shaft to be connected to a first clutch and a second input shaft to be connected to a second clutch. A set of odd-numbered gears and a set of even-numbered gears are arranged respectively across the first input shaft and second input shaft and an output shaft. When a vehicle starts, a start gear and a support gear are synchronously engaged to the second input shaft and the first input shaft, respectively, and simultaneously connecting the first clutch and the second clutch partially (half clutch state) to the first input shaft and the second input shaft, respectively, the support gear having a gear ratio larger than that of the start gear by one speed or higher.

    摘要： In a gear shift control apparatus for a vehicle, since a torque sharing rate is set as a constraint for a motion equation for an automatic transmission, suitable control in torque delivery, which is considered difficult in gear shift control, can be implemented and also the motion equation can be solved. Furthermore, when at least four control operation amounts must be determined in order to achieve two gear shift target values, another engaging device is classified into any of an engaging-side clutch and a releasing-side clutch depending on how another clutch torque acts on progress of a gear shift, hence in addition to achieving torque sharing in accordance with a torque sharing rate between the engaging-side clutch and the releasing-side clutch, torque sharing among a plurality of engaging devices classified into a same side can be arbitrarily set. As a result, the respective control operation amounts can be determined.

    摘要： Control apparatus for hybrid vehicles are described which reduce the heat generated by a clutch and improve the response of the hybrid vehicle when an operator requests a high degree of acceleration while starting the engine and the transmission is required to perform a shift-down. In one embodiment, when the engine is required to start while the transmission is required to perform a shift-down action, the control apparatus holds a hydraulic pressure of a releasing side clutch of the transmission at a predetermined lowest stand-by value preventing a slipping action of the releasing side clutch, while a clutch K0 between the motor and engine is placed in a slipping state, and reduces the hydraulic pressure of the releasing side clutch from the lowest stand-by value in the slipping state of the clutch K0 after the clutch K0 is placed in the fully engaged state.

    摘要： A method of managing clutch thermal loads in a multi-speed dual-clutch transmission (DCT) that is paired with an internal combustion engine in a vehicle is provided. The method includes assessing operation of the DCT and ascertaining a mode of operation of a clutch in the DCT. The method also includes predicting, in response to the ascertained mode of operation of the clutch, an amount of time remaining until the clutch reaches a threshold temperature. The method additionally includes ascertaining whether the predicted amount of time remaining until the clutch reaches the threshold temperature is within a predetermined range of time. Furthermore, the method includes activating an indicator configured to signal that the predicted amount of time remaining is within the predetermined range of time. A vehicle having a DCT, an internal combustion engine, and a controller configured to predict thermal loading on a clutch in the DCT is also disclosed.
