  • Publication number: 20190096146
    Abstract: A transmission control device detects deterioration of a clutch that can adjust a connection or disconnection state between an engine output shaft and a first input shaft by a pressure of a hydraulic fluid supplied to a first hydraulic chamber. The transmission control device includes a supply control unit that supplies the hydraulic fluid such that the first hydraulic chamber has a predetermined pressure in a state of keeping rotational speed of the engine output shaft constant, a clocking processing unit that measures elapsed time since the supply control unit starts a supply of the hydraulic fluid to the first hydraulic chamber until a rotational speed of the first input shaft exceeds a predetermined rotational speed and determines whether the elapsed time exceeds a predetermined allowed time, and a deterioration determination unit that determines that the first clutch deteriorates in a case where the time elapsed exceeds the allowed time.

  • Patent number: 10174796
    Abstract: A clutch-side transmission circuit transmits, from a clutch pedal, a restoring action of the depressed clutch pedal. A switching device connects a first clutch-side hydraulic circuit to the pedal-side hydraulic circuit when a shift lever SL is tilted forwards and connects a second clutch-side hydraulic circuit to the pedal-side hydraulic circuit when the shift lever SL is tilted rearwards. A first clutch is engaged in response to the restoring action of the clutch pedal being transmitted from the first clutch-side transmission circuit. A second clutch is engaged in response to the restoring action of the clutch pedal being transmitted from the second clutch-side transmission circuit.

  • Patent number: 9556934
    Abstract: 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 smaller than that of the start gear by one speed or higher.

A first input shaft is connected to a first clutch and a second input shaft is 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. Two of the gears are set as a start gear and a support gear, respectively. A one-way clutch is provided between the support gear and the first input shaft to let the support gear freewheel when a vehicle is started by synchronously engaging the start gear and the support gear to the second input shaft and the first input shaft, respectively, and simultaneously bringing each of the first clutch and the second clutch into a connected state. A third clutch connects the first input shaft and the second input shaft and rotates them together when the vehicle is started.
