    摘要： A dual clutch transmission comprises a first clutch (C1) to be engaged for setting any one of forward-traveling odd-numbered speeds and a second clutch (C2) to be engaged for setting any one of forward-traveling even-numbered speeds. The dual clutch transmission establishes a desired forward-traveling speed by alternately engaging/disengaging the first and second clutches (C1,C2). A backward-traveling drive train is adapted to be driven by engaging one of the first and second clutches. When a reverse mode is established by a mode setting means, the one of the first and second clutches (C1) is engaged to drive the backward-traveling drive train (78,75,14a) by setting a speed change manipulator (95) at a backward-traveling position, and the other of the first and second clutches (C2) is engaged to drive a fixed one forward-traveling speed drive (73,77) train by setting the speed change manipulator at a forward-traveling position. While the reverse mode is established, the backward-traveling drive train (78,75,14a) and the fixed one forward-traveling speed drive train are kept activated regardless of whether the first or second clutch is engaged.

    摘要： An automatic transmission includes a planetary gear arrangement, and a plurality of engaging elements each arranged to vary an engagement state among the rotating elements of the planetary gear arrangement in such a manner to establish a normal gear ratio set and an emergency gear ratio set excluded from the normal gear ratio set. A control section of the automatic transmission performs the following: selecting a gear from the normal gear ratio set in accordance with a running state of a vehicle under normal operating conditions; controlling the engagement state of each of the engaging elements in such a manner to shift into the selected gear; detecting a failure in the engaging elements; selecting an escape gear ratio set from the normal gear ratio set and the emergency gear ratio set; and driving the vehicle with the escape gear ratio set when a failure is detected in the engaging elements.
