<p>PROBLEM TO BE SOLVED: To prevent a speed changing time from increasing and a gear shift operation from being disabled by increasing the rising rate of speed of an engine when the rising rate of rotation of the engine is low in double clutch control. SOLUTION: When a main gear having no mechanical synchronous mechanism is shifted, a specified synchronous control is performed and, when a transmission is shifted down, a specified double clutch control is performed. After the double clutch control disengages a clutch and gears, an engine speed is increased to specified target speed to engage the clutch a dog gear speed on a target main gear stage is increased to near a sleeve speed and, if the engine speed does not reach the target engine speed even after a specified time is elapsed from the start of the double clutch control a control to increase the target engine speed is performed.</p> |
