<p>PROBLEM TO BE SOLVED: To prevent deterioration of an actuator and a speed-change gear by an axle vibration, since the service life of the actuator or the speed-change gear is affected with an automatic transmission, using an engagement clutch has proper torque transmission efficiency, axle vibration is generated on an input/output (I/O) axle of a speed-change gear in the relation between an engine torque and a running load and vehicle also vibrates thereby, and such vibrations occur, when an engine especially torque changes suddenly, which gives a driver feeling of incongruity. SOLUTION: In the control unit for vehicle that controls an assistant clutch, when changing gears to other gear ratios from a certain gear ratio, the torque transmit ratio by a start clutch is changed, so that when the amount of variations in the predetermined time of the generated torque by the torque generating means exceed a predetermined value.</p> |
