<P>PROBLEM TO BE SOLVED: To suppress shock that might occur in a gear mechanism irrespective of whether or not an engine is being operated. <P>SOLUTION: When the engine is stopped, and an absolute value of previous execution torque T* is a threshold Tref1 or less (when it is within a gradual change zone), the execution torque T* is gradually changed (S120, S130, S160, S180). When the engine is operated, and the absolute value of the previous torque T* is a threshold Tref2 or less that is larger than the threshold Tref1 (when it is within the gradual change zone), the execution torque T* is gradually changed (S120, S140, S170, S180). By this, even when there is a difference between the previous torque (previous T*) and torque outputted to an axle side, change of an abutting portion of gears is carried out in a state of gradually changing the execution torque T*, and the shock that might occur in the gear mechanism can be suppressed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
