<P>PROBLEM TO BE SOLVED: To control running quality of a vehicle without requiring a new actuator. <P>SOLUTION: The vehicle 1 includes: front wheels 14 and 14 to which torque from an engine 10 is directly transmitted; and rear wheels 18 and 18 to which the torque from the engine 10 is transmitted through a coupling device 30. An actuator 31 varies a condition of the coupling device 30, and thereby a torque distribution of the front and rear wheels is changed. In the vehicle 1, a frequency of a PWM control output which is output to the actuator 31 of the coupling device 30 is changed to a lower frequency side than the frequency of the PWM control output when a change control of the torque distribution by the coupling device 30 is carried out, thereby applying vibration along a rotation direction of the rear wheels to the rear wheels 18 and 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
