<p><P>PROBLEM TO BE SOLVED: To improve drivability by reducing speed change shock. <P>SOLUTION: This transmission 20 includes a gear ratio change mechanism 20a, a driving circuit 8 as a motor driving section, and an ECU 7 as a control section. The gear ratio change mechanism 20a has a motor 30 for continuously varying the change gear ratio. The driving circuit 8 applies a pulse voltage to the motor 30. The ECU 7 outputs a control signal to the driving circuit 8. At least one of the duty ratio and the pulse height of the pulse voltage is changed according to the control signal. The ECU 7 performs a low-pass filtering process on the control signal, and thereafter outputs the low-pass filtered control signal to the driving circuit 8. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
