<p>A 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 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 to output the low-pass filtered control signal to the driving circuit (8).</p> |
