When an operating point that is determined by the engine speed (Ne), the engine torque (Te), and the vehicle speed falls within the zones of both a first vibration risk region (±1) and a second vibration risk region (±2), the dwell time (”T1) thereof is measured, and once this dwell time (”T1) reaches a predetermined vibration assessment time (”T1_Lim), the gear ratio of the continuously variable transmission is corrected towards the large side (low side) so that the operating point is moved out of the vibration risk regions (±1, ±2). |
