Abstract
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 (α) and a second vibration risk region (α), the dwell time (ΔT) thereof is measured, and once this dwell time (ΔT) reaches a predetermined vibration assessment time (ΔT_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 (α).
