发明名称 CONTROL DEVICE FOR VEHICULAR CONTINUOUSLY VARIABLE TRANSMISSION
摘要 Properly changing a gear ratio to a lower vehicle speed side during vehicle deceleration to properly ensure starting performance at the next vehicle start. When a forward/reverse switching device 16 is in a power transmission interrupted state during vehicle deceleration running, a gear ratio ³ of a continuously variable transmission 18 is changed earlier to the lower vehicle speed side as compared to when the forward/reverse switching device 16 is in a power transmittable state and, therefore, the gear ratio ³ can properly be changed to the lower vehicle speed side during vehicle deceleration regardless of individual variation etc., even in shift control of the continuously variable transmission 18 only through FF control. Thus, the gear ratio ³ is more easily returned to a maximum gear ratio ³max before a vehicle stop, and the starting performance can properly be ensured at the next vehicle stop.
