Übersetzungssteuerung für ein kontinuierlich variables Getriebe.

摘要

A control system for a continuously variable transmission for a motor vehicle has a transmission ratio control valve (TR) for controlling the transmission ratio. The transmission ratio is controlled in accordance with a transmission ratio changing speed (di/dt). During acceleration from a vehicle speed in a low speed range, the transmission ratio changing speed (di/dt) is set to a large value so as to quickly downshift the transmission ratio.
