TRANSMISSION CONTROL APPARATUS FOR INFINITELY VARIABLE TRANSMISSION

A transmission control apparatus for an infinitely variable transmission in which a transmission operating amount is selected by a transmission operating amount selecting system from a memory stored table based on transmission control information from transmission control information detectors which detect the transmission control information such as a throttle opening position command signal, etc., and a driving motor which enables the transmission operation of the infinitely variable transmission to be controlled in an open-loop fashion by a transmission control system in accordance with the transmission operating amount. The transmission operating amount selected by the transmission operating amount selecting system is compared with a predetermined set value by a transmission operating amount decision system to decide whether or not the transmission operating amount is equal to or larger than the predetermined set value, and based on the decision result, the driving motor is driven to rotate by a driving speed selecting system such that, for example, at the time of usual transmission in which the operating amount is small, the driving motor is driven at a low speed, whereas at the time of rapid acceleration or kick down in which the operating amount is large, the driving motor is driven at a high speed.
