Title:
CONTROL CIRCUIT AND METHOD FOR PRODUCING A CONTROL SIGNAL FOR CONTROLLING A CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO2003060352
Kind Code:
A3
Abstract:
The invention relates to a control circuit for producing a control signal (I) for controlling the adjustment of a continuously variable transmission ratio of a continuously variable transmission, having an input side (7), an output side (8) and a primary valve (15) which is controlled by the control signal (I) and is used to adjust the transmission ratio. Said control circuit comprises means for producing the control signal (I) according to the operating parameters of the vehicle which are transmitted to the control circuit. According to the invention, the control signal (I) is produced according to a value y for a desired speed of the transmission ratio variation or a variable derived therefrom. The value y for the desired speed of the transmission ratio variation is determined on the basis of the operating parameters transmitted to the control circuit.
