ABSTRACT:
A method for regulating a belt variator type transmission unit for motor vehicles, and which includes a belt variator, a reversing unit and a hydraulically controlled engine drive coupling that controls the reversing unit to provide forward and reverse drive connection between the engine and variator. The drive coupling comprises a forward coupling and a reverse coupling including fluid driven clutches which may be operated via a pressure regulating unit that provides an adjustable clutch actuating pressure. The clutch actuating pressure is hydraulically regulated both as a function of engine Pitot pressure which is representative of the engine speed, and as a function of a regulated pressure which is set by an electronically controlled valve.
