ABSTRACT:
In the regulation of a motor-drive unit for a motor vehicle having a heat-engine and a continuously variable ratio transmission, in a clutch-engaged phase the heat-engine fuel feed is controlled so that it is a function of the displacement of the accelerator pedal of the vehicle and of the speed of the heat-engine such that the power delivered by the engine is substantially equal to the power required for that displacement of the accelerator pedal. In addition, the transmission ratio is controlled so that the speed of the heat-engine approaches an ideal speed which depends upon the power required and is predetermined for operation of the motor-drive unit which is optimalized in accordance with a chosen criterion. Operation is thus obtained with, for example, minimum consumption or pollution while taking into account, in the transient phase, the operation desired by the driver.
