Abstract

The gearbox includes a continuous transmission-ratio variator and a control and operating unit for causing, through actuator devices, the variation of the transmission ratio by the variator in dependence on signals supplied by sensors of the speed of the motor vehicle and the number of revolutions of the engine. In addition, a control device operable manually by the driver, for example a potentiometer with a sliding contact, is connected to the control and operating unit to supply to the unit an electrical signal variable in dependence on the extent of its operation. The control and operating unit is arranged to modify in a predetermined manner the mode of variation of the transmission ratio by the variator, in dependence on the signals supplied by the control device.
