ABSTRACT:
Method and device for controlling a motor vehicle power unit consisting of an internal combustion engine and a variable-ratio power divider transmission. For adjusting the output, use is made of the data from the only sensor sensing the speed at the transmission output end, and from the accelerator and brake pedals. The resultant reference value is directly transferred to an engine function generator in which engine characteristics are stored. The output signal from the engine function generator is used to control the throttle or the fuel supply system actuating lever. The reference generator also directly influences a speed function generator, in which the optimum speed is stored. Its output signal is linked with the indication from the sensor so as to form a reference value for the transmission ratio and is processed in a transmission control unit for form actuating signals for the transmission.
