<p>The device allows to regulate both the engine (15) and the transmission (14) - by steps or not - of a motor vehicle so as to reduce as much as possible the fuel consumption thereof. For this purpose, the desired power of the engine being transmitted through the foot-pedal (10) of the vehicle, the appropriate gear, in other terms the transmission ratio is adjusted through the characteristic field (12) of the transmission. The engine (15) will thus be adjusted in relation to the number of revolutions given by the modification of the transmission ratio, said number of revolutions, being related to the characteristic field (13) of the engine or to the characteristic curve of the characteristic field (13) of the engine, corresponds to the minimum fuel consumption. The device is provided, preferably, so that in normal operation conditions, it is adjusted for optimal consumption, namely in relation to the characteristic field (13) of the engine. For passing from optimal consumption running to optimal power running, elements (91) are provided which take into account the functional behaviour of the motor vehicle in corresponding situations. </p> |
