The regulator has an embarked controller calculating an instantaneous speed (Vinst), where the regulator varies the instantaneous speed at an interval defined by a minimal speed (Vmin) and a maximum speed (Vmax) based on an instantaneous consumption (COinst) and a maximum consumption (COmax) to limit fuel consumption. The instantaneous speed increases up to the maximum speed when the instantaneous consumption is less than or equal to the maximum consumption or decreases up to the minimum speed when the instantaneous consumption is higher than the maximum consumption at the interval. Le but de ce régulateur est de faire varier la vitesse d'un véhicule en fonction du relief sur lequel il évolue afin de diminuer la consommation de carburant. Le régulateur de vitesse est un devenu un système de confort de conduite très répandu sur les véhicules. Néanmoins, il permet uniquement de maintenir une vitesse instantanée V égale à une vitesse maximale V et non pas de faire varier V entre un intervalle limité par une vitesse minimale V et une vitesse maximale V , le tout en fonction d'une consommation de carburant.
