Abstract
According to the invention, a) from the position of an accelerator pedal actuated by the driver, a value is extracted of a power (P.sub.d) requested by this driver, b) in various vehicle operating phases, a base power (P.sub.b) absorbed by the vehicle over and above the power possibly required to move the latter is calculated, and c) the quantities of air and of fuel admitted into the engine are controlled in such a way as to drive the power (P.sub.m) which it delivers to the sum of the requested (P.sub.d) and base (P.sub.b) powers.
