<p>The invention relates to a method for controlling an internal combustion vehicle engine, in which the flow rate of gas (Qengine) entering the engine (Qengine) is estimated using the following formulation: Q engin e V cyl /2*N/60*? i ntake * ? intak e (N,? intake) *? exhaust (N,? exhaust )* n ? i=1 f i (a i) (1), in which Vcyl is the engine cylinder capacity, N is the engine speed, ?intake is the density of the gases entering the engine, ?intakeis the intake performance of the gases entering the engine, ?exhaust is the density of the exhaust gases, ?exhaust is the exhaust performance of the gases leaving the engine and n ? i=1 fi(ai) is a product of correction functions f(ai) dependent respectively on another parameter ai, wherein 1 = i = n.</p> |
