Abstract

Process for calculating the torque of an internal combustion engine having electronic injection. The method includes having a cogged target with an indexed reference rotating before a fixed sensor. The defects of the target are corrected by distinguishing the combustion interval of the target from the reference. A term assigned to each interval is $g(b)i which is determined in the absence of combustion from the measurement of the engine torque which is proportional to the pressure in the commutator represented by the equation Ci=K.Pcoll=&agr;(&Sgr;N+$g(b)i)N2 where Ci is the engine torque, Pcoll is the pressure, N is the engine power, K is the proportionality factor and &agr; is a constant term.
