Motor vehicle internal combustion engine controlling method involves controlling turbochargers with actuating signals corrected by signal which is sum of correction value and regulating signal, to reduce difference of air flow

摘要

The method involves determining a supercharged pressure set point (Cp), and a difference of air flow traversing two turbochargers. An actuating signal (At) of the turbochargers is determined to obtain the set point in a manifold. The turbochargers are controlled with actuating signals (At1, At2) corrected by a correction signal which is a sum of a regulating signal (Cr) and a stored correction value, in order to reduce the difference. An independent claim is also included for a system of controlling a heat engine supercharged using two turbochargers.
