REQUIREMENTS FOR THE CORRECTURING OF THE TRANSITIONAL TRANSITION TIME INSTALLATION OF A FUEL-RAPPING MACHINE AND ITS USE FOR THE PURPOSE OF MOTOR CHANGE

摘要

According to the invention an entry into a transient state of the engine is detected and the ignition advance is then corrected as a function of the time derivative of the induction pressure (P), substantially until leaving the transient state. In a sampled system, the transient-state advance correction (TACi?) at the sampling instant (i) is obtained from expression (I) where Pi?, Pi-1? are samples of the induction pressure and k is a factor between 0 and 1. Application to the smoothing out of jerks when changing gears in a motor vehicle.
