<p>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.</p> |
