Abstract
Method for controlling the power plant of a motor vehicle with partial exhaust gas recirculation in which the fresh air flow rate and the partially recirculated gases flow rate are regulated either on a rich mixture control structure or on a lean mixture control structure and in which the flow rates are set, on the rich mixture control structure, to the setpoint values equal to the flow rate setpoint values of the lean mixture control structure during a transition from a rich mixture control structure to a lean mixture control structure.
