Abstract
A vehicle control system is provided to prevent an occurrence of an engine misfire which may be caused by an execution of ignition retard during lean-burn operation of an engine. The vehicle control system is configured to determine a starting point of an inertia phase when a shifting operation is demanded in the lean-burn mode. The vehicle control system is further configured to switch from the lean-burn mode to the stoichiometric mode before the starting point of the inertia phase, and to execute an ignition retard of the engine in the stoichiometric mode.
