Method of controlling the overload in an internal combustion engine and vehicles with an internal combustion engine overloaded with electronic control devices for controlling the overload

摘要

A vehicle having a combustion engine supercharged by a turbocharger ( 6 ) with variable turbine geometry and having electronic control members ( 3 ) controlling the supply of fuel and air to the combustion chamber of the engine. The control members are designed, during forward travel of the vehicle, on the basis of input information on at least road gradient and gas pedal position, to estimate future road resistance and the time period up to a future transient in the operating condition of the engine. The control members are designed to control changes in the turbine geometry during the time period so as to optimize the response of the engine when the transient arises.
