DEVICE FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE WITH CONTROLLED IGNITION AND DIRECT INJECTION

摘要

The invention concerns a device for controlling an internal combustion engine (41) with direct injection and controlled ignition, adapted for avoiding sudden torque vibrations when switching from a homogeneous mixture to a stratified mixture combustion mode and inversely, comprising: means for determining (0) an input reference value (TQE-SP) of a transmission torque based on the position (PV) of an accelerator pedal (11).; means for computing (2) the value of at least a control of at least one means (40, 401, 402, 403) for adjusting the engine on the basis of the transmission torque reference value, said means comprising: a first reciprocal model (21) of the engine in its homogenous mixture combustion mode; a second reciprocal model (22) of the engine in its stratified combustion mode; correcting means (5) adapted for correcting the transmission torque reference value according to the combustion mode of the engine by a torque control (TQE-COR) extracted from a correction table (51) based on at least one variable representing the engine charge.
