Abstract
A device for controlling a controlled-ignition direct-injection internal combustion engine to avoid abrupt variations in torque when switching from homogeneous-charge to stratified-charge combustion mode and vice versa, includes a determinator for determining a reference value of a transmission torque as a function of a position of an accelerator pedal. A calculator is provided for calculating a value of at least one command of at least one controller for controlling the engine based on a datum value for a transmission torque. A corrector is configured to correct the datum value of the transmission torque as a function of the engine combustion mode by applying a torque correction taken from a correction table as a function of at least one variable representing a load on the engine. The calculator has a first inverse model of the engine in its homogeneous-charge combustion mode and a second inverse model of the engine in its stratified-charge combustion mode.
