Method for controlling operation of engine e.g. direct injection compression ignition engine, of motor vehicle, involves determining stability of torque of modeled engine, and modifying parameters of filter when torque is unstable
The method involves determining information relative to speed of an engine (12). Information relative to a fuel loop (14) is determined from the information relative to the engine speed. Torque of the engine is modeled from the information relative to the loop. Stability of the torque of the modeled engine is determined. Parameters of a filter i.e. low-pass filter, are modified when the torque is unstable. A pump (20) is activated according to a signal of a sensor (24), where response time of the pump with respect to the detection of sensor is taken into account in modeling the torque. An independent claim is also included for a vehicle comprising an engine.
