A method for working out instruction cartography for a temperature at entry into a filter. The method determines for each combination, which includes a soot mass in a particle filter, a temperature at the filter output, an air flowrate through the filter and a soot combustion rate in the filter and is associated with a time t, a value assignable to the instruction, wherein the value is selected such that the filter output temperature remains less than a maximum permissible temperature after a pedal release at a time L.

The inventive system for estimating quantities of pollution compounds emitted in the exhaust gas of a diesel engine for a motor vehicle comprises means for regenerating a solid particle filter and an electronic control unit which manages the engine operation and is provided with one or several data memories. Said system also comprises one or several neurone networks () and networks () of input data representative for the engine operation and possibly for the vehicle motion, said data is available in the electronic control unit for managing the engine operation without an additional sensor. Said system also comprises means () for cumulating estimated quantities.

A method of controlling elements used to execute the elementary functions of internal combustion engines. The method controls the elements using measurement signals provided by sensors, determines theoretical signals that have to be provided by reference sensors at a current operating point of the engine, determines deviations between the theoretical signals and the signals measured by the reference sensors, and establishes signal correction instructions for the elements according to the determined deviations.

A method for controlling an internal combustion engine for regenerating an exhaust gas purifying mechanism arranged on an exhaust line of the engine during a phase of regeneration of the purifying mechanism. The method analyzes an exhaust gas composition solely downstream of the purifying mechanism and develops, based on the analysis, a control signal for the engine to modify an exhaust gas composition upstream of the purifying mechanism.

The invention concerns a method for controlling the operating conditions of a probe () associated with means purifying () exhaust gases of an internal combustion engine (), which consists in comparing an output signal of the probe with a reference value, and in acting on the probe () to decrease a difference between the output signal (S) and the reference value.
