  "textContent": "The invention relates to a method to control the regeneration of an exhaust filter by raising the temperature of the exhaust gas above a given threshold. The regeneration may especially consist in burning the load of a diesel particulate filter. It is executed each time certain conditions are met, e.g. a certain amount of load has accumulated in the filter. According to the invention, the normal initiation of such a regeneration is advanced if the temperature of the exhaust gas is relatively high, and delayed if the temperature of the exhaust gas is relatively low. Thus fuel economy is increased due to the exploitation of already favourable conditions and the avoidance of unfavourable conditions for a regeneration.",
