Method for controlling motorization system of vehicle, involves controlling operating conditions of trap by applying specific law to recommendation unit to recommend transmission ratio change when trap is maintained in destocking stage

摘要

The method involves controlling operating conditions of a nitrogen oxide trap by applying specific law to a recommendation unit (5) so as to recommend possible change of transmission ratio when the trap is activated or maintained in a destocking stage. A list of possible operating points of the motorization system is established if any action is taken place on the transmission ratio. Distance between a reference point and each operation point of the list is calculated. A preferred operating point for which the distance is minimal is retained. An independent claim is also included for a motorization system for a vehicle.
