Title
(EN) TEST BENCH FOR A MOTOR VEHICLE HYBRID POWERTRAIN
(FR) BANC D'ESSAI POUR UN GROUPE MOTOPROPULSEUR HYBRIDE DE VEHICULE AUTOMOBILE
Abstract
(EN)
The present invention relates to a test bench for a hybrid powertrain making it possible to reduce the costs of operation and calibration of the pollution control functions. According to the invention, the test bench comprises only the first driving machine (10) of said first and second driving machines and control means comprising a determination means (15) for determining a first torque setpoint (CS1) of the first driving machine (10) equipping the test bench, said first setpoint (CS1) being calculated as a function of a second virtual torque setpoint (CS2) of the second driving machine and as a function of a third virtual torque setpoint (CS3) of the first driving machine (10), said third setpoint (CS3) being calculated for a model of the vehicle comprising a powertrain devoid of the second driving machine for executing said driving cycle. The invention also relates to a method for controlling the test bench.

La présente invention a pour objet un banc d'essai pour un groupe motopropulseur hybride permettant de réduire les coûts d'exploitation et de calibration des fonctions de dépollution. Selon l'invention, le banc d'essai comporte uniquement la première machine motrice (10) desdites première et deuxième machines motrices et des moyens de pilotage comportant un moyen de détermination (15) d'une première consigne de couple (CS1) de la première machine motrice (10) équipant le banc d'essai, ladite première consigne (CS1) étant calculée en fonction d'une deuxième consigne de couple virtuelle (CS2) de la deuxième machine motrice et d'une troisième consigne de couple virtuelle (CS3) de la première machine motrice (10), ladite troisième consigne (CS3) étant calculée pour un modèle du véhicule comportant un groupe motopropulseur démuni de la deuxième machine motrice pour l'exécution dudit cycle de conduite. L'invention concerne également un procédé de pilotage du banc d'essai.
