SYSTEME DE COMMANDE EN COUPLE D'UNE MOTORISATION HYBRIDE PARALLELE

摘要

The invention concerns a torque control system for a motor vehicle parallel hybrid engine transmission unit, characterised in that the system comprises: means (8) for determining the running condition of the vehicle; means (6) for managing the operating modes of the hybrid engine-transmission unit adapted to receive in input part of the data, boolean or not, derived from the means (8) determining the running condition of the vehicle; means (12) for boosting the dynamic performances of the vehicle adapted to receive in input the other part of the data, boolean or not, derived from the means (8) determining the running condition of the vehicle; means (7) for managing the electric power available for the vehicle; means (9) for determining the running condition of the engine-transmission unit; means (10) for continuously determining the total engine torque (Cm) to be supplied to the vehicle wheels adapted to receive in input data, boolean or not, derived from the managing and booster means (6, 7, 12) and those derived from the means (9) determining the running condition of the engine-transmission unit, by giving priority to those derived from the managing and booster means (6, 7, 12), so as to respectively control the torque (Ce) of the electric engine (1) and the torque (Ct) of the heat engine (2) according to the desired (Ce)/(Ct) ratio.
