摘要

#CMT# #/CMT# The system has a total torque set point determining unit (10) determining a total torque set point from requirements of a driver. An information receiving unit (11) receives information for controlling a gear box (3) by considering constraints of drivability. An acceptable working point determining unit (12) and a working point optimizing unit (13) determine a speed ratio of the gear box and working state and torque of a heat engine (2) and an electrical engine (4) corresponding to a request of the driver according to conditions of the drivability. #CMT# : #/CMT# An independent claim is also included for a method for controlling hybrid propulsion of a motor vehicle. #CMT#USE : #/CMT# System for controlling a hybrid propulsion of a power train of a motor vehicle i.e. hybrid vehicle. #CMT#ADVANTAGE : #/CMT# The configuration of the system reduces the fuel consumption and the different constraints of drivability. The configuration of the system permits to control the hybrid propulsion in an efficient manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block representation illustrating main elements of a hybrid propulsion controlling system. 2 : Heat engine 3 : Gear box 4 : Electrical engine 10 : Total torque set point determining unit 11 : Information receiving unit 12 : Acceptable working point determining unit 13 : Working point optimizing unit.
