Hybrid powertrain controlling system for e.g. four-door sedan, has calculating unit determining setpoints for heat and electric engine units, starter-alternator and clutch, from battery charge state of battery, speed and torque request

摘要

#CMT# #/CMT# The system has a powertrain (2) including a heat engine unit (2a) and an electric engine unit (2e). A calculating unit (8) determines operating setpoints for the heat engine unit, electric engine unit, starter-alternator (2b) and clutch (2c) from a charge state of a battery (5), speed of a motor vehicle and total torque request from a driver during starting phases. An interface (6) between the driver and vehicle is connected to the calculating unit and transmits information to the calculating unit on the request of the driver. #CMT# : #/CMT# An independent claim is also included for a method for controlling a hybrid powertrain unit. #CMT#USE : #/CMT# System for controlling a hybrid powertrain of a hybrid vehicle e.g. motor vehicle (claimed) such as four-door sedan and mini cooper. #CMT#ADVANTAGE : #/CMT# The configuration of the system optimizes operation of the powertrain in transient starting phases in order to minimize energy consumption, while ensuring driveability. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of main elements constituting a hybrid powertrain controlling system. 2 : Powertrain 2a : Heat engine unit 2b : Starter-alternator 2c : Clutch 2e : Electric engine unit 5 : Battery 6 : Interface 8 : Calculating unit.
