Embodiment Construction

[0012] Referring now to the drawings, in which the content shown herein is only for the purpose of describing certain exemplary embodiments and not for the purpose of limiting them, figure 1 A vehicle 100 is schematically depicted comprising a powertrain and control system including an engine 14; a dual-mode compound-split electromechanical transmission 10 including a first electric machine and a second electric machine (' MG-A') 56 and ('MG-B') 72; also include a plurality of control modules configured to implement the control schemes recited and described herein. The vehicle 100 includes a hood 102 through which the powertrain is accessible when opened. Opening and closing of the hood 102 is monitored by a hood switch 112 ('HS').

[0013] The exemplary engine 14 comprises a multi-cylinder internal combustion engine selectively operable in several states to transmit torque to the transmission 10 via the input shaft 12 and may be a spark-ignition engine or a compression-igni...

Abstract

A control method for vehicular hybrid powertrain system includes monitoring operator inputs to an accelerator pedal and a transmission gear selector, and determining an operator torque request based upon the operator inputs to the accelerator pedal and the transmission gear selector. Torque output from the electric machine is commanded based upon the operator torque request. Engine output is controlled based upon the operator torque request and the commanded torque output from the electric machine. Vehicle hood position is monitored and the engine output is controlled correlative to the operator input to the accelerator pedal when the monitored position of the vehicle hood is open and the operator input to the transmission gear selector is one of a PARK and a NEUTRAL position.

Description

[0001] This application requires the equity of the US temporary application No. 60 / 986,073 submitted on November 7, 2007, which is combined in this article by reference. Technical field [0002] This openness involves the control method and control system for hybrid power systems used for vehicles. Background technique [0003] The narrative in this section only provides background information related to this disclosure, and does not constitute existing technologies. [0004] The known power system includes a torque generated device, which includes the Internet Combustion Engines and Electric Machines, which transmits torque from the transmission device to the output part.The output partly connected to the drive system for motor vehicles.Exemplary power system includes dual-mode composite-diversified electromechanical transmission, which uses input components to receive torque from the original motor power source (preferably for internal combustion engines) and use output componen...
