Patent number: 6953023Abstract: A method for controlling a multi-cylinder internal combustion engine having electronically controlled airflow comprising limiting a currently available maximum engine torque below maximum torque based on a limited torque output condition, the limited torque output condition not being based on current ambient temperature or pressure conditions. The method also includes determining a driver demanded torque based on a current throttle position. The method further includes controlling the engine to deliver the driver demand torque if the internal engine condition does not indicate the limited torque output condition or to deliver a calibratable percentage of the currently available maximum torque if the internal engine condition indicates a limited torque output condition.Type: GrantFiled: September 5, 2003Date of Patent: October 11, 2005Assignee: Ford Global Technologies, LLCInventors: Per Persson, Bengt Norén, Gregory P. Brown

Patent number: 6915198Abstract: Rapidly changing torque demand is coordinated in an automotive vehicle having an engine and at least one motor. An engine base torque level indicating slowly changing torque produced by the engine is received. A motor torque is determined as a difference between a fast desired torque and the engine base torque level. An engine fast torque is determined as a difference between the request for fast desired torque and the motor torque. The motor torque is determined as a motor torque request and the engine fast torque is determined as an engine torque request.Type: GrantFiled: September 11, 2003Date of Patent: July 5, 2005Assignee: Ford Global Technologies, LLCInventors: Anthony Mark Phillips, Diana Yanakiev, Bengt Norén, Jonas Jerrelind

Patent number: 6907337Abstract: Hybrid vehicles and other vehicles with one or more torque producing devices operate more effectively with proper resolution of torque requests. In one aspect of the present invention, a plurality of vehicle force and torque requests are resolved at different levels depending on the vehicle architecture. In another aspect of the present invention, torque requests are resolved into base requests and fast requests depending upon response times of torque devices satisfying these requests.Type: GrantFiled: September 11, 2003Date of Patent: June 14, 2005Assignee: Ford Global Technologies, LLCInventors: Anthony Mark Phillips, Johan Karl Henning Tollmen, Bengt Norén, David Karl Bidner, Fredrick Hansson, Diana Yanakiev

Patent number: 6877480Abstract: A method of controlling torque output of an engine including receiving an acceleration pedal position signal and receiving an engine speed signal. The method also includes calculating a modified engine speed signal as a function of the engine speed signal and the acceleration pedal position signal. The method further includes requesting engine output torque as a function of the acceleration pedal position signal and the modified engine speed signal.Type: GrantFiled: September 5, 2003Date of Patent: April 12, 2005Assignee: Ford Global Technologies, LLCInventors: Per Persson, Bengt Norén

Publication number: 20050060079Abstract: Torque demand is coordinated in a vehicle. Information defining at least one torque production limitation for a first torque producing device is received. A request for torque is compared with the first torque producing device torque production limitation. If the comparison does not result in the request for torque exceeding a limitation, a first coordinated torque request is determined as the request for torque and a null torque is determined as a second coordinated torque request. Otherwise, a first excess requested torque is determined as the difference between the request for torque and the exceeded limitation, the first coordinated torque request is determined as the exceeded limitation, and the second coordinated torque request is determined as the first excess requested torque.Type: ApplicationFiled: September 11, 2003Publication date: March 17, 2005Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Anthony Phillips, Diana Yanakiev, Bengt Noren, Jonas Jerrelind

Patent number: 6609364Abstract: A method for controlling a direct injection combustion engine is disclosed. The method includes generating an air/fuel mixture to the respective cylinders of the engine, and switching between at least a first mode of operation and a second mode of operation of the engine by adjusting the air/fuel mixture supplied to the engine and the amount of time for injecting the mixture. The switch in mode of operation is initiated in connection with operation of the engine with an air/fuel mixture adjusted in such manner that correct operation of the engine is allowed in both modes of operation during the switch. An arrangement for such a control is also disclosed. The method and arrangement provides an improved control between, for example, a stratified and a homogeneous mode of operation in a direct injection engine, wherein stable combustion in the engine and improved comfort for the passengers is achieved.Type: GrantFiled: December 20, 2001Date of Patent: August 26, 2003Assignee: Volvo Personvagner ABInventors: Martin Litorell, Johan Lindström, Bengt Norén
