Patent number: 9254760Abstract: A hybrid electric automotive powertrain includes an electric machine operable in propulsive and regenerative modes. The machine has positive and negative torque limits for the propulsive and regenerative modes, respectively, to reduce potential thermal damage to the machine due to overheating. The negative and positive torque limits are reduced independently as a temperature of the machine increases. The negative torque limit may be reduced at a greater rate than the positive torque limit.Type: GrantFiled: March 27, 2014Date of Patent: February 9, 2016Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Shunsuke Okubo, Carol L. Okubo, Walter J. Ortmann, Marvin P. Kraska

Patent number: 9163578Abstract: Disclosed are a control device and a control method that are used with an internal combustion engine in which the air-fuel ratio in the vicinity of an ignition plug differs from the overall air-fuel ratio in a cylinder, and capable of properly fulfilling demands concerning various capabilities of the internal combustion engine by accurately reflecting each of the demands in the operation of each actuator. Three physical quantities, namely, a torque, an efficiency, and an air-fuel ratio, are used as controlled variables for the internal combustion engine. Target values for the controlled variables are then set by integrating at least some of demands concerning a capability of the internal combustion engine into the three physical quantities.Type: GrantFiled: October 15, 2008Date of Patent: October 20, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koichi Ueda, Kota Sata, Shinichi Soejima, Kaoru Ohtsuka

Patent number: 9140179Abstract: A method includes combusting air within a plurality of cylinders of an internal combustion engine by injecting a fuel into the plurality of cylinders. The method further includes expanding a first portion of an exhaust gas generated from the plurality of combustion cylinders via a turbine. The method further includes controlling at least one of feeding a second portion of the exhaust gas via an exhaust channel bypassing the turbine; and recirculating a third portion of the exhaust gas to the plurality of combustion cylinders via a recirculation channel, as a function of an intake manifold air temperature and pressure at which the engine is operated.Type: GrantFiled: October 19, 2012Date of Patent: September 22, 2015Assignee: General Electric CompanyInventors: Roy James Primus, Omowoleola Chukwuemeka Akinyemi, Thomas Michael Lavertu, James Robert Mischler, Venu Gopal Gummadavelli

Patent number: 9133781Abstract: A vehicle integrated control device that can request torque having an appropriate magnitude and change speed to be given to an engine control unit from a drive system manager. A first maximum torque and a second maximum torque are presented to a drive system manager from an engine control unit. The drive system manager refers to the first maximum torque and the second maximum torque which are presented, and determines a request torque to be given to the engine control unit. The first maximum torque is a maximum torque that can be realized when only an operation amount of a throttle is actively changed without actively changing an operation amount of a wastegate valve. The second maximum torque is a maximum torque that can be realized when both the operation amount of the throttle and the operation amount of the wastegate valve are actively changed.Type: GrantFiled: June 28, 2012Date of Patent: September 15, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Satoshi Yoshizaki, Shinichi Soejima, Satoru Tanaka, Kiyonori Takahashi

Patent number: 9086025Abstract: Systems and methods for correcting mass airflow sensor drift include an operation conditions module to interpret a base calibration function, a MAF sensor input value, and a current operating condition. A MAF correction module determines an expected MAF value in response to the current operating condition and a predetermined operating condition. The MAF correction module will also determine an adjusted MAF value in response to the expected MAF value, the base calibration function, and the MAF sensor input value. A MAF reporting module is structured to provide the adjusted MAF value.Type: GrantFiled: October 8, 2012Date of Patent: July 21, 2015Assignee: Cummins Inc.Inventors: Ashwin Vyas, Vivek A.

Patent number: 9062616Abstract: A method of controlling torque load of multiple engines according to a torque distribution algorithm includes determining a combined torque output value responsive to actual torque outputs of first and second engines. A desired torque output for the first engine is determined responsive to a first desired contribution portion of the combined torque output value, and a desired torque output for the second engine is determined responsive to a second desired contribution portion of the combined torque output value. A torque error for each of the first and second engines is determined responsive to a difference between the desired torque output for a respective one of the first and second engines and the actual torque output from the respective engine. Operation of each of the first and second engines is controlled responsive to the respective torque error.Type: GrantFiled: August 15, 2012Date of Patent: June 23, 2015Assignee: Caterpillar Inc.Inventors: Yanchai Zhang, Evan Earl Jacobson
