In the control method, feedback control is performed so that an air-fuel ratio in the combustion chamber becomes a target value by controlling the fuel injection valve, using an air-fuel ratio measured value obtained by the air-fuel ratio sensor. In the feedback control, a transfer function is used, the transfer function being obtained by system identification of a plant having the air-fuel ratio in the combustion chamber serve as an input and the air-fuel ratio measured value obtained by the air-fuel ratio sensor serve as an output.Type: GrantFiled: April 26, 2019Date of Patent: July 18, 2023Assignee: NISSAN MOTOR CO., LTD.Inventor: Yousuke Sakayori

Patent number: 11703119Abstract: The control method for a constant speed running of a vehicle performs a vehicle speed control for downshifting the gear position of the automatic transmission when the acceleration/deceleration of the vehicle is larger than the determination value during the constant speed running control. In the control method, the automatic transmission includes a plurality of gear positions that can be downshifted during the constant speed running control, and among the plurality of gear positions, the determination value between the gear positions having a relatively large difference in the gear ratio between the gear positions is set to be larger than the determination value between the gear positions having a relatively small difference in the gear ratio between the gear positions.Type: GrantFiled: September 5, 2019Date of Patent: July 18, 2023Assignee: NISSAN MOTOR CO., LTD.Inventors: Sergio Rossi, Michiharu Gunji

Patent number: RE49598Abstract: A vehicle HVAC noise control system includes an air handler, a blower motor, an audio event device and a controller. The air handler is connected to a passenger compartment. The blower motor is operably connected to the air handler to provide a plurality of airflow rates for air flowing into a passenger compartment. The audio event device produces an audio event to the passenger compartment. The controller is operatively connected to the blower motor and the audio event device. The controller controls operation of the blower motor initially at an operating airflow rate and subsequently switches to a noise reducing airflow rate in response to a signal from the audio event device indicating that the audio event device will subsequently produce the audio event.Type: GrantFiled: January 8, 2020Date of Patent: August 8, 2023Assignee: Nissan Motor Co., Ltd.Inventors: Ronald S Eisenhour, Adrian Tan
