Publication number: 20230150501Abstract: The posture of the driver is detected from the driver head portion, and the detected value and the driver mounting determination value are used to determine that the driver is pushing the vehicle and obtain the vehicle pushing command value. Converts the vehicle pushing command value to the target vehicle pushing assistance vesicle speed, determines whether vehicle pushing assistance can be performed based on the driver's posture and the vehicle condition, and outputs the vehicle pushing assistance permission determination. Then, from the target vehicle pushing assistance vehicle speed and the vehicle pushing assistance permission determination, the control amount for the vehicle power source that assists the vehicle pushing is calculated and output.Type: ApplicationFiled: April 8, 2022Publication date: May 18, 2023Applicant: Mitsubishi Electric CorporationInventors: Takuma Kusagaki, Tatsuo Fujimoto, Nobuyoshi Tomomatsu, Taiga Tanaka, Tatsuji Irie, Wataru Tsujita, Kenzo Makino

Publication number: 20220402488Abstract: The objective is to improve driving feeling at a time of acceleration operation or deceleration operation, by recognizing driver's intention of acceleration or deceleration during straight-ahead running. A driving-assistance control apparatus according to the present disclosure includes a straight-running determination unit that determines whether or not a vehicle is running straight, a head-position detection unit that detects a head position of a driver, a driving-posture determination unit that determines the posture of the driver, based on the head position detected by the head-position detection unit, and a driving-assistance control unit that performs acceleration preparation control for raising a reaction speed for acceleration operation or deceleration preparation control for raising a reaction speed for deceleration operation in accordance with an output of the driving-posture determination unit, when the straight-running determination unit determines that a vehicle is running straight.Type: ApplicationFiled: April 29, 2022Publication date: December 22, 2022Applicant: Mitsubishi Electric CorporationInventors: Tatsuo Fujimoto, Nobuyoshi Tomomatsu, Takuma Kusagaki, Taiga Tanaka, Tatsuji Irie, Wataru Tsujita, Kenzo Makino

Patent number: 11454184Abstract: The control device for an internal combustion engine disclosed in the present application is a control device that determines the presence or absence of misfire based on an angle detection cycle calculated from an output signal of an angle sensor, the control device includes an arithmetic processing device and a storage device, the control device is configured so that the storage device stores the angle detection cycle calculated in a misfire detection threshold value comparison section after the reference angle section as a threshold value comparison target cycle and is configured such that the arithmetic processing device determines the presence or absence of misfire based on the misfire detection threshold value cycle calculated based on the reference detection cycle and the threshold value comparison target cycle, thereby it becomes possible to accurately determine the presence or absence of misfire in the control device for the internal combustion engine.Type: GrantFiled: March 25, 2020Date of Patent: September 27, 2022Assignee: Mitsubishi Electric CorporationInventors: Tatsuo Fujimoto, Nobuyoshi Tomomatsu, Takuma Kusagaki, Kenichi Yamagata, Kenichiro Yonezawa, Siyu Liu

Patent number: 10989627Abstract: To provide a controller for an internal combustion engine which can determine presence or absence of misfire with good accuracy, even when the rotational variation occurs due to factors other than misfire. A controller for an internal combustion engine calculates, as a reference detection period, the detection period detected within a reference angle interval including a top dead center; calculates a period deviation which is a deviation between the reference detection period and the each detection period; calculates a former period deviation integration value by integrating the period deviation in a former angle interval before the top dead center; calculates a later period deviation integration value by integrating the period deviation in a later angle interval after the top dead center; and determines presence or absence of misfire in the combustion stroke based on the former period deviation integration value and the later period deviation integration value.Type: GrantFiled: April 26, 2019Date of Patent: April 27, 2021Assignee: Mitsubishi Electric CorporationInventors: Tatsuo Fujimoto, Nobuyoshi Tomomatsu, Kenichiro Yonezawa, Kenichi Yamagata, Takuma Kusagaki
