Publication number: 20210056781Abstract: A storage device in a vehicle stores practical mapping data and evaluation mapping data, and a CPU determines a presence or absence of a misfire based on a mapping defined by each of the mapping data. When there is a mismatch between two determination results, the CPU transmits, to a data analysis center, data used as an input of the mapping defined by the evaluation mapping data. The data analysis center verifies a validity of the determination result using the evaluation mapping data.Type: ApplicationFiled: August 10, 2020Publication date: February 25, 2021Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yohsuke HASHIMOTO, Akihiro KATAYAMA, Yuta OSHIRO, Kazuki SUGIE, Naoya OKA

Publication number: 20200264074Abstract: A state detection system for an internal combustion engine is provided. A detection mapping takes, as inputs, rotation waveform variables and a road surface state variable to output a combustion state variable. The rotation waveform variables include information on a difference between cylinders in the rotational speed NE of a crankshaft during periods in which the respective cylinders generate combustion torque. The combustion state variable relates to a level of variations in combustion state among the cylinders. A determination process performed by an execution device determines whether the internal combustion engine is in a predetermined operating state based on an output value of the detection mapping that takes, as inputs, values of the rotation waveform variables and a value of the road surface state variable.Type: ApplicationFiled: February 10, 2020Publication date: August 20, 2020Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yosuke HASHIMOTO, Akihiro KATAYAMA, Yuta OSHIRO, Kazuki SUGIE, Naoya OKA

Publication number: 20200263617Abstract: A state detection system for an internal combustion engine is provided. Rotation waveform variables include information on a difference between cylinders in the rotational speed of a crankshaft during periods in which the respective cylinders generate combustion torque. An obtainment process obtains a value of the rotation waveform variables and a value of a road surface state variable based on an output of a sensor that detects a state of the road surface. A selection process selects, from a plurality of types of mapping data stored in the storage device, the mapping data that is associated with the road surface state variable as the detection mapping. A determination process determines whether the engine is in a predetermined operating state based on an output value of the selected detection mapping that takes the rotation waveform variables as inputs.Type: ApplicationFiled: February 10, 2020Publication date: August 20, 2020Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yosuke HASHIMOTO, Akihiro KATAYAMA, Yuta OSHIRO, Kazuki SUGIE, Naoya OKA
