Patent number: 10378468Abstract: A misfire detecting apparatus for an internal combustion engine is provided. The engine has an output shaft connected via a torsion element to an input shaft of a transmission mechanism. A transmission rotational speed parameter indicative of a rotational speed of the input shaft is detected. A modified engine rotational speed parameter is calculated by modifying the detected engine rotational speed parameter based on the transmission rotational speed parameter, an engine rotation moment on the input side of the torsion element, and a transmission rotation moment on the output side of the torsion element. An average change amount of the modified rotational speed parameter, and an inertia speed changing component, are calculated. Further, a corrected rotational speed parameter is calculated by correcting the modified rotational speed parameter according to the average change amount and the inertia speed changing component.Type: GrantFiled: March 2, 2012Date of Patent: August 13, 2019Assignee: HONDA MOTOR CO., LTD.Inventors: Keisuke Minatoya, Atsushi Izumiura, Tadayoshi Sasaki, Shigetaka Kuroda, Mahito Shikama

Patent number: 10266179Abstract: The intent to exit a vehicle when a driver attempts to exit a vehicle is detected by an exit intent detection unit, and regardless of whether or not the shift range other than the parking range is detected by a shift range detection unit, a securing control unit controls a vehicle securing unit and secures the vehicle when an intent to secure is detected by a securing intent detection unit. Thus, unintended vehicle movement after exiting is suppressed by securing the vehicle in a stopped state during exiting.Type: GrantFiled: September 3, 2015Date of Patent: April 23, 2019Assignee: Honda Motor Co., Ltd.Inventors: Kanta Tsuji, Mahito Shikama
