Patent number: 10947908Abstract: A controller according to the present disclosure, in each combustion cycle that composes a change cycle, calculates the average ?n of control amounts from the first combustion cycle to the nth (1<=n<=N) combustion cycle and calculates the error ?n-?o of the average ?n with respect to the average ?o of a reference normal population. Also, the controller sets both a positive threshold Z?/2*?o/n1/2 and a negative threshold ?Z?/2*?o/n1/2 based on the standard error ?o/n1/2 of the reference normal population in the case where the number of data is n. Then, the controller chooses an operation amount to be changed from a plurality of operation amounts, based on a comparison between a series of the errors ?n-?o and a series of the positive thresholds Z?/2*?o/n1/2 and a comparison between the series of the errors ?n-?o and a series of the negative thresholds ?Z?/2*?o/n1/2.Type: GrantFiled: April 24, 2019Date of Patent: March 16, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shigeyuki Urano, Kota Sata

Patent number: 10895217Abstract: Provided is a control apparatus for an internal combustion engine which can achieve required torque and avoid the risk of an accidental fire even in the case where an error occurs in final injection termination timing. A microcomputer calculates T902 which has been further advanced from T106 which precedes ignition timing by time required for vaporization of fuel injected into a cylinder of an internal combustion engine. The microcomputer determines whether final injection termination timing (T903) comes after T106 or T902. When it has been determined that final injection termination timing (T1204) comes after T106 or T902, the microcomputer controls an injector or an ignition device so as to secure time for vaporization of the fuel injected into the cylinder of the internal combustion engine while satisfying a fuel injection amount required in one combustion cycle.Type: GrantFiled: January 19, 2017Date of Patent: January 19, 2021Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Osamu Mukaihara, Masahiro Toyohara, Shigeyuki Yufu

Patent number: 10837417Abstract: A control apparatus controls the operation of a starter such that, after an idling stop is executed and before a request for starting an engine is subsequently issued, the control apparatus executes a preset which causes a pinion to engage a ring gear. A control apparatus controls the operation of a starter such that, after an idling stop is executed and before a request for starting an engine is subsequently issued, the control apparatus executes a preset which causes a pinion to engage a ring gear. It is determined that the preset condition has been cancelled, and the preset is again executed. In that case, the pinion is already engaged with the ring gear at the time point when a request for starting the engine is issued. In that way it is unnecessary for the control apparatus to push out the pinion after a start request is issued.Type: GrantFiled: January 25, 2017Date of Patent: November 17, 2020Assignee: DENSO CORPORATIONInventors: Yoshitomo Takeuchi, Atsuyuki Hiruma, Akira Yamada, Akihiro Imura, Takuro Nakaoka
