The processing circuitry is configured to execute an estimation process that estimates a density parameter of fuel in an upper layer portion of a delivery pipe and a density parameter of fuel in a lower layer portion of the delivery pipe and an operation process that includes acquiring a density parameter of the fuel injected from a fuel injection valve and operating an operation unit of the internal combustion engine based on the acquired density parameter. The estimation process includes a process that assumes that when the density of the fuel flowing into the delivery pipe is high, a greater proportion of the fuel flowing into the delivery pipe flows into the lower layer portion than when the density of the fuel flowing into the delivery pipe is low.Type: GrantFiled: July 17, 2019Date of Patent: August 11, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryusuke Kuroda, Masahiro Ozeki, Masanao Idogawa

Patent number: 10731543Abstract: A method of determining whether a block heater has been used prior to starting an internal combustion engine includes monitoring the temperature with time of the intake air subsequent to the start of the engine. The method also includes determining whether there is a subsequent drop in the temperature after starting. If a temperature drop is determined, a parameter of the temperature drop with time is determined. If the parameter becomes larger than a predetermined threshold, block heater use is indicated.Type: GrantFiled: June 13, 2019Date of Patent: August 4, 2020Assignee: DELPHI AUTOMOTIVE SYSTEMS LUXEMBOURG SAInventors: Eduardo Maiello, Erik Schoof, Loic Gandolfi, Luca Tascedda

Patent number: 10598117Abstract: An injector driving device includes a control circuit of a booster circuit that charges a capacitor by repeatedly switching a booster switch ON/OFF during a voltage boost control to cause a reverse voltage in a coil, and stops the voltage boost control upon determining that a capacitor voltage has reached a corrected target value. The control circuit detects a peak value of the capacitor voltage during an OFF period of the boost switch. The control circuit also detects a capacitor voltage as an ON value during the subsequent ON period of the booster switch. A difference between the peak voltage and the ON value of the capacitor is calculated, and a post-correction target value is set by adding the difference to a reference value of a target value.Type: GrantFiled: September 14, 2018Date of Patent: March 24, 2020Assignee: DENSO CORPORATIONInventor: Hiroki Nambu

Patent number: 10539081Abstract: An internal-combustion engine control apparatus is obtained which can accurately perform the control toward an output target value by calculating an exhaust gas temperature more accurately, and eliminating discrepancies of a turbine flow-rate and a waste-gate-valve opening-degree. In the apparatus, a thermal efficiency calculation unit calculates thermal efficiency based on a combination in any of ignition timing, charging efficiency, an air-fuel ratio and an exhaust gas recirculation (EGR) ratio being change factors in thermal efficiency of the internal-combustion engine; an exhaust-gas loss calculation unit calculates exhaust gas loss based on thermal efficiency calculated by the thermal efficiency calculation unit, and on a combination in any of the change factors of the exhaust gas loss; and an exhaust port temperature calculation unit calculates an exhaust gas temperature at an exhaust port portion based on exhaust gas loss calculated by the exhaust-gas loss calculation unit.Type: GrantFiled: October 6, 2017Date of Patent: January 21, 2020Assignee: Mitsubishi Electric CorporationInventors: Tatsuhiko Takahashi, Takahiko Ono

Patent number: 10519882Abstract: An internal combustion engine comprises a fuel injector, a spark plug, an evaporated fuel purge device purging evaporated fuel in the fuel tank into an intake passage, and a control device. The control device can perform spark assist control for sequentially injecting premix-forming fuel and injecting ignition assist fuel from the fuel injector, while controlling the fuel injector and spark plug so as to make an air-fuel mixture formed by the injection of ignition assist fuel burn by the spark plug by flame propagation and to make the remaining fuel burn using the heat released by the flame propagation combustion by premixed compression self-ignition, and the control device makes the injection amount of premix-forming fuel decrease without changing the injection amount of ignition assist fuel when purging evaporated fuel into the intake passage by the evaporated fuel purge device compared to when not purging it.Type: GrantFiled: April 19, 2018Date of Patent: December 31, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Satoshi Tsuda

Patent number: 10487759Abstract: A fuel injection controller for an internal combustion engine selects as the injection mode either single injection or split injection, counts, based on a drive current detection signal, which indicates that a drive current is generated to be fed to the direct injector, the number of occurrences of the drive current in one combustion cycle as a number-of-injections count value, and determines, based on the number-of-injections count value, whether the combustion state in the cylinder is satisfactory. The fuel injection controller determines that the combustion state in the cylinder is unsatisfactory if the number-of-injections count value in one combustion cycle is one when catalyst warm-up control is being performed with the temperature of the engine being lower than or equal to a predetermined temperature.Type: GrantFiled: February 26, 2018Date of Patent: November 26, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuki Ikejiri, Yoshihisa Oda

Patent number: 10467323Abstract: There is provided a method of updating a setting value of a variable parameter, the method including: obtaining a time-series data of control input and a time-series data of control output observed in control with a controller; calculating a value of the variable parameter which minimizes an output value of an evaluation function based on the obtained time-series data of the control input and the control output; and updating the setting value of the variable parameter to the calculated value of the variable parameter. The evaluation function includes a first function part in which a first norm or a second norm changes depending on the value of the variable parameter, and a second function part of which specific frequency band has an amount, by which the output value of the evaluation function is increased, larger than that of any other frequency band.Type: GrantFiled: September 29, 2016Date of Patent: November 5, 2019Assignee: Brother Kogyo Kabushiki KaishaInventor: Eisuke Takahashi
