Publication number: 20190226440Abstract: When an engine is stopped, a rotational position at a time when a crankshaft starts rotating in a reverse direction is predicted based on a rotational position detected by a crank angle sensor. A target rotational position is set within a range of the crankshaft rotational position between a time when the exhaust valve of one of four cylinders in the expansion stroke when the crankshaft starts rotating in the reverse direction is opened and a time when the expansion stroke of the cylinder ends. When the predicted rotational position is behind the target rotational position, a torque applying device applies a positive rotational torque to the crankshaft. At the time when the exhaust valve of the cylinder in the expansion stroke when the crankshaft starts rotating in the reverse direction is opened, application of the positive rotational torque from the torque applying device to the crankshaft is stopped.Type: ApplicationFiled: November 29, 2018Publication date: July 25, 2019Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Koji MURAKAMI

Publication number: 20190210588Abstract: When the state of charge of a battery is greater than or equal to a lower limit value and less than or equal to an upper limit value, an electronic control unit calculates a charging electric energy transferred between a motor-generator and the battery such that the battery is neither charged nor discharged. When the state of charge is less than the lower limit value, a required torque of the engine is calculated based on the charging electric energy, a power consumption of an auxiliary device, and a driving torque. When the state of charge is greater than or equal to the lower limit value and less than or equal to the upper limit value, the required torque is calculated based on the charging electric energy and the driving torque, without taking the power consumption into consideration.Type: ApplicationFiled: November 30, 2018Publication date: July 11, 2019Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koji Murakami, Hiroshi Sato

Patent number: 9970403Abstract: When a start condition is satisfied after the internal combustion engine has been stopped according to an automatic stop control, a control apparatus reversely rotates the engine to compress an air in an expansion stroke cylinder at that time point, and thereafter generates a first time combustion. The apparatus determines whether the start condition becomes satisfied based on a first start request owing to a driving operation by a driver of a vehicle on which the engine is mounted. When the start condition becomes satisfied based on the first start request, the control apparatus makes a maximum value of an engine generating torque by the first time combustion and/or a maximum torque of the engine generating torque by a second time combustion larger as compared to when the start condition becomes satisfied based on a second start request other than the first start request.Type: GrantFiled: August 22, 2017Date of Patent: May 15, 2018Assignee: Toyota Jidosha Kabushiki KaishaInventors: Naoki Hayashima, Mitsuhiro Tabata, Koji Murakami, Tomoya Takahashi
