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

Patent number: 9616878Abstract: A control apparatus is applied to a hybrid vehicle. The hybrid vehicle includes an MG which is connected with an input shaft of a manual transmission via a first clutch that is operated by a press operation to a clutch pedal and an internal combustion engine which is connected with the MG via a second clutch. The hybrid vehicle is allowed to execute an EV traveling mode where: the internal combustion engine is stopped; the internal combustion engine and drive wheels are separated by the second clutch; and the drive wheels are driven by the MG. In the control apparatus, when the EV traveling mode is executed, a required torque is obtained based on an accelerator opening degree, and a required transmission torque is obtained based on an operation amount to the clutch pedal. And, when a smaller one of the required torque and the required transmission torque is greater than a determination value, the internal combustion engine is started.Type: GrantFiled: January 8, 2014Date of Patent: April 11, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takaaki Tanaka, Mitsuhiro Tabata
