Publication number: 20240134720Abstract: An apparatus including a processor, with processing circuitry configured to obtain a parameter at a time when a system call function is called by a system call; call a first system call function from a kernel, and returning a processing result of the first system call function, when a processing target in the first system call function to be called that is indicated by the parameter is not a monitoring target that affects an identity of data to be protected; and return a result as in a case where processing by the first system call function is successfully executed, or a processing result indicating an error, without calling the first system call function, when the processing target in the first system call function to be called that is indicated by the parameter is the monitoring target.Type: ApplicationFiled: December 11, 2023Publication date: April 25, 2024Applicant: DIGITAL INFORMATION TECHNOLOGIES CORPORATIONInventors: Noritaka IIJIMA, Tsutomu NAKAJIMA, Koji ONISHI

Patent number: 10598268Abstract: A support structure of a vehicle drive system unit includes a unit case having a plurality of case members provided with abutting portions at axial opening ends, the abutting portions axially abutted against and bolt-fastened to each other to integrally couple the plurality of case members, one of the plurality of case members as a fixing case member being fixed via a supporting member to a body-side supporting portion. In the support structure, a reinforcing stiffener is disposed on the outside of the unit case so as to couple at least one of the abutting portion of the fixing case member and the abutting portion of another case member abutted against and bolt-fastened to the abutting portion of the fixing case member, and the supporting member or the body-side supporting portion to which the supporting member is fixed.Type: GrantFiled: April 16, 2018Date of Patent: March 24, 2020Assignee: Toyota Jidosha Kabushiki KaishaInventors: Noritaka Nakajima, Hiroshi Kawanishi

Patent number: 9242634Abstract: The control device of the present invention causes an engine to perform both partial cylinder operation and also all-cylinder operation, and moreover changes the operating point of the engine when the motor torque of a second motor-generator enters into operating point changeover ranges R1 and R2. The operating point changeover range R2 when the engine is performing partial cylinder operation is set to be wider, as compared to the operating point changeover range R1 when the engine is performing all-cylinder operation.Type: GrantFiled: November 30, 2012Date of Patent: January 26, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Satoru Takahashi, Takeshi Miyagawa, Noritaka Nakajima, Kouki Kawamoto, Daiki Sato, Masato Nakano, Akihiro Sato, Takeshi Kanayama, Shinichiro Suenaga

Patent number: 9020678Abstract: A drive control device for a hybrid vehicle is provided with a differential device including four rotary elements; and an engine, first and second electric motors and an output rotary member which are respectively connected to the four rotary elements. One of the four rotary elements is constituted by a rotary component of a first differential mechanism and a rotary component of a second differential mechanism selectively connected through a clutch, and one of the rotary components is selectively fixed to a stationary member through a brake. The drive control device comprises a mode selecting operation device selecting an acceleration drive mode oriented to vehicle acceleration and a fuel efficiency drive mode oriented to fuel efficiency.Type: GrantFiled: March 26, 2012Date of Patent: April 28, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventor: Noritaka Nakajima

Publication number: 20150047915Abstract: Provided is a hybrid vehicle drive control device that achieves appropriate limp-home driving in the event of a clutch failure. The drive control device is equipped with: a clutch (CL) that connects/disconnects the carrier (C1) of a first planetary gear train (14) and the carrier (C2) of a second planetary gear train (16); and a brake (BK) that connects/disconnects said carrier (C2) to/from a housing (26). In the event of a failure in which the clutch (CL) is released in the absence of a control command, limp-home driving is performed while the brake (BK) is engaged. Consequently, appropriate limp-home driving can be enabled by minimizing unnecessary consumption of energy by a first electric motor (MG1) and a second electric motor (MG2).Type: ApplicationFiled: March 26, 2012Publication date: February 19, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Satoshi Kasamai, Noritaka Nakajima
