Patent number: 11380103Abstract: A surveillance performance (information expressing uncertainty of information relating to a potential risk area in a region that requires monitoring) and a tracking performance (information expressing the product of an importance level of a potential risk area and a coverage ratio (an overlap rate between potential risk areas and moving bodies)) are mutually analyzed, and plural moving bodies are allotted to either surveillance or tracking. Potential risk areas that require monitoring are determined such that the surveillance performance and the tracking performance respectively satisfy predetermined levels. The plural moving bodies are allocated to potential risk areas determined to be potential risk areas that require monitoring (simultaneous optimization). The respective moving bodies subject to simultaneous optimization start moving toward their allocated potential risk areas to monitor the potential risk areas.Type: GrantFiled: June 28, 2018Date of Patent: July 5, 2022Assignee: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHOInventors: Tatsuya Miyano, Kazuki Shibata, Tomohiko Jimbo

Patent number: 10356367Abstract: A blind spot coverage device that includes: a sensor section that senses external environmental information; a definition section that defines an external environmental region, in which sensing information is unobtainable, as a blind spot region; a determination section that determines whether or not the blind spot region is to be covered; and an instructing section that, in a case in which the determination section determines that the blind spot region is to be covered, instructs an actuator to move such that the blind spot region is covered. The determination section determines that the blind spot region is to be covered in a case in which determination is made that the blind spot region lacks global coverage.Type: GrantFiled: November 28, 2017Date of Patent: July 16, 2019Assignee: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHOInventors: Tatsuya Miyano, Kazuki Shibata, Tomohiko Jimbo

Patent number: 9499158Abstract: When a drive shaft (37) is driven while the operation of an engine (36) is stopped, the rotation of an input-side rotor (28) is restricted by the engagement of a brake. Further, on the basis of the temperature Temp_SR of a brush (96) acquired by a temperature sensor (97), the distribution of torque Tcoup acting between the input-side rotor (28) and the first output-side rotor (18) and torque Tmg acting between the stator (16) and the second output-side rotor (19) is controlled. Consequently, drive performance when the drive shaft (37) is driven while the operation of the engine (36) is stopped is improved while local overheating of a slip ring (95) is prevented.Type: GrantFiled: November 8, 2013Date of Patent: November 22, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takao Watanabe, Eiji Tsuchiya, Tatsuya Miyano, Akira Murakami, Takahiro Shiina, Tadashi Fujiyoshi

Patent number: 9457670Abstract: In a power generation control apparatus applied to a hybrid vehicle including a compound motor in which a wound rotor is connected to an internal combustion engine and a magnet rotor is connected to a transmission, when regenerative power generation is underway and the internal combustion engine is operative, a first motor/generator constituted by the wound rotor and the magnet rotor and the internal combustion engine are controlled such that torque output from the internal combustion engine is increased by torque applied to the internal combustion engine from the first motor/generator, and a power generation amount of a second motor/generator constituted by the magnet rotor and a stator is increased such that torque transmitted to an output shaft from the internal combustion engine is not applied to a drive wheel.Type: GrantFiled: June 4, 2012Date of Patent: October 4, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tadashi Fujiyoshi, Takahiro Shiina, Akira Murakami, Tatsuya Miyano, Takao Watanabe, Ryoichi Hibino

Patent number: 8914179Abstract: During an inertial energy storage operation, electric power conversion at an inverter is controlled such that a direct current electric power from an electric power storage device is converted into an alternating current by the inverter so as to be supplied to stator windings, such that torque in the direction of engine rotation is applied to an output side rotor from a stator to rotatively drive the output side rotor in a state where power transmission from the output side rotor to a drive axle is stopped. During a cranking operation after the inertial energy storage operation, the electric power conversion at an inverter is controlled to permit application of the alternating current to rotor windings, such that a torque in the direction of engine rotation is applied to an input side rotor from the output side rotor, thereby rotatively driving an input side rotor to crank the engine.Type: GrantFiled: March 27, 2012Date of Patent: December 16, 2014Assignees: Kabushiki Kaisha Toyota Chuo Kenkyusho, Toyota Jidosha Kabushiki Kaisha, Aisin Seiki Kabushiki KaishaInventors: Eiji Tsuchiya, Takao Watanabe, Shu Asami, Tatsuya Miyano, Akira Murakami, Hiroyuki Ogawa, Tomoyuki Toyama
