Publication number: 20130274980Abstract: Provided herein is a vehicle drive force control. When a driver requests to start the vehicle with the brake OFF and depresses the accelerator pedal, a target drive torque exceeds a gradient load. To avoid excess current being supplied to the motor, the upper limit of motor speed, which is the input speed of a second clutch, is set to a value less than a slip detectable limit value at which it becomes possible to detect slip rotation, i.e. the difference over the output side rotation speed. When the target drive torque exceeds the gradient load, the lower limit of the input speed of the second clutch (the motor speed) is set to a value equal to or greater than the slip detectable limit value so that the required driving force can be achieved by the gradient load corresponding driving force control.Type: ApplicationFiled: October 20, 2011Publication date: October 17, 2013Applicant: Nissan Motor Co., Ltd.Inventors: Yutaka Takamura, Hiroshi Arita, Harushisa Tsuchikawa, Hiroki Shimoyama

Patent number: 8423661Abstract: A transmit packet generated by a CPU 1 is held in a buffer 100a (100b). From among packets received from Ethernet 820a (820b), a packet, a destination of which is a communication device 800, is held in the buffer 100a (100b). A packet which should be transmitted is transmitted from a transfer judging circuit 200 to Ethernet 820a or 820b through a MAC unit 300a or 300b. If a transfer judging circuit 200 judges a packet from the Ethernet 820a to be a packet, a destination of which is another communication device, with reference to a destination MAC address, this packet is transferred to the Ethernet 820b through MAC 300b. If a usage rate of a transferring FIFO buffer 130a (130b) exceeds a threshold value in the process of transmitting a packet held in a transmitting FIFO buffer 120a (130b) on a priority basis, the priority order of a transfer packet is made higher than that of a transmit packet so that the transfer packet is transferred to the Ethernet 820a or 820b in preference to the transmit packet.Type: GrantFiled: September 1, 2010Date of Patent: April 16, 2013Assignees: Renesas Electronics Corporation, Hitachi Information & Control Solutions, Ltd.Inventors: Hiroshi Arita, Yasuhiro Nakatsuka, Yasuwo Watanabe, Kei Ouchi, Yoshihiro Tanaka, Toshinobu Kanai, Masanobu Tanaka, Kenji Furuhashi, Tomoaki Aoki

Patent number: 7808397Abstract: A sensor transmits and receives wireless signals at intervals. A sensor unit, a processor 130, a wireless transmitter circuit, and a wireless receiver circuit are activated in sequence only for a fixed time when the electric power generated by a generator circuit and charged in a capacitor reaches a preset level. Sensing information detected by the sensor unit is processed by the processor circuit and, information on the number of receivable bytes is added to the processing results in the wireless receiver circuit. This added information is sent as sensor information to the wireless host from the wireless transmitting circuit, and the wireless receiver circuit that activated after the wireless transmitter circuit was activated, receives a control information signal from the wireless host. This received information is processed in the processor circuit.Type: GrantFiled: July 3, 2007Date of Patent: October 5, 2010Assignee: Hitachi, Ltd.Inventors: Hiroshi Arita, Masaru Kokubo, Kenichi Mizugaki

Patent number: 7558483Abstract: The system includes optical bus-bridging devices for observing the modes of said electric buses and the modes of said optical fibers while said electric buses have not been driven (OFF mode), so that the modes of the two electric buses connected through optical fibers are brought into agreement and that the buses can be simultaneously driven by a plurality of nodes. While one or both of said electric buses have been driven (ON mode) by the nodes connected thereto, an optical output has been continuously produced from the buses that are being driven to said optical fibers, and while light has been inputted from said optical fibers, the modes of said buses are not observed, but an electric output is produced to the electric bus of the side to which light is inputted to drive the bus. The optical bus-bridging device changes the mode of the electric bus when the optical fiber does not change within a predetermined period of time after the optical bus-bridging device has outputted a signal to the optical fiber.Type: GrantFiled: July 23, 2004Date of Patent: July 7, 2009Assignee: Hitachi, Ltd.Inventors: Hiroshi Arita, Tetsuaki Nakamikawa, Kenichi Kurosawa, Hiroaki Fukumaru, Hisao Ogawa
