Publication number: 20150224970Abstract: In a vehicle brake control device for generating rear wheel braking torque by an electric motor, “slip suppression control of the rear wheel” for reducing rear wheel braking torque by controlling the electric motor is executed based on a slip state quantity of the rear wheel. Further, “sudden-stop control” for rapidly stopping electric motor rotation motion is executed based on a slip state quantity of a front wheel. The sudden-stop control is executed when rear wheel slip suppression control is not being executed. As the sudden-stop control, “control for changing an energization amount of the electric motor stepwise to an energization limit value set in advance corresponding to a deceleration direction of the electric motor” may be executed. Accordingly, it is possible to suppress excessive rear wheel slip due to inertia influences or the like of the electric motor when execution of the rear wheel slip suppression control is started.Type: ApplicationFiled: September 4, 2013Publication date: August 13, 2015Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, ADVICS CO., LTD.Inventors: Yoshiyuki Yasui, Hiroyuki Kodama, Takuya Hirano, Naoki Yabusaki, Takayuki Yamamoto

Patent number: 8165298Abstract: In a quantum cryptography communication apparatus, a light pulse is generated by a light source and split into a signal light pulse and a reference light pulse on a receiving side. The signal light pulse and the reference light pulse are transmitted to a sending side via a communication channel. On the sending side, the received reference light is passed through a first optical path and phase-modulated by a randomly selected amount. Communication information is acquired on the basis of the reference light passed through the first optical path and the signal light passed via a second optical path. Frequencies of the signal light pulse and the reference light pulse are shifted. The intensity of the signal light pulses is attenuated and phase-modulated by an amount corresponding to the communication information. The resultant signal light pulse and the reference light pulse are returned back to the receiving side.Type: GrantFiled: February 15, 2008Date of Patent: April 24, 2012Assignee: Sony CorporationInventors: Yohei Kawamoto, Takuya Hirano, Kuninori Shino, Masakazu Ukita
