Patent number: 8595275Abstract: The present invention is directed to improve leak analysis resistance by improving randomness of a pseudorandom number. A pseudorandom number generator as a representative embodiment of the invention includes a shift resistor obtained by coupling a plurality of flip flop circuits and can generate a pseudorandom number by shifting signals by the shift register synchronously with a clock signal. A shift amount changing circuit capable of changing a shift amount in the shift register in accordance with a control signal supplied from the outside of the pseudorandom number generator is provided. By changing the shift amount in the shift register in accordance with a control signal supplied from the outside of the pseudorandom number generator by the shift amount changing circuit, it becomes difficult to make outputs of the pseudorandom number generator the same. By using such a pseudorandom number generator, leak analysis resistance can be improved.Type: GrantFiled: April 10, 2009Date of Patent: November 26, 2013Assignee: Renesas Electronics CorporationInventors: Yuichiro Nariyoshi, Takashi Endo, Seiji Kobayashi

Publication number: 20130247543Abstract: An exhaust gas control apparatus includes a control device controlling a urea addition valve for adding urea from an upstream side of a NOx reduction catalyst. The control device obtains an ammonia adsorption amount distribution through the NOx reduction catalyst. When an ammonia adsorption amount in a predetermined part on a downstream side equals or exceeds a predetermined threshold, the control device controls the urea addition valve to stop the urea supply or reduce the amount thereof. The urea addition valve is controlled based on an adsorption amount distribution obtained from a model on which the catalyst is divided into cells such that an ammonia adsorption amount in a first cell positioned furthest upstream equals or exceeds a predetermined threshold close to a saturation adsorption amount and an ammonia adsorption amount in a second cell positioned downstream of the first cell reaches a predetermined target value smaller than the threshold.Type: ApplicationFiled: September 21, 2011Publication date: September 26, 2013Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, KABUSHIKI KAISHA TOYOTA JIDOSHOKKI, DENSO CORPORATIONInventors: Shinya Hirota, Shunsuke Toshioka, Akira Mikami, Koichiro Fukuda, Sakutaro Hoshi, Takashi Endo, Ryoichi Hibino, Matsuei Ueda, Akihiko Asano, Takafumi Yamauchi, Akira Shichi, Makoto Koike, Masatoshi Maruyama, Masakazu Sakata
