Patent number: 6651436Abstract: A control apparatus for a hybrid vehicle of the present invention determines whether a brake switch flag F_BKSW is “1” or not (step S101), and in the case where the brake is on (“yes”), obtains a deceleration regeneration computation value DECRGN by table retrieval from a #REGENBR table. In the case where the brake is off (“no”), it is determined whether a fuel supply cut delay time regeneration flag F_RGNFCD is “1” or not (step S104). In the case where regeneration is not performed in the fuel supply cut delay time (“no”), a deceleration regeneration computation value DECRGN is obtained by table retrieval from a #REGEN table (step S105). On the other hand, in the case where regeneration is performed in the fuel supply cut delay time (“yes”), a deceleration regeneration computation value DECRGN is obtained by table retrieval from a #RGNNFCD table (step S106).Type: GrantFiled: March 28, 2002Date of Patent: November 25, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Atsushi Izumiura, Asao Ukai, Shinichi Kitajima, Futoshi Nishioka, Fumihiko Konno

Patent number: 6550557Abstract: A control apparatus provided in a hybrid vehicle having a combustion engine for outputting a driving force, an electric motor for generating a force for assisting the output from the engine, depending on the driving conditions, a power storage unit for storing electric energy generated by the motor acting as a generator using the output from the engine and electric energy regenerated by the motor when the vehicle decelerates. The control apparatus includes: a speed limiter for decreasing the driving force produced by the motor when the vehicle speed exceeds a first threshold value while the engine and the motor produce the driving force; a generation starter for starting generation by the motor when the vehicle speed exceeds a second threshold value which is higher than the first threshold value; and a generation amount setting device for setting the amount of generation, depending on the driving conditions of the vehicle, when the generation starter starts the generation.Type: GrantFiled: December 18, 2000Date of Patent: April 22, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Teruo Wakashiro, Kazutomo Sawamura, Shinichi Kitajima, Hideyuki Takahashi, Katsuhiro Kumagai, Fumihiko Konno

Patent number: 6450274Abstract: A control device for a hybrid vehicle powered from an engine and an assist motor for supplying electric power in an amount predetermined according to running conditions of the vehicle further includes means for detecting a catalyzer temperature and correcting the predetermined assist power value according to the detected catalyzer temperature when accelerating and means for preventing the idling engine from being cut off when detected catalyzer temperature is lower than a preset temperature. This control device thus realizes rapid heating of the catalyzer device to a temperature necessary for activating the catalyzer therein by adequately correcting the assist power value of the motor according to the current catalyzer temperature when accelerating and by preventing the idling engine from being cut off while the catalyzer device has a low temperature.Type: GrantFiled: September 15, 1999Date of Patent: September 17, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Fumihiko Konno, Shigetaka Kuroda, Youichi Iwata, Asao Ukai, Takashi Kiyomiya, Kenji Nakano, Atsushi Matsubara, Yasuo Nakamoto
