Patent number: 9387736Abstract: A system for detecting deflated tires by making a relative comparison among rotation speeds of tires attached to a vehicle. The system includes a rotation speed information detection means for detecting rotation speed information of the tires; a rotation speed calculation means for calculating rotation speeds of the tires; and a determination means for determining deflated tires by comparing a decreased pressure determination value using the calculated rotation speeds with a predetermined threshold value. The determination means determines that the vehicle is going straight when it is found, with regard to factors composed of a lateral G, a yaw rate, and a steering angle of the vehicle, at least two of the factors including the yaw rate show that a difference between the maximum value and the minimum value at a predetermined time is lower than a predetermined value, thereby detecting deflated tires.Type: GrantFiled: June 1, 2012Date of Patent: July 12, 2016Assignees: SUMITOMO RUBBER INDUSTRIES, LTD., HONDA MOTOR CO., LTD.Inventors: Minao Yanase, Seigou Sakagami, Yuji Oshiro, Tomonori Sakai, Shinya Notomi, Kazutaka Saito, Kazunari Okada, Ichiro Ueno

Patent number: 8726724Abstract: A system detects deflated tires based on a resonance frequency of tires with a vehicle and a relative comparison value of rotation speeds of the tires. The system includes: a rotation information detection means for detecting rotation information of the tires; a rotation speed calculation means for calculating rotation speeds of the tires; a resonance frequency assumption means for assuming a resonance frequency of the tires; and a determination means for detection of deflated tires using a decreased pressure determination index calculated by a relative comparison of the rotation speeds of the tires and the resonance frequency. The determination means is so configured as to reduce the second threshold to be compared with the decreased pressure determination index to a value equal to or higher than 1% and equal to or lower than 90% and to detect deflated tires when the decreased pressure determination index exceeds the reduced threshold.Type: GrantFiled: May 30, 2012Date of Patent: May 20, 2014Assignees: Sumitomo Rubber Industries, Ltd., Honda Motor Co., Ltd.Inventors: Yuji Oshiro, Seigou Sakagami, Masashi Kitano, Hiroaki Kawasaki, Tomonori Sakai, Shinya Notomi, Kazunari Okada

Patent number: 8582586Abstract: In an onboard gateway apparatus, when data is received from one network, the received data is stored in the buffer. The buffer includes a first storage area for storing data in the order of priority of an identifier (ID) attached to the data and a second storage area for storing data in the order in which the data is received. A control means stores the received data in one of the first and second storage areas based on the attached identifier, and sends the data to another network in accordance with the priority of the ID of the data. As to data passing through the first storage area, sending in the order of priority is ensured. As to data passing through the second storage area, sending in the order in which the data is received is ensured.Type: GrantFiled: April 1, 2010Date of Patent: November 12, 2013Assignees: Honda Motor Co., Ltd., Honda Elesys Co., Ltd.Inventors: Michitaka Tsuboi, Makoto Ikeda, Yoshiaki Murata, Kazuhisa Yamamoto, Kazuo Hirabayashi, Tetsuya Yashiki, Kazunari Okada, Shuji Tomimatsu, Hiroshi Nishimura

Publication number: 20070239334Abstract: A turning motion control system for a vehicle includes an actuator, and an actuator control device for controlling the actuator so that an actual turning motion state of the vehicle becomes close to a target turning motion state. The actuator control device is designed so that its control-permitted state and its control-stopped state can be switched from one to another through a switching device operated by a driver. When an air-pressure decreased state detecting device has detected an air-pressure decreased state, the actuator control device carries out the control of the operation of the actuator, irrespective of a switching mode of the switching device. Thus, even if an air-pressure decrease or an abnormality is generated in any of wheels in a state in which the turning motion control by the actuator has been stopped, the stability of the vehicle can be ensured.Type: ApplicationFiled: May 31, 2007Publication date: October 11, 2007Applicant: HONDA MOTOR CO., LTD.Inventors: Nobuyuki Imaizumi, Yoshihiro Iwagawa, Susumu Ohta, Kazunari Okada, Hironobu Kiryu, Kazuya Sakurai, Masakazu Shiraishi, Tomoaki Sugano, Toshio Yahagi
