Patent number: 7623947Abstract: An abnormality determining apparatus is applied to a vehicle motion control apparatus in which a vehicle behavior sensor (yaw rate sensor, etc.) is integrally mounted to an integrated unit that is integrally composed of an HU (hydraulic unit) and ECU. In this abnormality determining apparatus, the pattern of the vibration noise appearing on the output from the vehicle behavior sensor (output from yaw rate sensor Yrfilpc, etc.) is obtained when various actuators such as motor, solenoid valves, or the like, that are mounted to the HU, are operated with a predetermined pattern for a primary check for the HU. When the pattern of the vibration noise is not within the predetermined normal pattern range, it is determined, according to the abnormal manner of the pattern of the vibration noise, that the abnormality of the vehicle behavior sensor, abnormal operation of the actuator in the HU, or the like occurs.Type: GrantFiled: November 9, 2006Date of Patent: November 24, 2009Assignee: Advics Co., Ltd.Inventors: Hitoshi Hashiba, Kazunori Sakai

Patent number: 6879563Abstract: A multiplex communication system having a data repeater, which can prevent data from being lost so as to improve reliability of data communication, when a data repeater of a multiplex communication system repeats data. A multiplex communication system is made up of a plurality of communication groups including a plurality of communication lines and a data repeater. The data repeater is made up of receiving buffers, sending buffers, a data controller and a transfer-address table. The data controller selects multiplex communication lines through which the received data is to be repeated and transfers the received data thereto. The data controller has a priority-reset means for increasing a priority of a received data before being sent. The priority-reset means prioritizes a sending of the data from the data repeater, even if the data sent from the data repeater collides with the other data on the multiplex communication lines through which the received data is to be repeated.Type: GrantFiled: February 17, 2000Date of Patent: April 12, 2005Assignees: Nippon Soken, Inc., Denso Corporation, Toyota Jidosha Kabushiki KaishaInventors: Kenji Tomita, Ikuo Hayashi, Yoshihisa Sato, Toshihiro Wakamatsu, Tomohisa Kishigami, Kazunori Sakai, Masachika Kamiya, Hiroshi Honda, Masato Kume, Mikito Yagyu

Patent number: 6127947Abstract: A vehicle onboard device having characteristics capable of being changed communicates with a vehicle to set a characteristic value to an optimum value. Parameters for setting conditions of an electronic device are called out of an E.sup.2 PROM 14.sub.i of the vehicle 10.sub.i and are transmitted to a technology center 40 via a dealer 20.sub.1, and an information center 30.sub.1. Each dealer 20.sub.1, the information center 30.sub.1, and the technology center 40 accumulate the parameters. The technology center 40 can collect the parameters of numerous vehicles and characteristic values for electronic control of each of the vehicles and can calculate newest and optimum parameters. The technology center 40 transmits this newest and optimum vehicle information to the vehicle 10.sub.i, and each vehicle updates the parameters thereof to these newest and optimum parameters. Accordingly, the parameters of the vehicle are set as the newest parameters.Type: GrantFiled: July 12, 1999Date of Patent: October 3, 2000Assignee: Toyota Jidosha Kabushiki KaisaInventors: Toshihiro Uchida, Hiroshi Honda, Akihiro Tanaka, Kazunori Sakai, Norimasa Hiramatsu
