Patent number: 8364391Abstract: A navigation system includes an information center and a navigation device installed in a probe vehicle. The information center stores limiting information for specifying a content of probe information in accordance with predefined factors, specifies a predefined factor corresponding to a navigation device, selects the limiting information based on the specified predefined factor, transmits the selected limiting information to the navigation device, and receives the corresponding probe information transmitted from a navigation device. The navigation device receives the limiting information from the information center, collects probe information, selects only the probe information specified by the received limiting information for transmission to the information center, and transmits the selected probe information to the information center.Type: GrantFiled: October 3, 2007Date of Patent: January 29, 2013Assignee: Aisin AW Co., Ltd.Inventors: Kenji Nagase, Hiroki Ishikawa, Hiroshi Tomita, Takayasu Nakada

Patent number: 8150612Abstract: In a case where a CPU provided in an information distribution center has received, from a navigation apparatus, vehicle information together with a request command for requesting traffic information such as current traffic information, the CPU sets a road category that serves as a distribution target of the traffic information, based on one of a distance and a required travel time from a vehicle position to a destination. The CPU then extracts the traffic information that corresponds to the set road category and distributes it to the navigation apparatus.Type: GrantFiled: September 27, 2007Date of Patent: April 3, 2012Assignee: Aisin Aw Co., Ltd.Inventors: Kenji Nagase, Hiroki Ishikawa, Takayasu Nakada

Patent number: 8103437Abstract: In a case where a CPU 11 provided in an information distribution center 3 has received a request command for requesting predicted traffic information transmitted from a navigation apparatus 2 as well as vehicle information such as a navigator identifying ID, coordinate data of a vehicle position, or coordinate data of a destination, the CPU 11 searches a basic route based on update-purpose map information 14A, and sets a distribution range serving as a transmission target of traffic information 16A, 16B, and 16C. Then, the CPU 11 generates the predicted traffic information 16C such as congestion prediction information corresponding to the distribution range, extracts the predicted traffic information 16C of each link having a difference in the generated predicted traffic information 16C and the current traffic information 16A, and distributes the extracted predicted traffic information 16C to the navigation apparatus 2 together with a link ID of a corresponding link.Type: GrantFiled: October 15, 2007Date of Patent: January 24, 2012Assignees: Aisin Aw Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Kenji Nagase, Takayasu Nakada, Kazutaka Yoshikawa, Toshio Inoguchi

Patent number: 8060300Abstract: Systems, methods, and programs, store map data including a roadway network, detect a current position of the vehicle, and detect or receive at lest one of a distance to another vehicle, a speed of another vehicle, and traffic congestion information. The systems, methods, and programs determine whether the vehicle is within a predetermined distance of a passing lane, a climbing lane, or a lane for slower traffic based on the detected current vehicle position and the map data. If the vehicle is within the predetermined distance, the systems, methods, and programs provide guidance regarding the passing lane, the climbing lane, or the lane for slower traffic based on at least one of the distance to the other vehicle, the speed of the other vehicle, and/or the received traffic congestion information.Type: GrantFiled: March 9, 2007Date of Patent: November 15, 2011Assignee: Aisin AW Co., Ltd.Inventors: Kenji Nagase, Hiroshi Tomita, Toshiaki Minami, Takayasu Nakada
