Patent number: 9508257Abstract: An analyzer of the invention adequately analyzes a change in road network by using probe information generated with driving of a vehicle. This analyzer determines a traffic amount of vehicles passing through a specified section included in the road network from a plurality of the probe information accumulated over a predetermined period. The analyzer also determines a discontinuity rate, which is a rate of incidents that vehicle locations are discontinuous in the specified section, from the plurality of probe information accumulated over the predetermined period. The analyzer detects a change in the road network, based on a degree of change between traffic amounts in two different periods with respect to the specified section included in the road network and a degree of change between discontinuity rates in the two different periods. The detected change in the road network can be used for survey of the road network.Type: GrantFiled: February 7, 2014Date of Patent: November 29, 2016Assignees: ZENRIN CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Hiroyuki Tashiro, Kei Hiroo, Yoshitaka Nishino, Tomoki Kodan, Motohiro Nakamura, Sadahiro Koshiba, Kazuteru Maekawa

Patent number: 9469299Abstract: Deceleration control systems, methods, and programs acquire from learning information a target deceleration point in front of a traveling vehicle and an associated deceleration end point. The deceleration end point is a point representative of one or more locations at which deceleration of the vehicle or another vehicle was actually completed in the past as the vehicle or the other vehicle approached the associated deceleration end point. The systems, methods, and programs determine a distance between the acquired target deceleration point and the acquired deceleration end point as a predicted distance over which traffic is present. The systems, methods, and programs communicate with a vehicle ECU to perform a deceleration control of the vehicle so that (i) the longer the determined distance, the greater the deceleration rate applied during the deceleration control, and (ii) the deceleration is complete by the time the vehicle reaches the acquired deceleration end point.Type: GrantFiled: August 22, 2014Date of Patent: October 18, 2016Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toshiaki Niwa, Tomoki Kodan, Kuniaki Tanaka

Patent number: 9074902Abstract: When an update instruction to update “A” navigation map information and “B” navigation map information is inputted, a CPU initializes the storage area having stored therein no map information currently in use out of the two storage areas. The CPU then reads, from a CD-ROM, the latest version of the “A” navigation map information or the “B” navigation map information that corresponds to the map information currently in use, and stores it in the initialized storage area. The CPU then updates management information, starts use of the newly stored map information, initializes the storage area having stored therein the map information whose use is stopped out of the two storage areas, reads, from the CD-ROM, the latest version of the “A” navigation map information or the “B” navigation map information not currently in use, and stores it in the initialized storage area.Type: GrantFiled: February 9, 2010Date of Patent: July 7, 2015Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Hikaru Nagasaka, Hiroyoshi Masuda, Tetsuo Kumagai, Tomoki Kodan, Kazunori Watanabe, Yasutaka Atarashi, Takayuki Watanabe
