Patent number: 8725404Abstract: This invention relates to a method for updating digital maps and for matching global navigation devices to a digital map. Such navigation devices rely upon GPS signals (20, 24) from satellites (22, 26). One well-documented cause of position error in navigation devices arises from the phenomenon of GPS multi-path. It has been observed that GPS multi-path errors in the latitude/longitude direction are highly correlated with errors in altitude. By comparing altitude value of GPS probe data with reference specifications for altitude, unreliable probe data (outliers) can be easily identified and culled. Such techniques can be used as well by a mobile navigation device to confirm a match to a particular road segment and if not revert to other positioning techniques such as inertial guidance systems and the like. If the local altitude is not reliably known, an estimation can be derived directly from the collected probe data.Type: GrantFiled: December 31, 2009Date of Patent: May 13, 2014Assignee: TomTom Polska Sp. z o.o.Inventors: Marcin Michal Kmiecik, Wojciech Tomasz Nowak

Publication number: 20130304374Abstract: An apparatus for recognizing a position of a moving object includes a sensor information collector to collect sensor information associated with movement of the moving object, a camera to capture a front image based on the movement of the moving object, and a GPS receiver configured to receive a GPS position of the moving object. Further, the apparatus includes a location recognizer to display N number of particles, each of which indicates a candidate position of the moving object, in a certain region about a GPS location of the moving object on a map. The location recognizer then updates a location of the particles based on the movement of the moving object, and progressively reduces number of particles on the basis of accuracy of the position-updated particles, thereby recognizing the position of the moving object.Type: ApplicationFiled: December 12, 2012Publication date: November 14, 2013Applicant: Electronics And Telecommunications Research InstituteInventor: Electronics And Telecommunications Research Institute

Publication number: 20130261921Abstract: A driving support device includes a maximum measurement range determination unit adapted to calculate a distance to a plurality of points on a surface of an object present at surroundings of a vehicle. A distance sensor such as a laser range finder or a stereo camera that measures a distance is used in order to estimate bias of an acceleration sensor with high accuracy upon correction of the bias by use of the distance sensor such as the stereo camera or the LRF in a GPS non-receiving section. A sensor parameter estimation unit is adapted to estimate a parameter of the acceleration sensor based on a behavior of an own vehicle obtained from a vehicle translation and rotation angle calculation means adapted to count backwards the vehicle behavior based on distance variation and also based on a measurement value of the acceleration sensor.Type: ApplicationFiled: December 6, 2011Publication date: October 3, 2013Applicant: Hitachi, Ltd.Inventors: Mikio Bando, Yukihiro Kawamata, Toshiyuki Aoki

Patent number: 8547211Abstract: A route retrieval apparatus is disclosed. The route retrieval apparatus includes a storage component, a first correction component, a second correction component and a retrieval component. The storage component stores therein probe information to specify fuel consumption in each section, the probe information having been collected from probe vehicles. The first correction component corrects gradient information of each section based on the specified fuel consumption in the each section. The second correction component corrects a fuel cost of each section based on the gradient information corrected by the first correction component. The retrieval component retrieves, by using the fuel cost of the each section corrected by the second correction component, a route with a lowest total of the fuel costs from a departure point to a destination point.Type: GrantFiled: May 10, 2011Date of Patent: October 1, 2013Assignee: Denso CorporationInventor: Masahiro Miyoshi
