摘要： There is disclosed an apparatus for displaying a current location of a running body in which a constantly changing location of the running body on a two-dimensional coordinates is successively computed, while detecting a running distance of the running body and a running direction of the same, and the current location of said running body is displayed renewally, in accordance with the data thus computed, on a display screen having a map previously displayed thereon. The apparatus comprises means for extracting a linear running portion from current location of the running body obtained by storing data of the current location, means for extracting a linear road portion from adjoining roads on the map which corresponds to the linear running portion extracted from the current location means for effecting matching between the extracted linear running portion and linear road portion, depending on their positional relationship and means for putting the current location, onto the road to which the matching has been effected.

摘要： Disclosed is a travel path displaying apparatus for indicating the current position of an automobile running on a selected road in a road map appearing on an associated screen. A cumulation of errors in estimating sequential current positions will cause an incorrect indication of the automobile's position on the screen and the automobile will depart from all the roads appearing on the screen. In order to find the correct road on which the automobile is traveling it is necessary to carry out pattern matching between the travel trace and each of a number of selected roads, thereby determining which road is closest to the travel trace in shape. The apparatus permits selection of the least possible number of roads for pattern matching, thus permitting quick determination as to the road on which the automobile is traveling and as to the direction in which it is traveling.

摘要： There is disclosed an apparatus for displaying a travel path of a running body in which a constantly changing location of the running body on a two-dimensional coordinates is successively computed and the current location of said running body is displayed successively, in accordance with the data thus computed, on a display screen having a map previously displayed thereon. According to this apparatus, longitude and latitude values of a reference point in a mesh consisting of lines of longitude and latitude in each map of divided areas are registered as known factors and the current location of the running body on the two-dimensional coordinates thus computed is converted to a location on longitude-latitude coordinates, whereby the current location on the map is calculated from the known longitude and latitude values of the reference point displayed on the display screen.

摘要： An apparatus for displaying a travel path of a running body in which a direction detector includes a geomagnetism sensor as well as a rate-type sensor, such as a gyroscope or gas rate sensor (which includes a flow sensor for detecting a degree of displacement of a gas flow produced by an angular velocity applied thereto) for detecting an angular volocity of change of yawing direction of the moving body, in which a difference in angle between directions detected by the rate-type sensor and the geomagnetism sensor is found and temporarily stored when a power source is temporarily turned OFF during operation of the running path displaying apparatus, and then a declination of the direction detected by the geomagnetism sensor is corrected, depending upon the stored difference in angle, when the power source is turned ON again.
