摘要： Geographical, guide or search information and route information are stored in storage sections 10 and 24. In order that an arithmetic section 20 may realize a route re-searching function in preference to the traveling direction of a vehicle, a route-calculating section 22 is equipped with a re-calculation section 22c for re-calculating the route, and a route guide control system 26 is equipped with a route deviation-detecting section 26b. The re-calculating section 22 calculates either the shortest route from the point of deviation to the previous route or a new route to the destination. In case of the search of the shortest route to the previous route, the shortest route from the present location to the previous route is searched in preference to the traveling direction (with no U-turn) on the basis of the search information of the periphery of the present location, so that the route to joint to the previous one can be quickly calculated. In case of search of a new route, the whole route from the present location to the destination is searched in preference to the traveling direction on the basis of the search information between the present location and the destination, to guide the driver along a route other than the previous one.

摘要： A road map display device including a road map information memory for memorizing road map data on a two-dimensional coordinate and a detection device for detecting a present position and a travel direction of an automotive vehicle, wherein the two-dimensional coordinate of the road map data is read out from the information memory in accordance with the present position and travel direction of the vehicle detected by the detection device and displayed in the form of a plane view on a screen of a display unit. In the road map display device, trapezoid conversion parameters are determined on a basis of a conversion formula for converting the two-dimensional coordinate of the road map to a trapezoid coordinate for display of a perspective view in such a manner that an upper side of a square two-dimensional coordinate is contracted relatively to a lower side of the two-dimensional coordinate, and the road map data included in a reverse trapezoid coordinate defined by a reverse conversion formula of the conversion formula are read out from the road map information memory and introduced into a trapezoid coordinate defined by the trapezoid conversion parameters such that the road map data are displayed in the form of a perspective view on the screen of the display unit.

摘要： A route guidance system for vehicles is adapted to carry out route guidance based on stored data relating to a route from a start position to a destination. The route guidance is based on a detected present position of the vehicle and on the stored data relating to the route to the destination. The distance between the present position of the vehicle and the destination is detected and if the distance is not greater than a predetermined value it is judged that the vehicle is approaching the destination. The route guidance is terminated in response to the distance not greater than the predetermined value, and the route guidance is again started after being terminated responsive to an instruction from a restart directing means if it is not detected that a distance between the present position of the vehicle and the destination is not greater than the predetermined value.

摘要： In a navigation apparatus for a vehicle, after the present position of a vehicle is obtained, a position on a map which corresponds to the present position of the vehicle is obtained. Subsequently, the heading direction of the vehicle is detected. When the vehicle is traveling on the left-hand lane, coordinate conversion is performed such that a present position mark is shifted leftward from the center of the road by 1/4 of the road width. This makes it possible to display a route while preventing the route from overlapping with the centerline of the road. In another navigation apparatus for a vehicle, a structure-profiled map on which a structure-representing shape and a road are drawn is displayed so as to provide road guidance, wherein a route is displayed on the structure-profiled map along a road which is displayed for guidance. The display of the route is performed such that the route is shifted from the center line of a road toward a lane on which the vehicle is traveling. The route is displayed by using a pattern having a width corresponding to the width of the road in accordance with the lane of the road to be guided.

摘要： A navigation system provides road guidance by displaying information relating to roads on a structure shape map, together with landmark information, in such a manner that only information around the present position is highlighted. The system retrieves road information in the direction of travel from the present position according to the vehicle speed, or road information within a predetermined angular or distance range in the direction of travel. Information relating to roads includes information indicating a one-way road, information indicating a road into which entry is prohibited, and information indicating a pedestrian crossing and a railroad crossing. These items of information are displayed by using marks, and the landmark information is displayed by using landmarks, thereby displaying information necessary for travel in a readily perceivable manner according to the travel conditions. When the vehicle enters a parking lot in the middle of the guidance for a route to a destination, the system searches for a route from the parking lot to the destination and outputs the found route by using a structure-shape map. The parking lot in this case is one within a predetermined walking distance from the destination. If the parking lot is in close proximity of the destination, further guidance is not necessary and the guidance is terminated.

摘要： An apparatus to facilitate volume control for route aural guidance. When supplying a guidance voice to a loudspeaker 34a, a voice control section 30 disconnects the loudspeaker 34a from audio and outputs the guidance voice through the loudspeaker. A volume control screen is displayed on a display section 28 where the user adjusts the volume by touching the screen. When the voice control section 30 switches a signal to the loudspeaker 34a, a mute circuit 40a is operated to mute the voice output before the voice is output through the loudspeaker 34a. When the user terminates volume adjustment, the voice control section 30 outputs a voice for volume confirmation or check at the adjusted volume through the loudspeaker 34a. The user can check the adjusted volume at this time.
