摘要： According to the invention, when a target name is inputted using characters such as alphabet and numerics, strings of characters or numerics are compared with data of registered places each time one character is inputted, names of registered places including the inputted string of characters or numerics is listed, and the number of registered target names remaining on the list is displayed. When the target name is inputted in characters, the inputted data is compared with a list of the registered names having word components arranged in different orders with respect to a single official name by a forward match comparison, and the number of registered target names remaining on the list with forward match is displayed. When the number of the inputted characters or numerics increases and the number of registered target names remaining on the list decreases, a list of the registered place names is displayed. The target name is selected from this list. When the number registered target names remaining on the list is one, the target name is selected. A map of the vicinity of the target name thus selected is displayed.

摘要： A goal direction mark and a distance to a goal are indicated when the car has approached the end point of route. When the car has deviated from the guide route to the goal or is running backwards on the guide route, there is indicated a mark to inform the direction of progress to the goal on the guide route. When the car has deviated from the guide route and the guide route is not indicated on the map picture, there is indicated the direction to the goal or the direction to the guide route itself. When the start point of route is remote from the present position at the start of the guidance, a mark is indicated to inform the direction to the start point of route. The driver is enabled to easily determine relying upon the indicated mark in which direction he should proceed. When the map picture is scrolled, there is informed the goal direction, route direction or the direction of progress to the goal on the route. The user therefore is enabled to easily know the direction to the goal.

摘要： Navigation data (26) are generated by performing course exploration up to a destination using path data (26), which include information relating to intersections and road information, in response to input of the destination. Course guidance to the destination is provided while present-position pursuit (37) is performed. Course guidance at an end-point of a present-position road is outputted using guidance information for travel to a destination at every intersection obtained from the road network data (26) by course exploration. At an intersection, a road in a direction of travel is recognized by the present-position pursuit means (37), present position on this road is kept track of and the end-point intersection of the road is recognized. Recognition of the travelling direction is performed at the end-point intersection of a road between intersections, and guidance to the next end-point intersection is outputted with the road in the travelling direction serving as a present-position road, whereby course guidance is performed repeatedly at every intersection up to the destination. In course exploration, a road in the direction of travel leading to the destination is set with regard to each intersection. Therefore, if an intersection and the road in the travelling direction thereof are recognized, it is possible to provide course guidance from the end-point intersection of the road in the travelling direction to the destination.

摘要： In a navigation system, during navigation between guidance intersections A and B, a next named intersection C is displayed along with the distance remaining until the named intersection B is reached. After the vehicle has entered the distance error correction range, illumination color of the display of the next named intersection C is changed into, for example, red. If a corresponding portion of the display screen is touched at the time of passage though the intersection, a distance error is corrected. The invention thus makes it possible to readily correct distance errors with accuracy. Even during navigation along a straight road, distance correction can be performed at specific intersections. The invention also makes it possible to track the present position with accuracy by increasing the frequency of distance error correction.

摘要： A navigation apparatus for navigating an automotive vehicle in accordance with a preset course while measuring distance travelled and steering angle is characterized by previously storing positions of charactering features along the course and guidance information relating to said characterizing features, correlating travelling distance and the positions of the characterizing features, and outputting guidance information relating to a particular characterizing feature on the condition that said characterizing feature has been approached. Guidance information relating to a particular characterizing feature is outputted when the vehicle has approached this characterizing feature. Thereof, by matching this guidance information with the circumstances along the course, the driver can verify during travel whether the course is correct or not. Accordingly, even if it is a long distance to the intersection at which the next turn is to be made, the driver is capable of verifying the course by the time this intersection is reached. this enables the driver to drive the vehicle without anxiety.
摘要翻译：用于在测量行驶距离和转向角度的同时根据预设路线导航机动车辆的导航装置的特征在于，预先存储沿着路线的特征特征的位置和与所述特征特征相关的引导信息，将行驶距离和位置相关联表征特征，并且在已经接近所述特征特征的条件下输出与特定特征特征相关的引导信息。当车辆接近该特征特征时，输出与特定特征特征相关的指导信息。因此，通过将此指导信息与课程的情况进行匹配，司机可以在旅途中验证课程是否正确。因此，即使与要进行下一回合的交叉路口距离很远，驾驶员也能够在到达该交点的时刻验证路线。这使驾驶员无需焦虑地驾驶车辆。

摘要： A navigation apparatus for navigating a vehicle in accordance with a preset course while measuring distance travelled and steering angle has voice track indication means in which voice track indications corresponding to the distance remaining to an intersection at which the next turn is to be made are outputted as the intersection is approached. When the distance from this intersection to the next intersection requiring a turn is less than a predetermined value, a voice track indication pointing out a lane into which the vehicle should be steered following the turn at the former intersection is outputted after the final voice track indication given just before the vehicle reaches this intersection. When it is required that a turn be made at the latter intersection immediately after the turn at the former intersection, the lane information for the turn at the latter intersection is outputted before the vehicle is turned at the former intersection. This makes it possible for the driver to steer the vehicle to the lane appropriate for the turn at the latter intersection while the vehicle is being turned at the former. Accordingly, in situations where it is required to make the turn at the latter intersection immediately after effecting the turn at the former, the driver can make the proper maneuvers smoothly and without haste.
