Abstract: 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.

Abstract: 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.

Abstract: A navigation apparatus reduces route search time while providing guidance in conformity with drivers' preferences, by selectively conducting either a full-range route search or a more limited, local area search, in accordance with detected conditions and responsive to occurrence of an off-route event. For example, the full-range route search is conducted pursuant to a determination that the vehicle has gone straight at a predetermined number of certain intersections where current guidance has directed a turn.

Abstract: A voice route-guidance system for vehicles which terminates its route-guidance when the vehicle arrives at the destination and even if the present position of the vehicle is measured with low accuracy. An approach judging unit judges that the vehicle approaches a point spaced apart from a destination by a predetermined distance. A guidance termination judging unit further judges whether or not there is a point in which the route-guidance should be carried out between the present vehicle position and the destination. From these judgments, the system judges that the vehicle approaches the point spaced apart from the destination by the predetermined distance and also that all the route-guidance has been terminated. Thus, a termination unit terminates the route-guidance.

Abstract: 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.

Abstract: A vehicle navigation system includes a simulated run mode along with a normal navigation mode. In the simulated run mode, a simulated present position is calculated to move in accordance with simulated motion so that route guidance information is presented to the viewer in the same manner as during actual navigation. The simulated motion may be increased or decreased, may be stepped or continuous, and/or may be controlled in accordance with stored speed information on the roads of the route.

Abstract: A navigation system for guiding a vehicle to a destination in accordance with a predetermined route composed of roads and branching points. A data base stores the names of the roads, the names of the branching points, and information relating entry roads to exit roads. A first picture display is a route information screen listing at least the road names and the branching point names, which screen may be called up by a screen operating signal issued from an input switch. A controller reads the route information from the data base in response to the screen operating signal from the input switch and forms the listing displayed on the route information screen.

Abstract: A position input system for a vehicular navigation apparatus includes an input unit for inputting a desired destination and a present position, a memory unit for storing desired destination information and map information, and a display unit for outputting the desired destination information and map information in response to input information from the input unit. The map information is indicative of intersections and a geographical point located between intersections and possessing useful guidance information. A desired destination and present position are capable of being inputted by setting the useful guidance information between a road leading to and a road leading from the geographical point. This makes it possible to enter position simply and accurately. Positions are precise since they are selected from pre-stored information relating to geographical locations. Vehicle direction can also be inputted in accurate fashion where parking lot exits and intersections are concerned.
