An on-board navigation apparatus in which coordinate data of formerly set designations are held in a memory, the destination coordinate data stored in the memory are read out at the time of destination setting, and one piece of destination coordinate data is selected from the read designation coordinate data in accordance with an operation input to thereby set a destination according to the selected one piece of destination coordinate data. The arrangement can allow a user to easily set the same destination as a formerly set destination only by a simple selecting operation.

In an information reproducing apparatus, when a car is travelling, it is inhibited that the image information played back by a DVD reproducing apparatus is displayed on a display device, or the map information outputted from a navigation system is displayed. Further, when the control information for the play back control is recorded in an information medium played back by the DVD reproducing apparatus, even when the car is travelling, the operation state of the DVD reproducing apparatus according to the control information is displayed on the display device by the superimposition display.

An on-vehicle navigation apparatus displays travel locus marks that permits a user to grasp the driving condition of a vehicle having this apparatus installed therein, while securing good visibility of the background map. The on-vehicle navigation apparatus has a storage means for storing a plurality of pieces of travel locus data in response to a predetermined collecting timing, and another storage means for storing an elapsed time from one predetermined collecting timing to the next predetermined collecting timing. The apparatus reads out the travel locus data and elapsed time .DELTA.ti respectively from those storage means, designates different travel locus marks in accordance with the read-out elapsed time .DELTA.ti, and shows the travel locus marks on a display screen on the basis of read-out travel locus data. A traffic jam index Ji and a specific value may be used in place of the elapsed time .DELTA.ti.

A navigation apparatus for a movable body is provided with: a measurement device for measuring a present position of the movable body; a setting device for setting route position information corresponding to a plurality of scheduled route positions which are scheduled to be passed on a route to a destination; a memory device for storing the present position at predetermined time intervals as passed position information between a start time, which is a time when the setting device starts to set the route position information, and an end time, which is a time when the setting device ends to set the route position information; a judgement device for judging whether or not the movable body has passed the scheduled route positions between the start time and the end time on the basis of the passed position information stored in the memory device, after the end time; and a guidance device for generating a message to guide the movable body from the measured present position to the destination on the basis of the scheduled route positions which the movable body has not passed yet according to a judgement result of the judgement device.
摘要:
An on-vehicle navigation apparatus in which destination coordinate data stored in a memory is erased when the distance from the present location to a destination is equal to or smaller than a predetermined value at the time the engine of a vehicle is started. The destination coordinate data will not therefore be erased while the vehicle is actually running toward the destination. The arrangement prevents display of navigation information such as the direction and distance from being stopped before the vehicle arrives at the destination.

A navigation apparatus having a GPS receiver obtain coordinates of the current position. A key point or points close to the current position are retrieved from a recording medium attached to the apparatus. The distance and direction from the current position with respect to the retrieved point are computed. The name of the retrieved point is then displayed along with the distance and direction with respect thereto.
摘要:
An onboard navigation system for displaying a map in a scrolling manner while a mark showing the position of the vehicle is fixed. The system is adapted so that the fixed display position of the mark indicating the vehicle's position can be set at an arbitrary selected position, satisfying a user's demand for viewing a map of an area further ahead of the vehicle in the direction of the vehicle's movement.
摘要:
An on-board navigation apparatus having a GPS receiver detects a difference between the current and the previous values of the estimated current position in terms of the longitude and latitude information gained from GPS data. The difference is added to the coordinates of the previously established position, the result being taken for the coordinates of the estimated current position. This makes it possible to estimate the current position coordinates accurately even if the accuracy of GPS data is not high enough. When the GPS receiver is in a two-dimensional measuring state, the coordinates of the estimated current position are obtained from a manually or automatically designated elevation value and from the GPS data. This allows the current position coordinates to be estimated with accuracy even if the accuracy of GPS data has dropped due to the two-dimensional measuring instead of a three-dimensional measuring.
