示す通過表示ランプ3を点滅させる。 Further, FIG. 4 shows a configuration for realizing the present invention based on the above principle. This will be discussed next. In the figure, 11 is a vehicle speedometer, 12 is a geomagnetic vector detector, 13 is a coordinate input keyboard, and 14 is a
15 is a calculation processing circuit, 15 is a direction change detection circuit of 80° or more, 16 is a measurement position coordinate memory, 17 is a passage judgment comparison circuit, 18 is an approach judgment comparison circuit, 19 is a set coordinate memory, 20 is magnetic north detection, target direction comparison 21 is a magnetic north display target location display section, 2 is a passage display circuit, and 23 is an approach display circuit. Vehicle speedometer 1
1 to the geomagnetic vector detector 12.
The azimuth and angle signals are respectively extracted from the azimuth angle signals, and the arithmetic processing circuit 14 calculates the position coordinates (X i Y i ) of the vehicle. The position coordinates of the car are stored in the measured position coordinate memory 16 every moment from the origin (00). On the other hand, multiple target location coordinates (including intersection coordinates (X 0 Y 0 )) are
The coordinates are input in advance from the coordinate input keyboard 13 and stored in the measurement coordinate memory 19. The intersection coordinates (X 0 Y 0 ) of one of the target locations and the previously measured position coordinates (X i Y i ) are compared by the approach determination comparison circuit 18 . The car starts from the starting location coordinates (00),
Approaching the intersection, the straight line distance R i (=
When √(X i −X 0 ) 2 + (Y i −Y 0 ) 2 ) satisfies the condition of d<R i <2d, that is, when it reaches the first predetermined value 2d,
An approach determination signal, which is a first signal, is output from the approach determination comparison circuit 18 to the approach display circuit 23, causing the passage display lamp 3 shown in FIG. 1 to blink.

る。 When the vehicle further approaches the intersection and satisfies the condition R i <d, that is, when the second predetermined value is reached, the passage determination comparison circuit 17 outputs a second signal, a passage determination signal, to the passage display circuit 22. The passage indicator lamp 3 lights up. The above approach judgment and passing judgment are at intersections,
This is carried out only in the direction approaching a predetermined value such as a target location.

み,動作する。 While the passing indicator lamp 3 is on, when a vehicle on the path 10 turns right or left at the intersection 9 as shown in FIG. The data of the measured position coordinates at that time are transferred to the memory 16 and replaced with preset intersection coordinates (X 0 Y 0 ) to perform automatic calibration of the position coordinates. By this means, any accumulated errors that may have existed to some extent are eliminated. In the above case, the 80° or more azimuth change detection circuit 15 operates only at points where the intersection coordinates, etc. have been input into the set coordinate memory 19 in advance.

斜線部分のように点灯する。 In addition, the magnetic north detection and target location comparison circuit 20 receives the measured position coordinate data from the measured position coordinate memory 16, calculates the direction of magnetic north with respect to the direction of travel of the vehicle, and simultaneously stores the measured position coordinate data and the set coordinate memory 19. By comparing the target location coordinates (X p Y p ) with the target location coordinates (X p Y p ), the direction of the destination location relative to the direction of travel of the vehicle is calculated. The calculated magnetic north direction and target location direction are displayed on the magnetic north marker and target location display section 21, respectively.
and turn on the indicator lamps for each direction as shown in the shaded areas in Figure 1.
以上構成に関し述べたが第3図に示す交差点で

よい。 That is, a signal source of the induced magnetic field may be installed at the intersection, and the coordinates may be switched when the vehicle detects the induced magnetic field. Alternatively, the coordinates may be calibrated by visually observing that the vehicle has come to an intersection and manually pressing a switch for replacing the coordinates at that point.
