Since a point list that displays the travel order of the via points in a recognizable manner is created and displayed, it can be used for driving plans and the like. In addition, when one of the waypoints included in the point list is selected by the selection means, the set route is changed from a plurality of waypoints to a route in which the one waypoint is deleted, so the route is displayed while displaying the point list. Can be easily changed.

  Hereinafter, embodiments of the present application will be described with reference to the drawings. In FIG. 2, the block diagram of the vehicle-mounted navigation apparatus of one Example of this application is shown. As shown in the figure, the in-vehicle navigation device detects a geomagnetic sensor 1 that is an azimuth detecting unit that outputs absolute azimuth angle data of a vehicle based on geomagnetism (earth magnetic field), and an angular velocity that accompanies a change in the direction of the vehicle. A gyro 2 that is an angular velocity sensor that outputs angular velocity data, and a mileage sensor 3 that detects whether the vehicle is moving or stopped, outputs the state, and outputs vehicle traveling speed and moving distance data. A GPS positioning device 4 that receives radio waves from a plurality of GPS satellites, performs calculations, generates and outputs data such as latitude, longitude, altitude, and traveling direction, and a system that performs various processes such as calculation and control The controller 5 includes an input device 14 for inputting instructions to the system controller 5 and a display 15 such as liquid crystal or CRT.

  The system controller 5 includes an interface 6 that inputs the outputs of the geomagnetic sensor 1, the gyro 2, the mileage sensor 3, and the GPS positioning device 4 and performs A / D conversion and the like, and a CPU (Central Processing Unit) 7, ROM (Read Only Memory) 8 in which various processing programs and other necessary information are written in advance, and RAM (Random Access Memory) in which information necessary for executing the program is written and read. ) 9, image information that is composed of a CD-ROM, IC card, etc., on which digitized map information is recorded, and V-RAM (video RAM), etc. Map information sent in response to a command from the CPU 7 and a buffer memory 11 which is a frame buffer temporarily storing The graphic controller 12 for drawing the graphic data in the buffer memory 11 and outputting the drawing data as image information, and the display control circuit for controlling the image display of the display 12 by inputting the image information output from the graphic controller 12 13.

  In the navigation device configured as described above, when the system controller 5 is activated, it performs the following control as the current position display means. First, information for accessing map display information and the like, display information of the vehicle position mark, and the like are read from the recording medium 10 and stored in the RAM 9. Next, the latitude / longitude data as the vehicle position information and the traveling direction data of the vehicle are read from the GPS positioning device 4, the map data corresponding to the vehicle position is read from the recording medium 10, and sent to the graphic controller 12. Is displayed on the display 15. Further, a process for displaying the vehicle position mark on the map from the vehicle position information and the traveling direction is performed, and then the vehicle position information and the traveling direction data are periodically read from the GPS positioning device 4, and the vehicle is determined based on the information. Update processing of the display position and direction of the position mark and the map to be displayed if necessary. Further, the output data of the geomagnetic sensor 1, the gyro 2, and the mileage sensor 3 are periodically read, and the vehicle position and the traveling direction are calculated from the output data, and the calculated data and the GPS positioning are calculated. The data from the device 4 is compared with each other and the error is adjusted to perform correction processing.

  Further, the navigation device of this embodiment has a route guidance display function. In this route guidance display processing, the system controller 5 first receives a route setting input in the same manner as in the past by an instruction input. In this reception, first, a departure point and a destination point are received, then route points that are route points are sequentially received in the order of travel schedule, and route information including position information of longitude and latitude of each point and information indicating the travel order is stored in the RAM 9. To remember. Then, in traveling from the departure point, route guidance display is performed in which route points set in the same manner as in the past are sequentially set as target points, the direction, distance, and the like are calculated and target point information is sequentially displayed.

  Furthermore, in this embodiment, in this route guidance display function, a route setting state display for displaying the route setting state by a deformed diagram and a route change function for changing, deleting, adding, etc., the set point are added. Hereinafter, route setting state display processing and route change processing will be described.

FIG. 3 shows a process flowchart of the system controller 5 in the route setting state display, and FIG. 4 shows an explanatory diagram thereof. In FIG.
X_MIN: Deformation diagram drawing area X direction minimum value X_MAX: Deformation diagram drawing area X direction maximum value Y_MIN: Deformation diagram drawing area Y direction minimum value Y_MAX: Deformation drawing area Y direction maximum value DSP_X: Deformation drawing area X direction width DSP_Y: the width in the Y direction of the deformation diagram drawing area.

  The route setting state display process will be described with reference to the process flowchart of FIG. When the route setting state display is instructed and inputted, the system controller 5 first sets the minimum longitude (LON_MIN) and maximum from the set route point, destination, starting point, and current position of the vehicle. Longitude (LON_MAX), minimum latitude (LAT_MIN), and maximum latitude (LAT_MAX) are obtained (steps S1 to S4). Next, the scale factor SCL_X in the X direction and the scale factor SCL_Y in the Y direction in the display are obtained by the following equations (steps S5 and S6).

SCL_X = DSP_X / (LON_MAX-LON_MIN)
SCL_Y = DSP_Y / (LAT_MAX-LAT_MIN)
Further, the calculated scale factors in the X direction and the Y direction are compared, and the larger one is determined as the scale factor SCALE (steps S7 to S9).

  Then, the display coordinates (X, Y) of each of the route point, the destination, the departure point, and the current position of the own vehicle are obtained by the following equation (step S10).

X = (X_MIN + X_MAX) / 2 + SCALE × (LON_ROT
-(LON_MIN + LON_MAX) / 2)
Y = (Y_MIN + Y_MAX) / 2 + SCALE × (LAT_ROT
-(LAT_MIN + LAT_MAX) / 2)
Here, LON_ROT and LAT_ROT are the longitude and latitude of the drawing target point (route point, destination, starting point, current position). Based on the display coordinates thus obtained, a deformed map of the route point, the destination, the starting point, and the current position of the host vehicle is drawn (step S11).

  As shown in FIG. 4, in the drawing of the deformed map DEF, the route point has the numbers “(1),..., (4)” indicating the input order (running order), and the destination has the letter “eye”. The departure point is displayed as “Out”, the current position of the vehicle is displayed as “O”, and the dotted line connecting the points is displayed in the order of travel. Furthermore, “→” indicating the direction of the target point from the current position of the host vehicle is displayed. In addition, a list LIST indicating a starting point, a route point, and a destination for selecting a route change described later is displayed on the left side of the deformed map DEF. In the description in the present specification, the numerals with circles in FIGS. 1, 4 and 6 are changed to “(1)”, “(2)”, “(3)”, “(4)” and “ (5) ".

  Next, route change processing will be described. The route change process is performed by inputting a route point setting (addition) or deletion instruction in a state where the above-described deformation diagram is displayed. When there is a route point setting instruction input, the system controller 5 monitors the cursor movement instruction input, changes the selected cursor position in the list LIST by the input, and waits for an instruction input of an additional point position. The additional point is the next point after the point indicated by the cursor. For example, if (1) is selected in FIG. 4, new route points are inserted between the points (1) and (2), and the number of route points is 5. When there is an input of an additional point position instruction, the input of the set point is prompted next. The setting point is input depending on whether a map is displayed and an instruction is input, or position information on latitude and longitude is directly input. When there is an input of a new set place, the position information is inserted and stored in the corresponding order in the route information stored in the RAM 9. When this new setting location is input, the route setting state display process shown in FIG. 3 is performed to display again the changed route setting state. For example, in FIG. 4, if a new set place is input at the position “ON” between route points (1) and (2), an additional new route point is inserted as shown in FIG. Then, the changed route points (1) to (5) are displayed. Similarly, regarding the deletion, the storage information of the route point selected from the list LIST is deleted, and thereafter, the route setting state display process is performed, and the deleted and changed route setting state is displayed again.

  Next, target point change processing by newly setting or deleting a route point will be described with reference to the flowchart shown in FIG. First, when setting a route point, if it is a new setting, or if it is not a new setting but a new route point is set at a position before the target point, the new route point is changed to the target point and a new setting is made. If, instead, the new route point is set at a position behind the target point, the process ends without changing (steps S21 to S24). For example, in FIG. 4, when the current position of the vehicle passes the route point (1) and the target point is the route point (2), a new setting is made between the route points (1) and (2). Assuming that the ground is input at the position “ON”, as shown in FIG. 6, the new route point that has been added is inserted as (2), and the changed route points (1) to (5) are displayed. Since the new route point is set before the target point, “→” is displayed with the target point as the new route point (2). Also, in the case of deletion, when the route point that is the target point is deleted, if there is a next route point, the next route point is changed to the target point, and if there is no next route point If the previous route point is changed to the target point, and the route point that is the target point is not deleted, the target point is not changed and the processing ends (steps S21, S25 to S28).

  As described above, in the present embodiment, in the route guidance display, each point in the route from the departure point including the route point set and input to the destination point is arranged according to the actual position information and the route order can be understood. The displayed deformation diagram is displayed. As a result, for example, when using a delivery business that travels at multiple delivery points, the overall process of the day can be understood at a glance, and the distance between each point can be relatively roughly grasped. Useful. Further, when the host vehicle is traveling in the set route, the current position of the host vehicle is displayed in the deformed map corresponding to the actual position, and at the same time, the route point of the target point is indicated. As a result, it is possible to relatively grasp the current position in the entire process, or the distance to the local point and the remaining distance, which is useful for time management of the operation. Also, route points can be easily added and deleted, and the target point change display is automatically displayed, which is convenient when changing the route while traveling.

  In addition, in the display of the deformed diagram of the above embodiment, the display indicating each point is not limited to this, and the starting point, the destination, the route point, and the vehicle position can be identified, and the order of the route points can be understood. Should be displayed as follows. Further, the target point may be displayed not by an arrow from the vehicle position, but by a display in which the route point of the target point can be identified by color-coded display or blinking display, for example. Further, in selecting the position of the route point to be added or deleted, the route point in the deformed diagram may be designated and selected by the cursor instead of the selection by displaying the list.

  As described above, according to the in-vehicle navigation device of the present embodiment, when a departure point, a destination point, and a route point are set and inputted, and a route from the departure point to the destination point is set via the way point. Since a list composed of departure points, waypoints and destination points included in the set route is created and displayed, it can be useful for operation planning, etc., and from the displayed list, the list By selecting means for selecting one of the points included in the route, it is possible to easily change the route while displaying the list.

  Furthermore, according to the vehicle-mounted navigation device of the present embodiment, it is possible to easily select a point to be deleted from the route or select an additional position of a new point to be added to the route.
