[0039]
FIG. 3 is a diagram illustrating a hardware configuration example of the arithmetic processing unit (1).
Hereinafter, each component will be described.
[0040]
The arithmetic processing unit (1) has a configuration in which devices described later are connected by a bus. The arithmetic processing unit (1) includes a CPU (301) for performing various processes such as numerical calculation and controlling each device, a RAM (302) for temporarily storing maps and arithmetic data, and a ROM for storing programs and data. (303), DMA (Direct Memory Access) (304) for executing data transfer between the memories at high speed and between the memory and each device, a drawing controller (305) for controlling writing to the frame memory (306), vector A frame memory (306) for storing graphics image data in which data is developed into pixel information, a color palette (307) for converting image data into RGB signals, an A / D converter (308) for converting analog signals into digital signals, SCI (309) for converting serial signals into parallel signals synchronized with the bus, Composed counter (311) for integrating the the signal and synchronization is taken PIO to put on the bus (310), and a pulse signal.
[0041]
FIG. 4 is a diagram illustrating an example of a functional configuration of the arithmetic processing unit (1). Hereinafter, each component will be described.
[0042]
The current position calculation unit (406) uses distance data and angular velocity data obtained as a result of integrating the distance pulse data S7 measured by the wheel speed sensor (8) and the angular velocity data S9 measured by the gyro (10). Then, by integrating the data on the time axis, a process of calculating the position (X ′, Y ′) after the moving body from the initial position (X, Y) is performed.
[0043]
Here, in order to make the relationship between the rotation angle of the moving body and the azimuth to advance, the azimuth data S8 obtained from the azimuth sensor (9) and the angular velocity data S9 obtained from the gyro (10) are integrated as angle data, Correct the absolute heading in which the body is moving. Further, since the sensor error accumulates when the data obtained from the above-mentioned sensor is integrated, the accumulated error is canceled based on the position data S10 obtained from the GPS receiver (11) in a certain time period. The current position data is output.
[0044]
Since the current position data obtained in this way includes sensor errors, map matching processing (407) is performed for the purpose of further enhancing the position information. This is because the road data included in the map around the current position read by the data reading unit (408) and the travel locus obtained from the current position calculation unit (406) are compared with each other, and the road having the highest shape correlation. This is a process of aligning the current position with. By applying the map matching process (407), the current position is usually coincident with the traveling road, and the current position information can be output with high accuracy.
[0045]
The current position information obtained in this way is stored in the trajectory storage unit (409) every time a predetermined distance is traveled. The trajectory data is used to draw a trajectory mark on the road on the map corresponding to the road that has been traveled so far.
[0046]
On the other hand, the command analysis unit (401) receives a request from the user by the input device (5), analyzes the request, and controls each unit so that the corresponding processing is executed. For example, when the user requests route guidance to the destination, the display processing unit (412) is requested to display a map in order to set the destination, and the route from the current position to the destination is calculated. The process is requested to the route calculation unit (402).
[0047]
The route calculation unit (402) searches the map data for a route between designated points using a mathematical operation method such as Dijkstra method, and stores it in the route storage unit (403).
At this time, it is possible to obtain a route with the shortest distance between designated points, a route that can be reached in the shortest time, or a route with the lowest cost.
[0048]
The route guidance unit (404) compares the link information of the guidance route stored in the route storage unit (403) with the current position information of the host vehicle obtained by the current position calculation unit (406) and the map match processing unit (407). The voice input / output device (4) is used to notify the user by voice whether the vehicle should go straight ahead or turn left or right before passing an intersection, or proceed on the map displayed on the display (2). The direction to be displayed is displayed, and the route is notified to the user.
[0049]
The data reading unit (408) operates to prepare for reading the map data of the requested area from the map database (3). The display processing unit (412) receives the map data around the point where the display is requested from the data reading unit (408), and develops the graphic with the scale, the drawing method, and the drawing direction specified by the command analysis unit (401). To the frame memory (306). The menu display unit (410) receives an instruction to be output from the command analysis unit (401), transfers various types of required menus and marks to the display processing unit (412), and displays them on the map.
[0050]
The service information display unit (405) interprets the service information such as the store and traffic information received by the communication device (7), develops it into a display form such as an icon, transfers it to the display processing unit (412), and superimposes it on the map. To display.
[0051]
The service information selection unit (411) selects one service information from the plurality of service information displayed and developed by the service information display unit (405). For example, the service information closest to the host vehicle is set as the first candidate for selection, and when the user receives an instruction to select the next service information via the command analysis unit (401), the first candidate is sequentially ordered. Select service information in a direction away from the vehicle.
[0052]
The service information selection method as described above is particularly effective when, for example, the user designates a specific type of business such as a gas station and a plurality of candidates exist in the vicinity of the own vehicle.
[0053]
In the example of the present embodiment described below, each time a selection instruction is received, a single service information is selected, and the selected single service information is displayed. It is not limited to such a configuration. For example, when a selection instruction is received, a predetermined number of service information may be sequentially selected as one set, and the predetermined number of service information included in the selected set may be displayed simultaneously.
[0054]
FIG. 5 is a display example when one piece of facility information is selected from a plurality of pieces of facility information received by the method of the present embodiment.
[0055]
In the display example (501), (502) is a vehicle position mark, and (503) is a facility icon indicating service information received by the communication device (7). The facility icon (503) indicates a facility that can be used during business, and the facility icon (504) smaller than the facility icon (503) indicates an unusable facility.
[0056]
According to this selection method, for example, facility information that is available and closest to the vehicle is selected from the plurality of facility icons, and detailed information on the facility information is displayed in a window as shown in (511). Display and notify the user. An instruction mark such as an arrow shape (510) is displayed on the selected facility information.
[0057]
Here, the method for determining whether or not the facility indicated by the service information can be used is not particularly limited. For example, a configuration in which information indicating whether or not the facility can be used at that time is added in advance to the provided information. Or it is set as the structure judged by the navigation apparatus side from the content of the attribute information for every facility which the provided information shows.
[0058]
Further, until the latest service information is obtained, the determination as to whether or not the current service information can be used may be constantly updated based on the contents of the service information received last time.
[0059]
In this example, the available facilities and the impossible facilities are displayed together. However, only the available facilities may be displayed.
[0060]
FIG. 6 is a flowchart showing an example of processing in the service information display unit (405).
[0061]
In this processing example, the facility information received by the communication means (7) is read (processing 640), and the position (latitude / longitude) of the read facility information is stored in the normalized coordinate system which is the coordinate system of the map database (3). Conversion is performed (process 641). Furthermore, in order to display the said facility information converted into the normalized coordinate system on a display (2), it converts into a display coordinate system (process 642).
[0062]
With reference to the attached information such as full, empty, open, etc. added to the facility information, if it is an available facility (process 643), an icon corresponding to the facility is displayed superimposed on the map (process 644). . The facility determined to be unusable in the process (643) displays an icon different from that in the process (644) on the map (process 645).
[0063]
FIG. 7 is a flowchart showing an example of processing in the service information selection unit (411).
[0064]
The following process flow is a procedure for selecting service information as a first candidate. In the present embodiment, a facility icon that is most likely to be selected by the user is selected from a plurality of facility icons displayed on the map, and an instruction mark such as a cursor is displayed on the facility icon. By doing so, it is intended to increase the probability that a further selection operation by the user is unnecessary.
[0065]
In this processing example, the current position data calculated from the current position calculation unit (406) is read (processing 600). It is determined whether or not a route to the destination has been set with reference to the route storage unit (403) (process 601).
[0066]
If the route is not set, the service information display unit (405) refers to the location of the facility information converted into the normalized coordinate system (process 603), and calculates the distance between the current location O and the facility information. Then, the facility information closest to the current location O among the received facility information is stored (process 604). When all the received facility information is completed (process 605), the facility information closest to the current position O is set as the first candidate for selection, and an instruction mark such as an arrow is set at the position of the facility information (process 606).
[0067]
If the route is set in the process (601), the route information is read from the route storage unit (403) (process 607), and the position of the facility information converted into the normalized coordinate system by the service information display unit (405) is obtained. Reference is made (step 609), and a distance difference between the route information and the facility information is calculated to determine whether the facility information is a route peripheral facility (step 610). If it is a facility around the route, the distance difference between the facility information Pm and the current location O is calculated, and the facility closest to the host vehicle is stored (process 611). When the processing is completed for all the received facility information (processing 612), the facility information closest to the current position O around the route is set as the first candidate for selection, and an instruction mark such as an arrow is set at the position of the facility information. (Process 613).
[0068]
FIG. 8 shows a display example when the processing of FIG. 7 is performed.
[0069]
A display example (700) in FIG. 8A is a display example when the position of the instruction mark is set in the facility information closest to the own vehicle in the process (606) in FIG. (701), (702), (703), and (704) are facility icons received by the communication device (7) and displayed at positions calculated by the service information display unit (405). In this example, in the process (606), the facility icon (701) closest to the own vehicle is selected and the instruction mark (705) is displayed.
[0070]
When the user gives an instruction mark update instruction such as “next” from the input device (5) or the voice input / output device (4), the direction is toward the facility icon far from the vehicle, that is, (701), (702). ), (703), and (704), the instruction marks are moved. When the user gives an instruction such as “Previous”, the instruction mark is moved in a direction closer to the own vehicle than the currently designated facility icon. When the user designates “next” when the facility mark (704) farthest from the own vehicle is instructed, the instruction mark is moved to the facility icon (701) that is the first candidate.
[0071]
When the vehicle is moving, the instruction mark is always moved to the facility icon closest to the vehicle position after the movement, for example, the facility icon (702). Moreover, it is good also as a structure which considers the moving direction of the own vehicle and selects the facility icon closest to the own vehicle position and located in the traveling direction of the own vehicle.
[0072]
The display example (710) in FIG. 8B is a display example when the display position of the instruction mark is set in the facility information that is near the route and closest to the host vehicle in the processing (613). (711) is the route calculated by the route calculation unit (402). A facility icon (702) closest to the vehicle around the route is selected, and an instruction mark (705) is displayed.
[0073]
Similarly to FIG. 8A described above, when “next” is input from the user, the facility is moved away from the vehicle along the route, that is, in the order of (702), (703), and (704). Select an icon. In the present processing example, the facility icon (701) is not selected because it is off the route.
[0074]
In this display example, when the service information selection unit (411) performs selection, the instruction mark (705) is displayed corresponding to the selected facility icon. However, as in the example of FIG. The contents of the service information corresponding to the facility icon may be displayed together with the indication mark.
[0075]
FIG. 9 is a flowchart showing another example of processing in the service information selection unit (411). In this figure, the same processing number is attached | subjected about the same process as the example of FIG. 7, and the detailed description is abbreviate | omitted.

(901), (902), (903), (904), and (905) are facility icons that display the service information received by the communication device (7) at the display position calculated in the service information display unit (405). . Of these, (901), (902), (903), and (904) are facility icons that can be used, and (905) indicates a facility icon that is not available at that time due to being prepared, closed, full, etc. .
[0080]
In this example, a display icon, a color, a size, and the like are displayed in different forms so that the facilities that can be used and the facilities that cannot be used are transmitted to the user at a glance. In addition, among the available facilities, the facility icon (901) closest to the host vehicle is selected as the first candidate, and is set as the first display position of the instruction mark (705).
[0081]
When the user gives an instruction mark update instruction such as “next” from the user via the input device (5) or the voice input / output device (4), in the direction away from the vehicle, that is, (901), (902), ( The indication marks are moved in the order of 903) and (904). When the user gives an instruction such as “Previous”, the instruction mark is moved in a direction closer to the own vehicle than the currently designated facility icon. When the user instructs “next” when the facility mark (904) farthest from the host vehicle is instructed, the instruction mark is moved to the facility icon (901) that is the first candidate.
[0082]
When the host vehicle is moving, the instruction mark is always moved to the facility icon closest to the host vehicle position after the movement, for example, the facility (902). At this time, the facility (905) that cannot be used is excluded from selection.
[0083]
A display example (910) of FIG. 10B is a display example when the display position of the instruction mark is set in the facility information closest to the own vehicle around the route in the process (613) of FIG. (911) is the route calculated by the route calculation unit (402).
