JP 2004-852229 A

If the destination of the vehicle is known, only the traffic information that affects the traveling of the host vehicle can be selected and provided to the driver. Thus, it is conceivable that the driver is requested to set a destination at the time of departure. However, there is a problem in terms of convenience that the setting of the destination is requested every time the vehicle departs.
An object of the present invention is to support setting of a destination and improve convenience.

  The vehicle information providing apparatus according to an aspect of the present invention refers to road map information and stores a destination when the host vehicle passes for each predetermined passing point. Then, when passing through a predetermined passing point, the stored destination history is referred to and the destination that is expected to be headed by the vehicle in the history is presented to the driver as a destination candidate. Then, the destination can be set by the driver's selection operation from the presented destination candidates.

  According to the present invention, the destination at the time when the host vehicle passes is stored for each predetermined passing point. Therefore, when the vehicle passes through the destination thereafter, the destination is recorded from the history of the stored destination. A destination expected to be approaching by the vehicle can be presented to the driver as a destination candidate. The driver can easily set the destination simply by selecting from the presented destination candidates. Thus, the convenience can be improved by supporting the setting of the destination.

<< First Embodiment >>
"Constitution"
FIG. 1 is a schematic configuration diagram of a vehicle information providing apparatus.
The vehicle information providing device 11 is a navigation system mounted on a vehicle, and includes a GPS receiver 13, a road traffic information receiver 13, a sensor group 14, a storage device 15, a controller 16, a display 17, And a speaker 18.

  The GPS receiver 12 acquires current position information of the host vehicle. This GPS receiver 12 receives radio waves from four or more GPS satellites, and measures the current position (longitude, latitude, altitude) of the vehicle based on the distance from each GPS satellite determined from the time difference between transmission and reception. And determine the direction of travel. As a positioning method, a single code positioning method based on modulation of a carrier wave is generally used. However, DGPS (relative positioning) with improved positioning accuracy by receiving correction information generated by another base station whose position is fixed. Method).

  The road traffic information receiver 13 uses, for example, VICS (registered trademark), FM multiplex broadcasting, optical vehicle detector (optical beacon), radio beacon, etc., traffic regulation information, traffic fault information, traffic jam information, required time information, etc. Receive road traffic information. Not limited to VICS (registered trademark), dedicated short range communication (DSRC), which is one of two-way wireless communication technologies, may be used.

The sensor group 14 includes, for example, a wheel speed sensor, a shift sensor, an ignition switch, and the like.
The wheel speed sensor detects wheel speeds Vw _{FL to} Vw _RR of each wheel. The wheel speed sensor includes, for example, a sensor rotor that rotates together with a wheel and has a protrusion (gear pulser) formed on a circumference thereof, and a detection circuit that includes a pickup coil provided to face the protrusion of the sensor rotor. Then, the change in magnetic flux density accompanying the rotation of the sensor rotor is converted into a voltage signal by the pickup coil and output to the controller 16. The controller 16 determines the wheel speeds Vw _{FL to} Vw _RR from the input voltage signal, and calculates, for example, the wheel speed average value of the non-driven wheels (driven wheels) or the wheel speed average value of all the wheels as the vehicle speed.

The shift sensor detects a shift position of the transmission. This shift sensor includes, for example, a plurality of Hall elements, and outputs respective ON / OFF signals to the controller 16. The controller 16 determines the shift position from the input ON / OFF signal combination.
The ignition switch detects ON / OFF of the ignition. This ignition switch outputs a voltage signal corresponding to ON / OFF of the ignition to the controller 16 through, for example, a detection circuit of a normally open contact. The controller 16 determines the ignition ON / OFF from the input voltage signal.

  The storage device 15 is composed of a DVD-ROM drive, a hard disk drive, a flash memory drive, etc., and road map information including road type, road alignment, lane width, vehicle traffic direction, etc., on a non-volatile electronic storage medium. I remember it. In the road map information, a road network is constructed by nodes and links. Alternatively, the road map information database may be managed by a server, and only the updated road map information difference data may be acquired through a telematics service, for example, and the road map information stored in the storage device 15 may be updated.

The storage device 15 includes a destination matrix 21 and a route matrix 22.
The destination matrix 21 is formed for each node or link of the road map information, and stores the destination when the host vehicle passes.
FIG. 2 is a diagram illustrating the destination matrix.
When passing the point P1, either the point P3 or the point P5 is set as the destination, and the number of times of going to the point P3 and the number of times going to the point P5 is counted as the destination matrix. Here, the vehicle passes through the point P1 six times, one of which is directed to the point P3 and five of which is directed to the point P5. In this way, the destination when the host vehicle passes is stored as the destination matrix 21.

The route matrix 22 is formed for each node corresponding to the branch point of the road map information, and stores the route selected by the own vehicle.
FIG. 3 is a diagram illustrating the course matrix.
The point P2 is an intersection of the crossroads, and links connected to the point P2 are i21, i22, i23, and i24, and from which link the point P2 is entered and the link is counted is counted. Here, a route from the link i21 to the point P2, and a route to the link i22 by a right turn is a, a route to the link i23 by a straight turn is b, a route to the link i24 by a left turn is c, and the number of times is Counting. In this way, the route selected by the host vehicle at the branch point is stored as a route matrix.

In addition, not only where to go to point P2 from link i21 and going to link i22, i23, i24, but of course, when entering from link i22, entering from link i23, and entering from link i24 Are stored in the same procedure. That is, the route from the link i22 to the links i21, i23, i24, the route from the link i23 to the links i21, i22, i24, and the route from the link i24 to the links i21, i22, i23, also go to each link. I will remember the number of times.
The above is the description of the storage device 15.

The controller 16 is composed of a microcomputer, for example, and drives the display 17 and the speaker 18 in accordance with road guidance information to be provided to the driver. The road guidance information is current position information received by the GPS receiver 12, road map information read from the storage device 15, a route to the destination, road traffic information received by the road traffic information receiver 13, and the like. .
In the current position information, the current position information received by the GPS receiver 12 may include an error, or the radio wave from the GPS satellite may not be temporarily received. Therefore, accuracy is improved by dead reckoning navigation or map matching. It is increasing.

  Dead reckoning navigation is based on the travel distance obtained from the vehicle speed sensor, the turning angle of the vehicle obtained from the gyro, the inclination angle of the vehicle obtained from the acceleration sensor, the height change amount, and the traveling direction of the vehicle obtained from the GPS receiver 12. The travel position of is calculated at a constant cycle. In the map matching, the current position calculated by dead reckoning and the road map information read from the storage device 15 are compared to match the current position information with the road map information, thereby improving accuracy.

The display 17 displays road guidance information. The display 17 is provided in the vicinity of the dashboard so that the driver can visually recognize and operate the display 17 and includes, for example, a touch panel including a liquid crystal display and an operation input unit. Therefore, it is possible to detect a user's touch operation on the screen and perform various settings based on the touch position.
The speaker 18 outputs voice guidance as road guidance information. This speaker 18 is provided in the passenger compartment and radiates sound corresponding to an electrical signal.

The controller 16 includes a destination candidate presentation unit 31, a route candidate presentation unit 32, and a destination setting unit 33.
The destination candidate presenting unit 31 refers to the history of the destination stored in the destination matrix 21 when passing through the node or the link, and the destination predicted to be the host vehicle in the history is displayed. And displayed on the display 17 as a destination candidate. For example, the destination candidates are displayed in descending order of the frequency stored as the destination.

The route candidate presentation unit 32 refers to the route history stored in the route matrix 22 when heading to the next branch point, and displays the route predicted to be the host vehicle in the history as a route candidate on the display 17. To do. For example, the route candidate is indicated by an arrow, and the frequency toward the route candidate is presented.
The destination setting unit 33 sets a destination according to an input via the display 17. For example, the destination can be set from the address, name, telephone number, and the like. Further, the destination can be set by the driver's touch operation from the destination candidates presented by the destination candidate presentation unit 31.

FIG. 4 shows a presentation example of destination candidates and course candidates at time t1.
This is an example of a navigation screen, and an arrowhead arrow in the center of the screen indicates the current position 41 of the host vehicle, and the host vehicle is approaching a branch point. A destination candidate 42 is presented on the left side of the screen. For each candidate, supplementary information such as the frequency (probability) of traveling to this destination in the past, the distance to the destination, the direction of the destination, and the like is also written for each candidate.

  Here, two destination candidates are presented in the vertical direction in the order of frequency, one is “home”, and the other is “convenience store ○ chome store”. According to our history, when you follow this road, you are either going home or going to a convenience store, heading home with a frequency of about 67%, and going to a convenience store with a frequency of about 33%. It is shown that. When there are three or more destination candidates 42 that do not fit on the screen, all the destination candidates 42 can be presented by a window scrollable in the vertical direction.

  Moreover, the course candidate 43 is presented at the position of the branch point where the host vehicle is approaching. The course candidates 43 are displayed by, for example, block arrows, and the frequency (probability) of progress in the past is also written for each candidate. Here, there are a course that goes straight at the branch point and a course that turns left at the branch point, and according to the history, it goes straight at the branch point with a frequency of approximately 67% and turns left at the frequency with a frequency of approximately 33%. It shows that you are doing. The block arrows are changed in thickness, length, etc. according to the frequency, and the block arrows are thicker and longer as the frequency increases. In addition, the block arrow is made transparent so that the map itself is not completely hidden by the block arrow.

  In addition, although the block arrow is superimposed and displayed on the line which shows a road, you may offset and display a block arrow so that it may not overlap with the line which shows a road. Moreover, although the block arrow and the frequency are displayed in an overlapping manner, the frequency may be displayed with an offset with respect to the block arrow, for example, so as not to overlap each other. In addition, a general arrow or a hand-shaped instruction mark may be used instead of a block arrow. In other words, other marks and symbols may be used as long as the direction can be indicated, and the design is arbitrary. .

FIG. 5 shows another example of presentation of destination candidates at time t1.
Here, the destination candidate 42 is presented as a sign. When the host vehicle is approaching the branch point, it is indicated with a block arrow that it goes to the home when going straight at the branch point and goes to the convenience store when turning left at the branch point. The character size is changed according to the frequency of going to each destination. The higher the frequency, the larger the character size. For each candidate, supplementary information such as the frequency of traveling to the destination through the road in the past, the distance to the destination, the direction of the destination, etc. may also be written. Further, as the frequency is higher, the block arrow may be enlarged or the color may be changed and highlighted.

FIG. 6 shows a presentation example of destination candidates and course candidates at time t2.
Here, a state after the vehicle turns left at the aforementioned branch point is shown. In this case, the probability of approaching a convenience store is approximately 100%. Therefore, since the destination candidates 42 are narrowed down to one, only “Convenience store ○ Chome store” is presented. The next branch point is a crossroad, but the probability of going straight without turning left or right is approximately 100%. Therefore, at the next branch point, only the straight block arrow is presented and the probability is also shown.
The above is an explanation of destination candidates and course candidates.

Next, an information providing process executed by the controller 16 every predetermined time (for example, 10 msec) will be described.
FIG. 7 is a flowchart illustrating an example of the information providing process.
First, in step S101, it is determined whether or not the ignition switch is ON. When the ignition switch is ON, the process proceeds to step S102, and when the ignition switch is OFF, the process proceeds to step S114.
In step S102, the current position of the host vehicle is detected.

In a succeeding step S103, it is determined whether or not the trip ID is not set. When the trip ID has not been set, the process proceeds to step S104, and when the trip ID has been set, the process proceeds to step S106. Note that when the ignition switch is turned on, the trip ID is not set.
In step S104, a trip ID is set. The trip ID is a number using, for example, date.

In the subsequent step S105, the trip flag is set to ft = 1. Note that when the ignition switch is turned on, the trip flag is reset to ft = 0.
In subsequent step S106, the road map information is referred to.
In subsequent step S107, a destination candidate presentation process described later is executed to present a destination candidate.
In subsequent step S108, a course candidate presentation process described later is executed to present a course candidate.
In the subsequent step S109, the route selected by the host vehicle is stored in the route matrix 22 every time the node corresponding to the branch point is passed. That is, the count of the selected route is set to +1 together with the current trip ID.

In a succeeding step S110, it is determined whether or not the destination is set by the driver. When the destination is set, the process proceeds to step S111, and when the destination is not set, the process returns to the predetermined main program as it is.
In step S111, it is determined whether or not the destination has been reached. When it has arrived at the destination, the process proceeds to step S112, and when it has not arrived at the destination, it returns to the predetermined main program as it is.
In step S112, the current position that is the destination of the current trip is stored in the destination matrix 21 in all nodes or links on the route from the departure point to the destination. That is, the destination count is set to +1 together with the current trip ID.

In the subsequent step S113, the trip flag is reset to ft = 0, and then the process returns to the predetermined main program.
In step S114, it is determined whether or not the trip flag is set to ft = 1. When the trip flag is set to ft = 1, it is determined that the destination is not stored, and the process proceeds to step S115. On the other hand, when the trip flag is reset to ft = 0, it is determined that the destination has been stored, and the process returns to the predetermined main program as it is.

In step S115, the current position is stored as the destination. That is, the current location that is the destination in the current trip is stored in the destination matrix 21 in all nodes or links on the route from the departure point to the current location.
In the subsequent step S116, the trip flag is reset to ft = 0 and then the process returns to the predetermined main program.
The above is the description of the information providing process.

Next, the destination candidate presentation process will be described.
FIG. 8 is a flowchart illustrating an example of destination candidate presentation processing.
First, in step S171, it is determined whether or not the next passing point has been identified. When the next passing point can be specified, the process proceeds to step S172, and when the next passing point cannot be specified, the process directly returns to the predetermined main program.

In step S172, it is determined whether or not there is a destination history in the destination point destination matrix 21. When there is a destination history in the destination matrix 21 at the passing point, the process proceeds to step S173, and when there is no destination history in the destination matrix 21 at the passing point, the process returns to the predetermined main program as it is.
In step S173, the destination matrix 21 of the passing points is referred to, and the destination predicted to be headed by the host vehicle is presented to the driver as a destination candidate, and then the routine returns to the predetermined main program. Here, the destination candidates are presented in descending order of the frequency stored as the destination.

Next, the course candidate presentation process will be described.
FIG. 9 is a flowchart illustrating an example of a course candidate presentation process.
First, in step S181, it is determined whether or not the next branch point has been identified. When the next branch point can be specified, the process proceeds to step S182, and when the next branch point cannot be specified, the process directly returns to the predetermined main program.

In step S182, it is determined whether or not there is a course history in the course matrix 22 at the branch point. When there is a course history in the course matrix 22 at the branch point, the process proceeds to step S183, and when there is no course history in the course matrix 22 at the branch point, the process returns to the predetermined main program as it is.
In step S183, the route matrix 22 of the branch point is referred to, and the route expected to be headed by the host vehicle is presented to the driver as a route candidate, and then the process returns to the predetermined main program. Here, along with the route candidate, the frequency toward the route candidate is also presented.

<Action>
Next, the operation of the first embodiment will be described.
There is a problem in terms of convenience that the setting of the destination is required every time the user departs.
Therefore, a destination matrix 21 is prepared for each node or link of the road map information, and the destination when the host vehicle passes through is stored therein. Specifically, when the vehicle arrives at the destination (“Yes” at step S111), the current position is set in the destination matrix 21 of each node or each link on the route from the departure viewpoint to the current position. Is stored as a destination of the trip (movement) (step S112). If the destination has not been set (determination in step S110 is “No”), when the ignition is turned off (determination in step S101 is “No”), the current position is regarded as the destination and the storage process is performed. (Step S115).

  Thereafter, when the vehicle passes through the destination, the destination history stored in the destination matrix 21 is referred to, and the destination predicted to be heading from the history is displayed as the destination candidate 42. 17 (step S107). The destination predicted that the host vehicle is heading is one that is frequently stored as the destination. Thus, even after the departure, that is, after the start of the current trip (movement), the driver simply selects one of the destination candidates 42 displayed on the display 17 by a touch operation. The ground can be easily set (step S110). Thus, the convenience can be improved by supporting the setting of the destination.

Further, a route matrix 22 is prepared for each node corresponding to a road branch point, and the route selected by the host vehicle is stored therein (step S109).
Thereafter, when the vehicle passes there, the route history stored in the route matrix 22 is referred to, and the route expected to be selected by the host vehicle from the history is presented on the display 17 as the route candidate 43 (step 17). S108). The route expected to be selected by the host vehicle is that the frequency stored as the route is equal to or higher than a threshold (for example, 30%), and the frequency is also presented. Thereby, even if the route guidance is not started by the navigation system, the driver can be reminded of the next route or necessary action (reminder).

If the road only passes several times a year, it is easy to forget the detailed route. Even in areas where similar scenery continues or there are many similar buildings, there is a tendency for mistakes in the road. Therefore, convenience is improved by reminding the next route and necessary actions as local support.
On the other hand, by presenting a route that passes frequently, a route that has never been passed becomes clear. Therefore, it can be a tool that stimulates curiosity for drivers who want to choose a path they have never been to before.

Note that if the destination and route history are stored, the data capacity may be increased, but according to the inventors' calculations, the destination matrix 21 in FIG. 2 and the route matrix 22 in FIG. It has been found that if a simple matrix is used, even if it corresponds to the whole country of Japan, it will take only a few mega. Therefore, the data capacity is not a big problem.
Further, since the vehicle information providing apparatus 11 is not connected to the network and is a stand-alone device that operates independently, there is little possibility that the accumulated history information of the destination and the route is leaked to the outside.

<< Application Example 1 >>
In the first embodiment, the destination candidates 42 are presented in descending order of the frequency stored as the destination in the history, but the present invention is not limited to this. For example, the order in which the destination candidates 42 are presented may be adjusted according to at least one of date, time zone, season, continuous operation time, remaining fuel amount, and remaining battery charge.

FIG. 10 is a schematic configuration diagram illustrating the vehicle information providing apparatus according to the first application example.
The sensor group 14 detects a date, a time zone, a season, a continuous operation time, a remaining fuel amount, a remaining battery charge amount, and the like.
The use of automobiles becomes a habit to some extent. For example, if you leave your home on a weekday morning, your destination is likely to be a work location, and if you leave your home on a holiday morning, your destination is likely to be outside your work location. In addition, when leaving home on a holiday, the destination may differ between the hot season and the cold season. Therefore, if the order of presenting the destination candidates 42 is adjusted in consideration of the date, time zone, and season, the destination candidates 42 with higher accuracy can be presented.

Moreover, when driving a relatively long distance at homecoming or the like, whether to take a break depends on the continuous driving time. Therefore, if the order of presenting the destination candidates 42 is adjusted in consideration of the continuous operation time, the destination candidates 42 with higher accuracy can be presented.
In addition, in the case of an engine vehicle, whether or not to stop at a fueling station or a charging station differs depending on the remaining amount of fuel, and in the case of an electric vehicle, depending on the remaining battery charge. Therefore, the destination candidate 42 with higher accuracy can be presented by adjusting the order in which the destination candidates 42 are presented in consideration of the remaining fuel amount and the remaining battery charge amount.

<< Second Embodiment >>
"Constitution"
In the second embodiment, road traffic information is selected according to destination candidates, and only road traffic information necessary for the host vehicle is presented.
FIG. 11 is a schematic configuration diagram of the vehicle information providing apparatus 11 according to the second embodiment.
Here, except that the storage device 15 includes the specific route table 23 and the controller 16 includes the road traffic information presentation unit 34, the configuration is the same as that of the above-described first embodiment. Detailed description is omitted.
The specific route table 23 sets a route that frequently passes as a specific route, and stores the route and frequency as a set.

FIG. 12 is a diagram explaining the specific route table 23.
Here, an example is a table in which a specific route number, the number of appearances, a departure place, a route (node number), and a destination are set. For example, a route from the home to the work place is set as the specific route N1, and among them, N1-1, N1-2, and N1-3 are registered as three routes that frequently pass. Each route departs from home and remembers which node it heads to work and counts the number of times.
The road traffic information presentation unit 34 presents only the road traffic information on the route from the current position to the destination among the road traffic information acquired by the road traffic information receiver 13 on the display 17.

Next, an information providing process executed by the controller 16 will be described.
FIG. 13 is a flowchart illustrating information presentation processing according to the second embodiment.
Here, except that new processing of steps S201, S202, and S203 is added, the same processing as that of the first embodiment described above is executed, and thus detailed description of common portions is omitted.

Step S201 is processing to be shifted when it is determined in step S110 that the destination is set. Here, road traffic information presentation processing described later is executed to present road traffic information.
Step S202 is processing to be performed after the destination storage processing in step S112. Here, the specific route storage processing described later is executed, and the storage processing of the specific route table 23 is performed.
Step S203 is a process to be performed after the current position is set as the destination in step S115. Here, the same process as the specific route storage process in step S202 is performed, and thus the description thereof is omitted.

Next, road traffic information presentation processing will be described.
FIG. 14 is a flowchart illustrating an example of road traffic information presentation processing.
First, in step S211, it is determined whether road traffic information has been acquired. When the road traffic information can be acquired, the process proceeds to step S212. When the road traffic information cannot be acquired, the process returns to the predetermined main program as it is.
In step S212, it is determined whether or not the current trip is a route registered in the specific route table 23. If the current trip is a route registered in the specific route table 23, the process proceeds to step S213. If the current trip is not a registered route, the process proceeds to step S215.

In step S213, only the road traffic information corresponding to the specific route, that is, the information that can affect the current trip is selected from the road traffic information.
In the subsequent step S214, only the selected road traffic information is presented on the display 17, and then the process returns to the predetermined main program.
In step S215, only road traffic information included in the drawing area of the screen set by the navigation system is selected from the road traffic information, and then the process proceeds to step S214.

Next, the specific route storage process will be described.
FIG. 15 is a flowchart illustrating an example of the specific path storage process.
First, in step S221, it is determined whether or not the storage condition of the specific route is satisfied. The storage condition is, for example, that the frequency is equal to or higher than a threshold value. When the storage condition of the specific route is satisfied, the process proceeds to step S222, and when the storage condition of the specific route is not satisfied, the process returns to the predetermined main program as it is.

In step S222, it is determined whether the route is unregistered in the specific route table 23. When the route is not registered in the specific route table 23, the process proceeds to step S223. When the route is registered in the specific route table 23, the process proceeds to step S225.
In step S223, it is determined whether additional registration as a specific route is possible. Whether or not additional registration as a specific route is possible is determined by whether or not there is a vacant space that can be additionally registered. When the additional registration can be performed, the process proceeds to step S224. When the additional registration cannot be performed, the process proceeds to step S226.

In step S224, the program is stored in the specific route table 23, and the subtotal and the total count are incremented by +1, and then the process returns to the predetermined main program.
In step S225, it is stored in the specific route table 23, and the subtotal count is incremented by one.
In the subsequent step S225, the program is stored in the specific route table 23, the total count is incremented by 1, and then the process returns to the predetermined main program.

<Action>
Next, the operation of the second embodiment will be described.
As long as the destination of the vehicle is known, it is possible to select only the road traffic information that affects the traveling of the host vehicle and provide it to the driver.
Therefore, when the destination is set (determination in step S110 is “Yes”), only those that affect the traveling of the host vehicle are selected. Specifically, when the current trip is a route registered in the specific route table 23 (the determination in step S212 is “Yes”), only the road traffic information corresponding to the specific route is selected (step S213). This is presented (step S214). Thereby, unnecessary information presentation can be suppressed, and only necessary and sufficient road traffic information can be presented, thereby improving convenience.
In the second embodiment, the same effects as those in the first embodiment described above can be obtained, and detailed description thereof will be omitted.
