Description

The present invention relates to an automatic driving availability notification system that notifies the driver whether or not automatic driving is possible on a freely traveled route.

Conventionally, when searching for a route from a departure point to a destination, a route that includes an automatically controlled inoperable road with low position detection accuracy is avoided, and a route with the shortest distance that does not include an automatically controlled inoperable road. There is known a vehicle control device for obtaining the above (see, for example, Patent Document 1). As a result, it is possible to provide route guidance so that the vehicle travels according to the searched route, and to perform automatic control operation as needed.

Japanese Unexamined Patent Publication No. 2011-118603

By the way, in the vehicle control device disclosed in Patent Document 1 described above, by setting a starting point and a destination and searching for a route between them, it is possible to know the shortest route that does not include a road that cannot be automatically controlled and operated. However, there is a problem that it is not possible to know whether or not automatically controlled driving is possible except for the route obtained by the search, that is, whether or not automatically controlled driving is possible.

The present invention has been created in view of these points, and an object of the present invention is to provide an automatic driving possibility notification system capable of knowing whether or not automatic driving is possible on a route on which a driver has freely traveled. be.

In order to solve the above-mentioned problems, the automatic driving possibility notification system of the present invention has an automatic driving determination means for repeatedly determining whether or not automatic driving is possible on the road on which the own vehicle has passed, and a result of repeated determination by the automatic driving determination means. It is provided with an automatic driving determination result acquisition means for acquiring the information indicating the above, and a notification means for notifying the information acquired by the automatic driving determination result acquisition means. As a result, the driver can know whether or not automatic driving is possible on the road on which he / she has freely traveled.

In addition, it is further provided with a guiding means for guiding the traveling of the own vehicle along the traveling route to the destination, and the automatic driving determining means can determine whether or not the automatic driving is possible when the guiding means is not providing guidance. desirable. Alternatively, an automatic driving means for driving the own vehicle along the traveling route to the destination without the driver's driving operation is further provided, and the automatic driving determination means is when the own vehicle is not driven by the automatic driving means. It is desirable to determine whether or not automatic driving is possible. It is possible to know whether or not automatic driving is possible on this road when traveling on a road other than the driving route that guides the driving of the own vehicle and the automatic driving route.

In addition, it is desirable that the above-mentioned automatic driving determination means determine whether or not automatic driving is possible by examining the road on which the own vehicle has passed whether or not there is high-precision map information necessary for performing automatic driving. Since it is necessary to prepare high-precision map information for the road to be driven in order to perform automatic driving, it is necessary to know whether or not automatic driving is possible by checking the presence or absence of this high-precision map information. Is possible.

In addition, the own vehicle position detecting means for detecting the own vehicle position and the own vehicle position correcting means for correcting the own vehicle position detected by the own vehicle position detecting means to a position along the surrounding road are further added. In addition, the automatic driving determination means determines whether or not automatic driving is possible when the position of the own vehicle is corrected on the road by map matching. As a result, if the vehicle position cannot be corrected on the road by map matching, for example, if you are driving in a parking lot around your home or on a narrow street, you will not be subject to the same automatic driving as other roads. Since it is known in advance, the judgment accuracy can be improved by excluding it from the judgment target of automatic operation.

Further, it is desirable that the above-mentioned automatic driving determination result acquisition means acquires the result of determination performed at a predetermined time interval or distance interval. As a result, even if the operation is suddenly terminated due to a power off or the like, it is possible to acquire and retain the determination results up to that point each time.

Further, it is desirable that the above-mentioned notification means notifies when the ignition switch or the accessory switch is turned off. As a result, notification is given when the engine is stopped and the vehicle is parked, so that it is possible to confirm whether or not automatic driving is possible while the memory of the route traveled up to that point is certain.

Further, it is desirable that the above-mentioned notification means perform notification by voice. If you give a display notification after turning off the ignition switch or accessory switch, you may be worried that the power supply to the device that displays this display will not end, but there is little concern about voice notification. Therefore, it is possible to avoid unnecessarily anxious the driver.

In addition, the above-mentioned notification means notifies the road that the own vehicle has passed through, including the ratio of the sections that can be automatically driven, based on the information indicating the determination results of a plurality of times acquired by the automatic driving judgment result acquisition means. It is desirable to do it. It is thought that the number of roads subject to autonomous driving will gradually increase, and it is not very likely at this point that 100% autonomous driving is possible on roads where drivers are free to drive, but autonomous driving is possible on such roads. It becomes possible to easily know the possible degree. In addition, when the degree to which automatic driving is possible is large, knowing it also has the effect of encouraging driving by automatic driving.

Further, the notification history storage means for storing the notification history by the above-mentioned notification means is further provided, and the notification means notifies when the contents are duplicated with the previously notified contents based on the history stored in the notification history storage means. It is desirable to suppress it. As a result, it is possible to improve the annoyance of being notified of the same content on the same road each time.

Further, a route search means for setting a travel route that can be automatically driven between the start point and the end point of the series of repetitive determinations by the above-mentioned automatic driving determination means by the route search process is further provided, and the notification means is the automatic driving determination. It is desirable to notify the information acquired by the result acquisition means and propose a traveling route set by the route search means. As a result, it is possible to know whether or not automatic driving is possible on a freely driven road, as well as to know an alternative route that can be automatically driven, and it is possible to promote driving by automatic driving using the alternative route.

It is a figure which shows the modification of the navigation device.

Hereinafter, an in-vehicle system according to an embodiment to which the automatic driving possibility notification system of the present invention is applied will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an in-vehicle system of one embodiment. As shown in FIG. 1, the in-vehicle system of the present embodiment includes an automatic driving device 100, a navigation device 200, and a high-precision map information management device 300.

The automatic driving device 100 performs automatic driving in which the own vehicle is driven along the traveling route to the destination set by the navigation device 200 without the driver's driving operation. For example, in this embodiment, level 3 or level 4 automatic operation is assumed. Further, since the specific method for realizing automatic driving is not directly related to the content of the present invention, the description thereof will be omitted, but the present invention will be applied to automatic driving using various techniques realized at present or in the future. be able to. In addition, among the set travel routes, the roads (links) for which high-precision map information is prepared can be automatically driven, and the entire travel route set by the navigation device 200 can be automatically driven. Not necessarily.

The navigation device 200 performs a navigation operation for guiding the traveling of the vehicle (own vehicle) on which the navigation device 200 is mounted based on the map data. For this purpose, the navigation device 200 includes a map DB (database) 210, a vehicle position calculation unit 220, a GPS receiver 222, a route search processing unit 230, a route guidance processing unit 240, a map display processing unit 250, and a display unit 252. It includes a storage information acquisition processing unit 260, an automatic operation availability notification unit 270, and a speaker 272. The navigation device 200 can be realized by executing a predetermined operation program using a CPU, ROM, RAM, etc., except for some configurations such as a GPS receiver 222, a display unit 252, and a speaker 272. ..

The map DB 210 displays a map image or the like around the position of the own vehicle, a route search operation for calculating an optimum travel route connecting the departure point and the destination, and travel of the own vehicle along the travel route obtained by the route search. The map data required for the route guidance operation (guidance operation) that guides the vehicle is stored. This map data is not required to be as accurate as the high-precision map information required for autonomous driving. The map DB 210 stores map data in units of rectangular map leaves divided into appropriate sizes by longitude and latitude. The map data of each map leaf can be specified and read by specifying the map leaf number. The map DB 210 is realized by a hard disk device or a semiconductor memory, or by a DVD and its reading device. Further, the map DB 210 may be replaced with a communication device to acquire map data from an external map distribution server (not shown).

The vehicle position calculation unit 220 calculates the own vehicle position based on the detection data output from the GPS receiver 222, and corrects the own vehicle position when the calculated own vehicle position is not on the road in the map data. Perform map matching processing. As an example, the GPS receiver 222 is used to detect the position of the own vehicle, but a self-contained navigation sensor using a directional sensor, a distance sensor, or the like may be used in combination to improve the detection accuracy.

The route search processing unit 230 calculates a travel route that costs the least from the departure point to the destination by route search processing using the designated search conditions.

The route guidance processing unit 240 creates drawing data for displaying the travel route obtained by the route search processing by the route search processing unit 230 on the map image and displaying the guide map of the right / left turn intersection. , Generates voice signals such as intersection guidance necessary for guiding the traveling of a vehicle along a traveling route.

The map display processing unit 250 draws a map image around the position of the own vehicle, and superimposes a traveling route drawn by the route guidance processing unit 240, a guide map of a right / left turn intersection, and the like on the map image, and the screen of the display unit 252. Display on.

The storage information acquisition processing unit 260 requests the high-precision map information management device 300 to determine the storage of high-precision map information when a predetermined condition is satisfied after the navigation device 200 starts operation. Further, the storage information acquisition processing unit 260 receives and stores "storage information" indicating whether or not the high-precision map information is stored, which is repeatedly sent from the high-precision map information management device 300 in response to this request.

The automatic operation availability notification unit 270 aggregates the "stored information" stored by the stored information acquisition processing unit 260 when the power of the navigation device 200 is turned off (for example, when the ignition switch or the accessory switch is turned off). Notify the driver. For example, an utterance process is performed in which the aggregated result is output as voice from the speaker 272. In the present embodiment, the navigation device 200 terminates its operation when this notification ends after the power off instruction is instructed.

The high-precision map information management device 300 stores high-precision map information, sets a travel route for automatic driving, and performs storage determination processing of high-precision map information based on a request from the navigation device 200. For this purpose, the high-precision map information management device 300 includes a high-precision map DB 310, an automatic driving route creation unit 320, an automatic driving determination unit 330, and a storage determination processing unit 340.

The high-precision map DB 310 stores high-precision map information, which is high-precision map data required for automatic driving. All sections of expressways are scheduled to be created sequentially as needed for general roads, and the version of high-precision map information created at any time is stored in the high-precision map DB 310. do. The high-precision map DB 310 is realized by a hard disk device or a semiconductor memory, or by a DVD and its reading device, like the map DB 210 provided in the navigation device 200. Further, the high-precision map DB 310 may be replaced with a communication device to acquire high-precision map information from an external map distribution server (not shown).

The automatic driving route creation unit 320 extracts a section capable of automatic driving from the traveling route to the destination set by the route search processing unit 230 of the navigation device 200, and specifically, high-precision map information is obtained. Extract the corresponding section and create an automatic driving route. Information about the created automatic driving route is sent to the automatic driving device 100. The automatic driving determination unit 330 determines whether or not automatic driving is in progress by the automatic driving device 100.

When the storage determination processing unit 260 of the navigation device 200 requests the storage determination, the storage determination processing unit 340 performs a storage determination of high-precision map information corresponding to the road on which the vehicle is traveling, and the resulting high-precision map. Information indicating whether or not the information is stored is sent back to the stored information acquisition processing unit 260 at predetermined time intervals.

The storage judgment processing unit 340 described above is used as an automatic driving judgment means, the stored information income processing unit 260 is used as an automatic driving judgment result acquisition means, the automatic driving possibility notification unit 270 is used as a notification means, and the route guidance processing unit 240 is used as a guidance means. The automatic driving device 100 corresponds to the automatic driving means, the GPS receiver 222 corresponds to the own vehicle position detecting means, and the own vehicle position calculation unit 220 corresponds to the own vehicle position correcting means.

The in-vehicle system of the present embodiment has such a configuration, and the operation thereof will be described next. FIG. 2 is a flow chart showing an operation procedure of the navigation device 200 that acquires a stored state of high-precision map information while freely traveling on an arbitrary road by the driver's own operation and notifies the result.

The storage information acquisition processing unit 260 determines whether or not the vehicle position matches the road (whether the vehicle position is corrected on the road by map matching by the vehicle position calculation unit 220) (step 100). .. For example, if the map matching is in progress immediately after leaving the home parking lot and the position of the own vehicle is off the road on the map, a negative judgment is made and this judgment is repeated. Further, when the map matching is completed, the position of the own vehicle is corrected, and the vehicle is placed on the road on the map, an affirmative judgment is made in the determination in step 100.

Next, the stored information acquisition processing unit 260 determines whether or not the guidance operation by the route guidance processing unit 240 has been started (step 102). When the guidance operation is started, an affirmative judgment is made and the process ends.

If the guidance operation is not started, a negative determination is made in the determination in step 102. Next, the storage information acquisition processing unit 260 requests the high-precision map information management device 300 to determine the storage of high-precision map information (step 104). After that, the stored information acquisition processing unit 260 determines whether or not "stored information" indicating whether or not the high-precision map information is stored has been sent from the high-precision map information management device 300 in response to this request (step 106). ). If it is sent, an affirmative determination is made, and the stored information acquisition processing unit 260 stores the received stored information (step 108).

After this storage operation, or after a negative determination is made in the determination in step 106 without the stored information being sent from the high-precision map information management device 300, the stored information acquisition processing unit 260 has its own vehicle position on the road. It is determined whether or not the vehicle deviates from the above range (whether or not the vehicle position deviates from the range that can be corrected on the road by map matching by the vehicle position calculation unit 220) (step 110). If the vehicle position is on the road, a negative determination is made, and the process returns to step 102 to repeat the determination of whether or not to start guidance.

In addition, if the position of the own vehicle deviates from the road (assuming that the vehicle enters a parking lot at home or a road that is not subject to map matching such as a narrow street near the home), step 110 An affirmative judgment is made in the judgment. Next, the stored information acquisition processing unit 260 determines whether or not the power of the navigation device 200 is turned off (whether or not the ignition switch or accessory switch of the vehicle is turned off) (step 112). A negative decision is made until the power is turned off, and this decision is repeated.

Further, when the power is turned off, an affirmative determination is made in the determination in step 112. Next, the automatic operation availability notification unit 270 performs an utterance process of outputting the result of totaling the "stored information" stored by the stored information acquisition processing unit 260 by voice (step 114). In this way, a series of processes is completed.

FIG. 3 is a flow chart showing an operation procedure of storage determination of high-precision map information performed by the high-precision map information management device 300.

The storage determination processing unit 340 determines whether or not a request for storage processing of high-precision map information has been received from the storage information acquisition processing unit 260 of the navigation device 200 (step 200). If not received, a negative judgment is made and this judgment is repeated.

Further, when the request for the storage process is received, an affirmative judgment is made in the determination in step 200. Next, the automatic driving determination unit 330 determines whether or not automatic driving is in progress (step 202). If the vehicle is in automatic operation, a positive judgment is made and the process ends.

Further, when the automatic operation is not in progress, a negative determination is made in the determination in step 202. Next, the storage determination processing unit 340 performs storage determination processing of high-precision map information corresponding to the traveling road (step 204). Specifically, the storage determination processing unit 340 has high-precision map information (high) for the road corresponding to the current vehicle position (the vehicle position is acquired from the vehicle position calculation unit 220 of the navigation device 200). Whether or not the high-precision map information corresponding to the road at the corresponding location is stored in the high-precision map DB 310) is examined.

After that, the storage determination processing unit 340 determines whether or not a certain period of time has elapsed (step 206). A negative determination is made until a certain period of time elapses, and the process returns to step 202 to repeat the automatic operation determination. Further, when a certain time elapses, a positive judgment is made in the determination in step 206. Next, the storage determination processing unit 340 supplies the storage information acquisition processing unit 260 of the navigation device 200 with "storage information" indicating whether or not the high-precision map information is stored as the storage determination processing result until a certain time elapses. (Step 208). After that, the process returns to step 202 and the automatic operation determination is repeated. In step 206 described above, it is determined whether or not a certain time has passed, but instead, it may be determined whether or not the vehicle has traveled a certain distance.

FIG. 4 is a diagram for explaining repetitive transmission / reception of stored information and final notification. In FIG. 4, G indicates the position of the own vehicle, H indicates the home, and B indicates the branch position where the position of the own vehicle deviates from the map-matched road for entering the home. Further, the point a located behind the own vehicle position G is the position where the "stored information" was transmitted last time in step 208 of FIG. 3, and the point b located in front of the own vehicle position is in step 208 of FIG. Indicates the position to send the "stored information" next time. Actually, the position of the own vehicle is the point b when a predetermined time has elapsed from the time when the "stored information" was transmitted last time, and when the point b is determined after a certain period of time has passed, the position of the own vehicle is at this point b. There must be a G, but for convenience of explanation, the points corresponding to the position of the own vehicle traveling every time a certain time arrives are indicated by b, c, d, ....

When the driver himself operates the vehicle along the road shown in FIG. 4 without using the guidance or automatic driving by the navigation device 200, at each of the points b, c, d, ... "Storage information" indicating whether or not high-precision map information corresponding to the driving road is stored is transmitted from the storage determination processing unit 340 of the high-precision map information management device 300 to the storage information acquisition processing unit 260 of the navigation device 200. NS. At the point b, whether or not the high-precision map information exists corresponding to the road from the point a to which the "stored information" was transmitted last time to the current point b (the high-precision map information corresponding to the high-precision map DB 310 is stored. For example, "stored information" indicating the ratio of the roads corresponding to the high-precision map information is created and transmitted. Similarly, similar "stored information" is created and transmitted at each of the points c, d, ... Up to the point i. At the branch position B, the position of the own vehicle deviates from the map-matched road, and an affirmative judgment is made in the determination in step 110 of FIG. The above-mentioned "stored information" is not transmitted or received.

In this way, the "stored information" transmitted and received at each point is stored (step 108 in FIG. 2), and when the ignition switch and the accessory switch are turned off in the parking lot of the home H, the automatic driving availability notification unit 270 will be notified. Each "stored information" transmitted, received, and stored corresponding to each point up to that point is aggregated, and a voice indicating the aggregated result (for example, a voice such as "The road on which the vehicle has traveled can be driven about 95% automatically"). Is output from the speaker 272.

As described above, in the in-vehicle system of the present embodiment, the driver himself / herself when he / she returns to his / her home and stops the vehicle after traveling on the road excluding the driving route for guiding the driving of the own vehicle and the automatic driving route. It is possible to know whether or not automatic driving is possible on a freely driven road.

In addition, in order to perform automatic driving, it is necessary to prepare high-precision map information for the road to be driven. Therefore, by checking the presence or absence of this high-precision map information, it is possible to determine whether or not automatic driving is possible. It becomes possible to know.

In addition, if the vehicle position cannot be corrected on the road by map matching, for example, if you are driving in a parking lot around your home or on a narrow street, you will not be subject to automatic driving like other roads in advance. Since it is known, the judgment accuracy can be improved by excluding it from the judgment target of the automatic operation.

In addition, when the operation is suddenly terminated due to a power off or the like by acquiring information indicating whether or not automatic operation is possible repeatedly at regular time intervals (“stored information” indicating whether or not high-precision map information is stored). However, it is possible to acquire and retain the information acquired up to that point each time.

In addition, by notifying when the ignition switch or accessory switch is turned off, notification is given when the engine is stopped and parking is performed, so whether or not automatic driving is possible while the memory of the route traveled up to that point is certain. Can be confirmed.

In addition, if you give a display notification after turning off the ignition switch or accessory switch, you may be worried that the power supply to the device that displays this display will not end, but there is such a concern about voice notification. Because there are few, it is possible to avoid unnecessarily anxious the driver.

In addition, the roads that the vehicle has passed through up to that point are notified including the percentage of sections that can be driven automatically. It is thought that the number of roads subject to autonomous driving will gradually increase, and it is not very likely at this point that 100% autonomous driving is possible on roads where drivers are free to drive, but autonomous driving is possible on such roads. It becomes possible to easily know the possible degree. In addition, when the degree to which automatic driving is possible is large, knowing it also has the effect of encouraging driving by automatic driving.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the gist of the present invention. For example, like the navigation device 200A shown in FIG. 5, a notification history storage unit 280 that stores the history of notifications by the automatic driving possibility notification unit 270 is added to the navigation device 200 shown in FIG. May suppress (do not perform notification) notifications that overlap with previously notified contents based on the history stored in the notification history storage unit 280. As a result, it is possible to improve the annoyance of being notified of the same content on the same road each time.

By the way, there are several conceivable methods for determining whether or not the content of the notification is duplicated. The simplest is the start point and end point of the route that the driver has freely traveled (for example, the start point at which the position of the vehicle is determined to be on the road in step 100 of FIG. 2 and the position of the vehicle from the road in step 110). (The end point is the point determined to be off), and if the start point and end point are the same, the notification may be suppressed. Further, in addition to these start points and end points, the passing roads between them may be stored, and the notification may be suppressed when the starting point, the ending point, and the passing roads are the same. Further, the start point may be the point where the ignition switch or the accessory switch is turned on, and the end point may be the point where these switches are turned off. In this case, for example, if the parking lot is large even if these switches are turned on / off in the parking lot of the same facility, the start point / end point may not be the same as the start point / end point of the history. If it is included in a range of about 10 m, it may be the same point, or if the map data contains polygon information indicating the facility shape, the range divided by this polygon may be the same point.

Further, in the above-described embodiment, a notification indicating whether or not automatic driving is possible on the road on which the driver has freely traveled is given, but this notification is the starting point of the route on which the driver has freely traveled. A travel route that can be automatically driven may be included, which is calculated by a route search process (for example, a route search process is performed by the path search processing unit 230 as a route search means) so as to connect between the end point and the end point. As a result, it is possible to notify the possibility of automatic driving on a freely driven road, propose an alternative route that can be automatically driven, and encourage the use of the automatic driving function by using the alternative route. It becomes.

Further, in the above-described embodiment, a notification is given indicating whether or not automatic driving is possible on the road (outward route) along the direction in which the driver freely travels, but the road is specified in this way. At the same time, it is possible to check whether automatic driving is possible for the return route (whether high-precision map information is stored), so it is necessary to notify whether automatic driving is possible for the outward route and the return route at the same time. May be good.

Further, in the above-described embodiment, the notification is always given in step 114 of FIG. 2, but a threshold value is set according to the degree to which automatic operation is possible, and the notification is given only when the threshold value is exceeded. It may be. For example, in the case of the threshold value "50%", the notification is given only when the ratio at which automatic operation is possible is more than 50%, and the notification is omitted when the ratio is 50% or less.

Further, in step 114 of FIG. 2, the notification is performed by utterance (voice output), but the display using the display unit 252 may be used in combination, or may be replaced with the notification by display instead. When giving a notification by display, it is desirable to include a display such as "The power will be automatically turned off after this notification" along with the content of the notification to eliminate the concern that the driver's energization will not end. ..

Further, in the above-described embodiment, the notification is given immediately after the timing of step 114 in FIG. 2, that is, immediately after the power is turned off (the ignition switch or the like is turned off), but the timing of giving the notification may be changed as appropriate. good. For example, the next time the power of the navigation device 200 is turned on, the notification may be given.

Further, in the above-described embodiment, when the position of the own vehicle deviates from the road, an affirmative judgment is made in the determination in step 110 of FIG. Since the position of the vehicle may be off the road in order to stop at a convenience store or restaurant, it is desirable not to make the above affirmative judgment when stopping at these facilities. For example, if the location of the vehicle off the road matches these facilities (the target facility or its genre may be specified in advance) (including the vicinity), the above affirmative judgment is not made. To do so. In addition, since the vehicle position may temporarily deviate from the road on the map when turning left or right at an intersection, the above affirmative judgment is made even if the vehicle position temporarily deviates from the road (for example, within 1 minute). It is desirable not to.

As described above, according to the present invention, the driver can know whether or not automatic driving is possible on the road on which he / she has freely traveled.
