  The present invention relates to an automatic driving availability notification system for notifying whether or not automatic driving is possible for a route on which a driver has traveled freely.

  Conventionally, when searching for a route from the departure point to the destination, the route that includes the road that cannot be automatically controlled with low position detection accuracy is avoided, and the shortest route that does not include the road that cannot be automatically controlled There is known a vehicle control apparatus that obtains the above (for example, see Patent Document 1). As a result, route guidance is performed so that the vehicle travels according to the searched route, and automatic control operation can be performed as necessary.

JP 2011-118603 A

  By the way, in the vehicle control device disclosed in Patent Document 1 described above, by finding 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. However, there is a problem that it is impossible to know whether or not roads that cannot be automatically controlled are included except for the route obtained by the search, that is, whether or not automatic controlled driving is possible.

  The present invention was created in view of the above points, and an object of the present invention is to provide an automatic driving availability notification system that allows a driver to know whether automatic driving is possible on a route that the driver has traveled freely. is there.

  In order to solve the above-described problems, the automatic driving availability notification system of the present invention is an automatic driving determination unit that repeatedly determines whether automatic driving is possible on a road on which the vehicle has passed, and a result of repeated determination by the automatic driving determination unit. An automatic driving determination result acquiring means for acquiring information indicating the information, and a notifying means for notifying information acquired by the automatic driving determination result acquiring means. Thus, the driver can know whether or not automatic driving is possible on the road on which he / she freely traveled.

  The vehicle further includes guide means for guiding the traveling of the host vehicle along the travel route to the destination, and the automatic driving determination means can determine whether automatic driving is possible when guidance by the guiding means is not performed. desirable. Alternatively, it further comprises automatic driving means for driving the vehicle along the driving route to the destination without the driver's driving operation, and the automatic driving determination means is when the vehicle is not driven by the automatic driving means, It is desirable to determine whether automatic driving is possible. When the vehicle travels on a road other than the travel route that guides the traveling of the host vehicle and the route of automatic driving, it can be known whether or not automatic driving is possible on this road.

  In addition, it is desirable that the above-described automatic driving determination means determines whether or not automatic driving is possible by examining the road on which the vehicle has passed for the presence or absence of high-precision map information necessary for performing automatic driving. In order to perform automatic driving, high-accuracy map information must be prepared for the road you are going to drive, so you can know whether automatic driving is possible by checking the presence of this high-accuracy map information. Is possible.

  A vehicle position detecting unit for detecting the vehicle position; and a vehicle position correcting unit for performing map matching for correcting the vehicle position detected by the vehicle position detecting unit to a position along a surrounding road. The automatic driving determination means preferably determines whether automatic driving is possible when the vehicle position is corrected on the road by map matching. As a result, when the vehicle position cannot be corrected on the road by map matching, for example, when driving in a parking lot around a home or on a narrow street, it may not be subject to automatic driving like other roads. Since it is known in advance, the determination accuracy can be improved by excluding it from the determination target of automatic driving.

  Moreover, it is desirable that the automatic driving determination result acquisition unit described above 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 power-off or the like, it is possible to acquire and hold the determination results so far 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 made when the engine is parked and the vehicle is parked. Therefore, it is possible to confirm whether automatic driving is possible while the memory of the route traveled so far is sure.

  Moreover, it is desirable that the notification means described above performs notification by voice. If notification is displayed after turning off the ignition switch or accessory switch, you may be worried that energization of the device that performs this display will not be terminated. Therefore, it is possible to avoid unnecessarily making the driver uneasy.

  In addition, the notification means described above, based on the information indicating the determination results of a plurality of times acquired by the automatic driving determination result acquisition means, a notification including the proportion of sections in which automatic driving can be performed on the road that the vehicle has passed so far. It is desirable to do. The number of roads subject to automatic driving is expected to increase gradually, and it is not very likely that 100% automatic driving is possible for roads where the driver freely travels. It is possible to easily know the possible extent. In addition, when the degree to which automatic driving is possible is large, knowing this also has an effect of promoting traveling by automatic driving.

  In addition, a notification history storage unit that stores a history of notifications by the above-described notification unit is further provided, and the notification unit is configured to notify a notification in the case of overlapping with previously notified content based on the history stored in the notification history storage unit. It is desirable to suppress. Thereby, the troublesomeness that the same content is notified about the same road every time can be improved.

  The automatic driving determination means further includes a route search means for setting a travel route that can be automatically driven between a start point and an end point of a series of repeated determinations by the route search processing, and the notification means is an automatic driving determination. It is desirable to notify the information acquired by the result acquisition means and propose the travel route set by the route search means. As a result, it is possible to know the alternative route that can be automatically driven, as well as whether or not automatic driving is possible for the road that has been freely traveled, and it is possible to promote traveling by automatic driving using the alternative route.

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

  FIG. 1 is a diagram illustrating a configuration of an in-vehicle system according to an embodiment. As shown in FIG. 1, the in-vehicle system of this 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 for driving the host vehicle along the driving route to the destination set by the navigation device 200 without the driver's driving operation. For example, in the present embodiment, level 3 or level 4 automatic driving is assumed. In addition, since a specific method for realizing automatic driving is not directly related to the contents of the present invention, the description thereof is omitted, but the present invention is applied to automatic driving using various technologies realized at present or in the future. be able to. Further, among the set travel routes, automatic driving is possible for roads (links) for which high-accuracy map information is prepared, and automatic driving is possible for the entire travel routes set by the navigation device 200. Not necessarily.

  The navigation device 200 performs a navigation operation for guiding the traveling of the vehicle (the host 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, a display unit 252, A stored information acquisition processing unit 260, an automatic driving availability notification unit 270, and a speaker 272 are provided. The navigation device 200 can be realized by executing a predetermined operation program using a CPU, ROM, RAM, etc., except for some components such as the GPS receiver 222, the display unit 252, and the speaker 272. .

  The map DB 210 displays a map image around the vehicle position, a route search operation for calculating an optimum travel route connecting the departure point and the destination, and the travel of the vehicle along the travel route obtained by the route search. Necessary for route guidance operation (guidance operation) for guiding the map data is stored. This map data is not required to be as accurate as the high-precision map information necessary for automatic driving. The map DB 210 stores map data in units of rectangular figure leaves divided into appropriate sizes by longitude and latitude. The map data of each leaf can be specified and read by designating the 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, and map data may be acquired from an external map distribution server (not shown).

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

  The route search processing unit 230 calculates a travel route having the lowest cost from the departure point to the destination by route search processing using the specified search condition.

  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 so as to be superimposed on the map image and displaying the guidance map of the right-left turn intersection. Then, an audio signal such as intersection guidance necessary for guiding the traveling of the vehicle along the traveling route is generated.

  The map display processing unit 250 draws a map image around the vehicle position, and superimposes the travel route drawn by the route guidance processing unit 240 and the left / right turn intersection guide map on the map image. To display.

  The storage information acquisition processing unit 260 requests the high-accuracy map information management device 300 to determine whether to store the high-accuracy map information when a predetermined condition is satisfied after the navigation apparatus 200 starts operating. In addition, the storage information acquisition processing unit 260 receives and stores “storage information” indicating whether or not the high-accuracy map information is repeatedly sent from the high-accuracy map information management device 300 in response to this request.

  The automatic driving propriety notifying unit 270 counts the “stored information” stored by the stored information acquisition processing unit 260 when the navigation apparatus 200 is powered off (for example, when an ignition switch or an accessory switch is turned off). Notify the driver. For example, an utterance process is performed in which the summary results are output as audio from the speaker 272. In the present embodiment, the navigation device 200 is assumed to end the operation at the time when this notification ends after the power-off instruction is given.

  The high-accuracy map information management device 300 stores the high-accuracy map information, and performs setting of an automatic driving route, storage judgment processing of the high-accuracy map information based on a request from the navigation device 200, and the like. For this purpose, the high-accuracy map information management device 300 includes a high-accuracy 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-accuracy map DB 310 stores high-accuracy map information that is high-accuracy map data necessary for automatic driving. All sections for expressways are scheduled to be created sequentially as needed for general roads, and versions of high-precision map information created at any point in time are stored in the high-precision map DB 310. To do. Similar to the map DB 210 provided in the navigation device 200, the high-accuracy map DB 310 is realized by a hard disk device or a semiconductor memory, or by a DVD and its reading device. Alternatively, the high-accuracy map DB 310 may be replaced with a communication device to acquire high-accuracy map information from an external map distribution server (not shown).

  The automatic driving route creation unit 320 extracts a section where automatic driving can be performed from the driving route to the destination set by the route search processing unit 230 of the navigation device 200, and specifically, the high-accuracy map information is obtained. An automatic driving route is created by extracting the corresponding section. Information on the created automatic driving route is sent to the automatic driving device 100. The automatic driving determination unit 330 determines whether the automatic driving device 100 is performing automatic driving.

  When the storage information acquisition processing unit 260 of the navigation device 200 requests storage determination, the storage determination processing unit 340 performs storage determination of high-accuracy map information corresponding to the road that is running, and the resulting high-accuracy map Information indicating whether information is stored is sent back to the stored information acquisition processing unit 260 at predetermined time intervals.

  The above-described storage determination processing unit 340 is an automatic driving determination unit, the stored information income processing unit 260 is an automatic driving determination result acquisition unit, the automatic driving availability notification unit 270 is a notification unit, the route guidance processing unit 240 is a guidance unit, The automatic driving device 100 corresponds to automatic driving means, the GPS receiver 222 corresponds to own vehicle position detection means, and the own vehicle position calculation unit 220 corresponds to own vehicle position correction 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 flowchart showing an operation procedure of the navigation device 200 that obtains the storage state of the high-precision map information and notifies the result while freely driving on an arbitrary road by the driver's own operation.

  The stored information acquisition processing unit 260 determines whether or not the own vehicle position matches the road (whether or not the own vehicle position has been corrected on the road by map matching by the own vehicle position calculation unit 220) (step 100). . For example, a negative determination is made when map matching is being performed immediately after leaving the home parking lot and the vehicle position is off the road on the map, and this determination is repeated. When the map matching is completed and the vehicle position is corrected and the vehicle is on the road on the map, an affirmative determination is made 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 determination 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-accuracy map information management apparatus 300 to determine whether to store the high-accuracy map information (Step 104). Thereafter, in response to this request, the storage information acquisition processing unit 260 determines whether or not “storage information” indicating whether or not the high-accuracy map information is stored is sent from the high-accuracy map information management device 300 (step 106). ). If it is sent, an affirmative determination is made, and the storage information acquisition processing unit 260 stores the received storage information (step 108).

  After this storage operation, or after the storage information is not sent from the high-precision map information management device 300 and a negative determination is made in the determination of step 106, the storage information acquisition processing unit 260 determines that the vehicle position is a road Whether or not the vehicle position has deviated from a 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 to start the guidance.

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

  When the power is turned off, an affirmative determination is made in the determination of step 112. Next, the automatic driving propriety notifying unit 270 performs an utterance process of outputting the result of summing up the “stored information” stored by the stored information acquisition processing unit 260 (step 114). In this way, a series of processing ends.

  FIG. 3 is a flowchart showing an operation procedure of storing determination of high-precision map information performed by the high-precision map information management apparatus 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, a negative determination is made and this determination is repeated.

  When a request for storage processing is received, an affirmative determination is made in the determination of step 200. Next, the automatic driving determination unit 330 determines whether or not automatic driving is in progress (step 202). In the case of automatic operation, an affirmative determination is made and the process is terminated.

  On the other hand, if the automatic operation is not being performed, a negative determination is made in the determination of step 202. Next, the storage determination processing unit 340 performs a storage determination process for high-accuracy map information corresponding to the traveling road (step 204). Specifically, the storage determination processing unit 340 determines whether or not there is high-precision map information for a road corresponding to the current vehicle position (the vehicle position is acquired from the vehicle position calculation unit 220 of the navigation device 200). It is checked whether or not high-accuracy map information corresponding to the road at the corresponding location is stored in the accuracy map DB 310).

  Thereafter, the storage determination processing unit 340 determines whether or not a predetermined time has elapsed (step 206). A negative determination is made until a predetermined time elapses, and the process returns to step 202 and the automatic driving determination is repeated. Further, when a certain time has elapsed, an affirmative determination is made in the determination of step 206. Next, the storage determination processing unit 340 transmits, to the storage information acquisition processing unit 260 of the navigation device 200, “storage information” indicating whether or not the high-accuracy map information is stored as a result of the storage determination processing until a predetermined time elapses. The data is transmitted (step 208). Thereafter, the process returns to step 202 and the automatic driving determination is repeated. In step 206 described above, it is determined whether or not a certain time has elapsed. Instead, it may be determined whether or not a certain distance has been traveled.

  FIG. 4 is a diagram for explaining the repeated transmission / reception of stored information and the last notification. In FIG. 4, G indicates the position of the own vehicle, H indicates the home, and B indicates a branch position where the position of the own vehicle deviates from the map-matched road to enter the home. Further, the point a located behind the vehicle position G is the position where the previous “stored information” was transmitted in step 208 in FIG. 3, and the point b located in front of the vehicle position is in step 208 in FIG. 3. The position where “storage information” is transmitted next time is shown. Actually, the vehicle position at the time when a predetermined time has elapsed since the last time when the “stored information” was transmitted is the point b, and when the point b is determined after a certain period of time, the vehicle position is at this point b. Although there must be G, for convenience of explanation, points corresponding to the own vehicle position that progresses every time a certain time comes are indicated by b, c, d,.

  When the driver 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 high-accuracy map information corresponding to the traveling road is stored is transmitted from the storage determination processing unit 340 of the high-accuracy map information management device 300 to the storage information acquisition processing unit 260 of the navigation device 200. The At the point b, whether or not there is high-precision map information corresponding to the road from the point a where 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, “storage information” indicating the ratio of roads corresponding to 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. Note that, at the branch position B, the vehicle position deviates from the map-matched road, and an affirmative determination is made in the determination of step 110 in FIG. The above-described “stored information” is not transmitted / received.

  Thus, the “stored information” transmitted / received at each point is stored (step 108 in FIG. 2), and when the ignition switch or the accessory switch is turned off in the parking lot at home H, the automatic driving availability notification unit 270 Each “stored information” that has been sent and received and stored in correspondence with each point up to that point is summed up, and a sound indicating the result of the summation (for example, a voice such as “The road you drove is capable of automatic driving about 95%”). Is output from the speaker 272.

  As described above, in the in-vehicle system of the present embodiment, when the driver travels on a road other than the travel route that guides the traveling of the vehicle and the route of the automatic driving and returns home to stop the car, It is possible to know whether or not automatic driving is possible on a freely traveling 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 existence of this high-precision map information, whether or not automatic driving is possible is determined. It becomes possible to know.

  In addition, when the vehicle position cannot be corrected on the road by map matching, for example, when driving in a parking lot around a home or on a narrow street, it may not be subject to automatic driving like other roads in advance. Since it is known, it is possible to improve the determination accuracy by excluding it from the determination target of automatic driving.

  In addition, by acquiring information indicating whether or not automatic driving can be repeated repeatedly at regular time intervals ("stored information" indicating whether high-precision map information is stored), the operation is suddenly terminated due to power-off or the like. However, it is possible to acquire and hold the information acquired until then each time.

  In addition, by notifying when the ignition switch or accessory switch is turned off, notification is given when parking with the engine stopped. Can be confirmed.

  In addition, if the display notification is performed after turning off the ignition switch or accessory switch, there may be a concern that energization of the device that performs the display will not be terminated. Therefore, it is possible to avoid unnecessarily making the driver uneasy.

  In addition, notifications including the proportion of sections where automatic driving can be performed are given for roads through which the vehicle has passed. The number of roads subject to automatic driving is expected to increase gradually, and it is not very likely that 100% automatic driving is possible for roads where the driver freely travels. It is possible to easily know the possible extent. In addition, when the degree to which automatic driving is possible is large, knowing this also has an effect of promoting traveling by automatic driving.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, like the navigation device 200A shown in FIG. 5, a notification history storage unit 280 that stores the history of notification by the automatic driving availability notification unit 270 is added to the navigation device 200 shown in FIG. May suppress notifications that do not overlap with previously notified contents based on the history stored in the notification history storage unit 280 (not notified). Thereby, the troublesomeness that the same content is notified about the same road every time can be improved.

  By the way, several methods can be considered as a method for determining whether or not the contents of the notification overlap. In the simplest case, the starting point and the ending point of the route on which the driver travels freely (for example, the starting point is the point where the vehicle position is determined to be on the road in step 100 in FIG. It is conceivable that notification is suppressed when the start point and the end point are the same. Further, in addition to the start point and the end point, a passing road between them may be stored, and notification may be suppressed when the start point, the end point, and the passing road are the same. Also, the start point may be a point where an ignition switch or an accessory switch is turned on, and the end point may be a 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. The case of being included in a range of about 10 m may be the same point, or if the map data includes polygon information indicating the facility shape, the same point may be used for the range defined by this polygon.

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

  In the above-described embodiment, a notification indicating whether or not automatic driving is possible for a road (outbound path) along the direction in which the driver has traveled freely is performed. In this way, the road is identified. For example, it is possible to check whether automatic driving is possible on the return path at the same time (whether high-precision map information is stored). Also good.

  Further, in the above-described embodiment, the notification is always performed in step 114 of FIG. 2, but a threshold is provided depending on the extent that automatic driving is possible, and notification is performed only when this threshold is exceeded. It may be. For example, in the case of the threshold value “50%”, the notification is performed only when the rate at which automatic driving is possible is greater than 50%, and the notification is omitted when it is 50% or less.

  Further, in step 114 of FIG. 2, notification is performed by utterance (speech output). However, display using the display unit 252 may be used together, or instead may be replaced with notification by display. When notification by display is included, it is desirable to remove the concern that the driver will not end the energization by including a display such as “The power will be automatically turned off after this notification” along with the notification content. .

  In the above-described embodiment, the notification is performed immediately after the timing of step 114 in FIG. 2, that is, immediately after the power is turned off (the ignition switch and the like are turned off). However, the timing for performing the notification may be changed as appropriate. Good. For example, the notification may be performed when the navigation device 200 is turned on next time.

  In the above-described embodiment, when the vehicle position deviates from the road, an affirmative determination is made in the determination of step 110 in FIG. 2 and the operation proceeds to the next step 112. In some cases, the location of the vehicle may deviate from the road in order to stop at convenience stores, restaurants, etc., so it is desirable not to make the affirmative judgment when stopping at these facilities. For example, if the location where the vehicle is off the road matches these facilities (the target facility or its genre may be specified in advance) (including the vicinity), the above positive determination is not performed. Like that. In addition, since the vehicle position may temporarily deviate from the road on the map when turning left or right at the intersection, the above determination is made even if the vehicle position temporarily deviates from the road (for example, within 1 minute). Desirably not.

  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 freely traveled.
