Description

  The present invention relates to a reprogramming control device.

  Conventionally, a technique for permitting reprogramming of a device mounted on a vehicle when a predetermined condition is satisfied is known (see, for example, Patent Document 1). The technology of Patent Document 1 determines whether or not the vehicle is parked in a safe place, and when it is determined that the vehicle is parked in a safe place, the program of the control device mounted on the vehicle is updated. Is allowed.

JP 2010-243339 A

  However, in the conventional technique, when it is determined that the vehicle is parked in a safe place, reprogramming of the device mounted on the vehicle starts. Therefore, there may be a case where the reprogramming is not finished before the vehicle is started from the parking place where the reprogramming is performed.

  In view of this, an object of one aspect of the present disclosure is to provide a reprogramming control device that can reduce the possibility that reprogramming has not ended before the vehicle is started from a parking position.

In order to achieve the above object, according to one aspect of the present disclosure,
A position information acquisition unit for acquiring position information of the vehicle;
A determination unit for determining whether it is possible to perform reprogramming of the device mounted on the vehicle at a vehicle position indicated by the position information acquired by the position information acquisition unit;
A signal output unit that outputs a signal indicating that the reprogramming cannot be performed when the reproducibility determination unit determines that the reprogramming cannot be performed at the vehicle position;
A parking time acquisition unit that acquires a predicted parking time that is a predicted value of the time at which the vehicle is parked at the vehicle position;
A required time acquisition unit for acquiring the required time for reprogramming,
The availability determination unit determines that the reprogramming is impossible when the estimated parking time acquired by the parking time acquisition unit is shorter than the required time acquired by the required time acquisition unit. A reprogramming controller is provided.

  According to this reprogramming control device, when the estimated parking time acquired by the parking time acquisition unit is shorter than the required time acquired by the required time acquisition unit, it is impossible to perform the reprogramming. Is determined by the availability determination unit. When the availability determination unit determines that the reprogramming cannot be performed, a signal indicating that the reprogramming cannot be performed is output.

  When the predicted parking time is shorter than the time required for reprogramming, the timing at which the reprogramming ends may exceed the timing at which the vehicle is predicted to start from the parking position. In this regard, according to the reprogramming control device described above, when the estimated parking time is shorter than the time required for the reprogramming, a signal indicating that the reprogramming cannot be performed is output. As described above, when the estimated parking time is shorter than the time required for the reprogramming, a signal indicating that the reprogramming cannot be performed is output. Therefore, until the vehicle is started from the parking position. The possibility that reprogramming is not over can be reduced.

  According to one aspect of the present disclosure, it is possible to reduce the possibility that reprogramming has not ended before the vehicle is started from the parking position.

The gateway 130 relays information collected from each device to the communication device 120 and relays information received by the communication device 120 to each device (for example, the repro target device 190 and the user confirmation unit 112).

  The gateway 130 includes an OTA repro permission determination information collection unit 131. Hereinafter, the OTA repro permission determination information collection unit 131 may be simply referred to as a “collection unit 131”. The collection unit 131 collects availability determination information used for determining whether to perform OTA repro from each device. For example, the collection unit 131 collects availability determination information used to determine whether or not the vehicle 10 is parked at an appropriate place for performing OTA repro, and the collected availability determination information is transmitted via the communication device 120.

For example, the position detection unit 111 detects GPS coordinates representing the current position of the vehicle 10 based on the GPS signal from the GPS satellite 20. For example, the position detection unit 111 estimates beacon coordinates representing the current position of the vehicle 10 based on the radio wave intensity from the beacon 30. For example, the position detection unit 111 detects the Wi-Fi address and the radio wave status of the Wi-Fi access point 40 based on a signal from the Wi-Fi access point 40.

Notifying the user of the time required for repro helps the user to determine whether or not to perform OTA repro.

  In addition, the user confirmation unit 112 notifies the user of the determination result of whether or not OTA repro can be performed (the determination result of whether or not the OTA repro is performed by the reprogramming control device 200 on the center 50 side). If it is not possible to determine whether or not to perform OTA repro, the user confirmation unit 112 reconfirms with the user of the vehicle 10 whether or not to perform OTA repro.

The vehicle periphery information is included in information for specifying the position of the vehicle 10 (position information of the vehicle 10).

  When the collection unit 141 receives the vehicle surrounding information collection request transmitted from the collection unit 131, the collection unit 141 uses the object detection sensor 142 that detects an object around the vehicle 10, and the size of the surrounding object existing around the vehicle 10. Object detection information such as the distance to the surrounding object and the direction in which the surrounding object exists is detected. In addition, when the collection unit 141 receives the vehicle periphery information collection request transmitted from the collection unit 131, the collection unit 141 uses the periphery monitoring camera 143 that captures the periphery of the vehicle 10 to obtain image information around the vehicle 10 in the parked state.

  The communication device 120 is an example of an electronic control device that converts a communication protocol between a wired communication network inside the vehicle 10 and a wireless communication network outside the vehicle 10. The communication device 120 wirelessly transmits the above-described various availability determination information collected from each device by the collection unit 131 to the reprogramming control device 200 on the center 50 side. The communication device 120 wirelessly receives the determination result of whether or not to perform the OTA repro (OTA repro permission determination result) from the reprogramming control device 200 and provides the OTA repro permission determination result to the collection unit 131 of the gateway 130.

  Next, a flow of information collection processing executed by the collection unit 131 on the vehicle 10 side will be described.

  FIG. 2 is a flowchart illustrating an example of a flow of information collection processing executed by the collection unit 131.

  In step S110, the collection unit 131 determines whether downloading of the OTA repro data is completed by the communication device 120 and the vehicle 10 is parked.

  The OTA repro data is a program that is a target of OTA repro and represents a rewriting program that is written in the storage device of the repro target device 190. The OTA repro data is transmitted wirelessly from an external facility (the center 50 or a facility other than the center 50) located remotely from the vehicle 10.

  For example, when the parking brake information acquired from the body ECU 170 indicates that the collecting unit 131 is operating, the collecting unit 131 determines that the vehicle 10 is parked.

  When the collection unit 131 determines that the download of the OTA repro data is completed by the communication device 120 and the vehicle 10 is parked, the collection unit 131 performs the process of step S120. On the other hand, when it is determined that the download of the OTA repro data is not completed by the communication device 120 or the vehicle 10 is not parked, the collection unit 131 ends the information collection processing without executing the processing of step S120. Let

  In step S120, the collection unit 131 causes the user confirmation unit 112 to perform user confirmation as to whether or not repro is performed. The collection unit 131 acquires from the user confirmation unit 112 the result of determining whether or not to perform OTA repro. When the collection unit 131 acquires a user confirmation result that allows OTA repro to be performed, the collection unit 131 performs the process of step S130. On the other hand, when the collection unit 131 obtains a user confirmation result that disables OTA repro, the collection unit 131 ends the information collection process.

  In step S <b> 130, the collection unit 131 acquires information for specifying the position of the vehicle 10 (position information of the vehicle 10). For example, the collection unit 131 acquires GPS coordinates, beacon coordinates, Wi-Fi addresses, and radio wave conditions from the position detection unit 111. For example, the collection unit 131 acquires vehicle peripheral information such as image information and object detection information from the collection unit 141.

  In step S140, the collection unit 131 acquires a vehicle state necessary for determining whether or not to perform OTA repro. This vehicle state is an example of the propriety determination information used for determining the propriety of performing the OTA repro. For example, the collection unit 131 acquires a vehicle state used for determining whether to continue parking, such as vehicle speed information, shift position information, and automatic parking presence / absence information.

  In Step S150, collection part 131 acquires parking prediction time. For example, the collection unit 131 acquires a user repro designated time zone that is an example of a predicted parking time from the user confirmation unit 112. For example, the collection unit 131 acquires a learned parking prediction time that is an example of a parking prediction time from the learning unit 151. For example, the collection unit 131 acquires an elapsed parking time (current parking time) from the start of parking.

  In step S160, the collection unit 131 packs the information acquired from each device as shown in FIG. 3, and uses the packed information (that is, the determination information for determining whether to perform OTA repro). The communication device 120 is wirelessly transmitted. FIG. 3 is a diagram illustrating an example of packing for determining whether or not OTA repro can be performed.

  Next, an example of the configuration on the center 50 side will be described.

  In FIG. 1, the center 50 is an example of a facility located remotely from the vehicle 10. The center 50 includes a reprogramming control device 200, a user parking position information DB (Data Base) 60, and an OTA repro availability determination DB 70. The center 50 may be a facility that is divided into a plurality of locations. That is, the reprogramming control device 200, the user parking position information DB 60, and the OTA repro permission / inhibition determination DB 70 may be divided into a plurality of places.

  The reprogramming control device 200 includes a position information acquisition unit 210, a repro availability determination unit 220, a signal output unit 230, a parking time acquisition unit 240, and a repro required time acquisition unit 250.

  The position information acquisition unit 210 is an example of a position information acquisition unit that acquires position information of the vehicle 10. The position information acquisition unit 210 acquires the position information of the vehicle 10 from the communication device 120 on the vehicle 10 side. The position information of the vehicle 10 includes, for example, map position information such as GPS coordinates, vehicle periphery information such as a peripheral camera image and a plurality of target detection information.

  The repro availability determination unit 220 is an example of an availability determination unit that determines whether it is possible to perform reprogramming of the device mounted on the vehicle 10 at the vehicle position indicated by the position information acquired by the position information acquisition unit 210. The repro permission / prohibition determination unit 220 acquires from the communication device 120 permission determination information used to determine whether or not to perform OTA repro. The repro permission / prohibition determination unit 220 compares the reproducibility determination information acquired from the communication device 120 with the permission determination criterion information stored in advance in the OTA repro permission determination DB 70, thereby performing reprogramming of the repro target device 190 at the vehicle position. Judge whether or not to do it. Details of a method for determining whether reprogramming can be performed at the vehicle position will be described later.

  The signal output unit 230 is an example of a signal output unit that outputs a signal indicating that reprogramming is not possible when the reprogramming determination unit 220 determines that reprogramming is impossible. is there. The signal output unit 230 wirelessly transmits a signal indicating that the reprogramming target device 190 cannot be reprogrammed to the communication device 120. As a specific example of a signal indicating that reprogramming cannot be performed, a signal indicating that the user of the vehicle 10 is notified of the failure of reprogramming via the user confirmation unit 112, a collection unit that performs reprogramming For example, a signal indicating prohibition by 131 is given.

  The signal output unit 230 outputs a signal indicating that the reprogramming may be performed when the reproprovisioning determination unit 220 determines that the reprogramming target device 190 can be reprogrammed. For example, the signal output unit 230 wirelessly transmits a permission signal that permits reprogramming of the repro target device 190 to the communication device 120.

  The parking time acquisition unit 240 is an example of a parking time acquisition unit that acquires a predicted parking time that is a predicted value of the time at which the vehicle 10 is parked at the vehicle position indicated by the position information acquired by the position information acquisition unit 210. The parking time acquisition unit 240 acquires information about the predicted parking time of the vehicle 10 (for example, the user repro designated time zone and the length thereof, the learned parking predicted time, etc.) from the communication device 120.

  The repro required time acquisition unit 250 is an example of a required time acquisition unit that acquires the time required for reprogramming of the repro target device 190. The repro required time acquisition unit 250 acquires the reprogramming time required for the repro target device 190 from the repro data management server that manages the OTA repro data. The installation location of the repro data management server may be the center 50 or a facility other than the center 50.

  The reprogramming control device 200 includes a processor such as a CPU, a ROM, and a RAM. The functions of the position information acquisition unit 210, the repro permission determination unit 220, the signal output unit 230, the parking time acquisition unit 240, and the repro required time acquisition unit 250 are realized by the processor executing a program stored in the ROM. The program includes a program that causes a processor to execute a processing procedure for realizing a function. The RAM stores various types of data including intermediate data for operations performed by programs executed by the processor.

  Next, the flow of processing executed by the reprogramming control device 200 on the center 50 side will be described.

  FIG. 4 is a flowchart illustrating an example of a flow of processing executed by the reprogramming control device 200.

  In step S210, the repro availability determination unit 220 receives the availability determination information used for determining whether or not to perform the OTA repro from the communication device 120, and in step S220, the current parking position of the vehicle 10 is changed to the OTA repro. Determine if it is the right place.

  In step S <b> 220, the repro permission determination unit 220 performs the position determination process A shown in FIG. 5 based on the position information of the vehicle 10 (see FIG. 3) included in the permission determination information acquired from the communication device 120. . Alternatively, in step S <b> 220, the repro permission / prohibition determination unit 220 performs the position determination process illustrated in FIGS. A to E are performed in combination. When the position determination processes A to E are performed in combination, the position determination process A has the highest processing priority. In step S220, repro permission / inhibition determination section 220 performs the parking determination process shown in FIG. 11 based on the vehicle state (see FIG. 3) included in the permission determination information received from communication device 120.

  FIG. 5 is a flowchart illustrating an example of the flow of the position determination process A.

  In step S300, the repro permission / prohibition determination unit 220 includes the position information (own vehicle position information) of the vehicle 10 acquired by the position information acquisition unit 210 and the user parking position information registered in advance in the user parking position information DB 60. Determine whether they match.

  As specific examples of the user parking position information, coordinate information of a place (parking designated place) designated in advance by the user as a parking position of the vehicle 10 or a surrounding image, coordinate information of a target (target) existing around the designated parking place Or an image, Wi-Fi information of a parking designated place, etc. are mentioned. As a specific example of the parking designated place, a home parking lot of the user of the vehicle 10 can be cited. A specific example of a target existing around a designated parking place is a wall of a home parking lot.

  When the repro availability determination unit 220 determines in step S300 that the own vehicle position information and the user parking position information match, the own vehicle position indicated by the position information acquired by the position information acquisition unit 210 is appropriate for the OTA repro. The location is determined (step S310). On the other hand, when determining that the own vehicle position information and the user parking position information do not match in step S300, the repro availability determination unit 220 determines that the own vehicle position indicated by the position information acquired by the position information acquisition unit 210 is the OTA repro It is determined that the location is inappropriate (step S320). Alternatively, when determining that the own vehicle position information does not match the user parking position information in step S300, the repro availability determination unit 220 cannot determine whether or not the own vehicle position is a suitable place for OTA repro ( Step S320). For example, the repro availability determination unit 220 executes the position determination process B of FIG. 7 in order to leave the determination to another position determination process when the determination is impossible in step S320.

  FIG. 6 is a diagram illustrating an example of a situation where a position determination process A in which a vehicle target and Wi-Fi information are combined is performed. It is difficult to specify the position of the vehicle 10 only with the signal from the Wi-Fi access point 40. However, the combined use of the in-vehicle sensor improves the accuracy of determining whether or not the vehicle is parked at the designated parking place.

  For example, since the position detection unit 111 of the vehicle 10B can receive a signal from the Wi-Fi access point 40, the collection unit 131 of the vehicle 10B can collect the Wi-Fi address and the radio wave status of the Wi-Fi access point 40. . However, the collection unit 131 of the vehicle 10B cannot acquire the vehicle periphery information from the periphery monitoring ECU 140.

  On the other hand, since the position detection unit 111 of the vehicle 10A can receive a signal from the Wi-Fi access point 40, the collection unit 131 of the vehicle 10A can collect the Wi-Fi address and the radio wave status of the Wi-Fi access point 40. . The collection unit 131 of the vehicle 10 </ b> A can collect vehicle periphery information about the rear and left walls of the vehicle 10 </ b> A from the periphery monitoring ECU 140. Therefore, when the vehicle periphery information about the rear and left walls of the vehicle 10A is registered in advance in the user parking position information DB 60, the repro availability determination unit 220 determines that the own vehicle position information and the user parking position information match. This can be determined in step S300.

  FIG. 7 is a flowchart illustrating an example of the flow of the position determination process B.

  In step S <b> 400, repro propriety determination unit 220 determines whether vehicle 10 is parked using the automatic parking function based on the automatic parking presence / absence information acquired from communication device 120.

  When determining that the vehicle 10 is parked using the automatic parking function in step S400, the repro availability determination unit 220 determines that the vehicle position indicated by the position information acquired by the position information acquisition unit 210 is the OTA repro. It is determined that the place is appropriate (step S410). On the other hand, if the repro availability determination unit 220 determines in step S400 that the vehicle 10 is not parked using the automatic parking function, the vehicle position indicated by the position information acquired by the position information acquisition unit 210 is OTA. It is impossible to determine whether or not the place is suitable for repro (step S420). For example, the repro permission / prohibition determination unit 220 executes the position determination process C in FIG. 8 in order to leave the determination to another position determination process when the determination is impossible in step S420.

  FIG. 8 is a flowchart illustrating an example of the flow of the position determination process C.

  In step S <b> 500, the repro propriety determination unit 220 includes the own vehicle position coordinates included in the position information of the vehicle 10 acquired by the position information acquisition unit 210, and the OTA repro permission coordinates registered in advance in the OTA repro propriety determination DB 70. It is judged whether or not. Alternatively, the repro propriety determination unit 220 matches the own vehicle position coordinates included in the position information of the vehicle 10 acquired by the position information acquisition unit 210 with the OTA repro prohibition coordinates registered in advance in the OTA repro propriety determination DB 70. It may be determined whether or not to do so.

  The OTA repro permission coordinates and the OTA repro permission coordinates serve as a reference for determining whether or not reprogramming of the device mounted on the vehicle 10 can be performed at the vehicle position indicated by the position information acquired by the position information acquisition unit 210. It is an example of the determination criteria information.

  Specific examples of the OTA repro-permitted coordinates include a parking lot position coordinate and a Wi-Fi access point 40 position coordinate. Specific examples of the OTA repro-rejected coordinates include a road position coordinate and a position coordinate of a place designated in advance by the user as a place where repro is impossible.

  When determining that the vehicle position coordinates coincide with the OTA repro permission coordinates, the repro availability determination unit 220 determines that the vehicle position indicated by the position information acquired by the position information acquisition unit 210 is appropriate for the OTA repro. It is determined that it is a place (step S520). On the other hand, when determining that the vehicle position coordinates do not match the OTA repro permission coordinates in step S500, the repro availability determination unit 220 determines that the vehicle position indicated by the position information acquired by the position information acquisition unit 210 is the OTA repro It is determined that the location is inappropriate (step S510). On the other hand, if it is not possible to determine whether or not the vehicle position coordinates match the OTA repro permission coordinates, the repro availability determination unit 220 determines that the vehicle position indicated by the position information acquired by the position information acquisition unit 210 is OTA. It is impossible to determine whether or not the place is suitable for repro (step S530). For example, the repro permission / prohibition determination unit 220 executes the position determination process D of FIG. 9 in order to leave the determination to other position determination processes when the determination is impossible in step S530.

  FIG. 9 is a flowchart illustrating an example of the flow of the position determination process D.

  In step S600, the repro permission / prohibition determination unit 220 includes the own vehicle camera image included in the position information of the vehicle 10 acquired by the position information acquisition unit 210 and the OTA repro prohibition place image registered in advance in the OTA repro permission determination DB 70. Whether or not matches is determined.

  Specific examples of the OTA repro-prohibited place image include a road white line image, a traffic light image, and a road sign image. The OTA repro-prohibited place image is information on whether or not the re-programming of the device mounted on the vehicle 10 is a criterion for determining whether or not the vehicle position indicated by the position information acquired by the position information acquiring unit 210 can be performed. It is an example.

  If the repro availability determination unit 220 determines in step S600 that the vehicle camera image matches the OTA repro prohibited place image, the vehicle position indicated by the position information acquired by the position information acquisition unit 210 is not recognized by OTA repro. It is determined that the place is appropriate (step S610). On the other hand, if the repro availability determination unit 220 determines in step S600 that the vehicle camera image does not match the OTA repro-prohibited place image, the vehicle position indicated by the position information acquired by the position information acquisition unit 210 is OTA. It is determined that the place is suitable for repro (step S620). On the other hand, if it is not possible to determine whether or not the own camera image matches the OTA repro-prohibited place image, the repro availability determination unit 220 determines that the own vehicle position indicated by the position information acquired by the position information acquisition unit 210 is It is impossible to determine whether or not the place is suitable for the OTA repro (step S630). For example, the repro permission / prohibition determination unit 220 executes the position determination process E in FIG. 10 in order to leave the determination to another position determination process when the determination is impossible in step S630.

  FIG. 10 is a flowchart illustrating an example of the flow of the position determination process E.

  In step S <b> 700, the repro permission determination unit 220 determines beacon information (specifically, beacon coordinates) included in the position information of the vehicle 10 acquired by the position information acquisition unit 210 and the position coordinates of the prescribed parking prohibited place. Whether or not matches is determined.

  If the repro availability determination unit 220 determines in step S700 that the beacon coordinates match the position coordinates of the prescribed parking prohibited place, the vehicle position indicated by the position information acquired by the position information acquisition unit 210 is changed to the OTA repro. It is determined that the location is inappropriate (step S710). On the other hand, if the beacon coordinates do not match the position coordinates of the prescribed parking prohibited place but the position coordinates of the prescribed parking permitted place coincide with the position coordinates of the prescribed parking permitted place, the repro availability determination unit 220 obtains the position information obtaining unit 210. It is determined that the vehicle position indicated by the position information is an appropriate place for the OTA repro (step S720). On the other hand, if the repro availability determination unit 220 cannot determine whether the beacon coordinates match the position coordinates of the prescribed parking prohibited place, the vehicle position indicated by the position information acquired by the position information acquisition unit 210 It is impossible to determine whether or not is a place suitable for OTA repro (step S730).

  FIG. 11 is a flowchart illustrating an example of the flow of the parking determination process.

  In step S800, repro permission determination unit 220 determines whether vehicle 10 is in a locked state based on the vehicle state (see FIG. 3) included in the permission determination information received from communication device 120. The locked state refers to a state where the parking brake device is braking the vehicle 10. For example, when the shift position information indicates the parking position, the vehicle speed information indicates zero, and the parking brake information indicates that the brake is operating, the repro propriety determination unit 220 determines that the vehicle 10 is in the locked state.

  When determining that the vehicle 10 is not in the locked state, the repro availability determination unit 220 determines that the vehicle 10 is in a state other than the parking state (step S830). On the other hand, if the repro availability determination unit 220 determines that the vehicle 10 is in the locked state, it executes the process of step S810.

  In step S810, if the locked state continues for a predetermined time (for example, 5 minutes) or there is parking confirmation information by the user, the repro permission / inhibition determining unit 220 determines that the vehicle 10 is in a parked state (step S820). The parking confirmation information by the user is included in the availability determination information received from the communication device 120 and is acquired from the user confirmation unit 112. On the other hand, if the locked state is less than the predetermined time and there is no parking confirmation information by the user, the repro availability determination unit 220 determines that the vehicle 10 is in a state other than the parking state (step S830).

  Returning to FIG. 4, in step S <b> 220, the repro permission determination unit 220 determines the vehicle 10 based on the processing results of the position determination process A (or the combination process of the position determination processes A to E) and the parking determination process. Determine whether the current parking position is appropriate for OTA Repro.

  When determining that the current parking position of the vehicle 10 is an appropriate place for the OTA repro, the repro availability determination unit 220 executes the process of step S230. On the other hand, if the repro availability determination unit 220 determines that the current parking position of the vehicle 10 is an inappropriate place for the OTA repro, it determines that it is impossible to perform the OTA repro at the current parking position of the vehicle 10. (Step S240). On the other hand, if the repro availability determination unit 220 cannot determine whether the current parking position of the vehicle 10 is a suitable place for the OTA repro, it can determine whether or not the OTA repro can be performed at the current parking position of the vehicle 10. Therefore, it is determined that determination by the user is necessary (step S260).

  In step S <b> 230, the repro availability determination unit 220 determines that the OTA repro time (reprogramming time for the repro target device 190) acquired by the repro required time acquisition unit 250 is acquired by the parking time acquisition unit 240. Judge whether it is shorter than the time. In order to determine whether the OTA repro time is shorter than the estimated parking time, the repro availability determination unit 220 performs a combination of the time determination processes A and B shown in FIGS. Regarding the processing priority, the time determination processing A is higher than the time determination processing B.

  FIG. 12 is a flowchart illustrating an example of the flow of the time determination process A.

  In step S900, repro permission determination unit 220 determines whether the time obtained by adding the OTA repro time to the current time is within the user repro designated time zone. When the time obtained by adding the OTA repro time to the current time is within the user repro designated time zone, the OTA repro time is shorter than the length of the user repro designated time zone. Therefore, if the repro availability determination unit 220 determines that the time obtained by adding the OTA repro time to the current time is within the user repro designated time zone, it determines that the OTA repro is completed within the predicted parking time (step S910). On the other hand, if the repro availability determination unit 220 determines that the time obtained by adding the OTA repro time to the current time is not within the user repro designated time zone, it determines that the OTA repro is not completed within the predicted parking time (step S920). .

  FIG. 13 is a flowchart illustrating an example of the flow of the time determination process B.

  In step S1000, repro feasibility determining unit 220 determines whether or not the OTA repro time is shorter than the predicted learning parking time. When determining that the OTA repro time is shorter than the learned parking prediction time (see FIG. 14), the repro availability determination unit 220 determines that the OTA repro is completed within the predicted parking time (step S1010). On the other hand, if the repro availability determination unit 220 determines that the OTA repro time is not shorter than the learned parking prediction time, it determines that the OTA repro is not completed within the predicted parking time (step S1020).

  FIG. 14 is a diagram illustrating an example of a situation in which the time determination process B is performed. FIG. 14 shows a case where the OTA repro time is shorter than the estimated parking time, and in this case, the estimated parking time is the length of the time zone from 2 o'clock to 7 o'clock. FIG. 14 shows that the time (OTA repro completion expected time) obtained by adding the OTA repro time to the current time (OTA repro start time) is within that time zone. Since 7:00 is the time at which the time zone (traveling time zone) in which the vehicle 10 is used on weekdays is predicted to start from the usage history, the predicted learning parking time is the time up to 7 o'clock.

  Therefore, when the repro availability determination unit 220 determines that the OTA repro is completed within the estimated parking time (when at least one of steps S910 and S1010 is established), the repro can be performed at the current parking position of the vehicle 10. It is determined that it is possible (step S250 in FIG. 4). On the other hand, when it is determined that the OTA repro is not completed within the estimated parking time (when both steps S920 and S1020 are established), the repro availability determination unit 220 can perform the OTA repro at the current parking position of the vehicle 10. It is determined that it is impossible (step S240 in FIG. 4).

  In step S270 of FIG. 4, the signal output unit 230 transmits the determination results of steps S240, S250, and S260 toward the vehicle 10.

  For example, when the signal output unit 230 determines that it is impossible to perform OTA repro at the current parking position of the vehicle 10 (step S240), the signal output unit 230 notifies the user of the vehicle 10 via the user confirmation unit 112 that the reprogramming is impossible. To output a signal indicating notification. Thereby, the user confirmation unit 112 notifies the user of the vehicle 10 that reprogramming is impossible based on the signal received by the communication device 120. As a result, since the user can recognize that reprogramming is impossible, the possibility of the user performing reprogramming is reduced. Therefore, it is possible to reduce the possibility that the reprogramming is performed even when the estimated parking time is a short time required for the reprogramming and the reprogramming is not finished before the vehicle is started from the parking position.

  For example, when the signal output unit 230 determines that it is impossible to perform OTA repro at the current parking position of the vehicle 10 (step S240), the signal output unit 230 prohibits the collection unit 131 from performing reprogramming. Output a signal that represents Accordingly, the collection unit 131 prohibits reprogramming of the repro target device 190 based on the signal received by the communication device 120. Therefore, reprogramming of the repro target device 190 is not performed. Therefore, it is possible to reduce the possibility that the reprogramming is performed even when the estimated parking time is a short time required for the reprogramming and the reprogramming is not finished before the vehicle is started from the parking position.

  On the other hand, for example, when the signal output unit 230 determines that the OTA repro can be performed at the current parking position of the vehicle 10 (step S250), the user confirmation unit 112 notifies the user of the vehicle 10 that reprogramming is possible. A signal indicating that notification is to be made is output. As a result, the user confirmation unit 112 notifies the user of the vehicle 10 that reprogramming is possible based on the signal received by the communication device 120. Therefore, the user can recognize that reprogramming can be performed.

  For example, when the signal output unit 230 determines that the OTA repro can be performed at the current parking position of the vehicle 10 (step S250), the permission signal that permits the collection unit 131 to perform reprogramming. Is output. Accordingly, the collection unit 131 permits reprogramming of the repro target device 190 based on the signal received by the communication device 120. Therefore, reprogramming of the repro target device 190 is performed.

<Second Embodiment>
Next, a second embodiment will be described. In places where wireless communication is not possible (for example, underground parking lots), the communication device 120 cannot download OTA repro data from an external facility. In such a place, the center 50 cannot determine whether or not OTA repro can be performed.

  Therefore, in order to solve such a problem, in the second embodiment, the state of the underground parking lot is acquired on the vehicle 10 side, and whether or not the OTA repro can be performed is determined on the center 50 side while the vehicle 10 is traveling on the ground. Get in. The configuration of the second embodiment uses the configuration of the first embodiment shown in FIG.

  The collection unit 131 of the gateway 130 acquires in advance vehicle surrounding information including a camera image of the underground parking lot and target information from the collection unit 141 of the periphery monitoring ECU 140. The communicator 120 uploads the vehicle peripheral information acquired in advance by the collection unit 131 to the reprogramming control device 200 of the center 50 by OTA while traveling on the ground where wireless communication is possible. The reprogramming determination unit 220 of the reprogramming control device 200 determines whether or not OTA repro can be performed by pattern matching using the vehicle periphery information.

  When it is determined that the OTA repro can be performed, the signal output unit 230 wirelessly transmits a permission signal that permits reprogramming of the repro target device 190 to the communication device 120. Based on the signal received by the communication device 120, the collection unit 131 stores the same information as the vehicle periphery information that has been uploaded earlier by OTA.

  After that, when performing the repro of the repro target device 190, the collection unit 131 compares the vehicle periphery information stored in advance with the current vehicle periphery information acquired from the periphery monitoring ECU 140 using pattern matching or the like. When the comparison results match, the collection unit 131 starts reproposing the repro target device 190.

  Therefore, repro can be implemented even in places where wireless communication is not possible (for example, underground parking lots).

<Third Embodiment>
Next, a third embodiment will be described.

  FIG. 15 is a diagram illustrating an example of a configuration of a reprogramming control system according to the third embodiment. The reprogramming control system 2 according to the third embodiment is different from the first embodiment in that the reprogramming control device is provided on the vehicle 10 side instead of the center 50 side. According to the third embodiment, repro can be performed even in a place where wireless communication is not possible (for example, an underground parking lot).

  The reprogramming control device 300 includes a position detection unit 111, a repro availability determination unit 320, a signal output unit 330, a user confirmation unit 112, a learning unit 151, and a collection unit 131. In the third embodiment, the user parking position information DB 60 shown in FIG. 1 may be on the center 50 side or on the vehicle 10 side. Similarly, in the third embodiment, the OTA repro possibility determination DB 70 shown in FIG. 1 may be on the center 50 side or on the vehicle 10 side. When it exists in the center 50 side, the repro permission determination part 320 acquires the information memorize | stored in those each DB via the communication apparatus 120. FIG.

  In the third embodiment, the position detection unit 111 is an example of a position information acquisition unit that acquires position information of the vehicle 10. The repro availability determination unit 320 is an example of an availability determination unit that determines whether it is possible to perform reprogramming of the device mounted on the vehicle 10 at the vehicle position indicated by the position information acquired by the position detection unit 111. The signal output unit 330 is an example of a signal output unit that outputs a signal indicating that the reprogramming cannot be performed when the reprogramming determination unit 320 determines that the reprogramming is impossible. is there. The user confirmation unit 112 and the learning unit 151 are an example of a parking time acquisition unit that acquires a predicted parking time that is a predicted value of the time at which the vehicle 10 is parked at the vehicle position indicated by the position information acquired by the position detection unit 111. . The collection unit 131 is an example of a required time acquisition unit that acquires the required time for reprogramming of the repro target device 190. The collection unit 131 acquires the required time from the repro data management server installed in a facility such as the center 50 via the communication device 120.

  The reprogramming control device has been described above by way of the embodiment. However, the present invention is not limited to the above embodiment.
