- the update necessity determination unit 210 determines whether or not the external environment recognition device 100 is updated based on the feature data acquired from the infrastructure 300 and stored in the feature data storage unit 230 and the update data stored in the control center side update data storage unit 240.

- the horizontal axis is the true value and the vertical axis is the external recognition data, if the error is small, it is mapped to an area where a software update is not required, and if the error is large, it is mapped to an area where a software update is required, and it is possible to determine whether or not a software update is required.
- the threshold value for the area where a software update is required and the area where it is not required may be determined according to the specifications of the external recognition device 10, or may be set statistically. Generally, the further away an object is, the lower the recognition accuracy becomes, so the threshold value may be set to be relaxed.

- the thresholds shown in FIG. 5 are displayed on a perfect circle, but they may also be displayed as ellipses depending on the characteristics of the external recognition device 10.
- the determination of whether or not the recognition software needs to be updated is made when the amount of error in the external recognition data exceeds a threshold value when multiple vehicles 1 are in the same location. This is because it is determined that the scene in that location is difficult for the recognition software to recognize, and that the software needs to be improved. On the other hand, if only a specific vehicle exceeds the threshold value, it can be determined that there is a problem specific to the vehicle (such as a deviation due to aging) rather than the recognition software.
- the raw data acquisition location determination unit 212 determines that the recognition software needs to be updated, it requests the vehicle 1 to acquire the raw data required to update the recognition software. Specifically, it extracts locations where the amount of error in the external environment recognition data exceeds a threshold in multiple vehicles 1, and transmits these to the vehicle-side receiving unit 32 of the vehicle 1 via the notification unit 270.
- the raw data acquisition location is set based on the acquired vehicle direction data and road shape in a range away from the location where a feature with low recognition accuracy is installed, or in cases where the orientation in which the feature can be recognized is limited due to the traveling direction of the vehicle 1, such as a sign or traffic light.
- the raw data acquisition location is transmitted to the vehicle 1 equipped with the recognition software determined to need to be updated.
- the recognition software needs to be updated based on the external recognition data of multiple vehicles 1, it is possible to accurately identify locations that are difficult for the recognition software to recognize, and obtain raw data to deal with scenes that are difficult to recognize. Furthermore, because the processing is based on the external recognition data of multiple vehicles 1, it is possible to determine whether the problem is with the recognition software or a problem specific to a particular vehicle.
- the update software generation unit 220 analyzes, improves, and verifies the recognition software when the update necessity determination unit 210 determines that an update of the recognition software is necessary, and distributes the updated software to the vehicle 1, and is equipped with a recognition software analysis unit 221, a recognition software improvement unit 222, and a recognition software verification unit 223.
- the recognition software database 250 stores the version history and change history of the recognition software, and transmits recognition software information to the recognition software update unit when the recognition software is analyzed, improved, and verified.
- the update software generation unit 220 may request the required raw data from the vehicle 1 depending on the process status of the analysis, improvement, and update of the recognition software.
- the recognition software analysis unit 221 performs an analysis of the recognition software based on the update data that can be obtained from the control center side update data storage unit 240.
- the raw data of the update data includes image data, video data, point cloud data, etc. used to generate external recognition data.
- the version of the recognition software to be updated is obtained from the recognition software database 250, the raw data is input to the recognition software, and it is analyzed whether recognition is performed reliably. For example, by using update data that the update necessity determination unit 210 has determined to require a software update, it is possible to focus the analysis on scenes where the recognition software had low recognition accuracy.
- the analysis results are sent to the recognition software improvement unit 222, and include causes of low recognition accuracy such as the feature being recognized but the relative distance not being calculated correctly, the feature not being recognized, the feature having an unusual shape, or an obstruction between the feature and the vehicle 1.
- the recognition software improvement unit 222 improves the recognition software based on the analysis results obtained from the recognition software analysis unit 221. Specifically, additional learning of the recognition software is performed using update data, and parameters for calculating the relative distance between the vehicle 1 and features are updated. The improved software is sent to the recognition software verification unit 223.
- the recognition software verification unit 223 verifies the recognition software improved by the recognition software improvement unit 222. Specifically, it verifies whether improvements have been made in scenes where the improved recognition software is problematic. It also refers to the update history of the recognition software stored in the recognition software database 250 to check whether there are any problems with the changes made to the previous recognition software. If it is determined as a result of the verification that there are no problems with the improved recognition software, it stores it in the recognition software database 250 as the latest version and distributes the recognition software to the vehicle 1 via the notification unit 270.
- steps S1 and S2 external recognition data relating to features such as road structures present around the vehicle 1, and vehicle position data and vehicle direction data at the time of acquiring the external recognition data are acquired by the external recognition device 10 and vehicle information acquisition device 20 of the vehicle 1, and are stored in the vehicle-side update data storage unit 33.

- step S3 the control center 200 stores the update data transmitted from the vehicle 1 in the control center update data storage unit 240 via the control center receiving unit 260.
- the update necessity determination unit 210 uses the update data stored in the control center update data storage unit 240 and the feature data stored in the feature data storage unit 230 to calculate the accuracy of the external environment recognition data included in the update data in the recognition accuracy calculation unit 211.
- step S4 it is determined whether or not the recognition software needs to be updated based on the accuracy of the external recognition data calculated in step S3. If it is determined that an update is necessary, the process proceeds to step S5. If it is determined that an update is not necessary, the process ends, and it is determined whether or not the recognition software needs to be updated for the next external recognition data.
- the raw data acquisition location determination unit 212 determines the raw data acquisition location required for updating the recognition software. Basically, the raw data acquisition location is the location where the external recognition data determined to need updating was acquired. The raw data acquisition location is notified to the vehicle 1 via the notification unit 270. The raw data acquisition location is also notified to multiple vehicles other than the vehicle that acquired the external recognition data.
- the software update device 30 stores the raw data acquisition location notified by the control center 200 in the vehicle-side update data storage unit 33 via the vehicle-side receiver 32.
- the external environment recognition device 10 normally transmits external environment recognition data to the software update device 30, but if the raw data acquisition location has been notified, when the vehicle 1 passes the raw data acquisition location, it also transmits the raw data used to generate the external environment recognition data to the software update device 30.
- the vehicle information acquisition device 20 also transmits vehicle position data and vehicle direction data to the software update device 30.
- the software update device 30 stores update data including the external environment recognition data, raw data, vehicle position data, and vehicle direction data acquired from the external environment recognition device 10 and the vehicle information acquisition device 20 in the vehicle-side update data storage unit 33.
- the software update device 30 transmits the update data to the control center 200 via the vehicle-side transmitter 31.
- step S8 the control center 200 stores the update data acquired via the control center receiving unit 260 in the control center update data storage unit 240.
- the recognition software analysis unit 221 uses the update data stored in the control center update data storage unit 240 to analyze the recognition software of the external environment recognition device 10. The analysis result is output to the recognition software improvement unit 222.
- step S9 the recognition software improvement unit 222 improves the recognition software of the external environment recognition device 10 based on the analysis results by the recognition software analysis unit 221.
- the improved recognition software is output to the recognition software verification unit 223.
- step S10 the recognition software verification unit 223 verifies the recognition software of the external environment recognition device 10 that has been improved by the recognition software improvement unit 222. If the verification results in a determination that there is no problem with the improved recognition software, it stores it in the recognition software database 250.
- step S11 the control center 200 distributes the latest recognition software stored in the recognition software database 250 to the vehicle 1 via the notification unit 270.
- the recognition accuracy calculation unit 211 compares the true value with the external recognition data, and when it is determined that the recognition software needs to be updated, the raw data acquisition location determination unit 212 sets the raw data acquisition location.
- a raw data acquisition request may be made to a vehicle 1 traveling in time periods such as early morning or twilight, or in order to improve the degradation of the recognition accuracy of the recognition software due to bad weather, a raw data acquisition request may be made to a vehicle 1 traveling in rainy or snowy weather.
- feature data is used to determine whether or not the recognition software needs to be updated, but the feature data stored in the feature data storage unit 230 does not necessarily determine the actual situation.
- the information stored in the feature data may differ from the actual road shape or the location of road structures due to road construction or natural disasters. Even in such a situation, it can be determined that the feature data is different based on the update data acquired by the vehicle 1. If it is determined that the feature data is different, the feature data may be updated, or processing may be performed such as not acquiring external environment recognition data related to features at that location.

- the software update device 30 includes a vehicle side update data storage unit 33 that stores the update data acquired at the acquisition location notified by the notification unit 270, and the vehicle side transmission unit 31 transmits the update data acquired at the acquisition location stored in the vehicle side update data storage unit 33 to the control center 200. This makes it possible to generate update software for the external recognition device 10 by investigating the cause of the decrease in recognition accuracy using raw data from a location where the software of the external recognition device 10 has difficulty recognizing.
- the notification unit 270 notifies the software update device 30 mounted on a vehicle other than the vehicle 1 that acquired the external environment recognition data of the acquisition location.

Abstract
Description
ソフトウェア更新装置30は、外界認識装置10と車両情報取得装置20から取得した外界認識データとローデータと自車位置データと自車方角データを含む更新用データを管制センタ200に送信し、管制センタ200より配信される外界認識装置10の認識ソフトウェア(更新ソフトウェア)を受信し、外界認識装置10のソフトウェア更新を実施する装置であり、車両側送信部31と、車両側受信部32と、車両側更新用データ記憶部33を有する。なお、ソフトウェア更新装置30は、具体的には、CPUやメモリ(ROM、RAM)を備えたECU(Electronic Control Unit)に搭載されたマイコンであり、メモリ内に格納された各種プログラムをCPUが実行することで、各機能を実現する装置である。
更新要否判定部210は、地物データ記憶部230に格納されたインフラ300より取得した地物データと、管制センタ側更新用データ記憶部240に格納された更新用データに基づき、外界認識装置10の認識ソフトウェアの更新要否を判定する。以下、外界認識データが車両1から地物までの相対位置である場合の判定方法を具体的に説明する。認識精度算出部211は、更新用データに含まれる車両位置データ及び車両方角データと地物データとに基づき、車両1から地物までの相対位置の真値を算出し、当該真値と更新用データに含まれる外界認識データとの差分(誤差量)を算出する。そして、誤差量があらかじめ設定した閾値を超えたか否かを判断する。例えば、図3から図5に例示するように、真値と外界認識データをグラフにマッピングして判定しても良い。ここで、閾値の設定は、外界認識装置10の仕様により定めても良いし、統計的に設定しても良い。以上、外界認識データと真値との比較結果に基づいて認識ソフトウェアの更新要否を判定する方法を説明したが、更新要否の判定方法はこれに限らず、外界認識データを基に算出される別のパラメータと、車両位置データと車両方角データと地物データとを基に算出される当該パラメータの真値との比較結果に基づいて判定しても良い。
更新ソフト生成部220は、更新要否判定部210において認識ソフトウェアの更新が必要と判定された場合に、認識ソフトウェアの解析、改善、検証を実施し、更新されたソフトウェアを車両1に配信し、認識ソフト解析部221、認識ソフト改善部222、認識ソフト検証部223を備える。認識ソフトデータベース250は、認識ソフトウェアのバージョン履歴や変更履歴が保管されており、認識ソフトウェアを解析・改善・検証を実施する際に、認識ソフト更新部に認識ソフトウェア情報を送信する。更新ソフト生成部220は、認識ソフトウェアの解析、改善、更新のプロセス状況に応じて必要なローデータを車両1に要求しても良い。
前述した実施形態では、認識精度算出部211において真値と外界認識データを比較し、認識ソフトウェアの更新が必要と判定した場合、ローデータ取得場所決定部212において、ローデータ取得場所を設定していたが、例えば、太陽の日差しによる認識ソフトウェアの認識精度低下を改善するために朝方や薄暮といった時間帯を走行する車両1に対してローデータ取得要求をしても良いし、悪天候による認識ソフトウェアの認識精度低下を改善するために雨や雪が降る天候の中走行する車両1に対してローデータ取得要求をしても良い。
本実施形態では、車両1に搭載された外界認識装置10のソフトウェアを更新するソフトウェア更新装置30と、ソフトウェア更新装置30とネットワークを介して通信を行い外界認識装置10のソフトウェア更新に用いる更新ソフトウェアを配信する管制センタ200とを含むソフトウェア更新システムにおいて、ソフトウェア更新装置30は、外界認識装置10により生成された外界認識データを管制センタ200に送信する車両側送信部31を備え、管制センタ200は、前記外界認識データに基づいて前記ソフトウェアの更新要否を判定する更新要否判定部210を備える。
