PROBLEM TO BE SOLVED: To provide a technology for generating a travel route suitable for automatic travel regardless of a situation.SOLUTION: Information acquisition parts (31, 32) acquire information for travel control necessary for travel control of the automatic travel of a vehicle. A deterioration information storage part (23) recognizes a case where the accuracy of the information acquisition parts is less than a preliminarily set request level as accuracy deterioration, and stores the information of an accuracy deterioration road as a road where accuracy deterioration occurs. An information update part (22) acquires observation information related to the information acquisition part, and updates the storage content of the deterioration information storage part by using the observation information. Route generation parts (24, 40) generates a travel route excluding the accuracy deterioration road stored in the deterioration information storage part. A travel control part (36) executes automatic travel control in accordance with the travel route generated by the route generation part and information for travel control acquired by the information acquisition part.SELECTED DRAWING: Figure 1

    【課題】状況によらず自動走行に適した走行経路を生成する技術を提供する。【解決手段】情報取得部(31,32)は、車両の自動走行の走行制御に必要な走行制御用情報を取得する。劣化情報記憶部(23)は、情報取得部の精度が予め設定された要求レベル未満となる場合を精度劣化とし、精度劣化が生じる道路である精度劣化道路の情報を記憶する。情報更新部(22)は、情報取得部に関わる観測情報を取得し、該観測情報を用いて劣化情報記憶部の記憶内容を更新する。経路生成部(24、40)は、劣化情報記憶部に記憶されている精度劣化道路を除外した走行経路を生成する。走行制御部(36)は、経路生成部により生成された走行経路および情報取得部にて取得された走行制御用情報に従って自動走行制御を実施する。【選択図】図1
