ARITHMETIC UNIT, ON-VEHICLE DEVICE, AND AUTOMATIC DRIVING SYSTEM

To provide information for enabling automatic driving at a point at which the automatic driving is interrupted in the past.SOLUTION: An arithmetic unit includes a server communication part for receiving information of an interruption position being a position at which automatic driving is interrupted from an on-vehicle device mounted on a first vehicle, and receiving manual driving information being information of manual driving in a second vehicle in an area of an interruption position from an on-vehicle device mounted on the second vehicle, an extraction part for extracting a control point being a point about change in a direction of travel from the manual driving information in the area of the interruption position, and a creation part for creating knowledge information for enabling the generation of a track for changing the direction of travel of the vehicle on the basis of the control point. Further, the server communication part transmits at least one of the knowledge information and information showing a track of the vehicle generated by using the knowledge information to an on-vehicle device mounted on a third vehicle, the third vehicle is the same as either the first vehicle or the second vehicle, or is different from both the first vehicle and the second vehicle, and the first vehicle is the same as the second vehicle, or is different from the second vehicle.SELECTED DRAWING: Figure 2 【課題】過去に自動運転が中断された地点で自動運転を可能とする情報を提供できる。【解決手段】演算装置は、第１車両に搭載される車載装置から自動運転が中断された位置である中断位置の情報を受信し、第２車両に搭載される車載装置から中断位置の領域における第２車両における手動運転の情報である手動運転情報を受信するサーバ通信部と、中断位置の領域における手動運転情報から進行方向の変更に関する地点である制御点を抽出する抽出部と、制御点に基づいて、車両の進行方向を変更する軌道の生成を可能とする知識情報を作成する作成部とを備え、サーバ通信部はさらに、知識情報、および知識情報を用いて生成した車両の軌跡を示す情報の少なくとも一方を第３車両の車載装置に送付し、第３車両は、第１車両および第２車両のいずれかと同一、または第１車両および第２車両のいずれとも異なり、第１車両は、第２車両と同一、または第２車両とは異なる。【選択図】図２
