Definitions
- the present disclosure relates to a notification device and a notification method for notifying a moving driver of an operation requesting implementation.
- driving authority may be transferred to the driver from the vehicle being autonomously driven. For example, when the vehicle finishes driving in the autonomous driving lane, the driving authority of the vehicle is transferred from the vehicle to the driver. However, if the automatic driving of the vehicle continues for a long time, the reaction speed of the driver may become slow and the driver may not be able to get a sense of driving operation.
- Patent Document 1 there is a vehicle control device described in Patent Document 1 as a conventional technique for regaining a driver's sense of driving operation that has become dull due to automatic driving of a vehicle.
- This vehicle control device is mounted on a vehicle in which, during automatic driving, the driving operation unit used for the driving operation and the driving device for moving the vehicle are temporarily separated from each other. Therefore, the driving operation using the driving operation unit by the driver is a so-called dummy driving operation that is not reflected in the movement of the vehicle even if it is performed.
- the vehicle control device described in Patent Document 1 is a so-called manual driving preparation period from the notification that the driving authority is transferred from the vehicle to the driver to the transfer of the driving authority to the driver.
- the operation request is presented to the driver, the input of the signal based on the driver's operation is accepted, and the difference between the value obtained from the signal based on the driver's operation and the reference value according to the operation request is Switch the vehicle to manual driving if it is within acceptable limits.
- the driver may transfer the driving authority from the vehicle to himself even when the vehicle is automatically driving, so the driver does not always perform only the operation unrelated to the driving operation of the vehicle, and the driver does not always perform a dummy driving. Often the operation is carried out.
- the vehicle since the vehicle has various driving operations, in order for the driver to regain the driving operation feeling, different driving operations are performed evenly, rather than performing the same driving operation multiple times during the preparation period for manual driving. It is better to carry out.
- the driving operation is performed for the driver regardless of whether or not the driving operation has already been performed by the driver before the preparation period for manual driving. Is required. Therefore, the vehicle control device may re-request the driver to perform the driving operation that had been completed before the preparatory period for manual driving. In this case, the driver needs to perform the same driving operation that has been completed again during the preparation period for manual driving, and there is a problem that other driving operations cannot be performed during that period.
- the present disclosure solves the above problems, and is a notification device and a notification that can prevent the driver from being requested to perform the operation completed before the transfer of the driving authority to the driver is notified.
- the purpose is to get a method.
- the notification device has an information acquisition unit that acquires operation information indicating the operation status of the driver of the mobile body, and the driver has the driving authority after notifying the transfer of the driving authority from the mobile body to the driver. It is equipped with a notification unit that notifies the driver of the operation requested to be performed before the transfer, and the notification unit is provided by the driver among the operations requesting the driver to perform the operation based on the operation information. Notify the operation that has not been completed.
- the notification device According to the notification device according to the present disclosure, among the operations for requesting the driver to perform the operation from the notification of the transfer of the driving authority to the driver to the transfer of the driving authority to the driver, the driver Is notified of operations that have not been completed. Thereby, the notification device according to the present disclosure can prevent the driver from being requested to perform the operation that has been completed before the transfer of the driving authority to the driver is notified.

図10は、実施の形態2に係る通知方法を示すフローチャートであり、通知装置10Aの動作を示している。図10の一連の処理は、例えば、自動運転中の車両において、車両制御装置2が、車両から運転者への運転権限の移譲を決定し、車両から運転者へ運転権限が移譲される予定であることを示す予定情報を通知装置10Aに出力した時点で開始される。ただし、車両制御装置2は、予定情報の出力とは無関係に、センサ群3によって逐次検出されたセンサ情報に基づいて、運転者の操作状況を示す操作情報を生成し、生成した操作情報の時系列データを保持している。
図12は、実施の形態3に係る通知装置10Bの構成を示すブロック図である。通知装置10Bは、運転者が実施を完了していない操作の数に応じて、車両から運転者へ運転権限が移譲されることおよび運転者に実施を要求する操作の通知時期を変更する。通知装置10Bは、図12に示すように、情報取得部101および通知部102Bを備える。通知部102Bは、判定部1021および通知制御部1022Bを備えている。図12において、図1と同一の構成要素には同一の符号を付して説明を省略する。
図13は、実施の形態3に係る通知方法を示すフローチャートであり、通知装置10Bの動作を示している。図13の一連の処理は、例えば、自動運転中の車両において、車両制御装置2が、車両から運転者への運転権限の移譲を決定し、車両から運転者へ運転権限が移譲される予定であることを示す予定情報を通知装置10Bに出力した時点で開始される。ただし、車両制御装置2は、予定情報の出力とは無関係に、センサ群3によって逐次検出されたセンサ情報に基づいて、運転者の操作状況を示す操作情報を生成し、生成した操作情報の時系列データを保持している。
図15は、実施の形態4に係る通知装置10Cの構成を示すブロック図である。通知装置10Cは、運転者が実施を完了していない操作の内容に応じて、車両から運転者へ運転権限が移譲されることおよび運転者に実施を要求する操作の通知時期を変更する。通知装置10Cは、図15に示すように、情報取得部101および通知部102Cを備える。通知部102Cは、判定部1021および通知制御部1022Cを備えている。図15において、図1と同一の構成要素には同一の符号を付して説明を省略する。
図16は、実施の形態4に係る通知方法を示すフローチャートであり、通知装置10Cの動作を示している。図16の一連の処理は、例えば、自動運転中の車両において、車両制御装置2が、車両から運転者への運転権限の移譲を決定し、車両から運転者へ運転権限が移譲される予定であることを示す予定情報を通知装置10Cに出力した時点で開始される。ただし、車両制御装置2は、予定情報の出力とは無関係に、センサ群3によって逐次検出されたセンサ情報に基づいて、運転者の操作状況を示す操作情報を生成し、生成した操作情報の時系列データを保持している。
