Driving assistance apparatus, driving assistance method, and computer-readable storage medium storing driving assistance program
A driving assistance apparatus executes a moving control to autonomously control a vehicle. The apparatus informs a driver of contents of a voice operation process planned to be executed for the moving control in accordance with utterance contents of the driver acquired by voice recognition, and execute the voice operation process when an approval operation to approve the informed contents, is performed by the driver. The apparatus cancels a plan to execute the voice operation process and informs the driver that executing the voice operation process is not permitted when a moving situation of the vehicle becomes a predetermined situation which does not permit executing the voice operation process after informing the driver of the contents of the voice operation process planned to be executed for the moving control and before the approval operation is performed.
1. A driving assistance apparatus, comprising an electronic control unit configured to execute a moving control to autonomously control a vehicle,
the electronic control unit being configured to:
(i) inform a driver of the vehicle of contents of a voice operation process planned to be executed for the moving control in accordance with utterance contents of the driver acquired by voice recognition; and
(ii) execute the voice operation process when an approval operation to approve the informed contents, is performed by the driver,
wherein the electronic control unit is configured to:
(i) cancel a plan to execute the voice operation process and inform the driver that executing the voice operation process is not permitted when a moving situation of the vehicle becomes a predetermined situation which does not permit executing the voice operation process after the electronic control unit informs the driver of the contents of the voice operation process planned to be executed for the moving control and before the approval operation is performed; or
(ii) cancel the plan to execute the voice operation process and inform the driver that executing the voice operation process is not permitted when the moving situation of the vehicle is predicted to become the predetermined situation after the electronic control unit informs the driver of the contents of the voice operation process planned to be executed for the moving control and before the approval operation is performed; or
(iii) cancel the plan to execute the voice operation process and inform the driver that executing the voice operation process is not permitted when the moving situation of the vehicle becomes the predetermined situation when and after the electronic control unit acquires the utterance contents of the driver by the voice recognition and before the electronic control unit completes informing the driver of the contents of the voice operation process planned to be executed for the moving control; or
(iv) cancel the plan to execute the voice operation process and inform the driver that executing the voice operation process is not permitted when the moving situation of the vehicle is predicted to become the predetermined situation when and after the electronic control unit acquires the utterance contents of the driver by the voice recognition and before the electronic control unit completes informing the driver of the contents of the voice operation process planned to be executed for the moving control.
2. A driving assistance method of executing a moving control to autonomously control a vehicle, the driving assistance method comprising steps of:
(i) informing a driver of the vehicle of contents of a voice operation process planned to be executed for the moving control in accordance with utterance contents of the driver acquired by voice recognition; and
(ii) executing the voice operation process when an approval operation to approve the informed contents, is performed by the driver,
wherein the driving assistance method comprises steps of:
(i) cancelling a plan to execute the voice operation process and informing the driver that executing the voice operation process is not permitted when a moving situation of the vehicle becomes a predetermined situation which does not permit executing the voice operation process after informing the driver of the contents of the voice operation process planned to be executed for the moving control and before the approval operation is performed; or
(ii) cancelling the plan to execute the voice operation process and informing the driver that executing the voice operation process is not permitted when the moving situation of the vehicle is predicted to become the predetermined situation after informing the driver of the contents of the voice operation process planned to be executed for the moving control and before the approval operation is performed; or
(iii) cancelling the plan to execute the voice operation process and informing the driver that executing the voice operation process is not permitted when the moving situation of the vehicle becomes the predetermined situation when and after acquiring the utterance contents of the driver by the voice recognition and before completing informing the driver of the contents of the voice operation process planned to be executed for the moving control; or
(iv) cancelling the plan to execute the voice operation process and informing the driver that executing the voice operation process is not permitted when the moving situation of the vehicle is predicted to become the predetermined situation when and after acquiring the utterance contents of the driver by the voice recognition and before completing informing the driver of the contents of the voice operation process planned to be executed for the moving control.
3. A non-transitory computer-readable storage medium storing a driving assistance program configured to execute a moving control to autonomously control a vehicle,
the driving assistance program being configured to:
(i) inform a driver of the vehicle of contents of a voice operation process planned to be executed for the moving control in accordance with utterance contents of the driver acquired by voice recognition; and
(ii) execute the voice operation process when an approval operation to approve the informed contents, is performed by the driver,
wherein the driving assistance program is configured to:
(i) cancel a plan to execute the voice operation process and inform the driver that executing the voice operation process is not permitted when a moving situation of the vehicle becomes a predetermined situation which does not permit executing the voice operation process after informing the driver of the contents of the voice operation process planned to be executed for the moving control and before the approval operation is performed; or
(ii) cancel the plan to execute the voice operation process and inform the driver that executing the voice operation process is not permitted when the moving situation of the vehicle is predicted to become the predetermined situation after informing the driver of the contents of the voice operation process planned to be executed for the moving control and before the approval operation is performed; or
(iii) cancel the plan to execute the voice operation process and inform the driver that executing the voice operation process is not permitted when the moving situation of the vehicle becomes the predetermined situation when and after acquiring the utterance contents of the driver by the voice recognition and before completing informing the driver of the contents of the voice operation process planned to be executed for the moving control; or
(iv) cancel the plan to execute the voice operation process and inform the driver that executing the voice operation process is not permitted when the moving situation of the vehicle is predicted to become the predetermined situation when and after acquiring the utterance contents of the driver by the voice recognition and before completing informing the driver of the contents of the voice operation process planned to be executed for the moving control.
