Vehicle driving switching device, vehicle driving system, and vehicle driving switching method

A vehicle driving system that switches between (i) automatic driving by an automatic driving device which a vehicle is equipped with and (ii) manual driving by a driver of the vehicle, the vehicle driving system comprising:

• a driving rule determination acquisition unit configured to acquire driving rule determination information under an assumed manual driving, the driving rule determination information under the assumed manual driving being information that indicates a determination result of comparison between (i) a driving rule and (ii) an assumed manual driving characteristic being a characteristic of a host vehicle being the vehicle equipped with the automatic driving device when it is assumed that the host vehicle travels by the manual driving on a travel path generated by the automatic driving device;
• a driving switching unit configured to perform a driving mode switching of switching a driving mode between an automatic driving mode in which the automatic driving is performed and a manual driving mode in which the manual driving is performed;
• and
• a switching determination unit configured to permit the driving mode switching by the driving switching unit from the automatic driving mode to the manual driving mode based on condition that the driving rule determination information under the assumed manual driving indicates that the assumed manual driving characteristic is assumed to comply with the driving rule;
• an evaluation information determination unit sequentially determining evaluation information for evaluating a manual driving under execution during the manual driving;
• and
• a display device displaying thereon the evaluation information determined by the evaluation information determination unit, wherein
• the switching determination unit is further configured to switch from the automatic driving mode to the manual driving mode by considering (i) an operation amount of the manual driving mode and an operation amount of the automatic driving mode and (ii) an evaluation value indicating separation of the operation amount of the manual driving from the operation amount of the automatic driving.

A computer-implemented vehicle driving switching method performed by a processor to switch between (i) automatic driving by an automatic driving device with which a vehicle is equipped and (ii) manual driving by a driver of the vehicle,

• the vehicle driving switching method comprising:
• acquiring driving rule determination information under the automatic driving, the driving rule determination information under the automatic driving being information that indicates a determination result of comparison between (i) a driving rule and (ii) an automatic driving characteristic being a characteristic of a host vehicle being the vehicle equipped with the automatic driving device when the host vehicle travels by the automatic driving on a travel path generated by the automatic driving device;
• and
• permitting a driving mode switching by a driving switching unit of switching a driving mode between an automatic driving mode in which the automatic driving is performed and a manual driving mode in which the manual driving is performed based on condition that the driving rule determination information under the automatic driving indicates that the automatic driving characteristic complies with the driving rule;
• sequentially determining evaluation information for evaluating a manual driving under execution during the manual driving;
• and
• displaying the evaluation information on a display device, wherein
• switching of the manual driving mode to the automatic driving mode is performed by considering (i) an operation amount of the manual driving mode and an operation amount of the automatic driving mode and (ii) an evaluation value indicating separation of the operation amount of the manual driving from the operation amount of the automatic driving.

• a switching determination unit configured to permit the driving mode switching to the automatic driving by the driving switching unit based on condition that the driving rule determination information under the automatic driving acquired by the driving rule determination acquisition unit indicates that the automatic driving characteristic complies with the driving rule;
• and
• a responsibility value calculation unit configured to sequentially calculate the responsibility value when the automatic driving device performs the automatic driving;
• an evaluation information determination unit sequentially determining evaluation information for evaluating a manual driving under execution during the manual driving;
• and
• a display device displaying thereon the evaluation information determined by the evaluation information determination unit, wherein
• the switching determination unit is further configured to switch from the manual driving mode to the automatic driving mode by considering (i) an operation amount of the manual driving mode and an operation amount of the automatic driving mode and (ii) an evaluation value indicating separation of the operation amount of the manual driving from the operation amount of the automatic driving.
