Driving assistance device, driving assistance method, and computer readable medium

摘要

A driving assistance device includes: a switch information acquisition section that acquires switch information indicating a switch from a first travelling operation state to a second travelling operation state, in which the occupant drives manually; a degree of tension information acquisition section that acquires information indicating a degree of tension of an occupant; a perception state presentation section that presents a perception state indicating a state of stimulus perceived by the occupant using touch; and a controller that, when the switch information has been acquired, causes a first perception state corresponding to the degree of tension to be presented by the perception state presentation section as the perception state, and causes presentation by the perception state presentation section so as to transition from the first perception state to a second perception state determined for when the occupant manually drives.

1. A driving assistance device, comprising:
a switch information acquisition section that acquires switch information indicating a switch from a first travelling operation state, in which a driving assistance section performs driving assistance processing that assists driving of a vehicle by an occupant of the vehicle, to a second travelling operation state, in which the occupant drives the vehicle manually; a degree of tension information acquisition section that acquires information indicating a degree of tension of the occupant; a perception state presentation section that causes a part of the vehicle to present a tactile stimulus to the occupant; and a controller that, in cases in which the switch information has been acquired, causes a first level of the tactile stimulus, corresponding to the degree of tension, to be presented by the perception state presentation section, and subsequently causes the perception state presentation section to transition from presenting the first level of the tactile stimulus to a second level of the tactile stimulus that is determined for when the occupant manually drives the vehicle, the second level being different from the first level.
