Abstract

An information presenting device is mounted in an autonomous vehicle in which an action candidate for the vehicle to take is settable based on selection from presented selection information made by an occupant. The information presenting device sets the action candidate for the autonomous vehicle to take, calculates a selection margin time from a current time point to a time point at which the occupant should complete the selection from the selection information, sets the selection information based on the action candidate depending on the selection margin time, and presents the set selection information to the occupant.

First claim

1 . An information presenting device in an autonomous vehicle in which an action candidate for the vehicle to take is set based on selection by an occupant, the information presentation device configured to present selection information from which the selection is made by the occupant, comprising:
a selection margin time calculator configured to calculate a selection margin time based on an position where an execution of the action candidate selected from the selection information by the occupant is started; a selection information setter configured to set the selection information depending on the selection margin time; a presenter configured to present the selection information set by the selection information setter to the occupant; and an input unit configured to receive the selection from the selection information presented by the presenter, which is made by an operation of the occupant.

2 . The information presenting device according to claim 1 , comprising an action candidate setter configured to set the action candidate for the autonomous vehicle; wherein the selection information setter sets the selection information based on the action candidate, depending on the selection margin time.

3 . The information presenting device according to claim 2 , wherein the selection information setter sets the selection information by setting selection items and a maximum number of choices based on the action candidate, depending on the selection margin time.

4 . The information presenting device according to claim 3 , wherein the selection information setter sets the selection items such that the shorter the selection margin time is, the simpler the selection items are.

5 . The information presenting device according to claim 3 , wherein the selection information setter sets the maximum number of choices such that the shorter the selection margin time is, the smaller the maximum number of choices is.

6 . The information presenting device according to claim 3 , wherein the selection information setter sets the selection information based on the action candidate related to at least one of turning, lane change, cruising, branching, and merging.

7 . The information presenting device according to claim 3 , wherein
the selection information setter determines a most-recommended selection item out of the selection items, and when the occupant selects a selection item other than the most-recommended selection item, the presenter confirms a selection content with the occupant.

8 . The information presenting device according to claim 1 , wherein the presenter presents the selection margin time and the selection information to the occupant.

9 . The information presenting device according to claim 8 , wherein the presenter changes a presentation state of the selection margin time depending on the selection margin time.

10 . The information presenting device according to claim 2 , wherein the selection margin time calculator calculates the selection margin time based on a distance from a current position of the autonomous vehicle to an action execution point where the action candidate is executed.

11 . The information presenting device according to claim 2 , wherein the selection margin time calculator calculates the selection margin time based on a degree of margin in condition determined from the number of other vehicles in front of the autonomous vehicle and from a distance from a current position of the autonomous vehicle to an action execution point where the action candidate is executed.

12 . The information presenting device according to claim 1 , wherein the selection margin time calculator calculates the selection margin time based on a degree of disturbance to a periphery determined from the number of other vehicles behind the autonomous vehicle.

13 . The information presenting device according to claim 1 , wherein the selection margin time calculator calculates the selection margin time based on a degree of congestion in a periphery determined from the number of other vehicles around the autonomous vehicle.

14 . The information presenting device according to claim 1 , wherein the selection information setter sets the selection information depending on vehicles around the autonomous vehicle.

15 . The information presenting device according to claim 1 , wherein
the presenter keeps presenting the selection information during the selection margin time, and the input unit allows reselection from the selection information during the selection margin time.

16 . The information presenting device according to claim 1 , wherein the presenter presents the selection information to the occupant by using at least one of an image and a sound.

17 . An information presenting method of an information presenting device in an autonomous vehicle in which an action candidate for the vehicle to take is set based on selection by an occupant, the information presentation device configured to present selection information from which the selection is made by the occupant, the information presenting method comprising:
calculating a selection margin time based on an position where an execution of the action candidate selected from the selection information by the occupant is started; setting the selection information depending on the selection margin time; presenting the set selection information to the occupant; and receiving the selection from the presented selection information which is made by an operation of the occupant.
