Abstract

An automated driving unit implements an automated driving of a vehicle by implementing a present operation and a subsequent operation in order. The subsequent operation is an operation to be implemented subsequently to the present operation during the automated driving. A determining unit determines the subsequent operation of the vehicle. An imaging unit creates an image relevant to the subsequent operation according to information on the subsequent operation. A display unit indicates the image relevant to the subsequent operation while the automated driving unit implements the present operation.

First claim

What is claimed is:

a determining unit configured to determine the present operation and the subsequent operation;
an imaging unit configured to:
create an image relevant to the subsequent operation according to information on the subsequent operation;
create the image according to the acceleration quantity;
create the image representing an arrow in response to the acceleration quantity greater than or equal to an acceleration threshold; and
sharpen the arrow according to increase in the acceleration quantity; and

a display unit configured to indicate the image relevant to the subsequent operation while the automated driving unit implements the present operation.

2. The automated driving device according to claim 1 , wherein:
the subsequent operation further includes a steering quantity of a steering device of the vehicle; and
the imaging unit is configured to create the image according to the steering quantity.

3. The automated driving device according to claim 1 , wherein the imaging unit is configured to create the image representing
a rectangle in response to the acceleration quantity less than the acceleration threshold.

4. The automated driving device according to claim 1 , wherein the imaging unit is configured to:
increase a length of the image according to increase in the acceleration quantity; and
decrease the length of the image according to decrease in the acceleration quantity.

5. The automated driving device according to claim 1 , wherein:
the image includes a plurality of image elements; and
the imaging unit is configured to:
decrease a space between the image elements according to increase in the acceleration quantity; and

6. The automated driving device according to claim 1 , wherein the imaging unit is configured to:
increase a scroll speed of the image according to increase in the acceleration quantity; and
decrease the scroll speed of the image according to decrease in the acceleration quantity.

7. The automated driving device according to claim 2 , wherein the imaging unit is configured to create the image curved at a curvature according to the steering quantity.

8. The automated driving device according to claim 1 , wherein the display unit is at least one of:
a head-up display device configured to project the image; and
an indicator device located in an instrument cluster.

9. An automated driving device for a vehicle, comprising:
an automated driving unit configured to implement an automated driving by implementing a first operation and a second operation in order, wherein the second operation includes an acceleration quantity of an acceleration device of the vehicle;
a determining unit configured to determine a series of operations including the first operation and the second operation;
an imaging unit configured to:
create an image relevant to the second operation according to information on the second operation;
create the image according to the acceleration quantity;
create the image representing an arrow in response to the acceleration quantity greater than or equal to an acceleration threshold; and
sharpen the arrow according to increase in the acceleration quantity; and

a display unit configured to indicate the image while the automated driving unit implements the first operation.

10. The automated driving device according to claim 9 , further comprising:
a segmenting unit configured to divide a travelling path into a first segment and a second segment through which the vehicle is to travel in this order in the automated driving, and
the display unit is configured to indicate the image relevant to the second operation, which is to be implemented in the second segment, while the automated driving unit implements the first operation in the first segment in the automated driving.

11. The automated driving device according to claim 9 , further comprising:
a surrounding information acquisition unit configured to acquire surrounding information of the vehicle, wherein
the determining unit is configured to correct the first operation and the second operation according to the surrounding information, and
the imaging unit is configured to create the image according to information on the second operation as corrected.

12. An assisting device connected to an automated driving device, the automated driving device configured to implement a series of operations of a vehicle including a first operation and a second operation implemented in order, the assisting device comprising:
a communication unit configured to communicate with the automated driving device to retrieve information on the first operation and the second operation; and
an imaging unit configured to:
create images representing the first operation and the second operation, respectively, according to the information;
