## Abstract

An information presentation control device controlling information presentation to a driver in a vehicle equipped with autonomous driving function is provided. The information presentation control device is configured to: obtain a margin of the driver until an execution of driving change in which the driver takes over the at least partial driving task being performed by the autonomous driving; control a playback mode of a content presented by the information presentation device; stop the content, which is in a playback state, at a stop position in response to the execution of driving change; and set, according to the margin of the driver, a restart position of the content to which the content is rewound from the stop position to restart a playback of the content.

## Claims

### Claim 1

An information presentation control device, which controls an information presentation device presenting information to a driver in a vehicle, the vehicle being configured to perform a driving task by a vehicle control unit, during an autonomous driving executed by the vehicle, the information presentation control device comprising:
a margin obtaining unit obtaining a margin of the driver until an execution of driving change in which the driver takes over the driving task being performed by the vehicle control unit; and
a playback mode control unit controlling a playback mode of a content presented by the information presentation device,
wherein the playback mode control unit:
stops the content, which is in a playback state, at a stop position in response to the execution of driving change;
sets, according to the margin of the driver, a restart position of the content to which the content is rewound from the stop position to restart a playback of the content; and
sets the restart position of the content at an earlier playback point with a decrease of the margin of the driver.

### Claim 2 (depends on 1)

The information presentation control device according to claim 1, wherein
the playback mode control unit increases a rewind amount of the content from the stop position to the restart position with a decrease of the margin of the driver.

### Claim 3 (depends on 1)

The information presentation control device according to claim 1, wherein
the margin obtaining unit further obtains a driving load of the driver after the execution of driving change, and
the playback mode control unit determines, according to the driving load of the driver, whether to rewind the content from the stop position to the restart position in response to the driving change.

### Claim 4 (depends on 1)

The information presentation control device according to claim 1, wherein
the playback mode control unit sets the stop position of the content according to the margin of the driver.

### Claim 5 (depends on 4)

The information presentation control device according to claim 4, wherein
the playback mode control unit sets the stop position of the content at a later playback point with an increase of the margin of the driver.

### Claim 6

An information presentation control device, which controls an information presentation device presenting information to a driver in a vehicle, the vehicle being configured to perform a driving task by a vehicle control unit, during an autonomous driving executed by the vehicle, the information presentation control device comprising:
a margin obtaining unit obtaining a margin of the driver until an execution of driving change in which the driver takes over the driving task being performed by the vehicle control unit; and
a playback mode control unit controlling a playback mode of a content presented by the information presentation device,
wherein the playback mode control unit:
sets a stop position of the content according to the margin of the driver;
stops the content, which is in a playback state, at the stop position in response to the execution of driving change; and
sets the stop position of the content at a later playback point with an increase of the margin of the driver.

### Claim 7 (depends on 6)

The information presentation control device according to claim 6, wherein
the information presentation device includes a display device that displays an image on a screen of the display device,
the playback mode includes a display of the content on the display device,
the margin obtaining unit further obtains information indicating a movement of a line of sight of the driver, and
the playback mode control unit sets a restart position of the content to which the content is rewound from the stop position to restart a playback of the content according to a time when the line of sight of the driver deviates from the content displayed on the display device.

### Claim 8

An information presentation control device comprising:
a processor; and
a memory,
wherein
the information presentation control device controls an information presentation device presenting information to a driver in a vehicle,
the vehicle is configured to perform a driving task by autonomous driving, during an autonomous driving executed by the vehicle, and
the processor is configured to:
obtain a margin of the driver until an execution of driving change in which the driver takes over the driving task being performed by the autonomous driving;
control a playback mode of a content presented by the information presentation device;
stop the content, which is in a playback state, at a stop position in response to the execution of driving change;
set, according to the margin of the driver, a restart position of the content to which the content is rewound from the stop position to restart a playback of the content; and
set the restart position of the content at an earlier playback point with a decrease of the margin of the driver.

### Claim 9 (depends on 1)

The information presentation control device according to claim 1, wherein
the margin of the driver is a remaining period to an end time point of a driving change section or a remaining distance to an end position of the driving change section.

### Claim 10 (depends on 6)

The information presentation control device according to claim 6, wherein
the margin of the driver is a remaining period to an end time point of a driving change section or a remaining distance to an end position of the driving change section.

### Claim 11 (depends on 8)

The information presentation control device according to claim 8, wherein
the margin of the driver is a remaining period to an end time point of a driving change section or a remaining distance to an end position of the driving change section.
