Abstract

A vehicle display control device includes: a driving mode acquisition section that acquires information on which of a manual driving mode or an autonomous driving mode is a driving mode; an operation intervention detection section that, in a case in which the driving mode acquired by the driving mode acquisition section is the autonomous driving mode, detects a driving operation intervention by the vehicle occupant; and a display control section that displays vicinity information of the vehicle at a display unit provided at a vehicle cabin at least in a case in which the driving mode acquired by the driving mode acquisition section is the autonomous driving mode, wherein, in a case in which a driving operation intervention is detected by the operation intervention detection section, the display control section changes background information of the vicinity information and displays the background information at the display unit.

First claim

What is claimed is:

1. A vehicle display control device comprising a processor configured to:
acquire information regarding a vehicle indicating which of a manual driving mode or an autonomous driving mode is set as a driving mode in the vehicle, the vehicle traveling on a road via driving operations performed by a vehicle occupant in the manual driving mode, and the vehicle traveling on the road independently of driving operations by the vehicle occupant in the autonomous driving mode;
in a case in which the acquired driving mode is the autonomous driving mode, detect a driving operation intervention by the vehicle occupant;
in a case in which the driving operation intervention is detected, stop a driving assistance function related to an operating device by which the driving operation intervention was detected; and
in the case in which the driving operation intervention is detected, display a warning image related to the operating device on a display provided inside a vehicle cabin of the vehicle,
display speed marks at the display, a spacing of the speed marks changing in accordance with a speed of the vehicle,
in a case in which an accelerator operation for the vehicle is detected, hide display of the speed marks, and
when the speed of the vehicle is a first speed, the speed marks are displayed with a first spacing, and when the speed of the vehicle is a second speed, that is higher than the first speed, the speed marks are displayed with a second spacing that is larger than the first spacing.

2. The vehicle display control device according to claim 1 , wherein the processor is configured to detect, as the driving operation intervention, at least one of a steering operation by the vehicle occupant or the accelerator operation by the vehicle occupant.

3. The vehicle display control device according to claim 2 , wherein the processor is configured to display a planned running route of the vehicle at the display and, in a case in which the steering operation is detected, hide display of the planned running route.

4. The vehicle display control device according to claim 3 , wherein the processor is configured to display the planned running route superposed on an image of a driving lane of the vehicle.

5. The vehicle display control device according to claim 2 , wherein the processor is configured to:
display a preceding vehicle at the display, and
in a case in which the accelerator operation for the vehicle is detected, tone down a color of the preceding vehicle and display the preceding vehicle.

6. The vehicle display control device according to claim 2 , wherein the processor is configured to, in a case in which at least one of a manual steering operation intervention or a manual accelerator operation intervention is detected, display the warning image so as to represent the steering operation or the accelerator operation at the display.

7. The vehicle display control device according to claim 6 , wherein the processor is configured to display different warning images in a case in which the manual steering operation intervention is detected and in a case in which the manual accelerator operation intervention is detected.

8. A vehicle display system comprising:
the vehicle display control device according to claim 1 ,
wherein the processor is configured to display vicinity information of the vehicle on the display.

9. A vehicle display control method comprising a processor:
acquiring information regarding a vehicle indicating which of a manual driving mode or an autonomous driving mode is set as a driving mode in the vehicle, the vehicle traveling on a road via driving operations performed by a vehicle occupant in the manual driving mode, and the vehicle traveling on the road independently of driving operations by the vehicle occupant in the autonomous driving mode;
in a case in which the acquired driving mode is the autonomous driving mode, detecting a driving operation intervention by the vehicle occupant;
when the driving operation intervention is detected, stopping a driving assistance function related to an operating device by which the driving operation intervention was detected; and
when the driving operation intervention is detected, displaying a warning image related to the operating device on a display provided inside a vehicle cabin of the vehicle,
displaying speed marks at the display, a spacing of the speed marks changing in accordance with a speed of the vehicle,
in a case in which an accelerator operation for the vehicle is detected, hiding display of the speed marks, and
when the speed of the vehicle is a first speed, displaying the speed marks with a first spacing, and when the speed of the vehicle is a second speed, that is higher than the first speed, displaying the speed marks with a second spacing that is larger than the first spacing.

10. A non-transitory storage medium storing a program executable by a computer to execute processing comprising:
acquiring information regarding a vehicle indicating which of a manual driving mode or an autonomous driving mode is set as a driving mode in the vehicle, the vehicle traveling on a road via driving operations performed by a vehicle occupant in the manual driving mode, and the vehicle traveling on the road independently of driving operations by the vehicle occupant in the autonomous driving mode;
in a case in which the acquired driving mode is the autonomous driving mode, detecting a driving operation intervention by the vehicle occupant;
when the driving operation intervention is detected, stopping a driving assistance function related to an operating device by which the driving operation intervention was detected; and
when the driving operation intervention is detected, displaying a warning image related to the operating device on a display provided inside a vehicle cabin of the vehicle;
displaying speed marks at the display, a spacing of the speed marks changing in accordance with a speed of the vehicle,
in a case in which an accelerator operation for the vehicle is detected, hiding display of the speed marks, and
when the speed of the vehicle is a first speed, displaying the speed marks with a first spacing, and when the speed of the vehicle is a second speed, that is higher than the first speed, displaying the speed marks with a second spacing that is larger than the first spacing.

11. The vehicle display control device according to claim 1 ,
wherein at least in a case in which the acquired driving mode is the autonomous driving mode, display vicinity information depicting an environment around the vehicle on the display provided in the vehicle cabin; and
in a case in which the driving operation intervention is detected, change background information of the vicinity information and display the changed background information on the display.

12. The vehicle display control device according to claim 11 , wherein an area of the background information on the display includes a portion outside of the road on which the vehicle travels, and extends to edges of the display, and
wherein the background information encloses visual representations of the vehicle and the road on which the vehicle travels.

13. The vehicle display control device according to claim 12 , wherein a color of the background information displayed on the display is changed in the case in which the driving operation intervention is detected.
