Abstract
The maximum speed informing device includes a camera device that acquires image data by capturing a scene in front of the vehicle, a display unit configured to be able to display the maximum speed, and a controller configured to be able to change the maximum speed displayed on the display unit, the controller acquires a numerical value included in the captured scene as a maximum speed candidate based on the image data, acquires road structure information indicating a structure of a road including a lane on which the vehicle is traveling based on the image data, estimates a range of a maximum speed of the road based on the acquired road structure information, and displays the maximum speed candidate within the estimated maximum speed range as the maximum speed on the display unit.
Claims5
A maximum speed informing device comprising:
- a camera device that acquires image data by capturing a scene ahead of a vehicle;
- an informing unit configured to be able to provide information to a driver of the vehicle;
- and
- a controller configured to be able to change the information provided from the informing unit, wherein the controller is configured to:
- acquire numerical values included in the captured scene as maximum speed candidates based on the image data;
- acquire road structure information that indicates a structure of a road on which the vehicle is traveling based on the image data;
- estimate a maximum speed range as a possible range of a maximum speed set for the road based on the acquired road structure information;
- and
- cause the informing unit to indicate a candidate within the estimated maximum speed range, among the maximum speed candidates, as the maximum speed set for the road.
A maximum speed informing method comprising:
- acquiring image data by capturing a scene ahead of a vehicle using a camera device;
- acquiring numerical values included in the captured scene as maximum speed candidates based on the image data;
- acquiring road structure information that indicates a structure of a road on which the vehicle is traveling based on the image data;
- estimating a maximum speed range as a possible range of a maximum speed set for the road based on the acquired road structure information;
- and
- causing an informing unit to indicate a candidate within the estimated maximum speed range, among the maximum speed candidates, as the maximum speed set for the road.
A non-transitory storage medium storing a program to be executed by a computer mounted on a vehicle, the program causing the computer to execute a process comprising:
- acquiring image data by capturing a scene ahead of a vehicle using a camera device;
- acquiring numerical values included in the captured scene as maximum speed candidates based on the image data;
- acquiring road structure information that indicates a structure of a road on which the vehicle is traveling based on the image data;
- estimating a maximum speed range as a possible range of a maximum speed set for the road based on the acquired road structure information;
- and
- causing an informing unit to indicate a candidate within the estimated maximum speed range, among the maximum speed candidates, as the maximum speed set for the road.
