Abstract

A method and device for estimating the operating time of a motor vehicle in autonomous mode for at least one route between a departure point and an arrival point. The estimating device is connected to an identifying element and to an element for characterizing portions of roads approved for the operation of the vehicle in autonomous mode, along the at least one route. The estimating device includes a unit for calculating the time during which the vehicle is eligible to operate in autonomous mode depending on the characterization of approved portions of road.

Claims

1. A server comprising:

circuitry configured to

determine at least one route between a departure point and an arrival point entered by a driver at a user interface of a vehicle,

receive data from an identifying element connected to the server, the data corresponding to recognized approved one or more portions of a road or roads where the vehicle is able to travel in an autonomous driving mode for the determined at least one route,

receive data from a characterizing element connected to the server, the data corresponding to characterizations of the one or more portions of the road or roads approved for operation of the vehicle in the autonomous driving mode, along said determined at least one route,

determine an amount of time during which the vehicle is eligible to operate in the autonomous driving mode based on the characterization of the approved one or more portions of the road or roads approved for operation of the vehicle in the autonomous driving mode, along said determined at least one route, and

output, from the server, data for display at the vehicle of the determined amount of time during which the vehicle is eligible to operate in the autonomous driving mode for said determined at least one route.

2. The server as claimed in claim 1, wherein the data corresponding to characterizations of the one or more portions of the road or roads approved for operation of the vehicle in the autonomous driving mode, along said determined at least one route, is generated by the characterizing element based on a length and a regulatory speed of the approved one or more road portions.

3. The server as claimed in claim 1, wherein the circuitry is configured to communicate with an electronic medium.

4. The server as claimed in claim 1, wherein the circuitry is configured to

receive data from a traffic conditions element connected to the server, the data corresponding to one or more traffic conditions along said determined at least one route, and

determine the amount of time during which the vehicle is eligible to operate in the autonomous driving mode is dependent upon the data corresponding to the one or more traffic conditions.

5. The server as claimed in claim 1, wherein the data output for display at the vehicle is for a display associated with a navigation system of the vehicle.

6. A method comprising:

determining at least one route between a departure point and an arrival point entered by a driver at a user interface of a vehicle;

identifying one or more portions of road approved for operation of the vehicle in an autonomous driving mode, along said determined at least one route;

characterizing the approved one or more portions of road;

estimating an amount of time during which the vehicle is eligible to travel in the autonomous driving mode based on the characterization of the approved one or more portions of road approved for operation of the vehicle in the autonomous driving mode, along said determined at least one route; and

outputting data for display at the vehicle of the estimated amount of time during which the vehicle is eligible to operate in the autonomous driving mode for said determined at least one route.

7. The method as claimed in claim 6, wherein said characterizing the approved one or more portions of road includes acquiring data relating to a length of the approved one or more portions of road and to regulatory speeds thereof.

8. The method as claimed in claim 7, further comprising:

acquiring data relating to traffic conditions along said at least one route,

wherein said estimating the amount of time is dependent upon the data relating to the traffic conditions.

9. The estimating method as claimed in claim 6, further comprising:

concatenating the approved one or more portions of road which are juxtaposed; and

filtering the amount of times estimated for the concatenated one or more portions of road or the approved one or more portions of road when they have not been concatenated.

10. A method comprising:

acquiring a departure point and an arrival point entered by a driver at a user interface of a vehicle;

determining at least one route between the entered departure point and the entered arrival point;

identifying one or more portions of road approved for operation of the vehicle in an autonomous driving mode, along said determined at least one route;

characterizing the approved one or more portions of road;

estimating an amount of time during which the vehicle is eligible to travel in the autonomous driving mode based on the characterization of the approved one or more portions of road approved for operation of the vehicle in the autonomous driving mode, along said determined at least one route; and

outputting data for display at the vehicle of the estimated amount of time during which the vehicle is eligible to operate in the autonomous driving mode for said determined at least one route.
