Abstract

An enhanced map information processing unit 14 of a driving assistance device 1 acquires from a determination unit 13 information on surroundings of a vehicle which is needed to perform autonomous driving, and acquires from a server device 2 environment information on surroundings of a route on which autonomous driving is performed. On the basis of the acquired environment information, the enhanced map information processing unit 14 extracts, as an autonomous driving unsuitable location Pn, a location at which the accuracy of the acquirement of the sensor unit 12 is predicted not to satisfy a standard for acquiring the information on the surroundings of the vehicle needed to perform autonomous driving. An informing unit 18 alerts the extracted autonomous driving unsuitable location Pn to a user.

Claims (29)

1. A route search device comprising:

a sensor acquiring information associated with surroundings of a moving body; and

a processor configured to:

search for or estimate a moving route of the moving body;

acquire environment information on surroundings of the moving route; and

provide information indicating that the moving route has been modified, based on the environment information on the surroundings, to avoid a section or a point on which autonomous driving by the sensor is unsuitable.

2. The route search device of claim 1 , wherein the section or the point on which autonomous driving is unsuitable comprises at least one of:

a section having rainfall or snow fall higher than a standard value, a road surface freezing, or heavy fog that does not meet a standard accuracy;

a section having no detectable marks such as a road white line, a sign, or a building for a sensor to perform autonomous driving; and

a section where another vehicle previously operated and could not perform autonomous driving.

3. A route search device comprising:

a sensor acquiring information on surroundings of a moving body; and

a processor configured to:

search for or estimate a moving route where the moving body moves;

acquire environment information on surroundings of the moving route searched for or estimated by the route search unit; and

inform a user of the moving route,

wherein the processor is further configured to, based on the environment information, search for or estimate the moving route avoiding a section or a point on which performing autonomous driving by use of the sensor is unsuitable.

4. The route search device of claim 3 , wherein the moving route comprises a first moving route where the moving body moves, and the processor is configured to, based on the environment information, search for or estimate a second moving route avoiding a section or a point which is on the first moving route and on which performing autonomous driving by use of the sensor is unsuitable.

5. The route search device according to claim 3 ,

wherein the moving route is modified by the processor to avoid a section or a point on at least one of a compartment line, a sign and a structure is not detectable by the sensor.

6. The route search device of claim 3 , wherein the section or the point on which performing autonomous driving by use of the sensor is unsuitable comprises at least one of:

a section having rainfall or snow fall higher than a standard value, a road surface freezing, or heavy fog that does not meet a standard accuracy;

a section having no detectable marks such as a road white line, a sign, or a building for a sensor to perform autonomous driving; and

a section where another vehicle previously operated and could not perform autonomous driving.

7. A route search method executed by a route search device, comprising:

acquiring information associated with surroundings of a moving body;

searching for or estimating a moving route of the moving body;

acquiring environment information on surroundings of the moving route; and

informing a user by providing information indicating that the moving route has been modified, based on the environment information on the surroundings, to avoid a section or a point on which autonomous driving by the sensor is unsuitable.
