Driving support device, driving support method and program

Claims

1. an acquisition unit that acquires object information for each lane in a predetermined road section; a calculation unit that calculates a recommendation level for each lane for a vehicle that has a function of switching between an autonomous driving mode and a non-autonomous driving mode based on the object information; and a transmitter that transmits driving support information indicating the recommendation level for each lane; A driving assistance device comprising:

2. the transmitting unit transmits the driving support information to the vehicle; The driving support device according to claim 1 , wherein the vehicle that receives the driving support information selects either an autonomous driving mode or a non-autonomous driving mode based on the recommendation level for each lane.

3. a route calculation unit that calculates candidate driving routes based on a current location of the vehicle and a destination of the vehicle; a transmission unit that transmits the calculated driving route to the vehicle; 2. The driving assistance device according to claim 1, wherein when a driving route including a section in which the recommendation level of all lanes is equal to or lower than a predetermined threshold is transmitted, a predetermined terminal is notified of this.

4. Further, an evaluation unit is provided that evaluates whether the travel route satisfies a condition that the plurality of vehicles do not simultaneously travel through a section with a recommendation level equal to or lower than a predetermined threshold value, The driving assistance device according to claim 3 , wherein the notification unit notifies the predetermined terminal when the driving route does not satisfy the condition.

5. When the evaluation unit is unable to generate a travel route that satisfies the condition, the evaluation unit instructs the route calculation unit to change the travel route of at least one vehicle. The driving assistance device according to claim 4.

6. The driving assistance device according to claim 1 , further comprising a route calculation unit that calculates a driving route to a destination for which a lane is specified based on the recommendation level for each lane.

7. The driving support device according to claim 6, further comprising: when a driving route including a section in which the recommendation level of all lanes is equal to or lower than a predetermined threshold value is transmitted, a predetermined terminal is notified of this.

8. The driving assistance device according to claim 1 , wherein the transmission unit transmits the recommendation level for each lane in a map format that indicates the level of recommendation level for each lane.

9. Obtaining object information for each lane of a predetermined road section; Calculating a recommendation level for each lane for a vehicle having a function of switching between an autonomous driving mode and a non-autonomous driving mode based on the object information; transmitting the recommendation level for each lane to the vehicle entering the predetermined road section; Driving assistance method.

10. A process of acquiring object information for each lane of a predetermined road section; A process of calculating a recommendation level for each lane for a vehicle having a function of switching between an autonomous driving mode and a non-autonomous driving mode based on the object information; a process of transmitting the recommendation level for each lane to the vehicle entering the predetermined road section; A program that executes the following.
