Abstract

A remote function selection device selects a remote function in an automated drive vehicle configured to execute automated drive and remote travel and provided with a plurality of remote functions. The remote function selection device is configured to determine whether executing the automated drive at a predetermined timing is impossible; determines the remote function that is executable at the predetermined timing when it is determined that executing the automated drive is impossible; predict an action of a target around the automated drive vehicle based on a detection result from an external sensor configured to detect the target; calculate an action prediction confidence degree for the predicted action of the target; and selects the remote function. The remote function selection device configured to select the remote function based on the calculated action prediction confidence degree when it is determined that a plurality of remote functions is executable.

First claim

What is claimed is:

1 . A remote function selection device configured to select a remote function to be executed in an automated drive vehicle configured to execute automated drive and remote travel in which the automated drive vehicle travels based on a remote instruction from a remote operator, the automated drive vehicle being provided with a plurality of remote functions for performing the remote travel, the remote function selection device comprising:
an automated drive determination unit configured to determine whether executing the automated drive at a predetermined timing is impossible; a remote function determination unit configured to determine the remote function that is executable at the predetermined timing when the automated drive determination unit determines that executing the automated drive is impossible; a confidence degree calculation unit configured to predict an action of a target around the automated drive vehicle based on a detection result from an external sensor configured to detect the target calculate an action prediction confidence degree for the predicted action of the target; and a function selection unit configured to select the remote function to be executed, wherein when the remote function determination unit determines that a plurality of remote functions is executable, the function selection unit configured to select the remote function to be executed among the remote functions based on the action prediction confidence degree calculated by the confidence degree calculation unit.

2 . The remote function selection device according to claim 1 , wherein the function selection unit is configured to select the remote function that occupies the remote operator for a long time when the action prediction confidence degree is low, compared to when the action prediction confidence degree is high.

3 . The remote function selection device according to claim 1 , further comprising a distance calculation unit configured to calculate a relative distance between the target and the automated drive vehicle, wherein
the function selection unit is configured to select the remote function to be executed among the remote functions determined by the remote function determination unit, based on the action prediction confidence degree and the relative distance.

4 . The remote function selection device according to claim 3 , wherein the function selection unit is configured to select the remote function that occupies the remote operator for a short time when the relative distance is long, compared to when the relative distance is short.

5 . The remote function selection device according to claim 1 , wherein the remote functions include remote assist and remote drive.

6 . A remote function selection device configured to select a remote function to be executed in an automated drive vehicle configured to execute automated drive and remote travel in which the automated drive vehicle travels based on a remote instruction from a remote operator, the automated drive vehicle being provided with a plurality of remote functions for performing the remote travel, the remote function selection device comprising a processor configured to:
determine whether executing the automated drive at a predetermined timing; determine the remote function that is executable at the predetermined timing when the processor determines that executing the automated drive is impossible; predict an action of a target around the automated drive vehicle based on a detection result from an external sensor configured to detect the target; calculate an action prediction confidence degree for the predicted action of the target; select the remote function to be executed; and when the processor determines that a plurality of remote functions is executable, select the remote function to be executed among the remote functions, based on the calculated action prediction confidence degree.

7 . The remote function selection device according to claim 6 , wherein the processor is configured to select the remote function that occupies the remote operator for a long time when the action prediction confidence degree is low, compared to when the action prediction confidence degree is high.

8 . The remote function selection device according to claim 6 , wherein the processor is configured to
calculate a relative distance between the target and the automated drive vehicle, and select the remote function to be executed among the remote functions based on the action prediction confidence degree and the relative distance.

9 . The remote function selection device according to claim 8 , wherein the processor is configured to select the remote function that occupies the remote operator for a short time when the relative distance is long, compared to when the relative distance is short.

10 . The remote function selection device according to claim 6 , wherein the remote functions include remote assist and remote drive.
