Vehicle remote instruction system
A vehicle remote instruction system includes a remote instruction point situation recognition unit that recognizes a remote instruction point situation on a target route based on the target route, position information, and map information, a recommended time acquisition unit that acquires a recommended time based on the remote instruction point situation and a type of a remote instruction, a remote instruction sending unit that sends the remote instruction to an autonomous driving vehicle, and a predicted time calculation unit that calculates a predicted time. The remote instruction sending unit sends a delay instruction to set a reflection time closer to the recommended time when the predicted time is earlier than the recommended time, and sends a preparation instruction to cause the autonomous driving vehicle to behave in response to the type of the remote instruction at an earlier time when the predicted time is later than the recommended time.
1. A vehicle remote instruction system in which a remote instruction for controlling an autonomous driving vehicle is sent, the vehicle remote instruction system comprising:
a remote instruction point situation recognition unit configured to recognize a remote instruction point situation on a target route of the autonomous driving vehicle based on the target route that is set in advance, position information on the autonomous driving vehicle, and map information;
a recommended time acquisition unit configured to acquire a recommended time, the recommended time being set in advance with a predetermined time from a start to an end of the remote instruction point situation as a reference point based on the remote instruction point situation and a type of the remote instruction;
a remote instruction sending unit configured to send the remote instruction to the autonomous driving vehicle; and
a predicted time calculation unit configured to calculate a predicted time based on an external environment of the autonomous driving vehicle, the type of the remote instruction, and an instruction time of the remote instruction, the predicted time being a time at which the remote instruction is predicted to be reflected on the autonomous driving vehicle, wherein:
when the predicted time is earlier than the recommended time, the remote instruction sending unit is configured to send a delay instruction to the autonomous driving vehicle, the delay instruction being an instruction that sets a reflection time closer to the recommended time by setting the reflection time later than the predicted time, the reflection time being a time at which the remote instruction is reflected on the autonomous driving vehicle; or
when the predicted time is later than the recommended time, the remote instruction sending unit is configured to send a preparation instruction to the autonomous driving vehicle, the preparation instruction being an instruction that causes the autonomous driving vehicle to behave in response to the type of the remote instruction at an earlier time.
2. The vehicle remote instruction system according to claim 1 , the vehicle remote instruction system further comprising:
an instruction input unit configured to allow a remote commander to enter the remote instruction according to a situation of the autonomous driving vehicle; and
a commander database configured to store, in advance, commander tendency information in association with the remote commander, the commander tendency information being information regarding whether the remote commander tends to enter the remote instruction earlier than or later than the recommended time, wherein the predicted time calculation unit is configured to calculate the predicted time also based on the commander tendency information.
3. The vehicle remote instruction system according to claim 1 , the vehicle remote instruction system further comprising a communication delay prediction unit configured to predict a communication delay corresponding to the remote instruction point situation based on the map information and the remote instruction point situation, wherein the predicted time calculation unit is configured to calculate the predicted time that includes the communication delay.
