Action planning device having a trajectory generation and determination unit
Vehicle systems that implement action planning for a vehicle have had difficulty in maintaining safety in the event of a failure in a recognition device since these systems generate trajectories and control the vehicle on the basis of outside-world information recognized by recognition devices. The present invention was conceived in light of the aforementioned situation and addresses the problem of maintaining safety even in the event of a failure in a recognition device of a vehicle system. This problem can be solved by an action planning device having a failure detection unit for detecting a failure in an outside-world recognition unit and a trajectory generation/determination unit for executing an action on the occurrence of a failure on the basis of outside-world information outputted by the outside-world recognition unit, wherein the trajectory generation/determination unit takes an action for coping with the failure on the basis of failure information from the failure detection unit.
1. An action planning device, comprising:
a failure detection unit that is configured to: i) detect an occurrence of a failure in outside-world recognition units, and ii) issue a notification;
an integration recognition unit that is configured to: i) integrate outside-world recognition information output from the outside-world recognition units, and ii) output integration recognition information; and
a trajectory generation/determination unit that is configured to send, to a drive unit, a control instruction to execute an action on the occurrence of the failure, on the basis of the integration recognition information output by the integration recognition unit, wherein
the trajectory generation/determination unit is configured to send an instruction to take an action that addresses the failure, on the basis of the notification of the failure detection unit,
the trajectory generation/determination unit is configured to generate a vehicular trajectory that addresses the failure to enter a safe state, based on past outside-world recognition information of moving objects and of stationary objects, and
the past outside-world recognition information, in which the failure occurs, and a recognition result of a recognition device, in which no failure occurs, are configured to be displayed in such a manner that they are superimposed one over the other.
2. The action planning device according to claim 1 , wherein the trajectory generation/determination unit is configured to determine a failure occurrence time, and is configured to discard outside-world recognition information after the failure occurrence time.
3. The action planning device according to claim 1 , further comprising:
a notification unit that is configured to notify of the occurrence of the failure.
4. The action planning device according to claim 1 , wherein the integration recognition unit is configured to predict an approach of a dynamic object based on a physical limit value or a road traffic law.
5. The action planning device according to claim 1 , wherein the trajectory generation/determination unit is configured to generate the vehicular trajectory.
6. The action planning device according to claim 1 , wherein the trajectory generation/operation unit is configured to maintain a middle state of a traffic lane as a safe state.

10. The action planning device according to claim 8 , further comprising:
a notification unit that is configured to notify of the occurrence of the failure.
11. The action planning device according to claim 8 , wherein the integration recognition unit is configured to predict an approach of a dynamic object based on a physical limit value or a road traffic law.
