1. A system for resolving information contradictions in information received by a vehicle, the system comprising:
a plurality of vehicle sensors for receiving the information, wherein the plurality of vehicle sensors includes at least a camera;
a controller in electrical communication with the plurality of vehicle sensors, wherein the controller is programmed to:
determine a first piece of information using a first of the plurality of vehicle sensors;
determine a second piece of information using a second of the plurality of vehicle sensors;
determine a contradiction status between the first piece of information and the second piece of information, wherein the contradiction status includes a contradicting status and a non-contradicting status;
construct if-then clauses from one of the first piece of information and the second piece of information in response to determining that the contradiction status is the contradicting status;
determine a third piece of information using a third of the plurality of vehicle sensors in response to determining that the contradiction status is the contradicting status, wherein the third of the plurality of vehicle sensors is the camera, and wherein the third piece of information includes an image of an environment surrounding the vehicle;
resolve a contradiction between the first piece of information and the second piece of information to determine a true piece of information by evaluating the if-then clauses using a visual question answering algorithm based on the third piece of information in response to determining that the contradiction status is the contradicting status, wherein the true piece of information is one of: the first piece of information and the second piece of information; and
adjust an operation of the vehicle based on the true piece of information in response to resolving the contradiction.
