Abstract

Systems and methods described herein relate to controlling the operation of a vehicle. One embodiment generates predicted trajectories of the vehicle using first trajectory predictors based, at least in part, on first inputs; generates predicted trajectories of a road agent that is external to the vehicle using second trajectory predictors based, at least in part, on second inputs; integrates the predicted trajectories of the road agent into the first inputs to iteratively update the predicted trajectories of the vehicle and integrates the predicted trajectories of the vehicle into the second inputs to iteratively update the predicted trajectories of the road agent; and controls operation of the vehicle based, at least in part, on at least one of (1) the iteratively updated predicted trajectories of the vehicle and (2) the iteratively updated predicted trajectories of the road agent.
