Abstract: An autonomous vehicle, system and method of operating the autonomous vehicle. The system includes an episodic memory, a hyper-association module and a navigation system. The episodic memory stores a plurality of episodes, recalls a plurality of candidate episodes in response to receiving a partial prefix and recalls a hypothesis episode in response to receiving an intermediate episode. The hyper-association module receives the plurality of candidate episodes from the episodic memory and obtains the intermediate episode from the plurality of candidate episodes. The navigation system navigates the autonomous vehicle using the hypothesis episode.

Abstract: An autonomous vehicle, system and method of operating the autonomous vehicle. The system includes a performance evaluator, a decision module and a navigation system. The performance evaluator determines a performance grade for each of a plurality of decisions for operating the autonomous vehicle. The decision module selects a decision have a greatest performance grade. The navigation system operates the autonomous vehicle using the selected decision.

Abstract: An automotive vehicle includes an actuator configured to control vehicle acceleration, steering, or braking. The vehicle additionally includes at least one sensor configured to detect an object in the vicinity of the vehicle. The vehicle further includes at least one controller configured to automatically control the actuator according to an automated driving system algorithm. The at least one controller is configured to define a first vehicle route, detect at least one object in the vicinity of the vehicle; calculate a probabilistic forecast of a future location of the at least one detected object, define a second vehicle route in response to the probabilistic forecast indicating proximity of the at least one detected object to the first route, and to control the actuator to execute the second vehicle route.

Abstract: The present application generally relates to methods and apparatus for evaluating and assigning a performance metric to a driver response to a driving scenario. More specifically, the application teaches a method and apparatus for breaking a scenario into features, assigning each feature a grade and generating an overall grade in response to a weighted combination of the grades.
