  • Publication number: 20230227061
    Abstract: Techniques for improving the performance of an autonomous vehicle (AV) are described herein. A system can determine a plan for the AV in a driving scenario that optimizes an initial cost function of a control algorithm of the AV. The system can obtain data describing an observed human driving path in the driving scenario. Additionally, the system can determine for each cost dimension in the plurality of cost dimensions, a quantity that compares the estimated cost to the observed cost of the observed human driving path. Moreover, the system can determine a function of a sum of the quantities determined for each cost dimension in the plurality of cost dimensions. Subsequently, the system can use an optimization algorithm to adjust one or more weights of the plurality of weights applied to the plurality of cost dimensions to optimize the function of the sum of the quantities.

  • Patent number: 8478642
    Abstract: A system method and device for predicting navigational decision-making behavior is provided. The location of a device is used to generate the current location of the device, and a history of past locations of the device. A behavior predicting application predicts the route a drive is going to travel based on driver preferences, such as left-hand turns, avoidance of bridges, etc., as well as the preferred destinations and/or routes traveled in the past. The preferences of a particular driver can be learned by the system to be implemented in the behavior predicting application, or manually input by the driver. The system can employ GPS or other positioning technology to determine the location of the device. The device can be a standard GPS-enabled in-car device, or other portable device such as a cell phone or PDA.
