Abstract: Vehicle dynamics related parameter(s) of an autonomous vehicle model can be calibrated so that the autonomous vehicle model can more accurately determine the driving related behaviors of the autonomous vehicle. An example method comprises obtaining, from sensor data, vehicle related parameters; performing a first determination of a slope of a road and a banking angle of the road based on a pitch angle of the vehicle and a roll angle of the vehicle, respectively; performing a second determination of a set of parameters that describe a driving-related operation of the vehicle; performing a third determination that at least one difference between at least one value from the set of parameters and a corresponding parameter from the plurality of vehicle related parameters exceeds at least one threshold value; and obtaining, in response to the third determination, a calibrated longitudinal dynamic-related parameter or a calibrated lateral dynamic-related parameter.

Abstract: Techniques are described for analyzing autonomous vehicle driving. An example technique includes receiving, by a computer, a set of data from a software that performs driving related operations for an autonomous vehicle; generating a plurality of frames using the timestamps associated with the set of data; determining, for each frame, that the at least one data indicates information related to the autonomous vehicle and/or the one or more objects; assigning, for each frame, a label associated with the information indicated by the at least one data; and displaying, using a graphical user interface (GUI) and for the test performed with the software, at least one label associated with at least one information in a frame.

Abstract: Devices, systems, and methods for controlling a vehicle are described. An example method for controlling a vehicle includes obtaining planning information relating to an intended operation of the vehicle, the intended operation relating to an intended value of an operation parameter of the vehicle; obtaining, based on the intended operation of the vehicle, context information relating to an environment in which the vehicle is to operate following the planning information; determining a context compensated control instruction based on the planning information and the context information; obtaining feedback relating to a deviation of a real-time value of the operation parameter of the vehicle operating according to the context compensated control instruction from the intended value of the operation parameter relating to the intended operation; determining a corrected control instruction based on the feedback; and operating the vehicle based on the corrected control instruction.
