Abstract: Various technologies described herein pertain to routing autonomous vehicles based upon spatiotemporal factors. A computing system receives an origin location and a destination location of an autonomous vehicle. The computing system identifies a route for the autonomous vehicle to follow from the origin location to the destination location based upon output of a spatiotemporal statistical model. The spatiotemporal statistical model is generated based upon historical data from autonomous vehicles when the autonomous vehicles undergo operation-influencing events. The spatiotemporal statistical model takes, as input, a location, a time, and a direction of travel of the autonomous vehicle. The spatiotemporal statistical model outputs a score that is indicative of a likelihood that the autonomous vehicle will undergo an operation-influencing event due to the autonomous vehicle encountering a spatiotemporal factor along a candidate route.

Abstract: Various technologies described herein pertain to detecting data in a lidar point cloud representative of vapor and controlling an autonomous vehicle based on such detection. The lidar point cloud is outputted by a lidar sensor system of the autonomous vehicle. The techniques set forth herein utilize dual return lidar data outputted by the lidar sensor system. The dual return lidar data includes two lidar returns received responsive to a light beam emitted (e.g., at a particular azimuthal angle) by the lidar sensor system into a driving environment of the autonomous vehicle. The data in the lidar point cloud detected as being caused by vapor can be removed from downstream processing; accordingly, the autonomous vehicle can be controlled such that the autonomous vehicle need not stop for or maneuver around vapor in the driving environment.

Abstract: Restrictions at launch-time can ensure that specific types of AV stacks are launched and ensure the software release is launched only during certain times. Restrictions at runtime can ensure that certain operations are prohibited while the software release is running on the autonomous vehicle. Enforcing restrictions at launch-time and runtime is not trivial. A schema can be used to encode the restrictions. Restrictions may be included in a manifest of the software release. The manifest having the restrictions can be cryptographically signed. Components can be implemented to verify and enforce these restrictions on the AV. As a result, more kinds of restrictions and more complex restrictions can be applied for software releases for the AV.

Abstract: Apparatus and techniques for analyzing a capacitance value in an electric motor inverter are disclosed. A processor is coupled to a DC-AC inverter, which includes a capacitor across its terminals and is powered by a battery. The processor performs resistor switching to enable singular, periodic measurement of the capacitance. The measured value is compared with a nominal or beginning of life (BOL) value. An alert may be sent if the capacitance has degraded beyond a threshold. In other aspects, the DC torque ripple envelop is used to measure capacitance. The outcome is compared with the other tests to assess consistency. An inconsistent outcome may identify potential resistor degradation.
