Abstract: In some examples, a service computing device receives, from a vehicle computing device onboard a vehicle, a communication including sensor data obtained from at least one sensor onboard the vehicle. Based on the communication, the service computing device determines a transmission delay corresponding to a difference between a time when the vehicle sent the communication and a time when the communication was received. Based on the communication, the service computing device determines a trajectory of the vehicle on a travel route. Based on the sensor data, transmission delay, wind direction and magnitude, surrounding objects, and trajectory, the service computing device determines vehicle control information for the vehicle. The service computing device sends, to the vehicle, based at least on the vehicle control information, at least one instruction causing the vehicle to perform at least one control operation for traversing one or more locations associated with the trajectory of the vehicle.

Abstract: In some examples, a system receives sensor data from sensors on board a vehicle. Based at least on the sensor data indicating an anomaly has occurred and is affecting a travel path of the vehicle, an uncertainty threshold is compared with an uncertainty value associated with a prediction model. For instance, the uncertainty value may be indicative of a difference between a predicted value predicted by the prediction model and an actual measured value related to at least one operation parameter of the vehicle. Based at least on determining that the anomaly has occurred and that the uncertainty value is within the uncertainty threshold, sending, by the system, a communication for obtaining an updated prediction model.

Abstract: In some examples, a system may receive, from at least one camera of a vehicle, at least one image including a road. The system may further receive vehicle location information including an indication of a location of the vehicle. In addition, the system may receive at least one of historical information from a historical database, or road anomaly information, where the road anomaly information is determined from at least one of a road anomaly database or real-time road anomaly detection. Based on the at least one image, the indication of the location of the vehicle, and the at least one of the historical information or the road anomaly information, the system may generate at least one of a disparity map or a disparity image.
