Abstract: A system establishes a first network communication path with a first base station. The system detects a first cellular information associated with a first network provider based on the first network communication path. The first cellular information indicates cellular coverage provided by the first network provider along a road. The system establishes a second network communication path with a second base station. The system detects a second cellular information associated with a second network provider based on the second network communication path. The second cellular information indicates cellular coverage provided by the second network provider along the road. The system establishes a third network communication path with a remote server and detects network information based on the third network communication path. A network coverage map along the road is generated based on the network information, the first and second cellular information.

Abstract: The system and method make it feasible to develop an autonomous vehicle control system for complex vehicles, such as for cargo trucks and other large payload vehicles. The method and system commence by first obtaining 3-dimensional data for one or more sections of roadway. Once the 3-dimensional roadway data is obtained, that data is used to run computer simulations of a computer model of a specific vehicle being controlled by a generic vehicle control algorithm or system. The generic vehicle control algorithm is optimized by running the simulations utilizing the 3-dimensional roadway data until an acceptable performance result is achieved. Once an acceptable simulation is executed using the generic vehicle control algorithm, the control algorithm/system is used to run one or more real-world driving tests on the roadway for which the 3-dimensional data was obtained. Finally, the computer model for the vehicle is modified.
