Abstract With the development of Connected Vehicle, various of on-board applications and functions rely on stable, reliable and fast-response wireless connections furtherly, making it more urgent and widespread for vehicles to be equipped with relevant antenna systems such as positioning and communication. There are many types of vehicle antenna systems, together with a wide range of installation locations and a complex electronic environment which brings a huge challenges to the development of antenna manufacturers and the matching of automobile OEMs. In order to carry out the R&D, matching and testing of the vehicle antenna system better, various parties have proposed a multi-dimensional test and evaluation methods, but there is still a lack of horizontal evaluation between them. This paper analyses the requirements of automotive antenna system evaluation, sorts out and compares the technical paths of various common solutions, summarizes the characteristics and differences of various solutions, and provides a research foundation for further optimizing the vehicle-level antenna system test and evaluation program.

New Knowledge

The use of Piagetian tasks to study logical thinking has continued at a high rate despite the fact that their inherent limitations reduce the probability of finding new knowledge. In this study a microcomputer system was programmed with Piagetian tasks in an attempt to gain advantages while avoiding the limitations of the original tasks. College students viewed tasks in the form of alphanumerics and graphics on a TV monitor and interacted with the tasks by way of a keyboard. All key depressions and times between depressions were recorded on floppy disks which were subsequently interfaced with the IBM/370 computer for data manipulation and analysis. After a two-year test and evaluation program, which involved 360 students in three experiments, these investigators found that the microcomputer system contained several advantages over the original Piagetian tasks and provided the researcher with many new alternatives in the study of logical thinking.

When developing a new manufacturing system or reconfiguring an existing system, it is desirable to have a simulation model for test and evaluation. However, there is often a disconnect between the real system and the simulation model; it is difficult for them to have exactly equivalent behavior. The highest-fidelity “model” is always the system itself. In this paper we propose a framework in which modular models of the manufacturing system components (robots, machines, conveyors, controllers) can be interchanged with their real counterparts, forming a hybrid process. We focus on both the connections between components and the most pertinent aspects of the processed parts. The transfer of parts between the real and virtual domains is particularly challenging; we describe how parts can transition between real and virtual without making substantial changes to the system itself. We discuss how the proposed hybrid process simulation can be used for the design of new manufacturing systems. As the new machines and components are built and installed, they can be “swapped” in for the virtual machines, and testing can be done incrementally. We also discuss how the proposed hybrid process simulation can be used for the upgrade or reconfiguration of existing manufacturing systems. When a new machine or cell is added, or the part flow is reconfigured, the relevant new parts of the system can first be built in simulation and tested as part of the hybrid process, with the new machines. A case study describing the implementation of the hybrid process simulation on the Reconfigurable Factory Testbed at the University of Michigan is presented.
