    User experience of the vehicles' telematics services depends on quality of bidirectional network connection between the vehicle and stationary high-performance computing system. In this case, there is a task of ensuring continuous data transmission between the vehicle and stationary computing system in the conditions of highly dynamic networks. The answer is to retrieve data about surrounding networks from external sources. The source may be a telematics map - set of low-level methods, which provide management routines for data about available networks. While vehicle moves along the route, these methods handle the data about surrounding networks, generalize them by geographical and temporal principles, execute queries to a database retrieving list of networks available in the area. As a result, we can schedule connections to wireless networks throughout the route. The article covers technical aspects of implementation of the telematics map information system: data collection and generalization technologies, networks list composition rules. The prototype demonstrates ability to solve the task of networks lists management in moving vehicle under real world radio conditions

    The paper describes development of the methods and algorithm for predicting telematics on the vehicle’s route. De- scribed data management technology on global and local wireless networks, provides methods for managing data on the telematics environment, implemented a prototype of the data management subsystem. The time dependencies of the execution of queries are analyzed depending on the amount of data for the data warehouse on board the vehicle and for the cloud service. The result of the work is recommendations for developing connection management methods in wireless multiprotocol networks on vehicle devices. The paper describes the result of the development and research methods for predicting the telematics environment, for obtaining and analyzing the temporal characteristics of their functioning from global and local telematic maps
