This document discusses plans for unifying in-vehicle systems (IVS) in Russia, including the ERA-GLONASS emergency response system, fleet management systems, road tolling systems, and digital tachographs. The goals are to reduce costs by eliminating redundant hardware and functions across different IVS, standardize interfaces and communication protocols, and develop a single "connected IVS" approach. Key steps include developing standards for IVS/backend communication, regulations around unified use of GNSS data, and software/test tools to validate a reference implementation of unified protocols. Unifying these systems could lower total IVS costs per vehicle by at least 40% according to estimates.
