Abstract: The electronic map of the advanced driving assistance system (ADAS) extracts slope, curvature, heading and other data from map data, and provides necessary road traffic environment perception information for active safety and assisted driving through comprehensive decisionmaking. This article through the development process of ADAS electronic map products described, clear its design stage, especially to pay attention to the hardware positioning module selection and software in the electronic horizon provider (EHP) parser algorithm selection specific requirements, at the same time the software and hardware need to have a reasonable computing power of the system on chip (SoC), with filtering global positioning system (GPS) positioning information and location information backtracking function to make clear requirements. Product hardware through functional testing, bench testing, real vehicle road testing to its system network performance and key functions of a comprehensive verification.
