Abstract

Abstract:

At present， intelligent vehicle has become the strategic development direction of the global automotive industry. The core of automotive technology and engineering is shifting from traditional hardware layer to software layer. Software defined vehicle （SDV） has become an important trend of automotive development in future. By comparing SDV with traditional vehicle， the development， the physical structure and the cyber structure as well as the technical system of SDV are proposed in this paper.

Key words: software defined vehicles, technical system, vehicle development, vehicle physical structure, vehicle cyber structure
