It is worth mentioning that this differentiation does not mean that it is unprofitable, and cross-border technology has already “layed the groundwork” for automobiles. For example, high-end mobile phone chips can solve safety problems through technical improvement or plug-in MCU (Micro Control Unit) solutions. and computing power, and OTA (Online Upgrade) technology extends the life cycle of the underlying hardware as much as possible to reduce R&D and upgrade costs. Roland Berger believes that the value enhancement of hardware and software brought about by changes in electronic and electrical architecture will be significantly higher than pure IVI (vehicle infotainment) systems and Connectivity (interconnectivity) systems. Among them, the cockpit domain controller and basic software (such as OS) will become the high value of the next five years.
