Next-Generation E/E Architecture for Connected Vehicles

Intelligent connected vehicles are an organic integration of the Internet of Vehicles and intelligent vehicles. Equipped with advanced onboard sensors, controllers, actuators, and other devices and integrating modern communication and network technologies, they achieve safe, comfortable, energy-efficient, and efficient driving through intelligent information exchange and sharing and intelligent human-machine interaction, as a new generation of vehicles with increasingly strong attributes of mobile data centers and consumption spaces.

Technical advantages

Continuous upgrade of in-vehicle high-speed network interconnection bandwidth

Bus processing bandwidth within domain controllers continues to increase

Higher-speed sensor data transmission interfaces

More diverse large displays and consumer interfaces

Test challenges

Lack of familiarity with high-speed buses

Lack of test experience with high-speed serial buses

Diverse interface types and complex test standards

Lack of better debugging means for the full workflow in automotive environments

Tight project schedules require building in-house validation platforms and capabilities
