AUTOSAR from introduction to mastery 100 lectures (87) - key weapon of advanced EEA - AUTOSAR and DDS

Driven by consumers' demand for automatic driving and Internet connection , And the technological leap in communication bandwidth and original computing power , The automotive industry is undergoing rapid transformation . These changes require architectural changes in automotive design , Because the traditional electrical / The electronic architecture cannot provide the necessary scalability for the new data center method required to run the future automotive software system interconnection system .

AUTOSAR and DDS Are two software standards that can meet these new requirements .AUTOSAR It's for cars ecu Designed standardized automobile open system architecture .AUTOSAR Two platforms AUTOSAR Classic and AUTOSAR Adaptive It provides a layered software architecture method for different vehicle use cases . especially ,AUTOSAR Adaptive The design of the in car computing platform solves the challenge of high performance , Solve the connectivity and continuous software updates required by the next generation of vehicles . It can also be used as an integration platform for software from multiple suppliers .

Data distribution services (DDS) The standard is the middleware protocol that integrates the components of the distributed system and the data centric connection framework . It realizes low latency data connection 、 High reliability and scalable flexible architecture , Make data the center of the future mobile digital platform .DDS Promotes loose coupling 、 Development of modular and open architecture systems , This reduces complexity 、 Time to market and system cost .

In order to meet the needs of interconnected digital vehicles ,AUTOSAR and DDS These two powerful standards can now work together . stay AUTOSAR Adaptive In the platform ,DDS The component is optimized for end-to-end data sharing , No need for custom integration .AUTOSAR Adaptive Defined DDS network building , To support autonomous systems with a production ready communication framework , The framework provides the reliability required by complex systems 、 Scalability and performance .AUTOSAR and DDS Together, it provides automobile manufacturers with high-performance methods for designing and operating the next generation of vehicles .

Digital Internet connected vehicle

Driven by consumer demand for continuous connectivity and data-driven technologies , The automotive industry is in a state of disruptive change , These technologies are driving connected cars 、 Autopilot 、 Sharing and digital services and the progress of electric vehicles . Manufacturers and suppliers must meet the challenges of building interconnected digital vehicles . The cars of the future must be designed to run in different real-time environments 、 Interoperability with other systems in the vehicle 、 Connect to the off vehicle system and provide built-in vehicle level network security and functions
