With the development of autonomous driving and new energy vehicles, the requirements for electronic and electrical architecture are getting higher and higher, and the requirements for its intelligence, diversification and flexibility are getting higher and higher. On this basis, Anbofu A new concept is proposed - an intelligent electronic and electrical architecture. In the "China Automotive Electronic and Electrical Architecture Technology Innovation and Development Forum 2018", Mr. Yu Ning, Director of Product Engineering, APTIV Asia Pacific, attended the conference and gave a wonderful speech. Yu Zong gave us detailed answers on what is the electrical and electronic architecture, the current demand for electronic and electrical architecture of vehicles and future vehicles, and the new concept and development side of Anbofu's intelligent electronic and electrical architecture.
What is an electrical and electronic architecture? The electronic and electrical architecture contains all the hardware, software, sensors, actuators, and electronic and electrical distribution systems on the vehicle. The electronic and electrical architecture integrates all of this content through system integration tools. It contains the most software facilities and hardware. The three basic elements of the facility and efficient power and signal distribution system are based on a combination of software facilities and hardware facilities, and an efficient power and signal distribution system that organically combines these software and hardware. The current electronic and electrical architecture not only needs to meet the functions of the vehicle itself and the service of the vehicle itself, but also extends to the cloud to realize the interconnection between the vehicle and the vehicle, the interconnection between the vehicle and the transportation facilities, and the interconnection between the vehicle and the person. These will be realized through the electronic and electrical architecture, so the future electronic and electrical architecture is an interconnected electronic and electrical architecture.
With the development of intelligent vehicles and the development of new energy vehicles, the requirements for electronic and electrical architectures will become higher and higher. With the continuous improvement of user experience systems, entertainment systems, interactive systems and active safety functions, the current electronic and electrical architecture These requirements have not been met, and the current electronic and electrical architecture has not enough space and corresponding cost increase, and there are also great difficulties in physical installation. If you want to continue to meet the corresponding functions of autonomous driving and new energy vehicles, the current architecture has exceeded the load and the current architecture needs to be updated.
Afterwards, Mr. Yu explained the intelligent electronic and electrical architecture of Anbofu to the guests. It is mainly composed of the brain and nervous system. The brain is mainly composed of three supercomputers, including an autopilot supercomputer, a central location sensor supercomputer, and a network-side security supercomputer; it is responsible for all the data, operations, and instructions issued to make the next move. The nervous system is divided into two parts: the power transmission system and the data transmission system: the power transmission system is used to transmit power, and all the required power of the vehicle is transmitted to the appropriate actuator in a suitable manner to perform the operation we want. The data transmission system is used to transmit data. The current car will generate a huge amount of data. This massive amount of data needs a reliable transmission system to transmit, and it needs a stable, reliable and anti-interference transmission system. Time passes the data to the exact location in an accurate manner.
Therefore, we must make an overall consideration of the vehicle's electrical and electronic architecture, including hardware, software, and power signal distribution systems. For this intelligent automotive electronic and electrical architecture system: First, there must be great flexibility. Its software facilities and hardware facilities must have relative flexibility. It can continuously update software. It is a function that keeps the car extended. An architecture; the second must have a good extension, to separate the software and hardware throughout the life cycle, on the basis of hardware and software can be continuously updated, constantly download new applications, let the whole The functions of the trolley continue to expand; the most important is reliability, including system fault tolerance, system redundancy, multi-layer security, even a few seconds of failure for the entire vehicle, for the entire vehicle Human security is a huge disaster.
Finally, Mr. Yu introduced the redundancy setting of the third layer of Anbofu to the guests: the reliability of the first central processor, the three supercomputers can complement each other and work together. If one of the computers fails, the other two The computer can temporarily take over the work of this computer to ensure that the car can be safely driven to a safe place. The security of the second network ensures that the car can drive the car to a safe place through backup and three supercomputers in the event of network problems. The management of the third energy, energy dual system backup, so that the car will not lose the ability of the entire car due to the loss of energy in a certain link. Through these three settings, the safety and reliability of the car are fully guaranteed.
