Evolution of Vehicle Architecture


Over time, both vehicles and electrical technology have undergone rapid development and change. Early vehicles relied mainly on mechanical systems, while with the advancement of technology, electrical systems gradually became an integral part of the vehicle. As a result, the amount of data transferred in vehicles is growing rapidly.


In 2018, a car needed to transfer 15,000 pieces of data in the blink of an eye, and by 2020, that number will surge to 100,000 pieces of data.


In response to the growing demand for software functions and higher demands on computing power, the automotive industry needs to constantly innovate and improve its computing solutions.


By taking a closer look at the evolution of electrical architecture systems, we can better understand the reasons and necessity for this shift. At the same time, this also provides new ideas and directions for future automotive development to cope with the growing demand for data transmission and processing, as well as more complex and diverse software functions.

As the capabilities of cars increase, so does the need for computing power, data and power distribution. The car is gradually evolving into a supercomputer with a wealth of features and connectivity. In order to cope with this change, the architecture or foundation of the car needs to be fundamentally adjusted. The traditional approach to automotive architecture may no longer be able to meet current and future needs because it cannot effectively support the growth in content and complexity.

Software, sensing and computing platforms, data and power distribution, and connected services are key elements in a smart vehicle architecture. Developments in these areas are critical to enabling smarter, safer and more efficient vehicles.


Software plays a central role in the architecture of smart cars. Software defines the behavior and functionality of the vehicle and determines the performance and safety of the car. In order to meet the growing functional demands, more efficient and reliable software needs to be developed. This includes using modern software development methods and tools to ensure the quality and reliability of the software.


Sensing and computing platforms are key to enabling autonomous driving and other advanced capabilities. The accuracy and reliability of the sensors are critical to the safety and performance of the vehicle. At the same time, the high-performance computing platform is capable of processing complex algorithms and large amounts of data to support high-level autonomous driving functions.


Data and power distribution are also important aspects of smart car architecture. With the increase in sensors and computing platforms in cars, the amount of data is also growing rapidly. In order to process and manage this data effectively, it is necessary to develop efficient data storage and processing technologies. In order to meet the energy needs of various functions and devices, there is also a need to develop more intelligent power distribution systems.


Connected services enable vehicles to communicate with other cars, infrastructure, and the cloud, enabling smarter transportation systems. Through vehicle networking technology, real-time traffic information sharing, collaborative driving, remote control and other functions can be achieved, thereby improving traffic efficiency and safety.


Therefore, to achieve a higher level of autonomous driving, an integrated vehicle system is needed to control each critical task.
