As a car that can run scientifically, the car is definitely not as simple as “four wheels plus two sofas.”

If the platform is the skeleton of a car, then a complete electronic architecture is the “brain and nervous system” of the car, which includes wires, sensors and control modules.

The human nerves extend in all directions, as do the car’s electronic architecture. It connects, drives and controls all the functions of the vehicle, ensuring that all subsystems of the car work together in an orderly and harmonious manner.

In the 1990s, GM began to develop the electronic architecture of automobiles. With the rapid development of technology, in order to quickly realize the electrification and intelligence of vehicles, communication and subsystem cooperation of automobiles are facing no small challenges.

The advancement of the car is inseparable from the development of the basic electronic architecture.

To meet the needs of next-generation vehicles, GM has released a new generation of electronic architecture. It can process 4.5TB of data per hour. Compared with the previous generation, the data processing capacity has increased five times.

Strong data throughput with high-speed networks enables faster in-vehicle communication, vehicle and external communications, and accelerates the advancement of advanced technologies such as autonomous driving, active safety, and smart connectivity.

Based on the new electronic architecture, GM vehicles will be fully OTA-capable, and most software-controlled subsystems on the vehicle can be tuned and upgraded through OTA throughout the vehicle’s life cycle.Levels, including engine and transmission control modules, in-vehicle communication systems, in-car entertainment systems, and body control systems.

This electronic architecture not only adapts to future electric vehicles, but also covers fuel vehicles such as cars and trucks, enabling cross-brand and cross-platform.

It is understood that the current general electronic architecture R&D team consists of more than 300 electrical, hardware and software engineers and computer scientists, and has produced more than 100 patents in the development process.

About cybersecurity, the official claims that the electronic architecture is benchmarked at the aviation level.

In order to achieve the highest quality and reliability, engineers conducted three different levels of verification testing of the electronic architecture. Even the parts verification that the supplier is responsible for must be strictly implemented in accordance with GM’s standards.

In the early model phase, they performed vehicle environmental verification of the entire electronic architecture to ensure it worked in the vehicle environment. The bench verification runs through the entire development process.

In order to ensure that the architecture can adapt to China’s complex network environment, the labs at GM China’s Forward Technology Center and Pan Asia Technology Center are also involved in the verification and testing of this new system,

In terms of product planning, the architecture is currently on the Cadillac CT5, and the new car will be available in the North American and Chinese markets in the fourth quarter of this year. By 2025, more than half of GM’s global brand models launched in China will be equipped with this new electronic architecture.
