Compared with the traditional test method based on real load controller and wireless communication network, TBOX test method does not depend on the overall development progress of vehicles and vehicle networking system, and the test intervention time is earlier; At the same time, the wireless communication environment with virtual simulation can effectively cover the failure mode test scenarios such as forward direction and communication abnormality; Finally, replacing manual verification with automation not only improves efficiency, but also ensures high accuracy and reliability.

Acceleration sensor is widely used in automobile test, which plays a key role in airbag system, vehicle stability control system, suspension system, braking system and other fields. By testing the acceleration sensors, engineers can ensure the performance and reliability of these sensors under different conditions, thus providing accurate data support for the automotive electronic control system. When testing acceleration sensor, both laboratory test and real vehicle test are very important. Laboratory testing can provide a controllable testing environment, while real vehicle testing can simulate real driving conditions.

In each domain, the domain controller is equivalent to a high-performance ECU, which is responsible for the function control and forwarding within the domain, which requires the controller itself to have strong processing power, ultra-high real-time performance and a large number of communication peripherals. CAN and FlexRay communication buses, which are commonly used nowadays, can still be used for system interconnection within each domain. For communication between different domains, Ethernet with higher transmission performance is needed as the backbone network to undertake the task of information exchange. The development of domain controller, on the one hand, is due to the development needs of vehicle electronics, which can greatly optimize the vehicle electronic and electrical circuits.
