Intelligent and Networked Mobile Super Terminals

I. In-Vehicle Networks: The Communication Cornerstone of Vehicle Intelligence

In the era of software-defined vehicles, automobiles have evolved into highly integrated intelligent mobile terminals. Equipped with hundreds of ECUs, vehicles coordinate power, chassis, intelligent driving, cockpit, perception, communication and other systems to form complex in-vehicle networks. High and low-speed data are transmitted concurrently during driving, imposing stringent requirements on the stability and real-time performance of bus communication.

Adopting a layered bus architecture, in-vehicle systems utilize I2C and SPI for underlying ECU communication; CAN, LIN and FlexRay ensure high reliability of control links; CAN-FD and automotive Ethernet support high-speed data transmission for advanced intelligent driving. Siglent delivers full-scenario in-vehicle testing solutions compatible with mainstream bus triggering and decoding functions. Leveraging handheld oscilloscopes, current probes and power analysis tools, it efficiently completes tests on vehicle wiring harnesses, high current and drive modules, covering the whole process of R&D, commissioning and mass production.

II. Anti-Interference Testing: Consolidating the Safety Bottom Line of Automotive Electronics

Modern automobiles are highly integrated with radars, high-speed buses, V2X, smart cockpits and ADAS systems, resulting in an increasingly complex in-vehicle electromagnetic environment and strict standards for EMI and EMS electromagnetic compatibility. Electromagnetic interference may easily cause equipment malfunctions and misjudgments in intelligent driving. Siglent’s intelligent testing solutions can quickly locate interference sources and eliminate potential risks, ensuring the stable and safe operation of automotive electronic systems.
