Automotive – a fast developing moving network system
There are more than 100 electronic control units (ECUs) in a car, which control the engine, air conditioning, steering, camera, brakes, wireless communication and other systems to form an in-vehicle network system. When a car is working, a large amount of information needs to be exchanged between different nodes, and there are both high-speed signals and low-speed signals. In order to improve communication quality and save costs, a large number of bus communication protocols are used in automobiles. I2C and SPI are heavily used in ECUs. Controller Area Network (CAN) and Local Interconnect Network (LIN) are used in applications where reliability is greater than speed requirements. During the design of automotive, engineers need reliable test tools, and SIGLENT can provide you with:
· Triggering and decoding of I2C, SPI, CAN, LIN, CAN-FD, FlexRay protocals;
· Use the handheld oscilloscope for automotive wiring test, portable and easy to operate;
· Cooperate with current probe to measure large current safely;
· Power analysis software
Eliminate interference
From the electronic fuel injection system that emerged in the last century to today's abundant in-car entertainment and the future Level 5 Advanced Driver Assistance System (ADAS), automotive electronics are growing rapidly. This also raises higher demands on the security of electronic and communication systems.
 
As cars integrate more and more RF standards, radars, and high-speed data buses, automotive electronic components must meet automotive manufacturers' EMI and EMS specifications. The solutions provided by SIGLENT can quickly locate source of interference, eliminate potential safety hazards and prevent dangerous operations such as mis-ignition.
