During actual vehicle operation, motors, electronic controls, on-board electronic devices and other components create a complex electromagnetic environment, which is highly likely to cause electromagnetic interference to the steering system. Insufficient immunity of the steering system may result in steering jitter, loss of power assistance, or even loss of control, leading to fatal accidents especially under autonomous driving scenarios.
Conducting electromagnetic compatibility (EMC) immunity tests on the steering system verifies its stability in strong electromagnetic environments in advance, accurately identifies weak points in anti-interference performance, and eliminates potential safety hazards caused by electromagnetic interference at the source. This provides critical support for the safe operation of electrified and intelligent vehicles and the reliable implementation of autonomous driving functions.

Q 1: Will the EMC steering robot generate electromagnetic interference and affect vehicle EMC test results?
A1: No. Specially customized for anechoic chamber EMC environments, the robot adopts a fully shielded, low-radiation and non-magnetic design. All core components are shielded to eliminate stray electromagnetic radiation during operation. It maintains ultra-low background noise without interfering with vehicle RE and CE test accuracy, fully complying with strict CISPR 25 Class 5 standards for accredited tests.
Q 2: Is this robot compatible with steer-by-wire vehicles and solve manual dynamic test difficulties?
A2: Yes, it perfectly adapts to steer-by-wire models. Manual operation cannot maintain fixed steering angles for non-power steer-by-wire vehicles, leading to invalid dynamic tests. This robot stably simulates full dynamic conditions such as fixed cornering, sine swing and lane keeping. It is compatible with fuel vehicles, new energy vehicles and intelligent drive-by-wire models, solving the dynamic EMC test pain points of new-generation vehicles.
Q 3: What are the core advantages of using a steering robot for dynamic EMC tests compared with manual operation?
A3: It realizes standardized, traceable and unmanned high-efficiency testing. Manual operation suffers from angle deviation, unstable working conditions, human fatigue and extra human electromagnetic interference, resulting in poor data repeatability and invalid certification results. The robot provides high-precision and highly consistent steering control, supports long-term unattended cyclic tests, greatly improves laboratory efficiency and fully meets global dynamic EMC compliance specifications.
