Reverberation Chamber (RVC)
Establishment of a Reverb Chamber (RVC) to expand the Automotive Technology Center.
As many automotive parts are now electronically controlled, the automotive industry has begun to emphasize the implementation of EMC tests that simulate actual usage environments from the perspective of quality assurance. The UN ECE Regulation has introduced the RVC method, which is closer to real-world conditions compared to the traditional ALSE method (Antenna Coupling Method). To quickly respond to changes in standards, UL Solutions is expanding its Automotive Technology Center and introducing a Reverberation Chamber (RVC). A Reverberation Chamber (RVC) is a shielded room that contains a metal stirrer (mixer). It is primarily composed of equipment that allows for changes in resonant frequencies due to the rotation of the shielded cavity and the electromagnetic wave stirrer. By rotating the electromagnetic wave stirrer in steps, various resonant modes can occur at certain frequencies, enabling the generation of a statistically uniform field within the chamber.

Applications/Examples of results
By using RVC, a uniform electric field can be generated within an anechoic chamber, allowing for tests that simulate the electromagnetic environment of urban areas where vehicles are actually used. This enables reliable EMC testing that meets the rapid electronic control advancements in vehicles in recent years.

Automotive Technology Center Expansion! Online Tour Information
We will hold an online tour to introduce the Reverberation Chamber (RVC), which will start operations in October 2022. Even for customers who find it difficult to visit the site in person, you can view the expanded Automotive Technology Center online. In addition to the RVC, we will also introduce the EHV Chamber, which is a fixed-dynamo equipped anechoic chamber. In the automotive industry, there is a demand for quick responses to changes in the environment and regulations surrounding vehicles. The UN ECE Regulation has introduced the RVC method, which is closer to real-world conditions compared to the traditional ALSE method (Antenna Radiation Method). The RVC can generate a uniform electric field in the anechoic chamber, allowing for tests that simulate the electromagnetic environment of urban areas where vehicles are actually used. We hope you take this opportunity to view our new facility.

Automotive Technology Center Expansion! Invitation to the RVC Open House (Viewing Event)
As many automotive parts are now electronically controlled, the automotive industry has begun to emphasize the implementation of EMC tests that simulate actual usage environments from the perspective of quality assurance. In accordance with UN ECE Regulation, the RVC method, which is closer to real-world conditions compared to the traditional ALSE method (Antenna Coupling Method), has been introduced. To quickly respond to changes in standards, UL Solutions has expanded its Automotive Technology Center and introduced a Reverberation Chamber (RVC), which will be operational starting in October. To commemorate the operation of the RVC, we will hold an open house, and we encourage you to apply for this opportunity. For details about the open house and how to apply, please check "Details & Application."
