Renault has set up a high-tech facility in France to study electromagnetism in cars
|
It looks like the villain's den straight out of a James Bond movie, but this is Renault's new EMC (Electromagnetics Compatibility) unit, which opened recently in Aubevoye, France. Renault's new EMC Unit, a new testing facility, was designed and built at a whopping £7 million.
The new unit is dedicated to the study of electromagnetic compatibility in vehicles and contains all of the facilities required for the testing of electronic equipment in vehicles. Occupying an area of 1,800 m2, the new unit is equipped with the latest technologies in the EMC field. The building has three Faraday chambers grouped around a remote control room, with each room designed to be impervious to electromagnetic interference from external sources.
The unit has commenced testing future Renault models beginning with the successor to the Laguna. The tests will start with the first prototypes and will continue throughout the development of the vehicles and this will soon stretch to Renault and Nissan models within the framework of the Renault-Nissan alliance as well.
What do they test for?
Electromagnetic immunity (EMI) - this describes the vehicle's ability to resist electromagnetic interference from external sources. Aspects such as the filtering of the electronic module inputs, the design of the printed circuits, and the screening and arrangement of the vehicle wiring will be monitored and validated by the EMC unit. This area also deals with mutual compatibility of on-board items of equipment, or their capacity to operate in tandem without interference.
Electromagnetic quietness (EMQ) - this describes the capacity of a vehicle to operate without causing interference to the surrounding environment. Radio frequencies - purpose is to optimise the reception and transmission of RF data used by on-board radio, satellite navigation and digital television systems.
