The new unit houses the facilities required for the validation of electronic equipment in vehicles.


Given the development of on-board equipment of this type, the unit has three goals: to ensure the immunity of vehicles to electromagnetic interference from external sources, to control electromagnetic emissions from vehicles and, finally, to measure the radiation performance of radio aerials.


The unit will commence work in May 2006 on applications for the successor to the Laguna.


Renault has been involved in EMC and radio frequency research for over 20 years.

The unit will enable the lead times involved in testing and validating vehicles to be reduced.


Occupying an area of 1,800 m2, the EMC unit has three Faraday cages grouped around a remote control room. These are designed to be impervious to electromagnetic interference from external sources.


Unique of its type, the radio frequency test chamber is dedicated to testing the radiation performance of radio aerials. Incorporating a 12-metre diameter arch comprised of 132 high-frequency and low-frequency sensors, the chamber enables 3D radiation diagrams to be produced in two hours compared with about two days for 2D patterns. In the immunity test chamber, the electromagnetic resistance of the vehicle is tested under extreme conditions.


The EMC unit has links with the electrical engineering and electronic systems department (DIESE) at the Renault Technocentre in Guyancourt, France, where there are also two test chambers.
