Last weekend’s rounds of the FIA World Endurance Championship at Spa saw the first full field use of EM Motorsports Micro Accident Data Recorder (uADR). The uADR was developed in coordination with the FIA Institute in support of the FIA ADR Programme and is now compulsory across all classes of the WEC from LMP1 to LMGTE. The use of the uADR is managed jointly by the FIA and ACO and will be expanded further at the next round, the prestigious Le Mans 24Hr where it will be fitted in all cars taking part in the event.
Weighing only 175grams the uADR contains a number of sensors including a 3 axis gyroscope and 3 axis accelerometer as well as having a GPS receiver and a CAN interface to other car systems. This combined with a 16Gbyte memory allows it to capture data before and during an accident for later analysis by the FIA and FIA institute. The uADR also uses supercapacitors to allow it to keep recording data even after a power failure on the car.
The use of the uADR will be expanded to other racing series during 2013/14
