ESVE – Embedded Overspeed Protection
Solutions
Discover ESVE
In 2015 a serious TGV accident occurred near Eckwersheim, in the Grand Est region. This led to the creation of the ESVE system, designed to autonomously monitor the train’s speed in relation to its position on the track during testing. In the event of overspeed, it automatically triggers the emergency braking system to ensure safety.
Using Spherea’s fast prototyping solution, in under six months, SNCF and Spherea developed a reliable solution to help prevent such incidents from happening again. This legacy product was recently re-designed to treat some core component obsolescence and re-use the latest Spherea platform.
