The technical failure in Bianchi's accident

7. During the 2 seconds Bianchi’s car was leaving the track and traversing the run-off area, he applied both throttle and brake together, using both feet. The FailSafe algorithm is designed to over-ride the throttle and cut the engine, but was inhibited by the Torque Coordinator, which controls the rear Brake-by-Wire system. Bianchi’s Marussia has a unique design of BBW, which proved to be incompatible with the FailSafe settings.

8. The fact that the FailSafe did not disqualify the engine torque requested by the driver may have affected the impact velocity; it has not been possible to reliably quantify this. However, it may be that Bianchi was distracted by what was happening and the fact that his front wheels had locked, and been unable to steer the car such that it missed the crane.

Would seem to have been a direct repeat of what happened to Maria De Villota


She sustained her injuries after her car "suddenly accelerated" into the back of the support lorry, according to witnesses.

Marussia says it carried out a detailed analysis of the accident, and an external forensic investigation was also conducted. The results have been passed on to the Health and Safety Executive.

"BBC Cambridgeshire presenter Chris Mann, who witnessed the crash, said the car was slowing down when it "suddenly accelerated" into the back of the lorry"
