Bianchi crash FIA report

2014 Gruodžio 03 d. 19:12

Jei dar neskaitet, ten nemazai idomiu dalyku, anksciau neskelbtu.

Pvz.:
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 incompati*** 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 possi*** 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 una*** to steer the car such that it missed the crane.

cia nuo siu metu failsafe su hybridais atsirado? nes kiek atsimenu pilotai visada dirba abiem kojom ir kai kuriuose posukiuose neatleisdami akseleratoriaus spaudzia stabdi apkraudami prieki.

Cia kalbama apie abieju paminu iki galo isminima.

AF1>> tai nuo kokiu metu tas Failsafe? Nes Massa gaves is spyruokles i galva abu pedalus iki dugno nuspaudes laike ir variklis neuzgeso

slimmaz>>>as tiksliai nezinau to bet manau butu visai logiska jei sekanciais metais po to kai masa gavo is spyruokles kakton ir atsirades butu toks mechanizmas, nes taip sakant daugkas atsiranda jau post factum

Massa gaves is spyruokles prarado samone ir kojos atsipalaidavo t.y. abi paminos pasispaude kazkiek nuo naturalaus pedu spaudimo. Bet jokiu budu ne iki dugno.

Nuo kada sistema - nezinau, bet manau guglas zino.

tai kad telemetrija rodo, kad iki dugno https://www.youtube.com/watch?v=IzKc76-isOk

Jei pažiūrėtum daugiau tokių video, tai pastebėtum, kad stabdžių pedalą visada rodo nuspaustą pilnai arba nenuspaustą išvis. Tarpinių padečių ten nėra. Su akseleratorium viskas gerai, įdomu kodėl jie čia taip padarė.
Kitas reikalas, stabdžio pilnai neišminsi būdamas nesąmoningas, ne vaikiškai spausti reikia :)

Might be cutoff sistemos tuomet nebuvo.

is sio straipsnio an panasu kad turbut tik siemet ir atsirado tas mechanizmas

ir citata tiem kas nenori viso straipsnio skaityt:

During the 2 seconds Bianchi’s car was leaving the track and traversing the run-off area there was still time to avoid the recovery vehicle, and Bianchi attempted to do so. He applied the brake, but this locked the front wheels making it impossi*** to steer, also for some reason he also applied the throttle (it is not clear if the throttle was already applied from the reports findings, but it probably was and Bianchi simply did not lift).

In this scenario the engine should have cut as all 2014 F1 cars have a back up safety system called FailSafe. It is a software algorithm in the cars onboard computer that is designed to override the throttle and cut the engine in exactly this scenario, but on the bespoke Marussia brake by wire (BBW) rear brake design another sub system the Torque Coordinator which controls the the operation of the BBW prevented it from doing so. It transpired that the Marussia MR03 BBW system was incompati*** with the FailSafe settings used by all cars.
