Brake-by-Wire and concerns

I'm interested in this thread....

 

This is a good explanation, which applies to basically all brake-by-wire systems. Ferrari's included.


As with all systems, including the one in the SF90, brake-by-wire systems maintain a physical connection between the pedal and the brakes themselves. If something goes wrong, a valve opens up that bypasses all the electronics, leaving you with a conventional hydraulic system. (This is one reason why the SF-90 still requires brake fluid)

 

The Tesla Cybertruck is the first brake-by-wire system with no mechanical backup … should be interesting. Lots of steer-by-wire systems and you don’t hear stories of system failures … probably illogical but having no mechanical backup for brakes is a bit frightening

The only steer by wire systems without a mechanical connection is that of the Cybetruck and the yet to be released system of Toyota/Lexus. Toyota deals with the issue with a triple redundancy system.

 

As does the Cybertruck.

And all airplanes (since the 1990s) are steer-by-wire.

 

All airplanes since 1990’s are NOT steer by wire. In fact very few actually are. Almost The entire platform of citation jets are old school cables. This is a very false statement.

Hahahaha i think i have some comments on this topic.

There is no way to loose all of braking power on this car trust me I tried it!

So my last track event i went out with moderate wear on my brake pads but i know SF just devours brake pads so i was on the edge. While i was on the track brake warning come up and said brake pads are worn see the dealer BUT! In my native language worn and overheat are written in very similar i mean there are several ways to describe it (ISINDI & ASINDI) as a stupid like me you can mixed them. I hear you are asking does it matter just pull the car right NO! I kept going because i had rear brake over heating alert on SF many many times before even not pushing it and dealer never figured it out and i was like this is the nature of this car and i thought why rear brakes overheating not the front so i thought it’s just a Fcar glitch i should live with it and i moved on!

So i lost my brakes at 260 Km/h. UFFF but you know what SF has a really goooooood Regenerative braking in like milliseconds regen braking started gripping and i was good no problem S*** my pant but it’s better than kissing the wall

You will ask how you didn’t felt anything weird. I did but i was goofing around drifting and doing taxi laps on the track, thanks to regen you cant feel like you are loosing you brakes because on Qualifying it’s just regen it to keep the battery at top.

I post couple pictures of my pads and you will understand how strong the regen braking on SF90.

Usually, cars got your back with backup systems and fail-safes to keep you safe, just in case the electronic brake module decides to chill for a bit. They've got redundancy systems, backup power sources, and fancy sensor setups to make sure that even if the electronic brakes throw a tantrum, there are other tricks up their sleeve to stop the car safely. But, you know, the nitty-gritty details can differ between brands and models, so it's a good idea to dig into the techy stuff in the carmaker's documentation.

 

Airbags?
