Brake by Wireless Sensors

[Sheepdip]

Had a discussion with a fellow last night concerning "Wire Braking Systems" that are now being implemented in the automotive world. I knew they worked in similarity to a TPI but that's all I knew. So what happens when it fails?
Just edjumacate myself I looked it up. Still not sold it's fail proof.
(Sorry for the misleading thread title of wireless)

"Still not sold it's fail proof"
Neither are the old systems!
That said here is what happens;
The 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.

Reminds me of a conversation I had with a guy a few years ago. He owned a 2000 something Chrysler family car. He told me it had electric steering. It was the first I had heard of such but he went on to tell me there was NO shaft connecting the steering wheel to the steering linkage underneath. I said BS, there has to be a mechanical connection there for safety. Ha, I didn't convince him otherwise either. Some people right?

So it's good old fashion brakes that make electronic brakes safe. Makes me wonder why electronic is a good idea. Obviously nothing wrong with mechanical/hydraulic brakes since they are so reliable this system relies on them for safety back-up. Ever seen a sensor fail? Not an uncommon thing.

It's tech where tech doesn't need to be, which only drives up original purchase price and repair costs. Crazy, but I guess any revenue is good revenue. I have a '16 Kia econobox that I'm eventually going to replace with something as simple as my '70 truck. I like all the cool features , but once they break...

To address the intent of the OP. It' hard to get an old dog like me to understand "why do we need that".

To address the "Wireless Sensors" angle, I have a wireless brake controller that I run on my motorhome. It works through an app on my phone. The receiver plugs into the 7 ping plug on the MH and the trailer plugs into it.

Then what in the hell is the point. Fly by wire in airplanes was developed to eliminate all the heavy mechanical linkages. Making for a lighter aircraft which has definite advantages. If this system still has all the hydraulics of a conventional system, then what is the point.

Yup!

Hybrids and elect cars have them to control the regenerative braking system.
I believe the are installed so the system can control each brake and do cool stuff like anti roll and anti spin. Not even mentioning the anti skid on a wheel by wheel basis.
As they are mostly on high performance cars like the C8 Corvette.
