Your videos are the best. Every time someone asks me how something works in a car, I check if you have a video on it. I know I'd never explain better. Thank you so much for making these!
Well it's fine todo that. What I don't see is why we need Steering By Wire as that is adding more parts that break than less, the only real benefit I can see there is less positioning restrictions but currently that isn't done at all.
Packaging & safety are potential benefits of steer by wire. Steering shafts have evolved over time to include crumple sections & slip joints, but I could see how no shaft would be safest for the driver.
The biggest benefit with steer by wire is that you can vary the steering ratio: make it fast around town and parking lots so you don't have to turn the wheel so much but slow on the highway so it's not twitchy. Still, it seems to me to be an answer to a question no one is asking.
I totally appreciate the engineering in the system and the concept that it's perpetuating our aging driver's education procedures. I'd just as soon use regular non-vacuum assisted Hydro-Mechanical brakes, and then have the regeneration on a split brake pedal. So, when you press the far left edge of the pedal, you're on regeneration, but if you exceed the threshold of the primary pedal travel, it simply actuates the hydraulic system as intended. Andrew Tate is right about driving.
The problem is that the point at which that threshold happens needs to vary according to the amount of regen the battery can handle. The transition from regen to hydraulic needs to be seamless and this presents a very difficult mechanical problem. De-coupled systems are designed to solve that problem.
@@suspensionsexplained What amazes me about EV's is having the motor hard-splined to the rest of the geartrain. Irregularities in the road go straight into the drive assembly, and we end up with monster rubber bushings.
the brake by wire system is fine, until it breaks........ and those that are repaired by unqualified mechanics......i worked at a car dealership in an area that is near a collection of 30+ wrecking yards, and have seen first hand the janky crap people cobble together and resell to unsuspecting drivers.... also: then there's the DIY crowd, that won't pay a trained and qualified repair technician to replace whatever malfunctions on their vehicle, they'll find a RUclips video on how to fix it from some other unqualified hack.... as a retired 25+ year Master Automotive Technician I've come away with a few things: 1) there are repairs on some vehicles that some folks just shouldn't do. 2)there is always some unforeseen problem in a system after it was designed- which is why we have safety recalls..... what prompts those recalls? usually it's because someone died.... let that sink in......
Unfortunately, this is the way every other system on cars has been going for many years now. There's very little you can do yourself any more. I grew up on points and distributors and I like the simplicity of the old days. But I also like a car that starts no matter the weather and won't kill me if something goes wrong.
I've seen control modules on modern cars spontaneously reboot while going down the road. Brake-by-wire is a *terrible* idea. When drive by wire fails-safe, you coast to a stop and keep your steering authority. When brake by wire fails-safe, you're going to abruptly stop in the middle of the highway, which is nearly as unsafe as having no brakes at all.

You're very welcome!
Best automotive channel on RUclips, dont stop making these.
Legitimately
Very interesting!

Thank you for clear explanation sir.
Not fluent in english, but i still able to understood what are you saying.
Your English seems fine to me!

Link check.

How? 9:47 explains the fail-safe valves.
The failsafe is you have a push-through system, just like the days of old. The system won't just abruptly stop by itself.
I’ll give it a watch before I disagree lol in case you can convince me
I guess I am convinced lol 😊
