It's no worries if you lose power with electronic breaks! As Audi describes, if you lose power, a check valve means your electronically controlled breaks are now regular old hydraulic brakes, and your foot does all the work again. Phew! 😅 And, electronic brakes have the added benefit of being able to stop with the brake fluid boiling, as they can pressurize the "air" enough to stop the car, versus a brake pedal which just hits the floor, and then you're done. Neat!1!1

@jac1207 2 года назад

I think I remember an F-22 test pilot giving a lecture and mentioning the new fighter jets had the control stick not move at all, it would sense the pressure the pilot exerted on it, and how it was really weird for the human pilots and they had to design sticks that moved.

@Captain_Irk 6 месяцев назад

I may be incorrect, but I think this was something first tried in the F-16, and since humans are better at knowing the position of our limbs than how much pressure we're exerting with them, they found it was more intuitive to build some movement back in to avoid feedback loops of pilots overcorrecting errors. I wonder if the f-22 control stick was identical! My source is "The insane engineering of the F-16" by Real Engineering, around 22:30.

@genius1a 2 года назад

I like the title and the explanation of the basics. There's even more to it: In May 2004, Mercedes recalled 680,000 vehicles to fix their complex brake-by-wire system. Then, in March 2005, 1.3 million cars were recalled, partly because of further unspecified problems with the Sensotronic Brake Control system. If the electrical break failed, they had a classical foot driven hydraulik backup, but only to the front wheels and without the typical vacuum servo assistance. That happening without pre warning resulted in way longer brake distances, subsequently leading to some accidants of almost brand new, well maintained upper class cars. In 2006 they discontinued the system in the E- and S-class limousines. Secondly: There were cars, that had no direct hydraulic connection from the break pedal Movement and no feedback at all: The Citroen DS and CX upper class cars had just a foot controlled, spring loaded hydraulic valve for breaking. A single belt driven pump provided hydraulic pressure for the breaks, the clutch, hydropneumatic suspension including the dampeners and for the power steering, that also had no mechanical connection to the steering gear (but a mechanical fallback with extremely wide dead clearance) . Buyers loved the lack of feedback, testers hated it. They sold 2.5 Million from 1955 to 1991, not so bad for upper class cars of legendary complexity and maintanance costs. If the pump failed, there were several storage tanks, that provided full usability for some more minutes. For example after 20 times of breaking, it stopped working and you were left alone with the mechanical handbreak with litereally coin sized brake pads (on the Citroen CX). The system worked surprisingly well, the safety record was flawless.

@roland9367 2 года назад

Regenerative braking can actually be done so well, that you hardly use the regular brakes at all. In fact, if you press the brake, it will also regen brake first. One pedal driving is a common thing in EVs. You are just using the actual brake calipers when you have to brake more in unexpected situations, or you just driving faster, requiring more brake power to stop for the red light.

@drazenradosevic7467 2 года назад

Agree to that. Regen braking (especially if you have front motor) can cover 99% of traffic situations. New trend for electric commuter cars is to reduce max speed anyway, so all that means that brake overheating will not be an issue. Ventilated disk will not be necessary, brake calipers and pads can be also made smaller and lighter. Additional bonus is the reduced unsprung weight... Of course, with performance cars, it is another cup of coffee :-)

@taurus600 2 года назад

Same concept as driving an ATV or side by side with a CVT transmission, one pedal driving. Those cvts have very snappy engine braking ability

@xeridea Год назад

@@drazenradosevic7467 Normal size pads still needed for emergency situations, but you basically never need to change them since they are rarely used under normal driving. The Model S Plaid under full breaking from top speed to zero, even with regenerative braking to assist, the calipers get very hot. This is a bit of an extreme situation, but there is a need.

@evilbred974 Год назад

This is the answer of when electric brakes will be common on cars. It will only happen after the majority of drivers are driving EVs with regenerative braking. Once people get used it, and get comfortable with regen braking, they'll be more receptive to fully electric system.

@MoGreazy 2 года назад

Indeed… I had an SM, which had the same system. These cars had a high-pressure hydraulic pump that actually supplied the pressure. Your foot on the “mushroom” simply opened a valve. Yes, we got used to it, but these were by no means sports cars… It is the equivalent of a steering system that gives very little road feel. There was an accumulator in the system, so that you still had a pressure reserve in the event of the engine quitting on you… which the Maserati V6 had a anasty habit of doing, in very bad ways…

I worked in electrical technology in my high-school a year ago and what I've learned is the more simple and tough you can make something the more reliable it will be

@ProtoV33MK1 Год назад

The Nissan Leaf does this in an admirably simple way: the master cylinder is just set back about an inch and a half from the pedal arm, so the first 2 inches or so of pedal travel are just an input to the computer asking for regen braking, but if you push further, you hit the master cylinder and apply the friction brakes. so even with no power (12V and traction battery disconnected) you still have conventional braking to stop the car. The power steering works the same way, just with an electric pump instead of a belt driven one.

Brakes will always need a backup system. As in power brakes and power steering. Parts critical for the safety just need a working manual override. BTW, about no power situation: it's actually solvable. Think of the brakes that are "normally closed" and you need to actually provide power to lose them. The hard part is to make it energy efficient and fast at the same time.

Also another nice thing with manuals, you can downshift to PREEETTY high RPM's over what you usually use on a normal car and then use the handbrake to catch the last bit of braking.

there are some advantages actually. better automatic braking is one of those, but one thing that i wished they had mentioned was advantages in the event of brake fluid boiling. your brake pedal can only travel so far but an electronic pump can just keep pumping fluid until it moves enough fluid to stop the car. i watched one video on the c8 corvette where they talked about that. obviously, you can’t just keep driving with the fluid overheating, but it’s enough to stop the car in the event of such an emergency.

I had my brake line burst on my Silverado coming up to a red light @ 50MPH. F'n terrifying. Was able to jump on the shoulder and pump what was left of the brakes before hitting intersection. So hydraulic isn't perfect either. For electronic brakes, you would absolutely need some form of fail-safe system like railway air brakes. So that if all power is cut, the brakes are applied. An example could be a spring powered clamping brake pad that's held open when there's power but clamps disk if power is lost. Would really suck having car suddenly stop by itself but way better that suddenly zero brakes, I can attest to that personally.

A lot of cars already use electric assist for the brakes. The Prius has used that since it was released in the US in like 2000. It’s backup in case the vehicles 12V system fails is a large bank of capacitors in the HCU that gives you enough electricity for about 5-10 stops without the 12v system, so similar to a vacuum assisted brake system. After that, you can still use the brakes, but they’ll be unassisted, so it takes a lot more force (again, the same as stopping in a car with vacuum assisted brakes if the vacuum supply is interrupted, or hydro boost for that matter) Tesla uses a fully hydraulic brake system with an electric assist. As far as EVs go, the Tesla brake system is really basic because they don’t do any sort of blended braking (I.e regenerative braking that is requested by the brake pedal). When you step on the brake pedal in a Tesla, you aren’t adding any regen braking, your only adding friction braking. This is very different than any other EV, for better or for worse. I’m not sure there is a compelling enough reason to replace hydraulic brakes entirely with electric yet. The reasons you gave don’t work for me. ADAS systems can apply the brakes either by using a servo on the brake pedal (this is what Tesla uses, you can actually watch the brake pedal move when it activates, some others use it as well) or for emergency braking systems, the ABS system is used to apply strong pressure to the brakes (that’s why ABS systems have pumps, even back before ADAS was a thing). As far as different brake modes, eh no. That’s not needed. The only reason I can think of to replace the hydraulic system would be to eliminate hydraulic failures (especially from rust) but electronic systems have failures as well, including rust failures. An electric system may not need fluid services, but the maintenance would move somewhere else, like cleaning/lubing the brake servos.

Fiat used a similar concept in the electric 500e. It had an electrically boosted brake that engaged under 7mph or in an instance of hard braking. Above 7mph pressing the brake pedal actually varies the level regeneration of the electric motor, press hard on the brakes and the brake pads would be engaged. The system worked well as an alternative to one pedal driving by most electric cars. There was a slight jerk as the normal brakes came on at 7mph, but after a few days you get used to it and compensate.
