    Hi, I have recently brought my first full hybrid (FHEV). Being a electromechanical design engineer, I am fascinated how EV work. Watched several of your videos on hybrid systems and this one on regenerative braking explains in detail the electromechanical complexity. Love the diagrams and explanation.

    And where does the “internal leak” occur? This is probably the most important question. "PRV"? or through other valves? How to fix a leak? What was the point of disassembling it, sawing the solenoids for some reason, if it is already clear that there are coils of copper and nothing else. And you can’t get to the place where the main breakdown of this module occurs... But in fairness, this is the only video on TH-cam that I was able to find with such a deep analysis.

    the new integrated braking system from Continental, called MK C1 simplified the hybrid braking sistem by integrating the master cylinder, brake booster and abs module into one single unit that handles boosting, abs, esp, pedal feel, and regen braking.

    • @michaelheimbrand5424
      @michaelheimbrand5424 2 ปีที่แล้ว +1

      That problem is called demolecular diffusion and happens to all accumuators. It´s just like a tire evetually will loose all it´s air if you don´t fill it. Accumulators is a service item. There are things you can do like "arm" the rubber diaphragm in different ways, like Citroën did in the 90´s. But usually this just mean that they stay with the right pressure for longer and instead break completely when that day comes. So "all good", I wouldn´t count on that. Another "interresting" is that normal or catastrophic leakage of accumulator nitrogen pressure ends up as bubbles in the fluid. I guess it can be confusing when you suddenly get "air" in your brakes that seem to come from nowhere.

      @@speedkar99 It´s just me, thinking this could have been built much simpler based on the system from old Citroën´s and their high pressure brake system. And I have heard a lot of people saying stupid things about Citroën´s. :) But I guess this is how they have to do when they want it to feel like "normal" brakes. At least they didn´t fall for the temptation to use vacuum pumps and stuff. BTW, Citroën´s have a rather simple valve connected to the pedal. So the only thing you do with your foot is letting already created pump pressure access the calipers.

      I love old school Citroen brakes! Rock hard pedal, travel is 0.01mm or something like that. Just a pressure sensor, with built in sensitivity to the car load.
      So I’d like to have the artificial feel removed from our Prius brakes :-) Probably impossible, as it measures pedal travel for the regen braking, I presume.
      Yes, we have both a Prius and a Citroen Xm, excellent cars in their own league!

    In this system, if your ABS motor is running very frequently (compared to my other Lexus that use this same system), is it likely an issue of the accumulator holding pressure or would it be the whole assembly unit as that accumulator looks pretty simple. No lights yet, but have had the weird motor squeak now and then as well as the very very frequent running of the motor building pressure which doesn't seem to hold long before it's running again.

      Our 2017 does the same thing. It's really noticeable when braking going over a manhole cover or anything steel. My guess is the stability control is quite sensitive and because the brakes are so automated, the brake actuator releases the brake completely before attempting another application a fraction of a second later. It feels very weird because with conventional brakes this would not occur as the brake force you ask for, you get. The hybrid system probably wants to avoid any sort of wheel locking not just for safety but also because you cannot regen with a locked wheel. Hard to know for sure without getting info from the engineers who designed the system...

    And when this fails in a hybrid Highlander you simply throw this wonderful comfortable car away.
    This particularly painful if the problem has first been diagnosed by a well meaning tech as a dead battery and you put $2,500 into a reconditioned traction battery.
    Then the car shutters while in park, won't charge, throws a bunch of codes and after towing to a dealer a 40 miles away and getting a "certificate of death" cost estimate estimate that you're not sure even solves the problem because it is so comolex, the whole thing becomes a sad experience and an expensive boat anchor.
    Scotty kilmer is right. Do not a used buy hybrid if you want to keep the car a long time. This probably applies to EV s as well.

    I had a code C1391 pop up on my R450. I replaced both the accumulator and actuator to the tune of nearly $2500. But when I watch this video, I wonder if I did the right thing, lol. Then again, so far, everything seems to be working on my RX and no warning lights have popped up. It's been nearly a month.

    hi the e-power note still uses a vacuum brake booster and every time the car thinks that braking might be required it starts the engine because why use expensive electronically boosted brakes when a vacuum booster is cheaper. (no corners were left un-cut) eg no rear speakers

    Just bought a gen2 used prius with 100,000 km with abs issue.. my abs motor is nut running when i open the driver door, though when i open the fuse box, i can hear relays clicking,but when the car is in ready model and starts to move the abs motor run wheh i press the brake while in motion , but during this case most of the braking power come from rear wheels and not front wheels..
    Now, because of this, I am having a few codes related to the abs module. These codes are c1313, c1377, and c1256.. what can i do solve the issue..all fuses are ok, and i can hear abs relays clickiking.

    If they ever get additive manufacturing to be at the same cost/speed as regular manufacturing I could see car mfgs design a manifold without needing to drill oil galleries. You could probably make the part smaller and more compact too without being constrained by traditional manufacturing techniques. Of course if it ever gets clogged you have less access to clean.

    • @speedkar99
      @speedkar99  2 ปีที่แล้ว

      Good thoughts. Additive manufacturing has come a long way, I think it has potential to be mass produced large scale soon

    I tell you what. If you own a Toyota hybrid and want to drive it for decades, you better have sufficient funds!
    They do save you fuel expenses, but when it's time to replace some stuff, Lord help you. 😂
    Back in November, I bought a 2009 Prius with 246k miles on it. I bought it knowing I would have to put some money into it.
    I have replaced almost every major component in this car except the inverter.
    I still enjoy the car, and I better for all the money I've put into it.

    Oh that's so weird, I'm pretty sure my 2011 Kia Optima Hybrid doesn't work that way and instead uses a mostly regular braking system with an electric vacuum pump when in electric mode, I can even hear it running when releasing the brake pedal with its characteristic "brrrrrr" for like half a second

My motor keeps on running as it seems it cant build pressure but there are no brake fluid leaks anywhere. I am thinking that there is an air leak somewhere ..... but where? I have a CT200H
