How Hybrid Car Brakes Work

Here’s an in-depth look into the braking system of the Toyota Prius Hybrid.
Hybrid cars cannot use traditional vacuum assisted brake boosters. This is because when the internal combustion engine is shut off, there is no vacuum available to power the brakes. In addition, hybrids use regenerative braking by turning the electric motor in the transmission into a generator to charge the battery. Thus the computer must control the braking pressure applied to the calipers to balance it with the force from regen braking for optimal efficiency and seamless operation to the driver.
A hybrid car’s brakes implores the use of a traditional brake fluid reservoir and master cylinder. The master cylinder takes fluid flow, generated from the brake pedal from the driver and sends it to the stroke simulator. The simulator is cylinder that fills with brake pressure and provides the driver feedback of where the brake pedal is and how much force to apply - although it is still not mechanically linked to the force being applied to the wheels.
The ABS actuator has an electric motor that drives a hydraulic pump that fills an accumulator. This provides the brake pressure to the apply and release solenoids that lead to each brake caliper. The computer can use this setup to completely electronically control the braking system based on the pressure sensed from the driver’s input and the caliper’s output as a closed loop control system. It also interfaces with the hybrid regenerative system through the CANBUS so the braking forces are related to what the driver has requested. The fluid from the master cylinder is cut off completely during this operation, and are left in the fail open position for manual operation of the front brakes in the event of no power.

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 KZfaq that I was able to find with such a deep analysis.

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.

Yes, we have both a Prius and a Citroen Xm, excellent cars in their own league! Thanks for explaining this!

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. Toyota had some issues with that nitrogen accumulator on early priuses but now it seems it's all good

@michaelheimbrand5424 2 жыл бұрын

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.

@kiefershanks4172 2 жыл бұрын

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...

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. It's like when you must put down your favorite dog. You say, "I'll never do that again."

What a piece of junk. Brushed DC motor in a critical system. How, on Earth, will one know if brushes are totally gone? Mind boggles. Thank you for this vid, I'm gonna stay away from Japanese cars! Edit: this dust was probably from brushes.

If the brushes are worn then things might stop working 👀
