Shimano Files Patent for Anti-Lock Brake System for Bikes

Oct 23, 2019
by Daniel Sapp  

Shimano has filed a patent for an ABS (Anti-Lock Braking System) for a vehicle that uses human force as the means for motion, which was first spotted by Bike Radar. This indicates that they are well on their way in the development of a working ABS system. ABS systems have been around for a long time in motor-driven applications including motorcycles, the first being patented in the late 1920s.

An ABS system is automated and uses sensors to quickly manage braking forces applied to the braking system of a vehicle to prevent it locking up and sliding, which causes a loss of traction. It is designed to help improve control of a vehicle and to decrease stopping distances on various surfaces. Over the years, systems have become increasingly complex and advanced. In a perfectly working system, the user could apply the brakes of whatever vehicle as hard as they want without fear of losing traction. Systems for motorcycles also have sensors to evaluate tilt and whether the wheels are on or off the ground.

Earlier this year, we reported on Tom Stanton's ABS system. Bosch also have a system for commuter and e-bikes, Volkswagen and Audi filed a patent for a two-wheeled bicycle system over a decade ago, but this is the first we've seen from Shimano.

While we can see the primary application of Shimano's system being pedelec bicycles, their patent doesn't limit it to that. The system specifically leaves things open to human-powered mountain bikes, cross bikes, and road bikes as well as different style drive systems including belt or shaft drive applications. The system is more complex than the VW/Audi one, with more sensors.

E-bikes are the likely candidate for Shimano's ABS system, but the patent leaves the door open for other applications.

According to the patent, it seems that the system could have a LIDAR style optics system that detects wheel movement in relation to the ground and GPS in it. Interestingly, Shimano also recently filed a patent for a brake rotor that has a magnetism generation device that can "detect the rotational state of a bicycle wheel". This is yet another piece of sensory equipment that could help in executing the system. How it all works together and what will it look like in the end is yet to be seen and, of course, it's just a patent. There may never be a product at all.

While the patent leaves things open to mountain bikes, it's hard to imagine the system being practical or desired by most trail riders. Where would it benefit someone the most? We suspect that pedelec eBikes will be a big market, and we can't forget bike share bikes where increasing safety is a concern. Mountain bikes and cross bikes? It's doubtful.

 @nialo: The Guide R's really do suck, and Sram should be ashamed of them. They are giving all guide brakes an undeserved bad reputation.

Everything above the R brake is good. Comparing them to Shimano, Guide R vs SLX - choose SLX. RS vs XT - it comes down to if you prefer an on/off feel, or a more progressive feel to your brakes.

 @endlessblockades: You got lucky! I had two warrantied brakes and they didn't pay for install for my internal routing, and on the third warranty issue SRAM denied me. I also have RSC.

Guide RSCE is the dream over here, I just haven't felt like I needed anymore brake than the RE in stock form.

 @jncrider: I have a one set of Guide brakes with Trucker Co yellow which I believe are semi-metallic, but I also have a set of Galfers on Guides which I believe are organic. Sorry - I'm not that geeked out on my setup to know for sure. I got Galfer pads because I got some Galfer floating rotors for another bike (which has TRP brakes) and they were on super-sale. A friend uses Kool Stop and I rarely hear them honk - sometimes when it's real wet and your haven't hit the brakes for a while, they will squeak. It's a crap shoot but it's def possible to run Guides without attracting geese.

 Rented a trek remedy with guide R's at the bike park this summer and on top of the remedy just being a shit bike overall the guides would just stop working at the end of the runs. It was as if the brakes were just taken off the bike completely.

 @spankthewan: The Shimano circlejerk is real here. Even reviews of Shimano brakes all say they modulate poorly. It's been known for years that servowave has great power at the lack of fine finesse.

I mean, we have an article on Shimano making a system that for all intents and purposes makes no sense on a modern mtb, but the top comment is purely shitting on Sram. Shimano can do and say no wrong to this community.
  • 7 7
 @chriskneeland: until last month, I didn't understand why people were complaining about modulation of Shimano brakes. Mine were awesome.
But, now I have a second hand bike that came with the same SLX I liked before but with a shitty fork (and an awesome 69° head angle).
And now I understand. It's really hard to brake with the front brake without losing traction or having the fork diving right into the bumpers. So it feels like the brakes are "too powerful". Actually it's the fork (and headangle) that doesn't want to brake, and ABS won't help here.

 Right, wouldn't need it if they had the modulation my Trp's have.

  • 13 8
 @spankthewan: Yea- I have 3 pairs- not one has the wandering bite point.

But since you brought it up, when it gets really hot out and your Srams lock up, would you call that better or worse modulation than Shimano Wink

 @nfontanella: Absolutely
  • 5 8
 @sherbet: You seem to have a reading comprehension issue. The article is about ABS brakes for bikes, not specifically mountain bikes- even touched on it in the article.

Secondly, putting out that I and other people have no issue modulating Shimano is not shitty on other brakes( funny how you assumed Sram).
  • 16 4
 @mnorris122: I have a better solution, third party brake systems that give me both power and modulation. You don't need to run Shimano/Sram, there's tons of great alternatives on the market, and yes, it's okay to be honest about how Shimano isn't a perfect system.

Perfectly happy on Hope brakes, thank you. I have had many Shimano brakes in the past, and all served well. None were good enough to want to keep.

 @sherbet: Well said.

 @TheOriginalTwoTone: I think you misunderstand. I'm saying this system has very little benefit to the people reading the article, given you also ready it and it's specifically not for mountain bikes, you're agreeing with me on the fact that it wouldn't be a good system for an MTB. Are you sure I'm misreading this?

I didn't assume Sram. The top comment is about Guide Rs. Last I checked that was a Sram product. Did you perhaps misread me?

 Bahaha Shimano circlejerk is getting messy in here...the whole fn reason Shimano is investing in this ABS bs is because they know their brakes bite too much. When you only need 15% braking power, Shimano gives you 90% instead. Shimano = slower. You can have powerful brakes with modulation...plenty of options out there.
  • 5 3
 @spankthewan: Glad to hear that I'm not the only person to find Shimano brakes to be inconsistent.
  • 4 2
 @TheOriginalTwoTone: My Sram brakes have never locked up, but they are a pain in the ass to bleed and not as powerful, so I run Shimano and put up with the wandering bite point when I'm really pushing the brakes to their limits.
I do not experience anything negative with Shimano brakes while merely putzing around, but braking last second into a high-speed, high-risk corner, only to have the front pads lock onto the rotor within the first 5mm of lever pull is pretty unnerving. This has been documented countless times. Seems you've lucked out.

 @mxjeremy @sherbet @chriskneeland @spankthewan

It's OK to dislike Shimano brake's initial bite but it's also pretty easy for most people to get used to. I personally like it.

The only reason it's a problem is when the wandering bite point shows up. That combination really does make it a problem.

 My Shimano XTs had really good modulation for the first month, then by mistake I must have activated the autonomic modulation system, and don't know how to turn it off. They go anywhere from Formula The One with 250 rotors to Sram Guide R with 140 rotors and contaminated pads. Can anyone help?

 First off-- I LOVE all the nerding out I'm seeing in this article.

Second-- did anyone else find the M810 generation of Saint brakes infinitely superior to anything else shimano has put out since?

I got newer saints and absolutely hated them. The old gen was definitely a powerful grabby brake, but it still had a solid feel to it and felt controlled.

 Actually anything without service wave has really good modulation.

I stripped the threads on my xt master cylinder/brake lever. I had Trickstuff ordered so I bought the cheapest Shimano lever I could find.
It was the mt200 lever for $13 on ebay. Before my brake was all over the place with pumping and bite point issues.

Installed the mt200 and all the issues vanished. It's the same feel Everytime I pull the lever.
  • 3 3
 @WAKIdesigns: sold mine on eBay and bit the $900 bullet for Trickstuff.

Also replaced xt lever with bottom barrel mt200 lever and issues went away but not as much overall power.

My Trickstuff Piccola? They have more power then my xt.

With contaminated pads.

My Trickstuff pads front have been leaked on by my fork and still have more power and modulation then my xt.

I guess you would also fly over the bar's when you would use the Trigura or the Direttissima.

I never understood why people can't modulate their brake no matter what brake it actually is ...
  • 8 6
 @Serpentras: I haven't ridden Trickstuff but I rode Formula R1 and The One and these were impossibe to modulate with 203mm rotors and I'd argue The One were impossible to modulate even with 160 rotors. In wet on roots, they were just deadly. You would ride with your fingers on the levers, the bike would shake and you would hear your pads contacting the rotors, feel the brakes grabbing rotors with certain power being enough to unsettle the bike a bit in loose conditions. I don't know how the hell has Remy Thirion won in wet Andorra on fricking Formulas, maybe it was so muddy and wheels were rolling so slow he didn't need to touch these lethal brakes. It was possibly more impressive than Gwins chainless run. Whoever tried riding old Formulas with big rotors in the wet knows what I am talking about. And the proof to this is pictures of pros cutting the pads to decrease friction surface on their Formula brakes to make them brake worse.

I also do not understand what is the problem with having power under control, like older Saints or current Codes, why slamming brakes and feeling instant kick from the bike is considered as the desireable feature. I suspect it has to do with brake boilers/burners who just brake all the way down the mountain, ardously making brake bumps deeper, and deeper. That is my hypothesis. People replacing braking skill (possibly the most complex and hardest to attain skill in MTB after cornering) grabs instantly with zero effort, having less arm pump as a byproduct...

Modlation matters because the brake power is ultimately the max friction between your tyre and the ground. Who gives a hell how strong is your brake if you can't control wheels locking up or not, and in mixed dry/ wet conditions, like after the rain, when parts of the track dry up and some places stay slimy... good luck with on/off brakes.

 @chriskneeland: total misconception, shimano feel like they have a lot of power but don’t actually. Try doing a nose wheel with the front brake with a set of m8000 down a steep hill. They just feel grabby in the car park. Once you get some speed up there’s no real grunt behind them. Servo wave just moves the pistons fast.

 @WAKIdesigns: can't say anything about the old formulas.

 @vjunior21: I think you may have missed the point.
Shimano, being the massive corporation they are, have filled a patent for something (something they've no doubt done a million times, with only a handful of said patents making their way to production) which will be directed at a user group that ain't you and your buddies.
As far as affordability goes.. I've ridden all the good stuff (except for electronic) and I have to say Shimano slx really hits the mark for good performance and price. So I think they're also doing ok at covering that end of the market.
To that end I have to ask what it is that you're looking for when you say "more affordable." I know this particular sport isn't necessarily cheap, but you don't have to spend a lot or buy new stuff all the time to have fun doing it.

 Adventure Moto bikes have ABS (mostly) and the overwhelming option demanded by owners who actually ride them off-road is the ability to turn it OFF!
This is most likely going to be more of a road focused option. You need to be able to lock up a wheel and skid as terrain demands it when in the dirt.

 All the people bitching about sram and shimano hydros basically got me thinking “yup trp Magura or trickstuff” lol. I’d go hope but people bitching about those too lately. They key to maximum redness is knowing you can stop real quick when needed. When I rode my bmx brakeless I always noticed I’d go slower at things and when I went to clear pads on a chrome rim I was pedaling at stuff more cause I could stop stupid quick. Though my tires probably hated me for all the skids.

Abs is cool and all but what about when you want to lock your wheel? How are you supposed to do endo’s? Or badass tailtaps? What about the Canadians man, the friggin canadians man. Why have a front brake if you can’t do the occasional nosepick stall.

But seriously could be mad useful for preventing accidents but does pose some other limitations.

 This is an awful idea... especially for mountain bikes. It's unnecessary function and unwanted weight on road bikes and just useless in the dirt. Even on motorcycles, the first thing you do pulling off pavement is disable ABS.

 And yet on gravelly loose surfaces, like the type that most mtb are ridden on ABS is know to greatly increase stopping distances albeit with a lot of extra control.

It’s a partial myth that ABS improves stopping distances.

 Guide RSC's (4 piston), I Bought them used for $120, an they did in fact had the stuck lever issue (the seller didn't mentioned it) and at that time I wasn't aware of this problem, short story, I called worldwidecyclery, and they were able to warranty them free of charge. They told me they were the newest iteration (I'm guessing before the G2's) and I'm extremely impressed. With the contact adjustment I can make them feel like that "on and off" feel while also having the option of that "modulation". All in all, I got luck when I thought I had gotten ripped off at first, $120 for new guide RSC's was a come up.

 In 97 I worked in a shop when I first saw our local Skunk Works rider roll up on a bike with a first gen JUDY DHO triplecrown and Shimano Rollerbrakes. The protos with the huge cooling fins. They were almost ABS like in their performance. Personally I never got on with them. Something about them just felt off for me. But they did morph from WCDH equipment to some honestly quite good commuter brakes.

 To be honest I've thought long and hard about ABS on bicycles, and I don't really think it's worthwhile. I'm sure everyone said that when it was introduced to vehicles as well though. It just seems complicated, and burdensome on a bicycle, but then again there's wireless electronic shifting, so who knows..................

 I had a set of Guide R's on my last bike and thought they where okay but just lacking a bit of initial bite, the newer Magura brakes are pretty good though I had a set of MT5's and really couldn't complain too much

 I think it could really be a good thing for commuter bikes, but I like being able to lock up my brakes on some things.

 Forget ABS, invent a system that stops brake rub and I'll pelt them with credit cards.

 Forget ABS and anti-brake-rub systems. I want an Anti-OTB system.

 Am I the only one that wonders if this could be a benefit, but only as the FRONT brake for MTBs? If you only have the slightest amount of pressure on a brake and the wheel becomes airborne, that wheel can lock up. Think about braking bumps going into bike park corners. Seems like it could be a safety device, or even a training tool (assuming it makes some perceptible indication when its in use), specifically when learning NOT to brake too late into corners. Put it on beginner's bikes, or rentals. Might save a lot of collar bones and ultimately more time on the bike. But I also agree you need the ability to turn it off once you're up to it.

 Don't they also have a patent for a 14 speed drivetrain? I'm not worried.

 Bikes are like racecars. You don't want anything between you and the controls. This is a terrible idea.
Maybe on a road bike or a cruiser?
  • 1 1
 Racecars have a system of computers between the driver and car that would put Nasa to shame. There's regenerative braking and turbo waste both turned into battery power to feed electric motors at both rear wheels.

 @woofer2609: depends on the cars doesn't it? Did formula 1 go hybrid? It sounds like that's what you are saying. Formula E yes, but what about Indy cars? Rally cars probably have pretty complicated drive systems, I assume.
I know super cars are very high tech. Jeremy Clarkson told me. I also know he always had the most fun when he drives track cars. They all do, usually because there is nothing between them and the road except tire.
I also know my Prius has electric power steering, always on traction control, and brakes that take my input as a suggestion on any kind of bumps. I also know that I can have more fun in an old pickup truck on a dirt road than I can in a fancy machine that's shifting power back and forth from one set of wheels to the other. Don't get me wrong, I appreciate fuel injection. I also appreciate the idea of immediate throttle response coming from electric motors. What I hate is the big feel of most computer managed cars. My car being the worst offender I've ever driven.
I also know that if a dirt bike had anti-lock brakes I would cut the wire, same as I did my Subaru.

 @woofer2609: also, NASA has regenerative energy gathering systems on vehicles on planets that are very very far away. No I'm sure the Mars rovers don't drift, but I don't think they'd be ashamed to compare to any earthbound car when it comes to technical brilliance.

 Psssst, Shimano, maybe you want to focus some of your braking department budget on the migrating engagement point issue first? Or not.

 At the rate of development at Shimano, these will come out sometime in 2040

 Yes. Sram will release such system first. By that occasion they will change the caliper mounting standard to roadie flat mount and invent their own rotor mounting system. Fun!

 Clearly Shimano hasn’t tried driving or riding an ABS vehicle in the dirt. Nothing like losing all the stopping distance so your brakes don’t lock up.

 How do that make any sense?
I get not wanting it off road, but even in dirt skidding isn't slowing you down faster than controlled braking.

 Uhm.. There is no LIDAR. It's just an optical sensor to detect wheel slip. That being said. Sign me up for my MTB. And hurry up with Di2 XTR 12 speed.
