[@AngeTheGreat]

SiliXcon is planning to film some riding footage once the onboard speaker is sorted out. Let me know if you guys are interested and I’ll keep covering this project on my channel! There are some glitches in the audio and I know it sounds more like a woodchipper than a dirtbike right now. This is a very early prototype with an ancient version of Engine Simulator running on a microcontroller which is not exactly a Ryzen 9...

[@BigJim1976]

Absolutely! While I'm not too intrigued by EV's myself, this is an interesting collide for them, and I'm interested to see how this may turn out.

[@Supreme_Lobster]

[@Stork2204]

@@Splarkszter that'd be sick honestly

[@MistahHeffo]

@@jwalster9412 You missed the critical point.. There is a feedback loop between engine simulator and the real world... Engine Simulator produces not only the audio, but also the Torque values that need to be applied to the wheels, which gets sent to the electric motor which is capable of producing that torque. Then, any resistances from the real world are measured and fed back into engine simulator so in theory if you start climbing a very steep hill then engine simulator will bog down trying to climb said hill, and even stall if you push it too far.

Exiting stuff.

[@AcrobotMovies]

[@fiery_transition]

Dude, you should make more educational materials in general :-D Love your presentation!

[@AngeTheGreat]

Thanks 🙏 I just wish it wasn't so time consuming, otherwise I'd do more content like that

[@ZundappBackSlap]

One thing that this could be extremely useful for is safety. Bikes can be more difficult to spot due to their smaller size, the only thing that confirms their presence on the road is the engine noise. Now that companies are trying to implement EV motorcycles, I have thought about the increased danger of having silent, fast, small two-wheeled vehicles sharing the road with cars. I honestly feel like the implementation of noise generation on small EV's can help keep the riders safe.

[@DFPercush]

High vis gear helps too. It's required on US military bases. I know the saying "loud pipes save lives" though. Only problem is when some dude's thunder Harley turns left past me at an intersection and he gives it the beans, blasting me with 130 dB and hearing damage. That's just rude. If that sound could be focused towards the front, it would make a lot more sense.

[@martinschroederglst]

At first, I thought that this would only be about sound, but it is so much more! Also, it's nice that a program that Ange wrote solely for his personal entertainment (and flexing of cause!) suddenly has applications in the real world!

[@faf..]

That dirt bike prototype is sick. I wonder how close it feels to the real thing when riding.

[@nomindseye]

What do you mean? Electric Dirtbikes are old news by now? I've driven a few. They're pretty bonkers. Instant power and torque at any second you want. You get an hour maybe more out of them, at least when I rode them. It's been a few years now though.

[@phoenixdonner8553]

@@nomindseye yeah, but the torque and power is from the engine simulators simulation meaning the bike behaves more like a gas powered vehicle. The electric motor is used to sync up the simulation and the real world drive system.

[@nomindseye]

@@phoenixdonner8553 aah, yes. You're right, I didn't think about that aspect. For some reason, even though it's more or less the point of this video. My bad. It's a good question, actually. Probably not quite like what the real thing is, because suspension geometry and size of the bike probably don't match - if you're aiming for a specific bike. But at least in theory, if the electric engine is more powerful than what it's simulating, it's going to be pretty damn close. Of course, the only difference between theory and practice is than in theory there's no difference. Personally, I'd like to have a rotary in my electric dirtbike. Because that is what this technology is for.

Damn, having ev's be able to emulate old engines is a really interesting perspective. Imagine being able to emulate an old lambo v12 but in some shitty modified hatchback, and it being actually accurate by making some wheelspin past 6.5k rpm

[@televisionandcheese]

I think using engine sim to control real world EV's is a fantastic idea, not only will it help keep the joy of using combustion engines and manual transmissions, but it also provides a genuine great use case in that; it can provide an excellent analogue for how to control regen breaking in a EV on the fly :) Normally in our real cars we can just change down a gear to get a braking effect without using the brake pedal, and I feel like this same idea can be applied to a EV with a fake gearstick, where it uses the gearstick and the theoretical engine's rpm and loads to calculate how much regen braking to apply It's far more ergonomic and familiar to existing drivers to change down from 5th to 3rd gear to get a decent amount of engine braking, more than they'd get in 4th and considerably more than just letting off in 5th, and can be done on the fly with ease, rather than needing to edit the engine braking intensity in a menu on the silly touchscreen or using a column stalk that has 3 positions or a switch on the centre console that does it through the whole driving mode of comfort/sport/etc

[@furankusama]

[@besknighter]

Mind? Blown. Jaw? On the floor. Socks? Blown off. I'm REALLY impressed by this. OMG. Maybe it's possible to hook a FPGA and do a convolution reverb on the signal right before the DAC and have it simulate the exhaust? Maybe having the impulse response also swappable. If someone with the tools could try that and it works, EV companies could combine what is shown here with a developed DAC with an embbeded Reverb Convolver as an SoC. We would have EV vehicles that drives and sounds exactly like combustion vehicles. And you can drive whatever engine and exhaust, reallistic or not, you heart my desire.

oooo man I'm so happy to see your channel grow so quickly, you definitely deserve it! All the best

[@Chevsilverado]

one of the biggest problems I’ve had when riding an electric bike is that the powerband of a combustion engine is very important for fine control of the bike. You’re constantly manipulating the clutch and rpm to put down the proper amount of torque so you don’t spin the rear wheel. Different engines have a huge impact on how you ride the bike and there’s a lot of personal preference. To be able to emulate a realistic torque curve of any type of engine would be amazing. The audio feedback is also a huge part because it tells you what state the engine is in and if you can’t hear the bike it’s really weird to ride the bike. You even get this going from a 2 stroke to 4 stroke bike, as the 2 stroke bike has a much more reactive sound and the 4 stroke sounds like it’s constantly bogging in comparison, and it’s hard to tell if you’re near the rev limiter if you’re used to 2 stroke. Basically, the first time I rode an electric bike it was hard to control the torque on tight trails, and even using the artificial torque curve option it was still strange and not quite as “usable” as a combustion engine. Plus the fact that you couldn’t really hear how hard the bike is working it was not as good as a combustion bike.

[@gabrielracz4210]

[@bytesandbikes]

4:52 Ha! Real clutches in cars have springs for the same reason! In bikes, there's a rubber buffer in the back wheel

[@blackbriarmead1966]

I've been thinking this for so long. I don't have a particular attachment to gasoline-powered engines, I just have an attachment to the sound, vibrations, and method of control (manual transmission). With the right speaker systems, a vibration motor, and a simulated manual transmission, it could be possible to create an emissions-free experience that could satisfy people who like these things. I get criticism because people are like, what's the point in simulating an obsolete technology just because that's how it used to be? My point is, if we're going to transition *everybody* to EVs, this would be an absolutely great way to give those who would otherwise be very reluctant an option that is just as exciting as a supercharged V8.

Simulating a gas engine with all the physics involved would actually make for a similar experience with the added bonus of being able to simulate any engine you like. Imagine this also in cars, simulating V5 or V10 engines. The possibilities this would provide are incredible. Also, my advice - keep this open source but put a good license on it that makes it impossible for big EV manufacturers to use this without properly licensing it from you. I can already see this becoming a huge thing a few years in the future.
