How Do We Control The Car? | COMMA_CON

[@chandu527]

This is one of the best pieces of documentation of the Comma system. I have been searching for this info for so long in discord but it's all bits and pieces. I think we need to start an open-source project for documenting the information. The more clear the documentation is, the more people can contribute to it.

[@philippelaferriere2661]

Finally, a conference that understands that both the speaker AND the slides are important when watching a talk.

[@alexk6275]

Next presentation: "How do we contral the presentation clicker?"

[@traveller200x]

It's an issue with these slide advancers. They have a very limited range. They should've used a Perfect Cue. Basically a slide advancer on steroids, with a much longer range!

[@mc333777]

COMMA TEAM ROCKS! These guys works very hard to help all driver(less), and make driving chill. Thank you.

[@gudenau]

I was really hoping for more archived talks! Hopefully if you do more of these I'll be able to attend one.

[@drewski23_7]

So awesome to have someone so knowledgeable about this answer questions!

[@michaelm9621]

This is spot on what I need to know. It looks like they put a lot of quality thought into the Comma.

[@user-zi9uz3df8c]

Love my comma3. Really does change driving for the better!

[@eaojnr]

This is really animpressive piece of feat. It is the "Peugeot" of the "autonomous car" space.... *simple, practical* and functional engineering for reliable mass market adoption.

[@raghuparedla362]

Companies like these must grow (that make FOSS components and make business) and then the ecosystem will eventually force car manufacturers to adopt standard interfaces for plug & play and also to get diagnostic information much easily.

[@nyrubin]

Toyotas lane centering works really well, when it does. Hyundai lane centering doesn’t work really well but it’s usually always working even off the main road. I just ordered the comma 3x hoping it’ll engage better then the stock steering on the Tucson phev 😁

[@khoahuynh6884]

Great tech! soon car makers will enhance their security and people just can't inject devices into the system anymore. Same thing as jailbreaking your iPhone. It becomes harder and unnecessary. But it's like 10 years scenario from now, and I hope the company gonna grow to be something bigger at that point.

[@kronikal_insideus]

Layman can understan it.. Kudos comma team

[@rtrt2889]

Any plans for 2021 RAV4 Prime?

[@MrPhil45]

Lack of Flexray support really kills it for most if not all German cars. Such as shame there isn’t more work being done on this.

[@robindobbermann]

When you have connection to the other systems.. Like climate control or infotainment.. I think there is a great opputunity to the people from the open source community to make "apps" for the platform like.. Preheat the cabin from the connect website, when using the comma three with LTE and stuff like this.. Or open / close the car, battery status remotely. Because I miss these features very much on my Hyundai Ioniq 2019 vFL, because in Europe the Ioniq vFL hasn't the BlueLink connectivity and I miss them very much. I think there are a lot more cars, that has the problem. In Germany alot of the cars from Stellantis (Opel, Peugeot etc.) with begin of the next year, because they kill the plattform. Even for newer cars like a 2022 Peugeot e208.

[@klauszinser]

Thats a good point. Maybe this should go through an API to have some control. They kill the BlueLink platform?

[@robbiewadley5097]

How old of a car could openpilot hypothetically work on? Is a LKAS camera absolutely necessary? Could it potentially ever even work on cars without a built in LKAS?

[@grekiki]

Absolutely. If you want to do custom actuators you can make it work on cars without CAN like a 1990 VW van which someone managed to get working. But even with the stock actuators, I got a Caddy to work that has a manual transmission and no adas like not even cruise control

[@foley2k2]

Lane-keep is older than you think. I have a 2014 Prius with radar cruise and lane keep.

[@Radiant-hf2vh]

@@grekiki how were you able to control non lkas car ? external actuators or eps retrofit ?

[@grekiki]

@@Radiant-hf2vh Recoding the EPS to convince it that it has LKAS via VCDS

[@klauszinser]

@@grekiki I was thinking about this - having a Renaut Twizy and an Audi A2 in mind - when watching some videos. Both with CAN bus but a Mercedes S124 does not have this. One is the steering. I suppose with power steering soon afterwards CAN Bus control was implemented. It's not there with the Twizy. (Traktors is a separate issue but for field work they added steering and an accurate GPS). Another very important interface is brakes. Nearly for sure not there with the Twizy. Electric Re-Gen is not enough. For the Audi A2 which was built from around 2000 to 2005 both, Steering and Brakes need to be figured out. Re brakes, it could be there is information because of ABS. The DBC build tools here will get very interesting.

[@eaojnr]

excellent demeanor answering those questions, and poignant answers. Enjoyed it very much!!!! Any chance for evasive maneuving capabilities in next iteration of comma?

[@mayureshsavargaonkar4694]

What happens when the stock AEB requests a deceleration for more than -3.0m/s2 ? Does the panda filter it or pass it through?

[@abdulrahmanabdurrab9391]

good question. I think AEB messages are passed through.

[@Kefford666]

The panda just filters messages going from OpenPilot to the car so it wouldn’t affect the cars built-in systems. The STM32 would receive a USB packet, analyse the values and then either create a CAN message if the values are valid or discard it if not valid. Might send a NACK back on the USB port. Messages already on the CAN bus would be received by the STM32 but it has no control over those.

[@taumax]

Seems like OpenPilot might be screwed when OEMs start implementing message authentication on their CAN communication networks. How long before this happens?

[@hug0hq]

29:40 "I break it if I need to"

[@reallyiffy]

They may force a royalty or something for signing, or refuse to entirely. Wouldn't put it past them.

[@taumax]

@@reallyiffy I'm think OEMs will eventually block this because of liability concerns and possibly prevent a competitor from their inhouse AV solutions

[@domtef347]

​@@taumax what liabilities?

[@rickyliu1454]

As long as comma does not change internal code for all supported cars and all auto companies will not do anything at all . They know open-pilot is helping the legacy auto companies in the world currently.

[@anibalcutinella4481]

hi i have a dfsk seres 3 and i want to know if works with you're hardware . thanks

[@JustWasted3HoursHere]

It seems like everyone except George had a problem with that $&@# clicker. LOL.

[@iTzDeadshadow1]

When would be Available for other make and model?

[@AdamSPARTAN76]

It already is. Check their website

[@jrein59]

Comma is great for right now but I see comma ending up being swallowed by a car manufacturer the functionality of openpilot is starting to be released in regular cars Ford blue cruise…Cadillac super cruise these will improve and will trickle down to lower priced vehicles leaving comma without a market unless they allow themselves to be swallowed by a specific manufacturer and build their system for them… agin I love openpilot and have it in my car but I don’t see a future for the company as a stand alone entity because automakers are starting to hardwire this functionality into their vehicles

[@Wanderlust1972]

its for people who cant afford those cars

[@Ludix147]

Well they do try to compete on quality, i.e. make a better system than OEMs. That will be hard to keep up in the long run though.

[@jrein59]

@@Ludix147 the problem isn’t the quality it’s the fact car manufacturers are starting to include similar technology from the factory no ones gonna buy from comma if their car already has a level 2 system built in

[@Upstatecashew]

is there going to be a future option for navigate on openpilot ?

[@thomasre8073]

Yes, George has announced that in the comma three presentation.

Which device class are you using for the STM32 USB? Is CDC fast enough, or did you use HID or mass storage, or did you have to develop a custom class?

[@akramsamuel9774]

Does anyone know how this unit deals with the cars baseline saftey features? The emergency breaking for example? When you tap into the adas system is the link between the adas and the cars saftey features broken? Or do all the saftey sense features still work as per factory settings?

[@sirgizmo440]

Can this work on Mercedes anyway?

[@vikramgupta5787]

Future cars are moving towards CAN over ethernet. How are you guys preparing for that?

[@amilamad]

What happen when car makers encrypt the message ?.

[@yanushkowalsky1402]

are messages on canbus actually ever encrypted or is this hypothetical question?

[@andre824]

Whatever you DO NOT waste your money on the comma!!! I'm sure it's just as cheap and nasty as the Comma 2 which started failing just after a year. 2kAUD down the drain 3kAUD down the drain if you buy this one. Plenty of other people with the same issue on reddit and discord. Crappy 1 year limited warranty with barely any support. Even their support page says we won't help you if they think it's something you should be able to fix yourself. Their online help they refer you to is a discord which has a similiar mindset...smh

[@aftdawn]

This is a tool for tinkerers, not for the laymen, if you have issues that they think you can fix but you can't, knuckle down, learn and stfu
