    GM Next Gen Ultra Cruise to enable Door-to-Door Hands-Free Driving with New Compute Architecture

      GM's multi-cultural global engineering team with American Semiconductor company Qualcomm Technologies to usher in the next generation of Ultra Cruise with robust door-to-door hands-free driving in 95 percent of all driving scenarios.

    Years of collaboration between GM and Qualcomm has brought many robust industry leading features to GM's autos globally. Now GM and Qualcomm have moved forward again in showing their collaboration of the first dedicated Snapdragon system-on-chips with robust data processing for the next generation of Ultra Cruise advanced driver assistance system.

    GM will be the first auto company to use the Qualcomm Technologies Snapdragon Ride Platform for advanced driver assistance technology. This features an industry-leading 5-nanometer Snapdragon SA8540P SoC and SA9000P artificial intelligence accelerator.

    This is not the first time that engineering from the U.S., Israel, Canada and Ireland have worked on a global version of Ultra Cruise. In the upcoming 2023 Cadillac LYRIQ we get the first generation of Ultra Cruise with Snapdragon. A very solid Level 3 hands free driving on the highway. Yet GM is pushing itself to become an Auto industry leader of technology and with its Collaboration with Qualcomm and the in-house engineering resources the next generation of Ultra Cruise will be on the all-New Snapdragon Ride Platform which is about the size of two laptops stacked together and will debut on the 2023 Cadillac CELESTIQ.

    The Ultra Cruise computer is a high performance sensor interface with memory bandwidth running the Ultra Cruise software stack that will be the key in helping Ultra Cruise achieve an unmatched combination of capability, reliability, predictability and robust door-to-door hands-free driving in 95 percent of all driving scenarios.

    Ken Morris, GM vice president of Electric, Autonomous and Fuel Cell Vehicle Programs has stated: “Despite its relatively small size, Ultra Cruise’s compute will have the processing capability of several hundred personal computers,” “It will take qualities that have distinguished GM’s advanced driver assist systems since 2017 to the next level with door-to-door hands-free driving.”

    Ultra Cruise compute platform

    The newest Ultra Cruise software has been integrated into an optimal hardware design that starts with the Snapdragon Ride Platform and goes on to use a combination of overlaying cameras, radar and LiDAR. This low-level, sensor fusion, which provides excellent detection and classification of data, and the Ultra Cruise's software stack are a proprietary package not available to the automotive aftermarket and surpasses any hands-free system offered by any other auto company here in the US, Europe or Asia.

    The Ultra Cruise Computer system is comprised of two Snapdragon SA8540P SoCs and one SA9000P AI accelerators to deliver key low-latency control functions on 16-core CPUs and high-performance AI compute of more than 300 Tera Operations Per Second for Camera, radar and lidar processing. The Snapdragon SoCs are designed with 5 nm process technology, enabling superior performance and power efficiency. The Snapdragon SA8540P SoCs will provide the necessary bandwidth for Ultra Cruise's sensing, perception, planning, localization, mapping and driver monitoring.

    GM and Qualcomm are very proud of their global multi-Cultural collaboration in the first uses of the Snapdragon SoCs platform for automated driving. To quote the press release: “Ultra Cruise powered by Snapdragon Ride on Cadillac vehicles will be an experiential and technological leap forward for the industry.”

    Less people look to the past of new technology problems, the Ultra Cruise compute on the Snapdragon Ride SoCs have been designed to meet automotive system safety standards with multiple individual redundancies built in. The compute platform includes an Infineon Aurix TC397 processor for system safety integrity. The Aurix TC397 is categorized ASIL-D the highest Automotive Safety Integrity Level.

    To minimized complexity, the Ultra Cruise Snapdragon Ride Platform has been designed with air-cooled instead of liquid-cooled system to avoid heavy and inefficient thermal cooling lines throughout the auto. This has been made possible by the Snapdragon Ride's high-performance, high-efficiency design. 

    Less people feel this will be a limiting system of updates, GM choose to incorporate the Ultra Cruise's computer with the ability to evolve over time by leveraging the Snapdragon Ride's SoCs performance and high-speed interfaces for future expansion, including over-the-air updates that can include new feature/functions enabled through the Ultifi software platform and GM's Vehicle Intelligence Platform electrical architecture working with the Ultium platform to bring you the industry best auto's.

    Qualcomm had the following additional technical information in their press release to expand on what GM has released about the Snapdragon Ride Platform.


    The Snapdragon Digital Chassis is comprised of a set of open and scalable cloud-connected platforms that utilize a unified architecture to support enhanced safety and immersive digital experiences that are updateable throughout the lifetime of next-generation vehicles.

    Its a very SOLID level 3 tho...  (on the highway)

    How solid you asked, again?

    A VERY solid.  But on the highway only.   Maybe.   No, for sure.  Because its a very solid #3.

    Unproven technology with no driver override.  Possibly very dangerous.  YOU go First!

    According to GM's self driving division I see they have been testing the Snapdragon Ride platform in the bolt driver free taxies in San Francisco. Will be interesting for sure and I have to believe their will be a driver override. That just makes common sense.

    All I can say is; MAN are the tesla forums filled with outrage over the FSD scenario. Tesla just announced a 20% (let’s call it) market adjustment for the package, up from $10K (it once was $4K), to $12K, plus the MONTHLY CHARGE is also going to go up from the current $200.

    Let's not forget that Tesla pulled their LiDAR and Radar as they feel they can do full remote door-to-door with cameras only. They have already made a mistake by making the system cheaper in components while increasing the cost.

    Many coworkers who do have Tesla have bitched about the price increase, the technology weakening of the safety ability and that there is no longer the ability to get certain features in a lower cost package, if you want self-parking or the safety sensor reading while driving or backing up, you have to buy the full self-driving package.

    Overall, I would trust GM package of camera, Radar and LiDAR over Tesla any day.

    And if you sell the car to a new owner, it gets disabled.  Which seems like a total scam to me.  If you pay for a feature on a car, it should be there forever.

    These semi-autonomous systems that are level 2 and 3 I think have really little value to the consumer, especially not what Tesla wants to charge for it (when all the level 2 self driving stuff is standard on and S-class).  They do have crash avoidance, which should help reduce accidents, but at the same rate 2021 was a record year for accidents and traffic fatalities, even though cars are putting all this tech in.  

    Mercedes Drive Pilot is the first UN certified level 3 system, it is cleared for use in Germany, looks like they are working on America and other markets, but need regulatory approval.  I couldn't find a price for it, or if that will be standard, I am sure it won't be $12k like Tesla charges for a level 2 system.  

    If Ultra Cruise can deliver, this is a chance for GM to make it standard on all Cadillacs and stick it to Tesla.  At the least Super Cruise should be standard on all Cadillacs, and Ultra Cruise not a $12k option.  And Super Cruise has a monthly fee, I think they need to get rid of that, OEM's can get data and utilize that for profit like Google does.  I don't have to pay google to use their search or email, because they know how to monetize data and make money of things there are free to the consumer.

    • BBQ season has begun!!! I decided to on Saturday make baby back ribs. I decided I wanted to do two types of ribs, a traditional honey BBQ sauced ribs and one based on a Korean Spicy Pork dish which uses Gochujang which is the base of the sauce. A Gochujang BBQ sauce. To make sure the ribs were tender and juicy, I had been doing research on Brines. Wet Brine: 6 cups water, divided 1 (12 oz) light beer or imperial 1 cup apple juice or cider 1 cup dark brown sugar (sub light brown sugar if that’s what you have) 1/2 cup Kosher salt1 tablespoon granulated garlic1 tablespoon granulated onion 1/2 tablespoon Chinese 5 Spice 2 cups ice cubes I bought 10lbs of baby back Prime ribs from business Costco, so I doubled the Brine batch to ensure that they were well covered. I used two 19oz IPA Indian Pale Ale from DESCHUTES brewery. I then salt and peppered two racks of ribs and used my pork rub on the other two racks of ribs. I then wrapped them in parchment paper, covered with foil and back into the fridge for another 24hr nap before grilling them slowly. I have to say they came out very tender, juicy beyond compare, best ribs I have made yet, 250, slow go for almost 4hrs using only the outside two burners on my grill. The traditional ribs were awesome with a nice sweet sauce. The Gochujang BBQ sauce is a spice lovers dream. Darker than the traditional sauce in the pictures, this sauce was put on the salt n pepper ribs. Rich deep flavor, spicy, tender and the bones were left clean. For those wanting to try this sauce on their ribs, here is a very similar recipe that my wife has made as everything is in her head. https://www.koreanbapsang.com/dweji-bulgogi-korean-spicy-pork-bbq/ We add red pepper flakes to kick up the heat, make it as thin or thick as you like, adjust to personal taste.  
    • Missed that in my quick look while catching up on work from PTO.
    • Agree comfort should always be in Luxury Auto's foremost, but sadly brand name bragging has made things less so. I have no problem with the thinner seats that are made in the Escalade as long as they offer comfort, sadly the thinner seats are hard as a rock limiting road trip comfort.
