Mercedes Can Now Update Car Software Remotely 228

MatthewVD writes "Our cars run millions of lines of code that need constant and, often, critical updates. Jim Motavalli writes that Mercedes-Benz's new mbrace2 'cloud infotainment system' has a secret capability: it can update software automatically and wirelessly. In a process called 'reflashing,' the Mercedes system turns on the car operating system (CU), downloads the new application, then cuts itself off. With companies like Fisker paying dearly for constant recalls for software problems, automakers will likely rush to embrace this technology. No more USBs in the dashboard!"

    From the Mercedes site:

    Remote Vehicle Diagnostics Beyond allowing you to perform a check of your vehicle's main systems remotely, mbrace2 technology can automatically alert both you and your authorized Mercedes-Benz dealer to potential issues before they become full-fledged problems. In addition, it enables your vehicle to receive software updates wirelessly through the mbrace2 network.

    So while maybe undesirable, not sure it's 'secret'.

        If this were not the manufacturer of the car doing this, I might have thought the same thing you are thinking. But if people begin to get troubled with too much recommended maintenance, they will start to believe their cars are unreliable and will not buy another one... or at least not one that tells them things they don't want to know.

          Are you paying for "reliability" or "Government-regulated mandatory safety upgrades"?

          "Repairs" can be spun many, many different ways...such as the difference between optional and mandatory types of insurance. People hate paying for either type of insurance, but don't see much of a choice when it's "mandatory". A "cost" turns into a "fee" if EVERY car owner is charged for it, so this is yet another vehicle to mandate mass fees, turning profits through "safety standards"(for both the auto industry and Government). But you somehow feel better about it, because your 37 air bags are all up to date with the latest software patch and ready to protect you (not that they didn't before).

          Oh and your insurance company feels better too, because they got a piece of the profits as well by mandating that no car will be insured without an "active maintenance subscription". Oh yeah, you'll need auto anti-virus protection too.

          (I mean seriously, what do you think auto and insurance lobbyists do all day?)

            Given that most new cars have a period of maintenance factored in where the owner does not pay for warranty work (often 5 years), any warranty work performed like software updates simply come right off the companies bottom lin.e It only makes good business sense to make this as inexpensive as possible and if they can do updates remotely without actually going into the dealer then this is a huge cost savings for them and far more convenient to the owner.

            Also, given how much of the safety systems on these high end Mercedes are under software control, I wouldn't be surprised if the lawyers are warning the company that if they do not do due diligence in rolling out safety related upgrades, then they may be liable for crashes related to the failing of this software. In such a case making sure the software updates are rolled out to as many people as possible as easily as possible would be a mandate of theirs.

        • I wish I had your faith in my fellow human beings, but most people do not seem to care about reliablity when they purchase their cars. Mercedes is one of the more unreliable brands on the market and they are still managing to sell plenty of cars. Even worse, look at Dodge/Chrysler, unlike Mercedes, they have always had a reputation for poor reliability and they are still managing to stay alive.

      20 miles per hour speed limiter? How about limit it to just under the speed limit (since GPS's seem to be able to get that these days). It will effectively piss off people in a lot of areas such as Massachusetts (I have gotten passed on a double yellow there for going slightly over the limit...don't underestimate how much this would piss off Massholes). The 20mph limiter would just make the driver be like "FUCK THIS!", a GPS based limiter could troll the driver and everyone around them in the right areas, at least for a little while.
      • In many areas of massachusetts, speed limits are not set at the speeds the roads were designed for/are safe to operate at, but at revenue generating levels - speeds at which police officers on speed patrol can spend their whole day writing tickets.

        Enforcement is still lax, though, because if enforcement was efficient, people would drive at the lower levels to avoid it. Effectively, mass does not have speed limits. It has a "random road tax."

I'm assuming it would do it via 3g actually too. it wouldn't be too hard for mercedes to negotiate europe wide contracts for it for fairly cheap(the data amounts will be rather low). so it might be something like 200 bucks for 3 years of updates, which considering the total cost of the car isn't really that much. if it can prevent one recall for a model that would otherwise need the dealer to do "free" work billed to mb then from mb's viewpoint it's a good deal.

      If it works like the iDrive system in BMW, the ECU stays active for about 10 minutes after the car is turned off, in order to remember navigation position and the creature comfort stuff like heated seats being turned on. Mercedes is likely putting this update check in after such an interval.

      As for the brake and tire wear checking, that's done by a Mark-I eyeball installed in a service technician at the dealership, which is included in the service plan that comes with the car.

And that the data will be sold to marketers who can compete for the chance to market new synthetic oil to you starting a thousand miles before the suggested oil change, or new tires when the ones you have approach their life.
