Software-Defined Vehicles Will Dominate At CES (computerworld.com)

Posted by Soulskill on from the please-don't-let-people-tweet-at-nearby-drivers dept.

Lucas123 writes: Carmakers and their tier 1 parts suppliers at CES in January are expected to launch an unprecedented number of software advances centered around cloud services and over-the-air updates. The number of in-vehicle processors continues to grow, and consumers have come to expect their car to mimic smartphone functionality. As hardware becomes more of a commodity, increasingly cars will be defined by software. There will be about 464 automotive electronics exhibitors at this year's CES — a record number, according to IHS Automotive. Human-machine interface will be a core technology at the show — augmented reality and virtual reality, in the form of gesture recognition and heads up displays, are expected to be among the most cutting-edge features.

Cloud-based speech recognition technology that uses machine learning skills to identify speech patterns more quickly will also be more commonplace. One development the analysts said they're "crossing their fingers" to see at the show is Modular Infotainment Platforms, which allow carmakers to offer the latest electronic systems prior to a model launch. Today, car models are often launched with years-old electronics. Apple's CarPlay and Google's Android Auto are also increasingly undermining the native infotainment system makers' business. Analysts believe all carmakers will eventually offer both APIs in future car models.

The only problem I've had with power windows were in an early-90s model Honda where they were really slow at times, and that was mostly because back then they still used the shitty scissor-type regulator mechanisms from hand-operated windows. Sometime in the 90s or so, everyone finally switched to the newer mechanisms where the motor sits on the window and raises it up and down a cable. They stuck with the shitty regulators for a long time because when they still made manual windows, it was cheaper to reuse the mechanisms between both types, but the new type is far more mechanically efficient and not prone to binding the way the old one was, so when manual windows became completely obsolete they finally abandoned the old mechanisms.

      Unless your car is pretty old, it's already heavily driven by software. Electronic Fuel Injection? The venerable timing chain/belt has been replaced by software, and it's software that is pretty smart about when to inject fuel and fire the spark plugs, constantly varying the timing by small amounts as engine demands change, and based on real-time reports from various sensors. Anti-lock brakes? Software. There's probably software embedded in your transmission. I drive an electric car, and there's very little of it that isn't software-controlled.

      All of that software is actually a big part of why vehicles today are safer, more reliable and more fuel-efficient than they were in decades past.

      But I also don't like suffering the death of a thousand cuts with small things going inexplicably wrong in a car all the time either.

      Software is inherently more reliable than hardware, since it doesn't wear out. What makes so much software bad is the fact that it's feasible to build stuff that is several orders of magnitude more complex than anything we'd attempt with hardware. Complexity is the enemy of reliability. On the other hand complexity enables us to do more, and better. So the key is to manage the complexity appropriately; minimizing it where possible and thoroughly validating it where the complexity is actually necessary. This is totally possible. The aerospace industry uses a tremendous amount of software, and makes it highly reliable.

      The automotive industry isn't very good at software, but in practice I think that's less of a problem that it appears, because the software that actually runs the parts of your car that are really important isn't very complex at all compared to most software systems, and applying standard hardware testing methodologies to the combined software and hardware works pretty well to flush out the problems. So, while there are problems, they tend to be relatively minor and obscure.

      In other areas, like entertainment systems, automotive software tends to suck. Partly that's because it doesn't get the same level of testing, but mostly it's because testing isn't good at identifying user experience problems.

      Security is also not very testable, and is another area where automotive software tends to be awful. Thus far that hasn't been a problem in practice. It's the one area that really concerns me.

In all cases I can still see what's actually out there as well as my eyes will allow, and everything else other than possibly urgent warning indicators is just a soft/transparent enhancement of the natural view.

    I have never heard *anyone* say this, ever. Integration with smartphones: yes. *Replacing* a smartphone: nope, not at all, ever, no thanks. Am I just behind the times, or is this more like how consumers have supposedly come to expect 3D and/or ultra-4k tvs that nobody actually needs or wants?

  17. Who wants this garbage in their cars? by halfdan+the+black · · Score: 1

    I sure as hell don't, all I want is a big tach right in the middle, a speedo, gas, temp and boost gauges off on the side. I just want manual heat/ac controls and nothing else. Basically all I want is a lightweight car with no crap on it, manual gearbox, rear wheel drive, multi link suspension, low center of mass, lots of power, good sounding exhaust, and good looks.

    I've got no use for tarting a car up just for the sake of tarting it up. I drive a Honda S2000, and I think I might have literally turned the radio on once since I've owned the car, when the exhaust sounds this good with the top down, who needs a radio.

  18. Software is not inherently more reliable by SuperKendall · · Score: 1

    Software is inherently more reliable than hardware, since it doesn't wear out.

    Yes, I know all about how much tech is already in modern cars - I wouldn't get rid of all of it, but there are already interactions I dislike with what is there. Sometimes glitchy acceleration because of fuel injection. Automatic shifters that shift at bad times. I'm just saying that after some initial large wins by adding software, adding lots more on top seems to cross into the realm of dubious value.

    Software is in fact inherently LESS reliable than hardware, because hardware generally fails gradually, in ways that can be predicted and checked ahead of time for (like checking for cracks on a belt). Software though, either works or generally fails spectacularly - because of two factors - one is that storage wears out or gets corrupted sometimes, the other is that sensors fail and with bad input comes our friend GIGO.

    Software is inherently less reliable because with a complex enough system you literally cannot predict what an infinite combination of partially or fully failing sensors and electrical connections will mean with software behavior... with mechanical systems the failure also generally is fairly isolated, while with software failure is much mire likely to be broad in scope.

Software though, either works or generally fails spectacularly - because of two factors - one is that storage wears out or gets corrupted sometimes, the other is that sensors fail and with bad input comes our friend GIGO.

      Having binary failure modes (either works or fails spectacularly) makes it more reliable, because (assuming comparable complexity), hardware has more wear modes. The only reason you think those can be predicted and checked ahead of time is because you happen to know the common ones. If worn out or corrupted storage is sufficiently common then it is even easier to check for... in fact the software can (and often does) do it automatically in a power-on self-test.

      The only case where that breaks down is when the hardware running the software fails. That could be addressed with redundancy but generally isn't in automotive applications (unlike aerospace applications).

      Regarding sensors and GIGO, those issues also plague any purely hardware implementations that rely on sensors of some sort. It doesn't matter whether the sensor response is analog and mechanical or computerized and digital. Further, it's much easier for software to detect and work around garbage. In fact, this is exactly what a lot of automotive software does. For example, if your O2 sensor goes out and starts reporting garbage, the software recognizes the failure, attempts to work around it to keep things running somewhat well and flicks on the "check engine" light. If you then connect to the OBDII interface, it'll give you a failure code telling you that the O2 sensor is bad.

      Software is inherently less reliable because with a complex enough system you literally cannot predict what an infinite combination of partially or fully failing sensors and electrical connections will mean with software behavior... with mechanical systems the failure also generally is fairly isolated, while with software failure is much mire likely to be broad in scope.

      This just another way to state the point that I made, that software allows us to reach for much greater complexity than mechanical hardware does. Mechanical solutions tend to be simpler because complex ones are dramatically more failure prone and harder to test and debug than software solutions, as well as being harder to build in the first place. So it's not software that is unreliable, it's complexity. But complexity can be managed and minimized in software, as long as the effort is made to do so. And, actually, automotive software in reliability-critical components is pretty good at this.

      Software is inherently more reliable than mechanical hardware, at comparable levels of complexity. It doesn't wear out, has fewer failure modes which are easier to understand, can identify and adapt to hardware failures in ways that mechanical solutions cannot and can more directly and accurately report identified failures. Further, those characteristics mean that software can be more reliable than mechanical hardware even when the software is somewhat more complex.

      I can't read the rest because this is too wrong.

      Those "more we are modes" mean you can drive somewhere because something is partially working, instead of being stranded because software has decided you cannot.

      You aren't considering what failure means, what benefits partial failure yields in relation to sometimes life and death situations.
