Tesla Teardown Reveals Driver-facing Electronics Built By iPhone 6 Suppliers 158

Lucas123 writes: The Tesla Model S gets attention because it's an EV that can go from from 0 to 60 mph (96 km/h) in 4.2 seconds and can travel 265 miles on a single charge. But, a teardown of the vehicle by IHS Technology has also revealed that Elon Musk avoided third-party design and build routes used traditionally by auto makers and spared no expense on the instrument cluster and infotainment (head unit) system, which is powered by two 1.4Ghz, quad-core NVIDIA Tegra processors. IHS called the Tesla's head unit the most sophisticated it's ever seen, with 1,000 more components than any it has previously analyzed. A bill of materials for the virtual instrument cluster and the premium media control unit is also roughly twice the cost of the highest-end infotainment unit examined by IHS.

          The car clearly lacks enough sensors to become truly self driving. How is it going to avoid changing lane in front of a faster moving car, when it has no rear facing sensor with longer range than 12 ft? How is it going to tell the difference between a pole and a child on a bicycle before doing a right turn, when it only has simple sonar sensors in that direction?

            • by ihtoit ( 3393327 )

              preheating isn't needed with modern diesel mixes. Some pump oils (such as used on the Dalton) will start at -35C. #1 diesel turns to wax at -40C and will still turn over in a fairly well maintained engine at -20C. Should you find yourself in a situation of needing to start an engine in -50C like they do at the far North end of the Dalton after dropping a load of pipe or whatever, additives such as ethanol (which freezes at -114C) are added to the fuel in the tank to prevent it waxing.

    "Two NVIDIA Tegra processor modules are at the heart of the electronic components in the Model S, which "command a sizable price tag," according to Rassweiler. Here is a look at how they work."

    Um no... Nearly all of Tegra3's design wins (including 2012 Nexus 7) were due to it being cheap...

    Also, how is this news? It's been known for ages that the Tesla HU used Tegra3. http://www.theinquirer.net/inq... [theinquirer.net] (March 2013) - and I've seen documentation dating back as far as 2012 that Tesla was using the T3.

  • ... you're driving it wrong

  • The head unit has more than 5,000 discrete components...

    That's characteristic of small-volume production. If Tesla were making enough units, they'd have more custom ICs made to get the parts count down.

    • I'm currently designing a new product, and it's so integrated that it only has half an IC.

      And each solder joint is a failure waiting to happen in the vibration rich atmosphere of a car.

      I am not sure what the fascination over high component count. Does that mean all we have to do is make the next music player out of a million discrete 74xx IC and we will get a write up saying how good our product is?

      This to me is beyond a small product run. It is a prototype designed over a weekend.

      • Does that mean all we have to do is make the next music player out of a million discrete 74xx IC and we will get a write up saying how good our product is?

        You'll probably sell a ton to the bozos buying vinyl, tube amps, and expensive cables, because they think they're better.

    • I'd expect most of them are sensors for the various battery and motor things, or components to connect the sensors safely to the other electronics (opto-isolators, etc. to keep potentially high random voltages and currents from frying the whole system.) Once you've turned the analog data into bits, even with small-volume production it'd be fairly easy to use an FPGA or programmable microcontrollers to do the rest, rather than building lots of custom discrete parts.

    The auto makers are mostly work with very long life cycles. Vehicles typically get used for 10 to 15 years, especially for well built luxury vehicles. Model life cycles are long too. They are not used to the fast changing world of electronics and entertainment systems. My friend driving Mercedes hates its navigation system. He often uses google maps on his iphone. My BMW balks at playing old mp3 file created by ripping CDs in WinAmp back in 2000. Every other music player and computer will play those files, BMW alone will keep crashing its music file system and resetting itself. BMW's support of bluetooth is abysmal. My 2006 Prius links without any issue any cell phone via blue tooth. Have you seen how small BMW's approved list of cell phones is? The damned thing would not even support Nexus4 or Nexus5. And if I pair it with an "unapproved" model, somehow it forgets the supported models too. Theoretically it can maintain connections to four phones simultaneously and auto switch on incoming calls. But in practice it is extremely poorly done.

    Why wouldn't they just provide a simple docking station, allow the docked device access to the car speakers and stay away from building their own navigation and music players? They still think they can hold their customers up for ransom by demanding 1800$ for an integrated navigation system or 1200$ for the music player. No, just put in good speakers and allow us to bring our own devices into the car.

    The lack of imagination of the auto makers is astounding. WiFi is what 15 years old? iPod is 10 years old? Why didn't they build a car with WiFi that will connect to your home, down load daily news, weather, traffic reports into the hard disk 10 years ago? After missing the boat then, now they are coming up with walled gardens of WiFi, memory storage in the car etc.

    let me guess... the car doesn't run if you unplug the radio?

    I cant stand the way they integrate radios so far into a car now that you have no option to replace it should you want to. I don't care how good this system is, many people who buy the car wont want it. I should be able to swap it out for anything I want. When I replaced my fords "Microsoft Sync" radio a while back it killed my entire dash. I had to spend $200 on a translation computer to replace the bit of the radio that controlled the dash.

    Seriously, there's already an industry standard for car radios, screens, audio data, remote control, everything. Do us all a favor and follow industry standard.
