Nissan Exhibits IEEE 1394-Compatible Car

Posted by ryuzaki0 on from the no-usb2 dept.

Dirak writes "High-speed IEEE 1394 optical fiber networks have gone off-road with new Nissan's prototype vehicle demonstrated this year's at 11th World Congress on Intelligent Transport Systems. The prototype is equipped with 7 cameras on the body and a 12-inch LCD monitor in the front and another in the rear seat area. Thanks to the in-vehicle IEEE 1394 LAN, which is capable of high-speed communications at 400Mbps via optical cable, the front and the rear seat monitors can display various information simultaneously, for example. The application of optical fiber also means that the weight of the cables can be reduced to about one-half the weight of a conventional wiring harness."

    Wow, they're bragging up the reduction of weight of a wiring harness in a car. That's just awesome. Holy crap don't want to go over GVWR in the Nissan with a copper cabling system. Pardon me while I go shopping for light weight optical camping gear as not to kill my gas milage.

      Actually......the typical weight of an automotive wiring harness is around 50 lbs which absolutely does impact your milage and has been an issue for automotive manufacturers for a number of years particularly with increasing fuel economy standards that will be going in place over the next few years. Every little bit helps.

      Actually, wiring harnesses are pretty damn heavy.
      I know that a wiring harness of a Cadillac Escalade weighs in at somewhere around 100-110lbs for the complete harness.

      Reducing weight is a big deal for automakers.

      That's not right. Let's try it with some example numbers. Say we get 20mpg. Over 150000 miles with $2 gas that's 150000/20*2=$15000 in gas. Now we get 0.5 extra mpg, so it becomes 150000/20.5*2=$14634. I think you calculated the cost of running a car that gets 0.5mpg. You can't even pin that on an H1. :P

    The last time I checked optical cabling like niether virbration or dirt. So is this really a great application? BTW 1394... WHY? it makes some sense but seems slightly random as well.

    FirewWire is trademarked by Apple.

    And Apple licensed it to the 1394 Trade Association in May 2002:
