Detroit, Tesla, Ford discussed on Leo Laporte


It's car guy time Sam apple Senate is here back from CAS where you saw with their cars at CSM there. There were some cars here at in Las Vegas. See, you know, it's interesting over the last several years, you know, everybody started to thank C S as a car shell. But it's it's different from any other of the traditional auto shows like the Detroit auto show that kicks off by the evening and an ended tomorrow where it's not a place where carmakers usually go to introduce new new products. They got the Detroit auto show for that. They don't need. Yeah. And you know, what you know, what we usually see at CBS is kind of the technology. That's five or ten years down the road stuff autonomous vehicles connected vehicles. And even even some stuff that's coming a little bit sooner, you know, one of the big topics. This week was a lot of discussion of integrating voice assistance into cars had talks with several different companies including Amazon about how they're integrating. Alexa auto into cars IBM. Of course, Google, you know, bringing assistant and cars, they pulled it into Google maps. So, you know, there was a lot of that kind of discussion. But I remember four with Ford sync had their own voice assistant. My ATI has its own voice assistant, tesla has its own voices. It's and none of them hold a candle to any of the commercial echo or even Siri. Yeah. That's that's a big part of why everybody's trying to pull in these other systems integrate these other systems into cars because you've talked about this in the past where you know, one of the problems, we're trying to do voice control is, you know, it takes a lot of computing power to do that. And so it was it's it's been hard hard to do that. Consistently especially in the automotive. Environ? Course, they don't wanna put expensive commanders in their cars. But that's what they're starting to do. I'm going to do that. That's good. Yeah. The one of the a lot of the discussion I had this week with various company was around kind of where they're going with computing individual. And so we we've had chips in our cars since the nineteen seventies. They started when we started rolling out emission control and fuel economy standards in the nineteen seventies. He started putting a lot of chips into cars, and it's gradually grown most meal. Modern cars today can have as many as seventy five to one hundred individual computers. Scattered around our controlling everything from your radio to your your fuel injection system to your steering. There's even a body computer that you know, when you press the power window switch that makes the power windows, go up and down or to control the seats and things like that. So there's a lot of these little tiny. Computers around there. What we're starting to see now is a trend towards fewer. More powerful computers because all of those computers over the last thirty forty years, it'd been kind of added on piecemeal as we added a new function we brought in a new computer for you would call them electron of control unit because they're simple simple. We knows than a desktop PC. Yeah. Exactly. In fact, many cases, not even that power. Yeah. So this is an interesting issue though. Because the the advantage of having all those separate computers is your car, it's harder to hack your car. But with a centralized computer system, controlling the whole car somebody were to get into it. Your car would be vulnerable. You would be vulnerable. Yep. -solutely, and you know, I mean, this is one of the issues with going to connected and automated vehicles is that the whole security issue, if your your phone gets hacked, you might lose information. It's drive you into the into the guardrail. Yeah. You know, that may be the case if your car gets hack, so I think of the car computers, besides the things like the fuel injection controllers as being the telematics stuff, which is kind of the I don't know how how what does telematics is like the onstar telematics is, you know, the the connectivity. That's been in. That's in cars, and it's getting increasingly common. So that's the having a cellular data modem in your car that can communicate with the data center San sandwich. And then there's an entertainment media system, which is often a computer these days. Yeah. And then that's separate from the in hopes that separated their separate units. But they're connected to they can talk to each other. You know, you have a network in the car all these things can talk to each. And then is there a third like computer for controlling the car itself the engine and so forth? Yeah. So you have a powertrain computer that controls the engine. And the transmission you've got computers for your electronics stability control. If you starting starting to get there. These are all separate controllers. Are they eventually going to merge into a single controller or? Yeah. That's that's definitely the direction that people are going in fact, Invidia and Mercedes-Benz made an announcement on Tuesday that they are going to be developing a power essentially a supercomputer for the car. I mean in video already offers up a supercomputer platform for automated driving systems, they call. I guess that's what I'm wondering is this being driven by the move to a Thomas vehicles. Were you need that's sophisticated? Yeah. That's part of it. And part of it is because we have all these other things, and you know, they're just trying to consolidate them all and provide make it easier to do things like over the air updates and in one of the advantages. Tesla had you know, part of the reason why they were able to do over the air updates when they launched the model S is because they were starting from scratch. They didn't have any legacy computers in the car. So they just built a central computer to begin with. And so they have this the centralized system, and that's the direction that the whole industry is going to be moving towards in the next few years, although we're still going to have some some computers at the edge of the vehicle is well for some of the the the emergency assistance systems since like automatic emergency breaking now, you're still going to have, you know, small this week computers that are enacted directly to the actually don't want a blue screen is stop you from stopping now. Definitely not. And I noticed this on the test like can reset the entertainment unit. The big screen in them in the middle of the car, still drives, obviously that's a separate computer. Naturally. I think it, you know, what the what's happening is as we go to these centralized systems. We're going to you know, to hyper visor, so you're getting virtual, Michelle. I'm rebooting one. Big computer? But it's running a bunch of virtual machines on hyper visor that manages all that. So you can reset your your infotainment system without shutting down the whole car. That makes sense says the virtual machine, and it's rebooting. Wow. I didn't realize that what operating system our cars using. Are they using windows MacIntosh? What do they do? No. I mean, if for a lot of the small computers that are around the car, they don't even really have an operating system is such. I just have you know, very simple scheduler that they're just runs a loop. And and goes through their dedicated chips there Acer. Things things like your infotainment system. In many cases, are running on q and x from blackberry or Lennox Lennox is getting increasingly popular in a lot of these applications, and there's there's some other stuff from companies like when river, but you and apps and Lennox are two of the the big ones. That are that are powering a lot of this Democrats ran my old Ford sync, but Microsoft kinda got outta that business. Yeah. Most most of the companies Ford was the main one that was using windows windows, CE for sink and Fiat did some stuff as well. But they moved to Q and apps, but just to give you an idea of how things have progressed over the last ten years the first time I like to see us was in two thousand eight and I got a ride in the Chevy Tahoe. That won the DARPA urban challenge. I was my first ride in autonomous vehicle that thing had big SUV. The back end was full of racks of computer servers. It had ten core. Two duo servers in there. Combined combined computing power of about one point eight billion instructions per second. Okay. And the the Invidia Pegasus system that they're selling. Now, there's they're sending shipping samples to their customers. Now is a single board. That's about you know, roughly the size of a lap of a typical laptop like a thirteen inch laptop got four main chips on there. It does three hundred and twenty trillion per second. Wow. Just like everything else. Cars are getting smarter and SAM's gonna cover it for us. He's our new car guy Samuelson, and he's an analyst for navigate research,.
