Detroit, Ford, Tesla discussed on Leo Laporte - The Tech Guy


It's car guy time Sam Senate is here back from CAS where you saw were their cars at CSM. There were some cars here at in Las Vegas. You know, it's interesting over the last several years, you know, everybody started to think of CS is 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 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 CAS is kind of the technology. That's five or ten years down the road. You know, the 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 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 voice assistant, and none of them have hold a candle to any of the commercial echo or even Siri. Yeah. And that's that's a big part of why you know, everybody's trying to pull in these other systems integration. These other systems into cars because I think you've talked about this in the past where you know, one of the problems, we're trying to do voice control is 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 the cars. But that's what they're starting to do that. That's good. Yeah. The one of the a lot of the discussion I had this week with various companies was around kind of where they're going with computing in the vehicle, and so we we we've had chips in our cars since the nineteen seventies. This started when we started rolling out emission controls and fuel economy standards in the nineteen seventies. He started putting a lot of chips into cars and gradually grown. Most Neil modern cars today in have as many as seventy five to one hundred individual computers. Scattered around our. Yeah. 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 Hewer. 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. We call them electronic control units. Because back, you know, they're they're simple. Very simple. You we knows than a desktop PC. Yeah. Exactly. 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 is 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. Yeah. Absolutely. 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 its drive you into the into the garden. Yeah. That may be the case if your targets 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. I don't know. I don't know how how what does telematics is. It's like the onstar telematics is, you know, the the connectivity. That's been in the 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 where and then there's an entertainment media system, which is often a computer these days. Yeah. And then and that's separate from the telephone hopes that separated, and then there's there's separate units. But they're connected to they can talk to each other have a network in the car with all these things can talk to each other. 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 electric, stability control. If you starring starting to get there. So 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 Invidia already offers 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 where you need that's sophisticated computer. Yeah. That's part of it. 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 mean, 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 you're still going to have you know, small the speak computers. That are connected directly to. Sensors and the actually don't want a blue screen is stop you from stop definitely not. And I noticed this on the test. I can reset the entertainment unit. The big screen in them in the middle of the car, still drives, obviously that's a separate computer. Actually, 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 I'm rebooting one big, computer. 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 a 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 for for a lot of the small computers that are around the car. They don't even really have an operating system is such just have, you know, very simple scheduler that they're just runs a loop and goes through their dedicated chips their AC. Things things like your infotainment system. In many cases are running on June x blackberry or Lennox Lennox's, getting increasingly popular and a lotta these applications, and there's there's some other. Stuff from companies like when river, but you and accident Lennox are two of the big ones. That are that are powering a lot of this Microsoft. My old Ford sync, but Microsoft kinda got out of that business. Yeah. Most most of the companies Ford was the main one that was using windows windows, CE for sink and did some stuff as well. But they they moved to Q and apps, but just to give you an idea of kind of how things have progressed over the last ten years the first time I'd 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 on my first ride and Thomas vehicle that thing had big SUV. The back end was full of racks of computer servers. It had ten core. Two duo servers in. 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 above you know, roughly the size of a lap of typical laptop a thirteen inch laptop got four main ships 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. Sample submit. He's an analyst for navigate research,.
