Willem Strijbosch, Head of Autonomous Driving, TomTom

TomTom, synonymous with satellite navigation systems, is making a big push into the autonomous vehicle area where it can leverage its mapping and UX expertise. At the 2018 CES in Las Vegas just-auto's Calum MacRae met with Willem Strijbosch, head of autonomous driving, TomTom to find out about their latest developments.

just-auto: So you've just announced a whole raft of developments in autonomous and what TomTom's going to be doing in the area. Can you take me through each of them and why they are game changing?

WS: There were six announcements, five of them were related autonomous driving. I'll try and recall all five! One of them was about AutoStream, which is a product to get high definition map data into the vehicle in a timely way and only the relevant data. Timeliness and relevance are key. Data needs to be up to date so that is as close to reality as it can be.

j-a: How do you ensure it is up to date?

We have several sources for our HD map database that we then stream with AutoStream

WS: We have several sources for our HD map database that we then stream with AutoStream, we have our own survey vehicles and we have sources coming in from cars on the road - crowd sourcing - that bit is small now but growing fast.

j-a: So anyone who's got a TomTom is contributing to the real time data that you have?

WS: Yes, but not necessarily a TomTom, because we need it from cameras and radars and LiDAR in the vehicles. That data's partially processed in the vehicles but we then process and we translate it into maps.

j-a: So you announced that you partnered with two companies for that, Baidu and Zenuity, are there going to be more partners and why those two first? 

WS: There will be more partners and we're first with Baidu and Zenuity because they are long-standing partners of ours. We pitched the concept of AutoStream to many OEMs and many other suppliers and there's a lot of positive reception for it. So undoubtedly there will be more.

j-a: And the other announcement was the driver sensing or the driver in the loop inputs wasn't it?

WS: Yes, MotionQ. It's a concept about problems that many people don't think about but that do exist. In this case motion sickness in self driving vehicles and how can you deal with that. And we have a long heritage of course in all sorts of user interface thinking in products. Some say that we already have three passengers in a vehicle having an autonomous experience that doesn't take into account that they may be facing backwards, standing up or they may be without a view out from windows.

MotionQ is a set of visual cues that enable passengers to anticipate an autonomous vehicle's motion, leading to a more comfortable experience

MotionQ is a set of visual cues that enable passengers to anticipate an autonomous vehicle's motion, leading to a more comfortable experience. It does this with intuitive overlays on the central display, communicating the vehicle's intended motion. It's here at CES in the Rinspeed Snap concept. The key is that we're exploring the concept, we're not really saying it's working we're just saying this is a problem, this is a concept that solves it to some extent, but it's one step in the direction.

j-a: How does the autonomous opportunity compare with your traditional business of embedded navigation systems?

WS: What we do in autonomous driving is provide an HD map service - MotionQ's a concept at this stage - including AutoStream and receiving all sorts of data from the vehicle. I'm not going to put any numbers on it, but analysts have for me and some of them are talking of a US$20 billion market. They're not my numbers, but we compare that to the market for standard navigation maps, which is about US$2 billion globally, and we're talking about a different sort of magnitude.

j-a: Do you think the need for good mapping is often disregarded in the race to autonomous because everyone tends to think it's about cameras, LiDAR and radar?

WS: That was probably the case a few years back. You'd have heard people say that humans drive with just our eyes, so we can make a computer do that as well. But that's a false analogy because we humans actually make maps in our heads. As soon as you have a commute with a car, as soon as you've driven it once you start to build a map in your head. You use point objects to localise yourself and if you for example take the exit of the highway to your home, there's multiple lanes at the bottom of the exit, it doesn't matter when it's raining, snowing, full of other cars, you know where you should put your vehicle, which lane you need to take because you've built that map. You're not reprocessing every time all the visual information. And that all translates to computing as well, it's very efficient and it leads to more safety and comfort in the vehicle if you have that map. 

j-a: How far do you think you can go with your mapping technology in autonomous, will there be a point when that's it and you can't do anymore development on it?

WS: Nothing is infinite but we are still developing our standard definition map technology and that's 20 years ago, we've done a major overhaul of our whole map making platform. We will continue to improve there.

j-a: What is next for TomTom in terms of autonomous capability?

WS: We will be adding additional partners, it's the phase that the industry's now getting into, the partnering has been going on for a long time, but it is now getting more and more concrete so there's a lot of suppliers like us really integrating with other automotive suppliers and a lot of discussions I have here at CES are about that. Then we'll start to see vehicles hit the road with those maps inside in about 2020-21 which is when most of the automotive manufacturers are asking for delivery. I think we'll then continue to make that maps richer, more features, refine the experience, all with the goal of making the drive safer and more comfortable.

j-a: What would you say your major competition for mapping is? Would it be HERE the BMW and Daimler joint venture? Why do they feel the need to have their own mapping technology?

WS: That's what you should ask them! I don't know what their exact motivation is, I just read what I read in the press, they were afraid that they would become dependent on Google, that's one of the arguments that they use in the press. They said Google would have bought HERE, or Apple or one of the other Silicon Valley guys.

j-a: So it seems to me there's much duplication of effort and if one of the drivers for autonomous is the elimination of road traffic accidents wouldn't it be better if everybody joined together and shared all the data? 

WS: I agree. 

j-a: Do you think that will happen in the future or are there too many commercial sensibilities?

WS: It won't be perfect but we are moving in that direction. I think that there will be more open standards, there will be more sharing.

j-a: Earlier on you said some of your information is crowd-sourced, so how many sources of information do you have on the road at the moment that are contributing to your mapping and how many do you see in five years time?

For change detection we already have more than 550 million devices contributing GPS information anonymously to us...we are so accurate picking up roadworks that the same governments that plan these roadworks come to us and ask "where do we have roadworks?"

WS: We have crowd sources and survey vehicles and at the moment survey vehicles are the main source, crowd sources is small but growing. Over time it will become a much larger part of the mix. You do crowd sourcing for two purposes, the minimum purpose is change detection. Which is super valuable. So you find where a crossing has become a roundabout for example. We only know that that has happened, the data that you have is not good enough to actually update the map, but now we know we can send a survey vehicle. For change detection we already have more than 550 million devices contributing GPS information anonymously to us. This information is even to the point that we can pick up roadworks and we are so accurate that governments come to us, the same governments that plan these roadworks, and they ask us, "where do we have roadworks?" I'm not kidding!

The number of devices we have reporting information will only grow as more and more cars get connected and some of those 550 million are smart phones used in a car, which is also still growing. The data we get is not limited to TomTom only devices. There are apps on mobile phones from which we get data, we have telematics units or a fleet management units - those guys contribute data. Some of the data we actually buy as there are competing telematics companies that also sell this data. It's a whole mix of sources.
