Lidar is the technology that’s going to unlock eyes-off, hands-free driving.
In Europe, the company at the forefront of development is Israel's Innoviz, which supplies BMW to enable level-three self-driving in the 7 Series and will also drive similar level-three set-ups in Porsche and Audi.
'Lidar' is an acronym for 'light detection and ranging'. Essentially a 3D camera, it fires lasers ahead of it to create a ‘point cloud’ that helps the car understand the relationship between objects around it.
European cars have so far used the technology sparingly, if at all, but Chinese car makers love it, even though they’ve not gone beyond level-two (eyes on) assisted driving. That’s despite the fact the technology is also expensive and tricky to master.
Innoviz co-founder and CEO Omer Keilaf is very confident indeed that his technology is going to drive the autonomous revolution. He’s also very open about the competition, why level three is actually harder than level four (driverless) urban autonomy and how China both represents the biggest threat and actually doesn't worry him at all.
We spoke to him at the recent CES tech event in Las Vegas...
Omer Keilaf on why L3 is tougher than L4
"People expect me to say that the level -four lidar should have better resolution and range because there’s no driver, but that’s actually not the case. The requirements are higher for level three, because of the speed on the highway. You need to see that small object 200 meters away, because you're driving so fast and you need to react.
"Level four is for urban situations and is much slower. The real difference between levels three and four is the lack of driver. You need the lidar to be super resilient to anything that might happen. And if the car goes into a puddle, then you need to stop to apply the cleaning system. This is the worst situation: where the car needs to stop and everyone in the car has a problem."
On unscrupulous lidar companies
"When companies design a lidar and don't take into account real life, you won't see the problem in a five-minute demo, because lidar companies know where to drive to avoid seeing this problem. There are dirty secrets – like really dirty."
On level-three programmes that failed
"Several level-three programmes failed because the OEM didn't know really enough about how complicated lidar is.
"One OEM after two years discovered that the lidar they were using was so strong that it actually burned cameras in the streets; take a picture of the car and the image sensor on your iPhone will be burned."
On the cost issue
"How much was Tesla’s Full Self Driving [system] priced at? $15,000? $100 a month? What would be a relevant price point for a level-three system for the customer? I would argue that the $500 lidar is not the problem.
