A lot of modern cars come with advanced driver assistance systems,

things like adaptive cruise control that keeps a safe distance from the car in front

or automated emergency braking to avoid collisions

Which is great, as long as the driver knows the system's limits.

The worst modern car I've ever driven came with

adaptive cruise control that turned itself off

So if the car in front slowed down for a traffic jam, so would you,

at which point the car just handed control off to you

and, as of this year, it is part of the EuroNCAP standard

on how to test the safety of automated driving systems.

This base here is a robot platform that goes up to 50mph,

which means you can test safely with both vehicles going at highway speed.

- Thatcham Research is a not-for-profit insurance-funded research centre.

In about 2014, it became clear that the next generation of technologies

weren't just going to look for the rear end of the car,

they were going to look at the side of the car

We've got to have a target that actually looks like a three-dimensional car.

The impactable bit, the visual pieces of the car,

are actually foam target blocks which are assembled to look like a car

Generally, you can put the target, from start,

And what we've done is we've used test equipment

that actually measures the radar reflectivity of a real vehicle.

So you get radar reflectivity of a wheel.

And even the glass, the back of the vehicle, has a certain radar signature.

and also radar-absorbent material in the right place.

So the brand-new tests that we're going to introduce in 2020

where your vehicle is moving in front of another vehicle

where a vehicle moves across your path laterally

and therefore we need to see the side of the vehicle.

And we're confident that if a vehicle brakes for our target,

it'll brake for a real vehicle in the real world.

- Radars are very good at understanding if something is moving.

However, if you just come across an object and it's stationary,

it's much harder for the radar to identify that that's a vehicle.

What's the difficulty is understanding: has the driver seen it?

So if you've got a vehicle that's parked in front of you,

because that's gonna annoy the driver and we don't want that,

One of the problems vehicle manufacturers have is

there are not only differences in the road infrastructure,

but there's actually national characteristics.

People in Germany tend to drive slightly more aggressively.

And, therefore, the issue of false positives,

Whereas the Swedes will tell that they're much more benign

and, therefore, a vehicle that's just stationary,

warning the driver won't really annoy him too much.

- OK, so what happens if we go slightly faster?

- Well, we'll try it, and it should be, you know...

- You hope, with that little brake, it's enough for the driver to go,

oh, this is... something strange is happening,

- Thank you very much to all the team at Thatcham Research.
