The Self-Driving Vehicles Thread

Overlays from V2X could be added to ‘surround’ video displays like this:




FWIW I wondered about how easily vision-based systems could fail, but tech like this enhances it a tad.

Be interesting to see how it helps human-operated vehicles. Theres a data-processing limit to the OS with them

Yesterday evening watched one of the BBC's Crash Detectives programmes.

One fatal collision was where someone walked in front of an HGV at traffic lights. She timed it (shown by video recording) just as the lights went green.

Some form of detector on the vehicle, or additional warning, might have help prevent it.

I can't see how unless vehicles are expected to stop every time a ped walks up to a kerb, if that happens it will get abused regularly by people waiting to cross the road.
Depends if she walked in front of it after it started moving or if she was already in front of it.

Yup, that's why I said 'might'.

The HGV was stopped, in the rh lane, with a car in front. Pedestrian walked off the pavement, across lane 1 and in front of the hgv just as the green light went on. From the cab, just the top of her head was briefly in view, and hardly in view in the front mirror either. I cant remember exactly, but it was estimated that she was (I think) 0.9m in front.

A detector on the front might have applied the brakes.

All fine and dandy on super clean demo vehicles, but a day out on a road would see camera visibility down by half at least, and in the case of vehicles hauling quarry goods and or construction goods etc they'd be next to useless in five minutes flat.

Yes, yes, of course, put the cameras behind screens, give them heating elements, and wipers and water jets and air jets, that'd solve it right enough, but we'll need redundancies on those systems and the cameras.
It just introduces far to much complexity and potential for failure in the real world where joe blogs forgets to check his oil every week let alone his tyre pressures

Yes to all.

Presumably an AV would drive to the view available and flag any deterioration. But whether that would be enough to encourage someone to do anything about it is something else.

Of course, it might instead trundle (slowly) off to the local branch of AV QuikFit/Wash to get them cleared.

A mate has a BMW car with full 'surround' video coverage and the reversing system (video with 2x sets of lines and bleeps) also has a '3D' overlay.

Not too much of a stretch to expand it (in theory).

But attention on one thing is distraction from another.

If this is the one that gives a 'birdseye' view from above the car, I did some work with the developers. They'd had some low speed collisions during testing.

What i meant was that some drivers in a non-ADAS car can anticipate the chance of something coming out of nowhere (sic), but others can only cope with what is in view; adding another warning (what type?), which has to be perceived and processed and relates to the invisible may be too much.
Was it here on that someone mentioned a haptic jacket?

[Horse]

It was on some mega-expensive e-bike. When there's something in your blind spot it 'taps' you on the shoulder and then a voice in-helmet says "excuse me!" in the relevant ear.

[Horse]

Should AVs be equivalent to average drivers, or better? If better, how much better? How should this equivalence or superiority be assessed?

I'm glad you asked that, because it seems to me to be an important point to discuss.

But with the obvious 'what gets measured gets done' concerns.

It seemed likely that someone would have bothered.

Not what this research was for, but it hints at how that might be achieved.

Situation Awareness in Remote Operators of Autonomous Vehicles: Developing a Taxonomy of Situation Awareness in Video-Relays of Driving Scenes

‘ …we differentiated between “abstract risks,” which could be any conceivable event and “specific risks” which were named risks that directly related to the events unfolding in the video, as sub-themes within the over-arching theme of “Impending Hazards.”’


Of course, it ‘mirrors’ DVSA’s differentiation in the Hazard Perception Test where only ‘developing’ hazards are part of the scoring.

In good old blue book Roadcraft terms, "Anything which contains an element of actual or potential danger".

It's been said before, off-road development is way ahead.

There's only one way to sort this - fight!

Tesla in the news again for all the wrong reasons - Tesla Model 3: Paris' largest taxi firm suspends cars after fatal crash

Paris' largest taxi firm, G7, has suspended the use of Tesla Model 3 cars in its fleet, after one was involved in a fatal accident over the weekend.

One person was killed and another 20 injured, after a driver lost control of the vehicle.

Tesla has denied any technical problem with the car, which has self-driving features such as automatic steering.

Paris prosecutors have opened an investigation into charges of manslaughter and unintentional injury.

On Wednesday, France's Transport Minister Jean-Baptiste Djebbari also said there was no suggestion, at this stage, that the accident was linked to a technical problem.

Is the wrong reason that, it seems, the technology wasn't at fault?

"Car crash, someone died" doesn't usually make news of international interest.

"Car crash, someone died" doesn't usually make news of international interest.

It's unusual to get 20 people injured in a normal car accident, though I'm not quite sure how that number came from:

French media said the vehicle struck two pedestrians, a traffic light and a van.

[Lutin]

I think the critical bit was the "there is no suggestion, at this stage, that the accident was linked to a technical problem".

Hence the investigation.

There must have been some reason that one person is now dead and 20 were injured. Why would a car career into a crowd of people?

[Cousin Jack]

Having ridden in more than a few Paris taxis I can confirm that a fair number of drivers are intent on suicide and taking a few others with them. That was in normal cars, with zero pretensions to 'self driving'.

[Horse]

I think the critical bit was the "there is no suggestion, at this stage, that the accident was linked to a technical problem".

Hence the investigation.

So until that's concluded, it's a non-story.

Don't know about in France, but over here the driver would be cautioned at the scene, then the investigators would go over evidence to determine what happened, including technical problems.

Maybe something that is not a "non-story" - US safety body to probe Tesla on in-car gameplay

An investigation has been launched in the US into more than half a million Tesla cars that are equipped with touchscreens.

It follows a complaint filed by a user who discovered he could play games while driving.

The US National Highway Traffic Safety Administration (NHTSA) is looking into some 580,000 Tesla Models 3, S and X made from 2017 to the current day.

Tesla has not yet responded to the investigation.

The feature under scrutiny is called Passenger Play, and it allows users to play games on their in-car touchscreen.

It does warn that playing while in motion is "only for passengers" and asks for confirmation of this before allowing gameplay.

But the NHTSA noted that Passenger Play "may distract the driver and increase the risk of a crash".

It added that the feature had been available since December 2020. Previously the game feature was only enabled when the vehicle was in Park mode.

Distracted driving?

[slowsider]

Is GTA among the games?

Distracted driving?

My SEAT has a big touch screen with loads of options - including a photo gallery. Standard install.

Presumably that could provide a similar distraction?

Quite possibly. And the motor manufacturers would absolve themselves of any responsibility by saying that it says not do this or that in the manual. So if anything goes wrong, driving distracted for instance, then it's your fault. They could always decide not to fit such distractions in the first place, of course. But then they could possibly lose sales as their vehicle has less toys than their competitors' vehicles. Safety? Lip service is being paid to road safety by some motor manufacturers at the moment.
