Autonomous Vehicles

Except Tesla's are equipped with radar, and lidar is not a solve all solution like you and many others thing, it is poor at seeing through weather.

Yea I never thought of LIDAR as the best solution for this really. Also with loads of LIDAR devices in the area, surely they will interfere with each other? Even on attack helicopters they will normally only have one running in a group of them. TBH the current AVs seem like something which has been bodged together to go "hey look it works", but actually no it doesn't.

Opinions and sentiment running strong here because we all have opinions that will eventually be borne out or discredited by facts that can be substantively proved. Until there is an active, large-scale commercial deployment of self driving vehicles, we will probably continue to see a huge disparity of opinions. At the moment there are many promises of this deployment (GM in Miami in 2019, Waymo in Phoenix later this year, etc). The Uber crash has set back the clock for some players: Uber, Toyota, Nvidia, etc. Yet it is worth noting that Waymo has just invested $ 1 billion in the Jaguar I-Pace because it believes in its current technology and its roadmap.

Nasher says: "TBH the current AVs seem like something which has been bodged together to go "hey look it works", but actually no it doesn't."

I respect that is your opinion. It certainly is not mine. I remind you that Waymo, for example, has been conducting testing of AVs since 2009, has tested many form factors---SUVs, trucks, Firefly, MiniVans, sedans--- and have "driven" in autonomous mode more than 5 million miles on public roads with more than 5,000 miles between safety disengagements (ie human driver takes over for autonomous "driver"). They have shown, in my opinion, that, to use your phrase, it actually works.

They have a strategic plan for a commercial deployment this year. They appear well on track as they became the first to deploy a self driving vehicle on public roads without a safety driver in the front seat. Time will tell about success or otherwise but it would be unfair to say that their strategic plan, developed over 9 years, has been "bodged together to go hey look it works." Three years ago they determined that in their "driver solution" they never want a human driver behind the wheel---ever! No semi-autonomous (ie Tesla type) interim step. Waymo has pointed to a 2015 regulatory study that found some drivers took 17 seconds to retake control of a vehicle, a duration that would have allowed the car to travel more than a quarter mile at highway speeds.

Waymo has announced a number of partnerships for their commercial deployment. They are working with two important automobile manufacturers (Fiat Chrysler and Jaguar Land Rover), they have partnerships with Lyft (2nd largest ride hailing firm in US), Avis (for servicing their AVs to get them to be able to driver 250,000 miles on public roads), and with AutoNation for parts and equipment.

And according to Bloomberg today, they are close to announcing a major deal with a third auto maker, Honda, which unlike the partnerships with Fiat Chrysler and Jaguar, will have two new characteristics:

1. They expect Waymo and Honda to build their self driving vehicle from scratch and not use an existing vehicle as their prototype.
2. The focus of this Honda vehicle will be on delivery rather than ride hailing.

Interesting times.

According to Tesla this morning, the driver of the crashed Model X had Autopilot turned on. This crash, coming 5 days after the fatal Uber crash has some same but many different characteristics to the Uber crash. For one, the X uses Autopilot, a Level 2 feature which is really a glorified ADAS system....assistance to the driver, while the Uber car was an autonomous vehicle that apparently failed. Yet it seemed the driver of the Tesla used his vehicle like a robocar, according to this interpretation.

The Tesla article does not seem to dsicuss whether the radar should have been able to distinguish the (dense) concrete obstruction, or was it's profile too small ?

There was another earlier incident surprisingly not referenced in that link, radar had not spotted it too ?

As you suggest, there is more to be revealed about this fatal crash.

Meanwhile, the NTSB has issued a rare public rebuke to Tesla as it is customary for facts to be released first by the NTSB investigation.

Interesting video showing mobileye(intel) technology behind tesla/nvidia(google too?) image processing systems, from 2015 but it takes a while to migrate into cars.

had not seen the obstruction/pothole/yak identification technologies before, and discusses the need for hd maps that may have enabled tesla to be aware of concrete obstructions.

....intel inside ...
 
Teslas do seem to have a thing about not seeing trucks. Didn't one go straight in to a stationary fire engine last month?

I believe you are referring to this, as referenced in Bloomberg: Joshua Brown died in May, 2016 when his Tesla Model S struck a truck crossing the road in front of him on a Florida highway. His car showed no signs that he tried to brake or evade the truck, which was making a left turn, as he drove at 74 miles an hour. Investigators concluded the car was driving itself.

Interesting video. It is of course hypothetical to ask and answer your question about what might have been for Tesla with regards to last week's fatal crash.

You may know that Tesla and Mobileye had a very public fall-out between themselves and Tesla no longer includes Mobileye in future Tesla Autopilot versions.

you could have posted the explanation - because the fire truck was obscured - lol ?

As the online forum community continued to debate about the benefits and risks of Tesla’s Autopilot software, a member of the r/TeslaMotors subreddit who claimed to know the driver of the crashed Model S spoke up and provided some details about the accident. According to the Redditor, the Model S was traveling behind a pickup truck with Autopilot engaged. Due to the truck’s size, the Tesla’s driver was unable to see beyond the vehicle in front.
....
#“The driver of the Tesla is my dad’s friend. He said that he was behind a pickup truck with AP engaged. The pickup truck suddenly swerved into the right lane because of the firetruck parked ahead. Because the pickup truck was too high to see over, he didn’t have enough time to react.” notes mikhpat

lucky (for him) the crumple zones on the car are good.

presumably the mercedes sytem would not have reacted fast enough to steer around the obstruction either Mercedes's autonomous driving on highway - YouTube
had seen a video (which cannot refind -anyone else seen it ?) where car was 'detecting' motion of car 2 ahead and braked with that.

could not see the word mobileye in the article. ?

The intel eyex processor, as early video explianed is very advanced/powerful/efficient - I don't believe google have the dvelopement teams and fab access to beat it ?
 
This one isn't really that relevant. None of the current driver assistance systems/emergency breaking systems in use on the market can't deal with this situation yet.

A pair of eyes and a right foot can though :D

Problem is people turn these systems on and sit back. Then they don't see this coming.

Remember depending on year there's three different AP hardware
Ap1 is mobileeye
Ap2 and ap2.5 are Teslas own and very similar.
Also depending when all these crashes happen, you have major software changes.
So you can't just throw up old ones and say look at this.

That Tesla AP distinction you cite is also my recollection.

While we are in the Autonomous Vehicle thread on Overclockers, it is tempting to lump all efforts (Waymo, Tesla, Uber, GM, Audi, BMW, Ford, etc) in this field with the same broad brush: to seek full autonomy in a series of steps. That would be a mistake as Waymo's CEO has said in this Bloomberg link recently. The Tesla approach with AP 1, 2 and 2.5 are essentially driver-assist technologies, not self-driving technologies comparable to Waymo. OEM's, reluctant to see their car sales drop off a cliff, speak on behalf of assisting the human driver to make better decisions.

As previously discussed, Waymo concluded three years ago that there is no role for mixing a human driver with its self-driving technologies because the human will over time get complacent and reduce reaction times. They have urged for their "full autonomy-or-else approach" for years.

The mobileeye video shows an incremental development of hardware capability to get from driver assistance to full automation,case in point being lane identification functionality, needed for both, and relevant to the silicon valley barrier crash.
Seems to be a hypothesis that the tesla
AP1 hardware solution may have handled it better
AP2 hardware solution (he needs to re-run in the dark)
 
That's pretty damning.


This is from the same guy. Wonder what's changed between those trips and this time.
Someone posted a similar example elsewhere few days ago. My first time seeing this edge case in maybe 20k miles of autopilot driving on this exact road.

It seems like it the white line on the left that is causing it to swerve to the left. Not sure how it works, but i'm assuming its using the lines to figure out what direction the road is going in.
