RF Safe-Stop Shuts Down Car Engines With Radio Pulse
An anonymous reader writes with news of a device built by a company in the U.K. which uses pulses of electromagnetic energy to disrupt the electronic systems of modern cars, causing them to shut down and cut the engine. Here's a description of how it works:
"At one end of a disused runway, E2V assembled a varied collection of second-hand cars and motorbikes in order to test the prototype against a range of vehicles. In demonstrations seen by the BBC a car drove towards the device at about 15mph (24km/h). As the vehicle entered the range of the RF Safe-stop, its dashboard warning lights and dials behaved erratically, the engine stopped and the car rolled gently to a halt. Digital audio and video recording devices in the vehicle were also affected.''It's a small radar transmitter,' said Andy Wood, product manager for the machine. 'The RF [radio frequency] is pulsed from the unit just as it would be in radar, it couples into the wiring in the car and that disrupts and confuses the electronics in the car causing the engine to stall.'"
those high-powered NSA satellites can do this from orbit. No, this is NOT meant to be a troll post. I wonder if a country could actually orbit a satellite with enough power and a spot beam to stop cars in an entire city... in the name of anti-terrorism, of course.

What could possibly go wrong!
This kind of thing would be ripe for abuse, but how many times have we heard/read about police chases which result in massive collateral damage and people getting killed?
I'm torn, but this seems like a really good thing for police to have. Especially if it can be directed so that it only affects the target.
So there are some potentially cool applications of this - stopping a criminal in a car chase with police, for example - but it has massive potential for crime as well. Stopping cars at night, in secluded areas, to steal them and/or assault the passengers? Or causing mayhem by stopping cars on freeways, not all of which will slow at the same speed, leading to massive pile-ups.

Pacemakers and implanted defibrilators monitor the function of the heart by detecting voltage gradients of milivolts. This weapon can reliably knock out electronics in a car - electronics designed to operate in a very harsh EMI environment due to the presence of the nearby igntion system and contained within the metal body of the car. An enclosure that provides a bit more protection than 5mm of glass and 70cm of flesh.
So when they say this device poses no risk to those with a pacemaker, consider me a bit skeptical of that claim.
In demonstrations seen by the BBC a car drove towards the device at about 15mph (24km/h). As the vehicle entered the range of the RF Safe-stop, its dashboard warning lights and dials behaved erratically, the engine stopped and the car rolled gently to a halt.
Let's try this demonstration again in a situation where you would actually need such a device, i.e. in a high-speed pursuit. A 15 mph demonstration means nothing for the safety of the product.
If it's for-profit but free, you're not the customer -- you're the product (e.g., the Slashdot Beta's "audience").
First thought: When shielding is criminal, only criminals will have shielding.
Second thought: This would be a really cool way to deactivate police cars that might be chasing you.

I thought this car EMP tech wasn't going anywhere when I started switching one of my cars to EFI late last year. Now this shit happens :-(
How can I shield my car against this? I'm willing to add up to 20lbs to do it.

Why is it that people name their product the very opposite of what it is? Is it supposed to serve as some sort of rebuttal? Safe for who? The guy going 60mph? Anyone around him when he loses power steering and brakes?
A car EMP cannon has been one of those things that tech workers have talked about for years. You could use it to screw up data centers as well...or maybe the bank's power substation. How about a pacemaker?
Digital audio and video recording devices in the vehicle were also affected.
So, they can shut off your camera before they beat you half to death?
Don't trust any concentration of power.
That it successfully disabled a few old dilapidated junk is no big deal. Those vehicles are just a skip, hop and a jump from junkyard and would fail more easily. A modern car well insulated against electromagnetic interference is likely to protect some systems and lose some other systems partially. This is just dangerous.

There was an article here on /. a few years ago about a hack by some geeks with a high powered RF generator in a van, and they trained it on some loud-stereo-playing cars behind them with excellent results. Anybody recall the details?
Does this destroy the electronics ie make them no longer work until replaced?
Does this affect other things like watches, phones, pace makers and other medical equipment?
Would be an interesting oops... wrong vehicle or a innocent vehicle is in range when this is triggered.

Well, number 2 shouldn't be an issue; if the engine losing power causes a wreck the driver was unsafe already. As for 3, no, brakes and steering are not, AFAIK, pure drive by wire although I'd be open to a citation otherwise. Given those, 4 is irrelevant; if an engine outage causes a person to wreck they shouldn't have been driving, and 5 is interesting and a little scary.

So the RF interference takes out the CAN bus, which runs communications between the various control units in the vehicle. This is a common problem in electrical vehicles, where the high power/current lines must be routed separately from the CAN bus wires.
There are two problems with this solution
1. Older vehicles are unaffected
Old cars, especially those with carburetors, are unaffected since they don't have any data buses that can pickup the interference.
2. The CAN bus carries safety critical information.
Corrupted data packets, such as by-wire throttle position information, can cause brake failures and/or uncontrolled acceleration when the ECU/TCU bombs out due to noise on the bus. Airbags may also deploy, although that is a bit more far-fetched.
A much simpler approach would be to sniff their smartphones, so you could send the driver a text that says "STOP UR CAR, LOL"
In my experience, the average driver will obey their smartphone screen more readily than local traffic laws.

Exactly. Why bother chasing when it's easier to trace them (a limpet GPS tracker works fine) and set up roadblocks?
-- Tigger warning: This post may contain tiggers! --
As an engineer, I've spent a lot of time chasing the noise gremlins out of systems. For a time, I've worked on high power pulse lasers (+1J/pulse, sounded like gunfire every time it pulsed) ..It was a challenge to keep the noise down in the ADC's, protecting the FPGA/microcontrollers, etc, but it was manageable with good ground plane design, proper shielding, zener diodes, inductor chokes, pi filters, twisted-pair lines, hard-line coax, EMI filters on AC power inputs , etc. We also tried hard for it not to be a strong EMI emitter; something that was a challenge for us. .I wonder what kind of measures they take in cars, and are there low-hanging fruit? I am unfamiliar with protecting electronics from an EMP pulse, but am curious about how other engineers would model and protect against this. Faraday shields don't offer 100% attenuation, induced voltage gradients, etc.
How do you get that limpet tracker attached to the vehicle?

Should be fairly easy for the energy levels involved here..
Shielded wiring harnesses in the engine compartment, generally around the low voltage components of the engine control module and a little bit of filtering on the power lines. Concentrate on where things come though the firewall because the engine compartment is usually a pretty good Faraday cage anyway.
Heck, you might just get away with putting some clamp on chokes on the few wires between the instrument cluster and the EMC and a small capacitor on the power supply near where they go though the firewall.

There are two types of people in the world: Those who crave closure
won't work if you drive a plastic car ['Vette, Saturn] but with metal bodywork your average care is already half way to being a Faraday cage. A concealed job of finishing that cage would be difficult but most openings just need a grounded hardware cloth covering of proper mesh [must study TFA to see what frequency is used].
Active jamming to cancel out the incoming waves is not likely due to the high frequency they probably use.
BTW, do they test this thing on Dick Cheney to see if it shuts down pacemakers?
SLASHDOT: news for people who can't concentrate on work or have no life at all and got tired of yelling back at the TV.
It would have been interested to read about them trying to rewire these things until they worked; simple measures like twisting conductor pairs, etc.
They start as stops for minor offenses, but the reason most people run isn't for minor offenses. There's a subtle difference. The cop sees a person run a stop sign, they go to stop them. Is the person fleeing cause they ran a stop sign? No, the person is fleeing because they have warrants, or drugs in the car, or guns, etc. The cop doesn't know this though, they're not psychic. So, to the public, "Why did you chase him? All he did was run a stop sign!" If it comes to the attention of the bad guys that when they run and drive recklessly, that the police will stop chasing them, this will make bad guys run MORE thus endangering MORE lives in the long run. There are consequences for everything. Very few people run just because of a traffic offense, there's usually a lot more behind them running. Stopping pursuits teaches the bad guys to run more often. BAD MOVE.
Basically, this device is causing the car's computer(s) to crash. So, during low speed tests, in a wide open area, the car slowly glides to a stop??? I wonder what might happen if this were applied on a narrow highway, with lots of other vehicles on the road, at highway speeds? And what will happens when this device is used by the disgruntled (postal) worker, or some teens (not picking on teens, I used to be one myself) out for a mischievous time?
What if occasionally the computer's crash in a less expected way -- say for a moment the computer thinks you're trying to "park" (using your computer controlled parking assistant) while traveling at 60 miles per hour?

Your car may lock its steering wheel when power is cut, but no car I've driven in a quarter-century does. I've had many occasions to key the motor off at speed (isolating engine and transmission when diagnosing problems) and steering continues working, though unassisted.
So long as the key is in the ACC or ON positions the wheel lock should not engage. Also, if you're in a manual or are quick enough with an automatic (and don't go to neutral first), putting the key back to ON will re-fire the engine.

Now if you want to test from the INSIDE of the 380, let me know so I can be sure to watch. I still don't expect much, but there *might* be an issue that way and I'd have the video camera rolling just on the outside chance I'd have some interesting footage to sell.

all that would need to happen is for the pacemaker to be in a faraday cage (metalized shell??) and it have a waveguide on the EXACT wavelength needed to "talk" with it (for settings stuff).
besides this would not be practical to have enough range to "pop" a number of cars at once (or a single car WAYYYY down the road).

sounds like you're essentially put in a microwave that uses a wider range of spectrum..... not only does your car stop (and likely have electrical problems forever), but you muscles come out medium rare.
You forget that most modern cars these days have literally dozens of microcontrollers and hang everything off the CAN-BUS (including the radio!). There are a lot of points of interconnection to worry about shielding/filtering.

Mission: To provide products that consume time and energy as entertainingly as permitted by the laws of thermodynamics.
For a motorcycle, the instrument cluster isn't really in your face, one of the nice things about the experience. No competent rider should have even the slightest issue with an engine shutdown in a motorcycle. That's just that. The most that would happen is in some very high performance models the variable steering damper might misbehave, but if you're riding in a way that you need that, you're already well outside the realm of legal operations. For the car, the steering will possibly get stiff and brakes less responsive, and as you say, there will be possibly some distractions. As long as it's less dangerous in sum than a protracted high speed chase, it's still a win.
Take the magnetron out of an old microwave and attach it to the rear bumper with a switch. In case the police are chasing me I turn it on to disable their car before they can pull in from of me to disable mine.

You'd have to faraday your entire car for this to work. Your entire wiring loom is one big antenna for this sort of signal. At the wavelength of radar, you'd be having a hard time keeping it all out too. Even tiny gaps to let the streering and drive shafts through, signal would probably creep in.
Making the electronic circuit boards themselves filter all their I/O and power lines for HF and over-voltage would be much easier to accomplish and probably more effective.

Depends on the frequency spectrum being used and the duty cycle, but you make a fair point. MRI machines use really strong magnetic fields. They are pretty safe things for human flesh because the frequency and duty cycles used does not heat up things that much. Microwave ovens and classical "radar" frequencies can and do present a danger though heating.
Personally, I'd be more worried about the nut aiming and firing the device getting some kind of dangerous exposure... But I suppose we can deal with that other ways.

This has been done before. I think at one time law enforcement were looking at launching rocket propelled trams from under a police cruiser, when deployed large metal prongs would pop up, when it rolled under a car in front of it, ideally the car the police were pursuing the engine would be fried and bring the car to a stop.

True, but you only really need to protect the Engine Management computer which in all the cars I own is under the hood to keep the engine running. Running from the cops really just involves keeping the engine running and the drive train in gear. All you need to do is filter everything at the firewall and close up the Faraday cage of the engine compartment. If you radio won't play the sound track for the dukes of hazard is really of no importance when running from the cops.

Remember when you could key your CB radio and watch those newfangled electronic injection cars down-throttle? I do. It was funny. This RF Pulse technology has no effect on cars with carburetors.
Pretty much every Japanese car has the ECU in a metal box under a metal plate in the passenger foot well. Some early Honda's had them in a box in the engine bay, but not any more.
You'd only need to shield the cables for the crank position sensors. All the other cables would either carry too much current to be adversely effected or abnormal signals would trigger an error code and at worse the check engine light would come on and the ECU would enter 'limp home' mode, with the engine still running. It may not run efficiently or at maximum performance though.
Have no experience with American or European cars though.

They are also not without flaws;
So back to StarChase, this "revolutionary" GPS launching system: It has some flaws. The cannon costs $5,000 and the non-reusable GPS "bullets" cost $500 each. During a recent media demonstration, four sticky bullets were fired at a car, but only one of them stayed stuck.
That was under good conditions. It is a good idea but not very practical.

Not if the transmission is still turning the engine and you have hydraulic power steering.
One of them fancy cars where you don't need to take the key out your pocket might have an electric steering lock though. Doubt they would be 'fail-secure' types. I would assume they require power to switch it to the locked position.

With a 164 foot range you would almost be standing on the wing to hit much in the Airbus. Just throw stuff instead. Probably not a good idea to do it 164 feet underneath it either just in case it works ;)
Does it even work from the side? How long does it need to be 'on' the target? The demo isn't clear but looks like directly in front. In which case it would get run over by whatever you wanted to stop. Unless of course they agree to do 15mph in front of safety barriers.
They do, you just need to move the car faster. The torque converter works both ways.
