IBM's Patent-Pending Traffic Lights Stop Car Engines

theodp writes "I'm sorry Dave, I'm afraid I can't let your engine idle. The USPTO has just published IBM's patent application for a 'System and Method for Controlling Vehicle Engine Running State at Busy Intersections for Increased Fuel Consumption Efficiency.' Here's how Big Blue explains the invention: 'The present disclosure is directed to a method for managing engines in response to a traffic signal. The method may comprise establishing communications with participating vehicles; responding to a stop status indicated by the traffic signal, further comprising: receiving a position data from each participating vehicles; determining a queue of participating vehicles stopped at the traffic signal; determining a remaining duration of the stop status; sending a stop-engine notification to the list of participating vehicles stopped at the traffic signal when the remaining duration is greater than a threshold of time; responding to a proceed status indicated by the traffic signal, further comprising: sending a start-engine notification to a first vehicle in the queue; calculating an optimal time for an engine of a second vehicle in the queue to start; and sending the start-engine notification to the second vehicle at the optimal time.' IBM notes that 'traffic signals may include, but are not limited to, traffic lights at intersections, railway crossing signals, or other devices for indicating correct moments to stop and to proceed.'"

      Hmmm, a computer at a railway crossing that can remotely disable a car's engine. To use the parlance of our times "What could possibly go wrong?"

      Besides the possibilities of "what could possibly go wrong?" the simple fact is, I am hoping IBM has done their research on this.

      Some car manufacturers claim that stopping and restarting the engine will use more gas, and cause increased wear on the starter. Others claim it will save as much as 10% in gas and not cause wear on the starter. I wonder where the truth really lies? Jeep recommends (for some of their vehicles) at least 1 minute of idle time expected before one turns off the engine to save gas. The government says (basically) "do it every time" - but the government also says that modern cars only need 20 seconds to warm up to a usable temperature in the winter. For those of you who have an actual temperature gauge in your car, you know that is not true... so I am not sure how accurate the rest of the government's data/speculation is (or quite simply, they did not test enough cars).

      That aside, there are other problems I have not seen mentioned, for instance dead batteries. If you are a city driver, and barely get over engine idle rpm during your drive, constantly stopping and restarting your engine can drain your battery. There are times I've had to drive in NYC and been on a two way main street going against the flow of traffic lights, meaning I've gotten stuck at a bunch of traffic lights during my trip. As anyone who has had engine (or lack of fuel) problems has noticed, if one repeatedly tries to start their engine, the battery will eventually get below "restart power levels" - meaning a bunch of people stuck at a traffic light without enough power to restart their engine. Add a cold winter day into the mix and this definitely should apply. As it is, I have experienced "uber cold" days on my visits to upstate New York where it sounded like if I had two or three attempts to start my engine, I would be lucky. Fortunately, my car only requires one. But driving a few hundred feet, shutting it off and trying again, then repeating that 5-10 times in under a mile would probably run me into problems as the car wouldnt have been running long enough at high enough RPM (1800?) to (a) recharge the battery enough for another start at those temperatures and/or (b) heat the battery enough for it to be able to deliver more starts.

      Also, unless starter technology has changed recently, the starter has a cool-down period between start attempts. Something mentioned in only a few car manuals simply because one starts the car, drives it, then shuts it off - usually exceeding the cooldown period. If you are needing to stop at a traffic light every city block, and restart your engine, then chances are, you aren't reaching the end of the cooldown cycle. The more the starter is turned on without reaching it, the hotter it gets. Anyone who has played with an electric motor knows what happens if they overheat.

      And as for the engine wear part of the equation, as anyone who knows a little physics can tell you, starting an engine does wear it more than normal driving... something to do with overcoming inertia (ie: the massive flywheel, and the internal inertia of the engine itself). Yes, above-normal driving (and to a much lesser extent, normal driving) still has similar factors to overcome, but there are other differences involved, namely that the flywheel is before the torque converter or clutch and the torque converter/clutch "absorbs" some of the "stand-still" force being overcome in driving/accelerating (ie: not as jarring to the engine - in comparison to "wrenching" a standing still flywheel into motion).

      And of course, all of the above could entirely be speculation... but that's not really the point that matters... the point that matters is, it's all based off one or more combinations of vehicle manufacturer information, various studies on the matter, and various real world applications of the situation (cold s

The US anyways seems to dislike the idea of letting people know about the green light ahead of time.
      • Cars where the battery is dead and need to be left running to get to the garage could wind up stopped with no power in the lane of traffic just before an intersection. Where if the light had not instructed them to turn off it would have been fine. To illustrate, I can ruun my 1994 car without a battery. The starter won't work, but if it gets jumped or I push start it runs just fine, but is a stick though.

As an alternative to IBM's patent, why make anyone stop at all, just keep their movements properly synchronized with the green lights.

      That was only possible during times of light traffic, when I could choose just the right speed. As I looked ahead, I could usually tell how about how long it would be before a light would change. If there was a crosswalk sign, what it said in the distance was also a clue. Surprisingly, very few other drivers seemed to be aware that there was a correct speed for staying with the synchronized lights. Most other drivers seemed to be traveling slightly above or below the correct speed. As the driver of a less powerful car with an almost worn out clutch and no air conditioning, I preferred to keep the car moving.

I imagined possibly having an electronic box on everyones dash which would make deeper or higher pitched beeps to tell the drivers whether to go faster or slower. Each traffic light could put out a weak radio signal giving information to the box in each car. That could be combined with either a range finding technique for distance to the next stop light, or possibly GPS.

      In recent decades, many more traffic lights have been added at entrances to shopping centers and elsewhere at incorrect distances from the next light that messes up the even synchronization.

      Traffic signals that inform the vehicle of the amount of time before the next green phase can make these systems more efficient since it will allow the vehicle to determine whether it is likely to be stationary for long enough to save fuel by stopping the engine.

      It would take more than enlarging certain items. The "over-sized starter motor" would have to provide enough power to turn the engine against its internal resistance, and keep the car going forward overcoming all the internal resistances of the parts, (with the car potentially dragging a trailer, or loaded to capacity, or both, while possibly moving into a headwind, uphill, or all of the above.) The real solution is not a half-measure like you've suggested, but just to go whole-hog hybrid. Or I guess that would be no-hog, or whatever. A starter motor is only designed to produce enough force to get the engine going against it's internal resistance, up to about the engine's idle speed. If you try to start moving the car under it's power, you have the additional internal friction of the transmission, the hubs, to say nothing of the aforementioned force needed to keep the car going. Then you have to use the starter to crank the engine (or whatever it's attached to) that much faster because of gearing. If you don't step it down, the starter motor will have to be vastly larger, (think approaching the size of the engine itself) to provide the torque at lower RPM's to move the vehicle. The added fuel consumption from having to make the car about 500 pounds heavier with all that extra starter motor, (to say nothing of extra battery) will negate the cost savings, and then some. If you go all the way to hybrid, then the advantage is realized because that vehicle is DESIGNED to do that, and the motor isn't attached to the engine in the same way, (AFAIK). In fact, I think a hybrid probably has a starter motor for the engine altogether separate from the motor which drives the wheels, which makes sense, that way the engine operates fully independently of forward speed, and the transmission doesn't need to be designed around the idea of having to also make it pull starter-motor duties.

The point of it was designing a system where cars communicated. With everything. And distributed computing calculated everything. I've since added traffic cams and GPS to that idea, such that every car would know where you were going, where every other car on the road was, would communicate (2-way) with every signal, camera, and car between home and your location (not always directly, as you could get an update of everything from just the nearest car with all the information) and then the GPS would inform the driver of the "best" route. "Best" could be lowest fuel use, shortest trip time, or whatever optimization they programmed.

    Of course, cars were all semi-automated as well, so that when you were in tight formation, the computer would take control and pilot it for decreased following distances and such. That would be possible because as the first in line braked for anything (like an emergency) all the other cars in the line would be notified and would also brake as well, so there's be no collisions.

    Improved traffic lights, which minimized delays (I never did find an algorithm I liked, but cost-oriented where time and fuel were both costs) would know everyone headed there and communicate their status to the cars so that cars could continue to cruise as approaching, or know to slow in response to the state the light will be there when they arrive. And cars would, as they do now, shut off when not in use.

    I guess the lights didn't specifically send a signal to turn on and off, but they sent a signal of when they were turning green and red, and the car decided on its own (through open and uniform rules, so every car operated the same) how to react, including shut-down when warranted. If they get something so simple and silly as that patented, I can see 90% of what I just said to be patented at some time.

Heck, it's still the same starter that came with the car in (February) 2000 when I bought it. Why did I stop using the technique? Gas got cheaper again and it is quite a lot of self-discipline if it's not done automatically for you. The times you turn it off and need to turn it on again after a second are especially frustrating. That said, on the routes you usually do, you get to know the lights and can usually anticipate when it makes sense to turn of the engine and when not. Fuel savings were real but with my car, really not in the "worth doing" it range. More like 0.2 l/100km, which translates (using 16000km per year, aka 10000 miles per year) to 32 litres saved per year.

      Also, be very careful with the phrase "A fuel efficiency increase of 5 MPG is a few hundred bucks a year" because MPG doesn't work as you think it works. There is a reason I used a 20 MPG to 25 MPG increase: MPG "increases" are not linear (and which is why most other countries work with "consumption" using litres/100km). Consider a 15MPG car that suddenly does 20MPG. That's accounts 666 gallons versus 500 gallons.... That "5 MPG increase" is much more significant that the one used in my illustration.

While there are lots of cars (as has been pointed out by many folks in the comments) that turn your car off when stopped, that's not what this patent is about. It would be nice if the Slashdot editors would read patents correctly before complaining. One could complain about this one but it would be nice to do so from a position of understanding.

    Here's the actual claim:

    1. A method for managing engines in response to a traffic signal, comprising:establishing communications with a plurality of participating vehicles;responding to a stop status indicated by the traffic signal, further comprising:receiving a position data from each participating vehicles;determining a queue comprising a list of participating vehicles stopped at the traffic signal;determining a remaining duration of the stop status;sending a stop-engine notification to the list of participating vehicles stopped at the traffic signal when the remaining duration is greater than a threshold of time;responding to a proceed status indicated by the traffic signal, further comprising:sending a start-engine notification to a first vehicle in the queue;calculating an optimal time for an engine of a second vehicle in the queue to start when the first vehicle starts moving; and sending the start-engine notification to the second vehicle in the queue at the optimal time.

    Note that you would not infringe this patent unless the traffic light sent out a signal saying how long before the light turned green and unless in addition that the other cars told you how many others were ahead of you in line so that you could figure out how long before you'd need to start. Certainly nothing does this now. We could debate how obvious the ideas are or perhaps find something in a Sci-fi book where this is done.

If a car is turned off (of course these are cars that opt in to this program) but it will not crank again it produces a traffic issue 2. If a car is turned off before it is stopped this produces a braking issue involving safety. Let me explain, most systems use manifold vacuum to be used with the braking system. Without the vacuum supply your have basically one shot at pressing the brakes and getting a good solid brake pedal, otherwise your manually trying to push the brakes which is virtually impossible to stop a car at speed. 3. At an intersection, there are 4 directions. What system will be used to ID which vehicles are going which way and which ones should be stopped? Perhaps the person in the straight lane has their turn signal to get into the left turn lane and is waiting for traffic to pass so they can move in but the light system has them stopped till the straight light goes again. 4. Hacking the system is always a threat. Remember OnStar early in its existence? Remember all the doors, windows, ect going haywire? Hmmm... Thats probably enough comment for now. It seems pretty much everyone is looking down on the idea. IBM was a little late announcing this, should have done it on April 1.

    I'm looking forward to when vehicles have collision avoidance systems in conjunction with mesh networking that avoid traffic stopping at lights altogether. It'll be a while, as we'll have to take the driver out of the loop.

    When it happens, it'll save a lot on fuel costs and speed up travel times.

    The transition will be difficult, as will pedestrians, cyclists and dogs.

    What kind of vehicle do you have? If your car is too small, or too motorcycly, or scootery, you may have to help the sensor pick you up by adding a magnet to the underside of your ride. Check the web, there are numerous sites that will give you the details. My solution to this, when the magnet trick doesn't work is twofold. One, if traffic is clear, go anyway. Hope not to get ticketed, (haven't yet). Two, avoid that intersection, and complain to the city, or whomever the authorities are who control that, because the sensors are supposed to work, if they don't, the sensitivity may be off, or the device may be malfunctioning. The people who live parasitically off your tax-money are SUPPOSED to fix it, so let them know it's not working, and they should take care of it for you.

    1) a remote signal that can disable your car's engine? I can thing of dozens of ways this could be used to cause fatalities. it going to be really easy to hack...
    2) This can't be used to prevent cars from going through intersections, it would only work for cars already stopped, so this is a lot of technology and risk to only save gas, not lives.
    3) if the car is stopped, it can simply cut off it's own engine, and when you press on the gas, start it again. The Prius already does this, and most regular cars can be augmented with a $100-200 kit to do it as well. The only drawback to adding it is other vehicle electronics are effected every time the engine turns over, but on brand new cars being made, this is a simple system to implement, easy to accomodate, and if it has no external control access, it can't be hacked easily (requires physical access) either.

    Even without climate control, in 110 degrees and low humidity, your sweat acts like a cooling mechanism, as in you sweat a little, it evaporates cooling you off. This evolutionary advantage is completely fucked by humidity. Sweat does not cool you off, in fact there is no natural way to cool off, even as I mentioned, waiting until dark barely nets any benefit.
