Ford's New Car Tech Prevents You From Accidentally Speeding 287

An anonymous reader sends word of Ford's new "Intelligent Speed Limiter" technology, which they say will prevent drivers from unintentionally exceeding the speed limit. When the system is activated (voluntarily) by the driver, it asks for a current maximum speed. From then on, a camera mounted on the windshield will scan the road ahead for speed signs, and automatically adjust the maximum speed to match them. The system can also pull speed limit data from navigation systems. When the system detects the car exceeding the speed limit, it won't automatically apply the brakes — rather, it will deliver less fuel to the engine until the vehicle's speed drops below the limit. If the speed still doesn't drop, a warning noise will sound. The driver can override the speed limit by pressing "firmly" on the accelerator. The technology is being launched in Europe with the Ford S-MAX.

    My GPS already does a great job at noticing I'm speeding and warning me, even in the rain with poor lighting. The interface to a fuel cutoff would not be that hard.

    I think Ford should invest in getting everyone a moving map GPS rather than letting pranksters plant signs that mess with their vehicles, which will speed at night in the rain slightly more often than I would, were I to care.

    So, bad tech, toward a bad goal. Go Ford!

      There's also temporary limits imposed by road works.

        sometimes i'll look down and see i'm going 85, without noticing or thinking about it

The only thing that separates the two is a bit of chain link fence and about 10 feet of grass. Guess what those frontage roads have? Yep, speed signs. Guess what a car I test drove picked up on as the speed limit for the freeway? Yep, the speed on the frontage road.

        This is a terribly thought out idea. I'd rather trust a GPS map that has the speedlimits assigned to it.

      That will happen soon. The big cost of GPS navigation is not the receiver, but the display. But displays will be in all new cars starting in 2018, because backup cameras will be mandatory. So sticking in a GPS is a minimal cost. For many current cars, the backup camera and GPS are part of the same package. You get both or you get neither.

      My Ford has a speed limit database set up as part of the Nav data for the GPS. However, it is apparently set with a maximum permissible speed limit of 74 mph. That means that it is artificially low for most of the Interstate highways in the west. Most western states have a limit of 75 on the open road -- some have stretches of 80.

      Pranksters planting signs? Hmm... how many times have I actually seen this in my entire lifetime? Oh yeah... zero. Let's see... how easy would it be to simply put a logical limiter so it doesn't ever read 170mpg instead of 70mph? Trivial.

      This technology is simply an incremental step to a completely autonomous car, in case you didn't figure that out. You're going to see more and more incremental steps like this as we move along the path first to partially autonomous and finally fully autonomous vehicles

      • Meanwhile here in AU, it's quite common to see dual-sided speed signs. The "front" has the normal road speed (which might be 110km/h - around 70mph). The "back" has a roadworks speed limit of 40km/h (25mph). Watch for shenanigans as the Ford sees the wrong sign on the wrong side of the road (not uncommon either) and suddenly decides the road is 1/3 of the normal speed.

          Meanwhile here in AU, this technology is already available and works perfectly works fine as is. I have it in my own car. Both Mercedes and Audi offer speed sign recognition that feeds in to the adaptive cruise control. Mercedes have been offering it for over 5 years now. If it ever did recognise the wrong sign, you can easily override it, either via the pressing the brake, the accelerator or manually adjusting the limit from a control on the steering wheel.

    I've driven a car with a manual speed limiter for 10+ years now. I don't understand why all cars don't have one. Entering a 30mph/50kmh zone? Set that as the maximum speed on the limiter and you can drive around normally without having to keep checking your speed. Less time checking your speed equals more time looking where you are going. This is only a good thing.

    In Europe, speed limiters seem to be common in Mercedes and Smart cars, Renault, Citroen and Peugeot cars, plus some of the newer Vauxhall/Opel models and Fords. It is built into the cruise control system.

    The bad points? Well, reading signs is a so-so thing when it comes to accuracy, and satellite navigation systems sometimes get the speed very badly wrong if they have incorrect data. And just because the speed limit *says* that you can drive at up to whatever-is-on-the-sign, it doesn't mean it is *safe* to do so in the road conditions you actually have.

      While I appreciate your point of view I also think that having drivers maintain some sembelance of situational awareness is worthwhile. I can fairly accurately guage my speed and inly occasionally need to look at the speedometer to validate my assessment. However, as drivers turn over more functions to automation they become less aware of what is happening around them as the come to rely on the automation to take care of things. As a result when things go wrong they may not realize it in time to take effective corrective action. In essence, automation can lull them into a sense that all is well when in reality it is not. Automation should assist, not replace, human actions.
      • I agree with you in general, but I think it's fairly easy to leadfoot it *unintentionally* and go fast, especially on big open freeways.

        Actually, it seems easier in my electric car (smart electric, one of the wimpiest ones), because I'd at least notice the higher revving of the engine in a gas car, even in a high gear.

      How long does it take you people to check your speedo, for me it's a fraction of a second. This is for every car I've ever been in.

      Also, if you spend all your time with your eyes glued to the road in front of you, you're driving horribly wrong. You should be focusing on multiple things, mirrors, instruments, blindspots. If you're not checking your mirrors every 10-15 seconds you're danger

      I completely disagree. If there is roadway traffic, you don't need to check your speedometer as the safest and smoothest thing to do is to simply travel with the traffic. If you drive much faster than the bulk traffic flow, you risk causing an accident. If you drive much slower than the traffic, you risk getting rear-ended or clipped as irritated drivers people pass you. You also substantially disrupt traffic flow and actually slow down everyone's commute.

  • Once in a while a sign gets overpainted a little by someone: 35 changed to 85. What does the vehicle do then?

      • And it is likely that such a sign is on a highway where the speed was 55 but drops for a mile or less for a speed trap. What good is making sure that the car doesn't go faster than 85 when it is already 20 over the real speed limit?

          GP's point is that this system sets a maximum speed, not a minimum, not an average. So it is not going to go 85, or even 55, unless you push the accelerator and make it happen.

        Pretty soon folks will get used to tuning out while driving (more than they already dangerously do), and when there is a crash it will be reasonable to argue that the automation was to blame.

        We are rapidly turning drivers into only being partially in command. Some of the recent plane crashes caused by pilots with atrophied skills being faced with bad conditions and an autopilot that throws its hands up should be cautionary tales against this semi-automation.

        • by dasunt ( 249686 )

          We've already tuned out. Try riding a bicycle or motorcycle - as a non-typical vehicle on the road, more drivers won't notice you and you'll have more close calls.

          We just aren't wired to be diligent over the many hours we drive in our lifetime. We get used to things. We run on our own autopilot already. And that can end up being deadly.

    • Somebody who can't pay attention to the street signs shouldn't be driving.

      No, they shouldn't, but some of them are going to anyway. Since your loved ones will therefore be just as injured/dead if they are the unlucky ones who get hit by a bad driver who was going too fast, dismissing technology that might help those bad drivers to be better, safer drivers seems uncalled for.

    • I have cruise control, thanks. Somebody who can't pay attention to the street signs shouldn't be driving.

      Anyone who thinks cruise control is the solution to prevent speeding in non-highway situations (where the speed limit is 35-45mph, and there are traffic lights every half mile) shouldn't be driving.

  • Average, every day drivers will realize that speed limits in some areas are generally set slower than they are used to driving, and they'll grow tired of the warnings and turn it off.

    If Ford pushes out an update to create an optional 10 over buffer zone (if selected), at which point they'll get sued by an "activist" lawyer for getting a ticket while using Ford's system. At that point, the feature will quietly disappear in the next model upgrade.

    • What's worse is that this doesn't take into account the fact that OTHER drivers are likely not obeying the speed limits. Depending on the road, that can be anywhere from 5-10 mph over the limit.

      You know what's been proven to be more dangerous, in terms of causing more accidents, than exceeding the speed limit?

      In my current car it can be difficult to tell what your speed is unless you look at the speedometer frequently. There is no engine noise to go by. Newer models of my car read the speed limit signs and give a warning if it is exceeded by a certain amount and the adaptive cruise control already takes into account the speed limit (though it allows you to exceed it as well). The new model already reads speed limit signs. If a car is very smooth and quiet it can be quite easy to speed without realizing it.

    Cruise control already controls the speed of the car. Adaptive cruise control will drive at whatever speed it needs to drive at based on the distance to the cars in front and behind. Why not extend the adaptive cruise control system so that it will drive no faster than the speed limit (as determined by whatever this system uses) unless it has to drive faster due to the speed of the car behind (i.e. the car behind is going faster than the speed limit and therefore this car has to in order to not get rear-ended).

    It could then, like existing cruise control systems, be overridden by the driver if need be (via pressing on the accelerator pedal) but by default it would keep the driver at the speed limit unless it needed to go slower due to the car in front or faster due to the car behind.

      >> Adaptive cruise control will drive at whatever speed it needs to drive at based on the distance to the cars in front and behind.

      Not quite at least on my car (2008 Jag). Adaptive cruise has a max speed setting and a min distance setting. If the car in front suddenly speeds up my car will only speed up to the cruise speed you have already set. It helps to think of adaptive cruise more like an automatic slow up/brake than an automatic speed up/keep-up.
