MIT Creates Car Co-Pilot That Only Interferes If You're About To Crash

MrSeb writes "Mechanical engineers and roboticists working at MIT have developed an intelligent automobile co-pilot that sits in the background and only interferes if you're about to have an accident. If you fall asleep, for example, the co-pilot activates and keeps you on the road until you wake up again. Like other autonomous and semi-autonomous solutions, the MIT co-pilot uses an on-board camera and laser rangefinder to identify obstacles. These obstacles are then combined with various data points — such as the driver's performance, and the car's speed, stability, and physical characteristics — to create constraints. The co-pilot stays completely silent unless you come close to breaking one of these constraints — which might be as simple as a car in front braking quickly, or as complex as taking a corner too quickly. When this happens, a ton of robotics under the hood take over, only passing back control to the driver when the car is safe. This intelligent co-pilot is starkly contrasted with Google's self-driving cars, which are completely computer-controlled unless you lean forward, put your hands on the wheel, and take over. Which method is better? A computer backup, or a human backup? I'm not sure."

    While fully autonomous cars may be the more desirable future, computer backup systems like this are a more likely first step. Once people start getting used to cars making good decisions on the road, they will be more willing to give the computers even more control.

    I also find it hard to believe that a computer cannot get better at driving a car the most people. Sure there are emergency situations the require extreme skill and judgement calls, but how many people are good in those situations? I have seen many drivers who react 100% wrong in dangerous situations. They don't understand the dynamics of the car and get confused in a panic. Computers don't have this problem.

    I disagree. Human drivers are always a disaster waiting to happen. Computers don't get drunk. Computers don't get angry. Computers don't get sleepy. Computers aren't trying to impress a woman.

  8. Trolley problems? by JoshuaZ · · Score: 5, Interesting

    There's a whole class of philsophical problems about when to save one life v. n lives http://en.wikipedia.org/wiki/Trolley_problem. One very awkward thing about this is that advanced emergency driving systems may need to address questions that we are fundamentally uncomfortable answering or discussing. Should a system for example protect the life of the people in a car as opposed to the life of people in a nearby car that they might crash into? Which gets higher priority. Does the number of people in each car matter? Exactly what the cars do in the few seconds leading up to a crash could alter this. Essentially this sort of thing may force us to examine difficult ethical problems.

      That was part of the angst of Will Smith's character in the I, Robot movie. A robot logically decided to save him rather than attempt (and probably fail) to save a little girl - a choice that deeply conflicted with his (and probably most peoples) morals.

      I don't think so. Consider a related problem where a train is equipped with a camera to see if there is an obstruction on the track, and an AI system which can automatically decide to halt the train. Such systems certainly exist, and differ from the smart car example only in the number of dimensions available for movement (the car has two directions available, while the train has only one).

      By your contention, the camera/AI system is ipso facto making an ethical choice about the life and death of a person who happens to be standing on the tracks vs the risk of accident or death of a traveller in one of the wagons who needs to go to hospital immediately (or else we do, by deciding to build it).

      But that is ludicrous. The system merely solves a problem about how strongly to apply the brakes. There is no ethics invovled whatsoever, nor any choice about life and death. Merely a very simple control problem. We can certainly ask what can be done about this particular problem in general, eg how to prevent people from standing on tracks etc, but clearly the actual train/AI (and whether we should build them or not) has no ethical role at all in this.

      The fact is that the statement of the problem here (a person standing on the track while a traveller may die from stopping the train) is independent of the train/AI aspect, which is just a detail. Making it *about* the train/AI is inappropriate.

    The only thing that the computer can't be designed to cope with is complete hardware system failure. Are the automotive companies really prepared to put dual systems in the vehicle with backup power? And for that matter, are they going to be willing to disable the vehicle if a sensor is out of commission? They will really need to do that because drivers will become used to depending on the system.

    Correct. However, it requires a pilot to program and monitor its progress as well as very specific requirements for onboard equipment, crewmember training and triple redundancy in the event of malfunctions. I've had numerous Cat III approaches to a safe landing and it works but I wouldn't say the computers are better than the pilots. Its only used when there is not adequate visual reference for the pilot to do it. After the aircraft finishes its rollout in a straight line using ILS, the pilot still has to find his way to the gate with visibility at only a few meters.

    Auto pilot for landing exists, but it requires ground equipment that is only available in the biggest airport, and it's only installed in the biggest airliners.
    The vast majority of landings are done manually by the pilots, while the autopilot is sometimes used in extreme conditions (fog especially).

    Actually, the autopilot will usually take you to the "minimums" which is usually set to several hundred feet above the deck at which point, an audible alarm is sounded "Minimums!" and the pilot is expected to take over the throttles and yoke. If that does not happen, the AP will make an attempt at landing using nothing but the ILS and glidescope, provided you are nav and gs captured (which you should be while landing).

    In important industrial applications, a set of 3 sensors is used.

    If they all agree, fine.
    If one of them disagrees by a certain margin, use the information of the other two and light up a warning.
    If they all disagree, turn it to manual and blast the alarms.

    In really important stuff, like nuclear stuff, it is used up to 5 sensors, each with a different functioning principle.
