Ford Engineers Test 'Predictive Logic' To Improve Cruise Control 112

But real engineers are working behind the scenes every day to make existing auto technologies more efficient. Take cruise control: Today, even adaptive cruise systems just throttle up when the car's speed drops and ease off when speed rises or a car gets too close. Today's cruise-control systems aren't predictive--meaning they don't plan ahead. At all. Now, engineers at Ford are adding predictive algorithms and more sophisticated powertain mapping to reduce the built-in overcompensation that ends up wasting fuel. Ford has mapped each vehicle's powertrain in much greater detail, and their prototype control systems look at grade steepness, load on the engine, and other variables every few seconds to predict what's likely coming up. Will the hill level off soon? Will the driver ask for more gas, or let up on the accelerator? Down the road, connected-vehicle and cloud-based data will build on these predictive developments--as will those autonomous vehicles you hear so much about. Think of this as a building block to the future."

    Cruise control is all too often a safety hazard on the interstate. Safety requires space, the more the better, between vehicles. All to often cruise control is the reason cars remain in close proximity, mile after mile.

    Oddly enough, there are virtually no traffic statistics that back up your claim.
    There is some speculation that cruse control would lull drivers to sleep, but in fact this happens no more with CC than withoug.
    As for slow passing, that's mostly a fallacy, because every cruise control allows driver over-ride, and passing a slower vehicle at one mph difference in
    speed is not some how more dangerous than passing at 5 or 10 mph. The same driver that will allow the CC to take them slowly around another car would pass slowly if managing their speed manually.

    Constant adjustment is part of the problem. People yoyo-ing up and down the highway are the real risk inducers.
