Ford Adaptive Cruise Control Explained – Video

Ford Adaptive Cruise Control Explained – Video

Ford and Vanderbilt University researchers are demonstrating this week that so-called phantom traffic jams could be minimized with widespread use of adaptive cruise control available today in most Ford vehicles.

The team conducted what is believed to be the largest, most realistic demonstration of its kind, showing that existing technology could help minimize phantom traffic jams, which happen for seemingly no reason and can cause hazardous traffic backups.

On a closed Ford test track, 36 drivers simulated normal highway traffic using adaptive cruise control, which can automatically slow down and speed up to keep pace with the car in front without getting fatigued or distracted. Those drivers then drove the same course, but without the technology – meaning they had to manually brake and accelerate the vehicle.

The results: vehicles using adaptive cruise control reduced the impact of a braking event more than those vehicles without the activated technology. Even with just one in three vehicles using adaptive cruise control, the test yielded similar traffic-busting benefits.

“A fun Fourth of July family road trip can quickly become irritating when traffic slows to a crawl – especially once you learn there was no reason for the gridlock,” said Michael Kane, supervisor, Ford Co-Pilot360 Technology. “We encourage Ford owners who have adaptive cruise control to use it during their summer travels in the hope this smart technology today can be that first step to help ease commutes.”

Ford currently offers adaptive cruise control on 71 percent of U.S. models.

“For years, traffic researchers and engineers have been looking to smart vehicle technologies to reduce traffic congestion, whether that’s vehicles that talk to each other or vehicles that can predict the road ahead,” said Daniel Work, civil engineering professor at Vanderbilt University. “This demonstration was a unique opportunity to understand how commercially-available active driver-assist technologies can be used to positively influence traffic flow.”

Work and lead PhD researcher, Raphael Stern, have been working with the support of the National Science Foundation to determine how smart technologies can provide a pathway to fewer traffic snarls – and reduced overall fuel consumption. They plan on publishing the results of the Ford demonstration in an upcoming academic journal.

Curse of the phantom traffic jam

As with crashes, human factors – such as merging into traffic without signaling, distracted driving, poor driving habits and reaction times, or unnecessary braking – are the main causes of phantom traffic jams. Think of it like this: Once one driver hits the brakes, a chain reaction can occur as other drivers tap their brakes, causing the flow of traffic to halt.

“Unlike the traffic jams caused by accidents or road construction, phantom traffic jams appear out of nowhere,” Work said. “Combined, traffic backups cost the typical American commuter on average an additional 41 hours a year sitting in traffic at a cost of $1,400 per commuter.” These figures take into account lost productivity, fuel burned while idling and increased wear and tear.

This year, the company is launching FordCo-Pilot360™, the most advanced suite of standard driver-assist technologies — a combination other non-luxury competitors don’t offer standard in North America — to help people navigate these challenging conditions.

Ford Co-Pilot360 includes standard automatic emergency braking with pedestrian detection, blind spot information system, lane keeping system, rear backup camera and auto high-beam headlamps. The new 2019 Edge is Ford’s first vehicle to offer adaptive cruise control with new lane centering technology, providing support on long road trips by helping keep the vehicle centered in its lane.

Ford’s adaptive cruise control technology – originally introduced in 2006 – has been consistently enhanced to help in a variety of conditions across the company’s cars, trucks and SUVs – like being specially tuned to work for F-Series F-150 and Super Duty customers who tow boats.

Adaptive cruise control versus the phantom curse: Ford’s demo

Three lanes of 12 vehicles each were tested on a closed high-speed oval simulating a highway. The lead vehicles in each lane slowed from 60 to 40 mph to mimic a traffic disturbance. Without the ACC technology, the drivers each braked harder than the vehicle ahead, which led to a braking wave that became more pronounced further down the traffic stream. In other words, the non-ACC drivers amplified the initial braking event, in some cases to the point where traffic slowed to a crawl.
