Ford Debuts New Curve Control Technology

June 30, 2010
3 min to read


DEARBORN, Mich. - For anyone who has experienced that moment of panic from rounding an exit ramp too quickly, Ford Motor Co. is offering a safety solution, reported The Detroit News.


The 2011 Ford Explorer -- due later this year -- has an upgraded electronic stability control system to better hug the road if a driver takes a curve too quickly. Ford demonstrated its curve control technology Monday.

The technology, in development for 18 months, builds on the current stability control system, using the same sensors to monitor how much the driver wants to turn, versus how much the vehicle is actually turning. If the input data determines the driver won't make the turn safely, it can slow the vehicle 10 miles per hour in a second, by cutting engine torque and applying the brakes.


In the first demonstration, with stability control but no curve control, an Explorer taking a curve at 50 mph wiped out orange cones as the rear end skidded out. Test driver and engineer Dave Messih said in real life, the car would have been on the shoulder -- a mistake that can result in a rollover. In the second demonstration, with curve technology engaged, Messih took the corner at the same speed and again kept his foot off the brake. The corrective technology braked and snapped the rear into place, executing the turn seamlessly. The sensation was dramatic but not jarring.


"We all like to think we're professional drivers and don't need this," said analyst Erich Merkle, president of Autoconomy in Grand Rapids. "Even good drivers in unfamiliar territory or in severe weather could benefit from this," he said. "Putting it in a family vehicle makes sense."


Taking a curve quickly contributes to 50,000 crashes a year in the United States, said Paul Mascarenas, vice president of global product engineering.


Ford's curve control will be standard on the Explorer and will be added to 90 percent of Ford's light trucks and crossovers by 2015. Eventually, it will find its way to cars, but because their lower center of gravity makes them less likely to roll over, trucks are the initial priority, said Sue Cischke, group vice president of sustainability, environment and safety engineering.

Ford's system is unique, said Ali Jammoul, chief chassis engineer. There is little incremental cost; it was developed as part of continuous improvement of stability control and no additional hardware is required.


For 2011, the Explorer switches to a car-based vehicle. Curve control is one of a raft of safety features including inflatable rear seat belts, adaptive cruise control and blind spot and cross-traffic alerts.


In 2001, problems with Firestone tires contributed to a number of Explorer rollovers that led to regulations mandating stability control. For the new Explorer, "Ford is going way overboard on safety features," Merkle said.
