New Ford System Controls Speed Limiting Automatically

A new Intelligent Speed Limiter is expected to be launched by Ford this year. A number of vehicles now display the local speed limit on their navigation screens, some using cameras to ensure that the limit hasn’t changed since the navigation database was created. The system being introduced in the next-generation Ford S-Max people-mover goes the next step, and actually controls the speed of the vehicle itself.
"Drivers are not always conscious of speeding and sometimes only becoming aware they were going too fast when they receive a fine in the mail or are pulled over by law enforcement," notes Stefan Kappes, Active Safety Supervisor, Ford of Europe. "Intelligent Speed Limiter can remove one of the stresses of driving, helping ensure customers remain within the legal speed limit."
The Intelligent Speed Limiter might seem like a breakthrough but it simply builds on technology already used in a growing number of vehicles, including vision systems and Active Cruise Control. The latter allows a motorist to set a preferred speed and relax. It will automatically adjust to the pace of traffic and, on some models, even bring the vehicle to a complete stop in a traffic jam.
A number of new vehicles, meanwhile, use camera systems to watch out for potential collisions and to ensure a car doesn’t drift out of its lane. Some also watch for speed limit signs, flashing the correct number up on the navigation screen or a Head-Up Display. Ford combines these technologies together. The Limiter automatically sets the vehicle’s cruise control to the legal limit, adjusting speed when the limit changes during a drive. To smooth out the ride, Ford says the system cuts gas flow rather than hitting the brakes.
The decision to launch the system in Europe first was for several reasons. The Continent uses more uniform traffic sign shapes, for one thing. But European motorists also face generally lower speed limits and stricter enforcement – including an estimated 35,000 traffic cameras. The maker says it may expand the use of the Intelligent Speed Limiter to other vehicles besides the seven-passenger S-Max. And Ford may also offer it in other markets, including Asia and possibly the U.S. where enforcement has been increasing – even though many states and cities have begun to cut back on the use of speed and red light cameras.
Volvo is expected to launch a similar system in its new XC90 sport-utility, and similar technology could become more commonplace in the years ahead. Indeed, the autonomous vehicles we’ll start to see hitting the road in the coming years will, by definition, need to be capable of automatically detecting and maintaining local speed limits.
