A deeper look into Ford's Pre-Collision Assist with Pedestrian detection
Dearborn, MI – Back in October, Ford released information of its new safety system “Pre-Collision Assist with Pedestrian Detection.” It's a system that many automakers are working on, but the only one that I was able to test at Ford's recent Executive Briefing event in Dearborn, Michigan.
The Pre-Collision Assist system with Pedestrian Detection uses both radar and camera technology to scan the roadway ahead. The camera is situated behind the rear-view mirror; while the radar is located behind the front bumper. There's a big need for both devices, as the radar measures speed and objects; while the camera is used to identify and classify those objects. The combination of the two provide the necessary data to make a quick safety decision on behalf of the driver, who's failing to make the appropriate actions.
When used, the system initially alerts the driver with a red beam flash on the windshield to react to the oncoming object, be it a vehicle or pedestrian. If the driver has still failed to act, it will brake for them with full-force, if needed, to avoid the impending accident.
With these types of autonomous actions, there are limitations. One is bad weather, where rain, fog, or snow could play a factor in interfering with the camera lens. When one part of this system doesn't function, the whole detection part won't work.
Additionally, the radar can sense things only 200 metres ahead, while the camera has a 50-100 metre scanning border. Therefore, if you're going above 80 km/h, the system will probably not have enough time to fully stop, but would brake as much as it could to limit the damage or injury. It's not a perfect system, but one that's better than the last without any pedestrian detection whatsoever.
“Many accidents can cause injury and death and we at Ford believe pedestrians are the biggest challenge,” said Aaron Mills, Technical Specialist – Advanced Driver Assistance Systems at Ford Motor Company. “Sensors improve as technology evolves to help with these scary scenarios.”
When asked about whether the red alert was enough warning over other tools such as seat vibration or chimes, Mills added, “with all of our simulated studies, we found that the red alert and muting of the radio were the most effective in getting the driver's attention.”
This system will be first used in the all-new mid-size Ford Mondeo sedan in Europe. Even though, the Mondeo is the Fusion in North America, Ford didn't announce which vehicle it would be first placed in. We would expect this new technology to come to North America in late 2015.
Not surprisingly though, the car we were testing the system in was the Ford Fusion. Unfortunately, they didn't have any fake pedestrians on site, but we were able to fully test the pre-collision stops on vehicles ahead. We tested it going 50 km/h and it stopped with ease as my foot lay flat on the floor mat.
Autonomous braking is an important safety system for many automakers, considering the amount of accidents that are caused by driver distraction. If automakers can save lives with new technology, it's a safety feature that's worthy of allocating money towards. As this system improves, Ford feels that down the line, they will be looking at improving on it, which could mean a wider and longer camera and radar, as well as the detection of animals.
