Ford Fusion Hybrid Lane Keeping System
I bought a 2014 Ford Fusion Hybrid with the Driver Assist Package.
We like most of the technology features we purchased. The one thing we are questioning is the functionality of the “Lane Keeping System”. The “Aid” feature is what seems to be lacking most. It does little, if anything, to help keep you in the the lane other than to alert you when you depart from it.
We do have the intensity of this feature set to high. If you have the system activated and the green lane line indicator is showing it functioning, you can allow the car to drift towards the line and while you may feel a little torque on the steering wheel in the direction of the center of the lane, it is certainly not enough to keep the vehicle from drifting completely out of the lane and the vehicle readily does so without driver correction.
The owner’s manual troubleshooting section for this feature states, “Why does the vehicle not come back into the middle of the lane always, as expected, in the Aid or Aid+Alert mode?” and then lists 5 items where the Lane Keeping System might not function properly. None of those conditions are present during our testing. We are running these tests on fairly straight, flat roads with good lane markings.
After some more research into the history of the Lane Keeping System at Ford, it looks like it has devolved in its capabilities since its introduction. It’s interesting to see how the present description of the system capabilities in Ford's marketing material has been subtly changed since its 2012 introduction to reflect this. The wording of the present description “..lane-keeping aid will actually apply pressure on the steering wheel to alert the driver to bring the car back into proper lane position” has been altered from the previous similar descriptions with “torque” being replaced by “pressure” and “and then nudge” has been replaced with “to alert the driver to bring”. So the present system really doesn't "Aid" at all anymore and now just "Alerts" the driver.
I cannot find a single article on this subject as to why Ford has crippled the Aid capability of the system since its 2012 model year introduction on Explorer. Has anybody else out there seen anything on this subject?
