This Is How The Ford F-150's Taillight Scales Work
Let's look at the engineering that lets the 2021 Ford F-150 tell you how much weight you just threw into your truck.
The 2021 Ford F-150 has a feature called “Onboard Scales,” which uses the taillights to help make sure you don’t overload the truck beyond its payload capacity. Here’s how this works.
I’m always impressed when automotive software engineers use already-existing hardware to develop useful new features. Ford’s Trail Control (off-road cruise control) and Trail Turn Assist (a feature that brakes the rear inside wheel to allow for a tighter turn) are two great examples that take advantage of drive-by-wire and the vehicle’s highly capable ABS system.
Now there’s Onboard Scales. My taillight-fetishizing coworker Jason Torchinsky pretty much had a stroke when he saw this feature, as you could probably tell by his article. While that story did a great job contextualizing what this moment means in the grant scheme of taillight history, it didn’t really describe how the system works. Neither did our introductory article in April.
Seeing as Jason’s taillight story is the most-clicked-upon story on Jalopnik right now, and seeing as I just had a chance to test out Onboard Scales at a Ford press event yesterday, I thought I’d write a bit about how the tech works. It’s not going to be one of my patented deep dives, but it’ll be a nice, light overview. Here we go.
