GM engineers have come up with a trailer braking concept that has the potential to dramatically reduce stopping distances – in fact, it allows a truck and trailer to stop in the same distance as a truck by itself at its gross vehicle weight rating. This is done using existing components, including GM’s eBoost braking system.

“The industry tends to focus on the big towing claim, but the overall towing experience is just as important and every hill climb has a hill to descend on the other side,” said Tim Herrick, vice president of Global Product Programs.

Utilizing the truck’s eBoost braking system, GM engineers integrated a trailer with a similar eBoost system and upgraded hardware components such as brake rotors, calipers and tires.

With eBoost systems on both the truck and trailer and proper software to enable communication, the stopping distance of a truck and trailer improved by up to 20% from 100 kmh to zero when compared to an identical truck and trailer using traditional electric trailer brakes – that’s about a 40-foot difference.

The technology uses the existing seven-pin trailer wire connector and without the need for any extra connections. The advanced trailer braking also helps mitigate trailer sway by using stability control.
