GM’s new tech can stop a truck (and trailer) much, much faster
GM has shown a trailer-braking concept system that can stop a truck and trailer in the same distance as the truck on its own—at half its gross vehicle weight rating. Possibly the best part of the system is that it can use existing components.
The system uses GM’s “eBoost” system, with a trailer that is similarly equipped. Having the eBoost setup on both the truck and trailer, with custom software to connect the two, lets the braking systems “cooperate” for the maximum possible stopping time. The system can cut sixty-to-zero-mph braking by up to 20%, or around 40 feet. It uses the existing seven-pin trailer wire connector, and also integrates stability control to reduce trailer sway.
No trailers are sold with the system yet, but GM appears to be ready to help trailer makers step up to the plate.
As a side note, GM has helped individuals who tow by including a simple label on each truck which shows its rated towing capacity—a sadly belated industry first.
