GM Makes Real Breakthrough in Braking System for Pickup Trucks with Trailers

The development of the American engineers uses a “digital” approach and works much better than conventional braking systems.

Electronically controlled brakes provide the system with excellent accuracy and significantly better efficiency. It even works with heavy road-trains.

Since pickup trucks that are popular in the United States and Canada are often used by owners to tow trailers weighing 4 tons, braking can be much more difficult for them. General Motors decided to optimize the proprietary eBoost braking system, which improves the efficiency of this system by adjusting it to the needs of towing cars.

A pickup truck from the current line-up of one of the above-mentioned brands equipped with eBoost was used for the experiment. This system uses an electronically controlled pump instead of a classic amplifier, which provides the desired pressure, depending on the force of the pedal. The pickup was equipped with new software, brake disc rotors, calipers and tires. After that, the vehicle was connected to a four-ton trailer and conducted a series of races with measurements.

The efficiency of the upgraded system was unexpectedly high, namely 20%. When braking from 100-0 km/h, the braking distance was 12 meters shorter than that of a similar car with a conventional eBoost system. Besides, the system smoothed out the trailer's vibrations. The results are shown in the video below.

GM calls its development as the Advanced Trailer Racing Concept (ATB), emphasizing that the technology is not currently used in production cars. However, it has every chance of appearing in one form or another, in Chevrolet and GMC pickups.
