Like Olympic skiers racing in single file to reduce air resistance, two 18-wheeler trucks in Nevada recently proved that uncomfortably close convoys can save drivers fuel and money. The key, instead of bold Olympic athleticism, is robotic assistance. A computer-assisted truck was able to follow closely behind a human-driven truck perfectly, maintaining exactly 33 feet of distance between the vehicles. The promise is a future of safer, more fuel efficient, and more robotic trucking.
While Nevada is a friendly state for driverless cars, the system tested is only partially automated, with a driver in the computer-assisted truck still responsible for steering. In a way, that makes this a very, very advanced cruise control. The technology, developed by Peloton Tech, uses radar and a wireless link so that the following trucks travel at the same speed, braking simultaneously for safety, and doing so on an automated system that doesn't have the delays of human reaction time. In addition, the drivers of both vehicles also have a video display, expanding both drivers' vision and reducing blind spots.
