An advanced driver-assistance technology from GM called Super Cruise allows drivers of its Cadillac CT6 to reduce the fatigue of long-distance travel with a hands-off-on-the-highway system.

In development for more than five years, it relies on a fusion of radar, ultrasonic sensors, cameras and GPS, as well as two important additions that set the system apart from other Level 2 technologies – lidar map data and an innovative head tracking Driver Attention System (DAS) to ensure drivers are looking at the road ahead.

The system uses a combination of sensors, cameras, GPS, and lidar maps to allow drivers to take their hands off the wheel on pre-mapped roads in the USA and Canada.

General Motors’ Super Cruise hands-free highway driving system, available on the 2018 Cadillac CT6, makes use of Trimble’s Real-Time eXtended (RTX) GNSS/GPS correction technology to help maintain lane position.

Trimble’s RTX technology provides real-time, multi-constellation GNSS positioning capable of achieving better than 1.5in accuracy. Trimble says standard GPS signals can drift up to 25ft, which could cause incorrect lane identification.

RTX is designed to improve lane-level positioning performance for semi-autonomous and autonomous vehicles, when used in conjunction with high-definition maps, cameras, radar and inertial sensors.

RTX technology uses signals captured by more than 100 Trimble GNSS reference stations around the globe.
