Cadillac to Roll Out Enhanced Super Cruise
Starting with the 2021 Cadillac CT5 and CT4, Cadillac will be introducing an enhanced version of the Super Cruise driver assistance feature. One of the many new features is automated lane change functionality which will allow the hands-free system to change lanes when requested by the driver if certain conditions are met.
“This is our most extensive update we’ve made to Super Cruise since its debut,” said Mario Maiorana, Super Cruise chief engineer. “We have made a number of improvements to make Super Cruise more intuitive, better performing and more accessible for our customers. In addition to the automated lane change functionality, we’ve made improvements to the user interface and hands-free driving dynamics.”
Lane Change On Demand
When Super Cruise is activated, the driver can turn on the turn signal to indicate that they would like to change lanes.The system will look for an acceptable opening in the lane, if the system determines that the lane is open, the vehicle will merge into the lane.
The system will also display messages to let the driver know when the automated change has begun or if lane change is unavailable. The messages include “looking for an opening” or “changing lanes” to keep the driver informed of the status of the lane change.
“In order to add automated lane change and provide our customers with the same level of confidence that they currently have in Super Cruise, we made improvements to both our software and hardware,” said Maiorana.
“This included improving rear-facing sensors and advanced software algorithms so that the system can confidently track vehicles approaching from the rear. As a result of these improvements, we are able to ensure that Super Cruise will hold in its current lane and only change when a sufficient gap exists.”
These advanced technologies, including precision LiDAR map data and real time GPS, help provide a detailed understanding of the surrounding road to determine lane change abilities. Cameras and radar sensors will continuously scan around the vehicle to determine if an acceptable opening exists. These factors all work together to ensure confidence when executing an automated lane change.
In addition to automated lane change, other Super Cruise enhancements include updates designed to improve performance and ease-of-use. Updates include:
- Addition of richer map information to enable automated lane change and improved functionality through turns and highway interchanges
- Improved software for better steering and speed control
- Enhancements to make it easier and more intuitive for drivers to engage the system
