Cadillac Intros Super
April 17, 2017
The 2018 Cadillac CT6 will feature Super Cruise, the industry’s first
true hands-free driving technology for the highway. Unlike other driver
assistance systems, Super Cruise utilizes two advanced technology
systems — a driver attention system and precision LiDAR map data — to
ensure safe and confident vehicle operation.
These systems are added to the
network of cameras and radar sensors in the CT6, providing a more
data-rich approach to driver assistance that is unique in the industry.
Super Cruise delivers comfort and convenience for long-distance travels
and daily commutes. In addition, its hands-free capability and driver
attention system help the driver safely complete common tasks in the
car, such as using the navigation system, adjusting the audio system or
taking a phone call.
Super Cruise adds automatic lane-centering to CT6’s existing suite of
driver assistance active safety technologies, enabling automatic control
of speed and steering during highway driving. The system, which was
designed to promote driver safety and convenience, will be available
“Super Cruise is a more technologically advanced hands-free driving
solution, which in terms of capability, integration and validation is
uniquely focused on customer convenience and safety,” said Johan de
Nysschen, Cadillac president. “Cadillac’s philosophy is to elevate
driving. Super Cruise enables safe, simple hands-free driving for the
Driver Attention System Enables Safe Operation
“When we were developing Super Cruise we knew it was important to keep
the driver engaged during operation. That’s why we’ve added a driver
attention function, to insist on driver supervision,” said Barry Walkup,
chief engineer of Cadillac Super Cruise.
The driver attention system uses a small camera located on the top of
the steering column that focuses exclusively on the driver and works
with infrared lights to track head position to determine where the
driver is looking whenever Super Cruise™ is in operation.
Existing driver assist systems only rely upon steering wheel input and
warning messages to request driver attention and control. Cadillac is
the only manufacturer to monitor driver attention to the road ahead when
Super Cruise™ is engaged.
If the system detects the driver has turned attention away from the road
ahead for too long, it will prompt the driver to return their attention
to the road ahead. If the driver does not immediately refocus on the
road, Super Cruise™ will continue to safely steer until a further
escalation of alerts prompts the driver to resume supervision.
If the system determines continued inattentiveness, a steering wheel
light bar guides the driver to look at the road or take back control of
the wheel. Additional alerts can include visual indicators in the
instrument cluster, tactile alerts in Cadillac’s Safety Alert Seat and
audible alerts, if necessary. In the limited event of an unresponsive
driver, the Cadillac CT6 utilizes the full capability of onboard driver
assistance technologies to bring the car to a controlled stop and
contact OnStar to alert first responders, if necessary.
Precision LiDAR Map Data
Super Cruise™ is the first assisted driving technology that will use
precision LiDAR map data in addition to real-time cameras, sensors and
Data from on-board cameras, GPS and radar sensors is a key component of
most assisted driving systems. The car uses the real-time data provided
by the cameras and sensors to govern steering, braking and acceleration.
Super Cruise adds to this formula using advanced laser technology in
development for future autonomous vehicles: a LiDAR-scanned map
Combined with the real-time data from cameras and GPS sensors, the
precision map governs system use, enabling it in only the areas where
appropriate road conditions are detected. The combination of real-time
data with precision mapping also improves vehicle control through curves
This advanced map data restrains Super Cruise use to divided,
limited-access highways — highways with defined “on-” and “off-ramps.”
This approach focuses Super Cruise’s benefit on highway commutes, a
large part of many consumers’ daily driving routines, as well as
long-distance travels. It eliminates variables such as intersections and
other less predictable potential hazards that can be prevalent on rural
roads or city streets.
“The development of Super Cruise reflects a responsible and
safety-oriented approach to the rollout of this advanced technology,” de
precision LiDAR map was developed specifically for Super Cruise.
Engineers mapped every mile of limited-access highway in the U.S. and
Canada, providing detailed information to the car about the road ahead.
This pairs with improved accuracy GPS, measuring real-time location in a
fashion four to eight times more precise than traditional GPS.
“American drivers travel twice as many miles on urban and suburban
highways as they do on rural roads,” Walkup said. “Super Cruise™ allows
hands-free driving and operates only within the environment where it has
the most benefit. While it is technically possible for the technology to
drive hands-free on other kinds of streets and roads, we feel strongly
that this targeted approach is the best to build consumer and regulatory
confidence and enthusiasm for advanced mobility.”
Super Cruise will be offered as an option on the 2018 Cadillac CT6
prestige sedan, starting this fall in the U.S. and Canadian markets.
