**Introduction to the Universal Super Cruise System**
The rapid advancement of autonomous driving technology in recent years has become a focal point for both traditional automakers and IT companies. Currently, the level of automation in production models available or soon to be launched ranges from Level 2 (partial automation) to Level 3 (conditional automation). In September last year, the overseas version of the 2018 Cadillac CT6 became the first vehicle to feature General Motors' new Super Cruise system. This system enabled highway driving with hands-free operation, allowing drivers to take their hands off the wheel. But what exactly is this system, and how does it compare to Tesla Autopilot and Audi AI? Let’s explore.
**Can the Super Cruise System Go Hands-Free?**
The Super Cruise system is classified as a Level 2 autopilot system by the SAE (Society of Automotive Engineers). It allows for single-lane highway driving using high-definition map data. The operating speed range is between 0 and 143 km/h (approximately 80 km/h), and the system can be activated within that range. Beyond the standard ACC adaptive cruise control found in many vehicles, Super Cruise automatically keeps the car centered in its lane and handles turns, making it possible for the CT6 to drive itself on highways without requiring the driver to hold the steering wheel. This significantly reduces driver fatigue during long trips.
However, one limitation of the system is that it cannot change lanes or overtake automatically. If a slower vehicle is ahead, the driver must manually switch lanes. Despite this, the system still offers a significant improvement over basic driver-assistance systems, as it allows the driver to keep both hands off the wheel while monitoring the road.
**Safety and Legal Considerations**
In the U.S., some state and local laws require drivers to keep their hands on the steering wheel at all times. However, when Super Cruise is engaged, the driver can safely remove their hands, and this practice is permitted under current regulations. GM claims that the system meets strict safety standards, thanks to its use of high-definition maps, advanced sensors, and sophisticated software. These elements work together to ensure a reliable and secure driving experience.
**Hardware Composition**
Super Cruise uses a variety of sensors to monitor the environment, including one long-range radar, five short-range radars, a monocular camera located in the interior mirror, four surround-view cameras, a GPS system, two inertial navigation sensors, and a control unit for storing high-definition maps. Additionally, a camera mounted on the steering wheel monitors the driver's attention. An infrared illuminator helps detect the driver’s face in low-light conditions, and a warning light on the steering wheel changes colors to alert the driver depending on the situation.
**How to Use the System**
To activate Super Cruise, the driver must first start the adaptive cruise control. Once the system is active and the vehicle is on a compatible highway, a gray steering wheel icon appears on the dashboard. Pressing a button on the left side of the steering wheel activates the system, allowing the vehicle to drive autonomously on the highway.
**Hands-Free Doesn’t Mean Distracted**
Although Super Cruise allows drivers to remove their hands from the wheel, it is still a Level 2 system that requires constant monitoring. The system uses facial recognition to track the driver’s attention. If the driver becomes distracted, the system will alert them through sound, vibration, and flashing lights. If ignored, the vehicle will gradually slow down and stop, then notify the service center via connected car technology.
**Comparison with Tesla Autopilot and Audi AI**
GM’s Super Cruise is the first hands-free highway system in the industry. Compared to Tesla Autopilot, which still requires the driver to keep their hands on the wheel, Super Cruise offers more freedom. After several incidents, Tesla changed its terminology from “autonomous driving†to “autonomous assistance†to avoid confusion. Tesla also checks if the driver’s hands are on the wheel and will force the vehicle to stop if they are not. This encourages drivers to stay alert and ready to take control at any time.
Tesla and GM have different approaches to autonomous driving. Tesla aims for full-point-to-point automation, while GM focuses on enhancing the driving experience while maintaining the joy of driving.
**What About Audi AI?**
Audi’s new A8, launched in Germany, features a Level 3 system called “Audi AI.†It can drive autonomously at speeds below 60 km/h under complex traffic conditions, completely freeing the driver’s hands. Unlike Super Cruise, which operates only on highways, Audi AI is designed for urban environments. It includes more advanced sensors, such as a laser radar, to improve obstacle detection. This reflects the higher demands of Level 3 systems, which require more complex control strategies and sensor configurations.
**Conclusion**
Each system has its strengths and limitations. While Super Cruise offers hands-free highway driving, it lacks lane-changing capabilities. Tesla Autopilot emphasizes driver engagement, and Audi AI aims for urban autonomy. As the industry evolves, these systems continue to push the boundaries of what is possible in autonomous driving.
