Advanced Driver Assistance System
Going beyond convenience for the driver to rider safety
On Mohave Desert, located in the Southern California, six Genesis vehicles are driving in single lane. When the speed per hour reaches 40 miles (about 64 km), the drivers of the rear five Genesis quickly jump out of the car, and the only driver in the front car soon is faced with a dangerous moment where his eyes are covered with an eye bandage. However, when the big truck makes a sudden stop, to everyone’s surprise, all Genesis vehicles in the lane stop safely.
Entitled “The Empty Car Convoy”, this video clip was released in June last year and soon hit 2.57 million views on YouTube within 10 days since release, becoming the talk of the world. The very core technology applied in the cars that starred in the video is called Hyundai Motor's “Advanced Driver Assistant System”.
Future Automotive Technology Geared Towards “Safety”
Do you recall Kitt from “Knight Rider”, the TV series aired 30 years ago? The Kitt we are talking about, featured in the series, was an intelligent car which was able to communicate with the driver and drive autonomously upon demand. Autonomous vehicle – a science fiction-like story – has now become a reality. Now, a car’s engine can be turned on with a remote vehicle startup. The car system can also detect the road signals and pedestrians, and also avoid obstacles. Such features in a vehicle have become possible with diverse cutting-edge technology. Hyundai Motor, to this end, added one more value – that is, “safety”.
The previously mentioned features seem to be something for the drivers, but in fact, they are all based on the value of safety. According to Korea Road Traffic Authority, 95% of the car accidents occurred on the road are solely caused by the driver’s carelessness, and 70% of the casualties from car accidents are due to negligence during driving, including mobile phone use, phone calls and falling asleep while driving, all of which hint that safety is something that many neglect. People always dream of a smart car that can drive us to the destination in difficult situations when the weather is bad due to rain or fog or when we are drunk. Ultimately, safety is the goal, and convenience is the means.
ADAS technology, the desire for safety going beyond convenience
Hyundai Motor's ADAS technology is mainly divided into systems of cognition, judgment and control. Corresponding to the human eyes, the cognitive feature is about perceiving the environment with a sensor or camera, while the judgment action is similar to that of the human brain with the feature having to do with managing the signals or determining the direction the vehicle should head to with the help of a controller. Lastly, the control system, through motion and steering control, is in charge of direct movement, and this system is similar to the blood vessels, muscles and nerves in human. Through the perfect harmony of these three elements, Hyundai Motor has come up with a variety of cutting-edge devices.
LKAS, Lane Keeping Assist System
Falling asleep while driving is said to be more dangerous than drunk driving by 12 folds. In the blink of a moment, the car could break away from the road and end up in an irrecoverable accident. In order to prevent this, LKAS perceives the front lane with the camera installed on the windshield glass and helps the car autonomously come back to its lane when it breaks away from lane without turn signal.
AEB, Autonomous Emergency Braking System
In case the driver missed the proper timing to push the brake pedal when an emergency brake is needed, AEB starts operating. It assesses the possible clash depending on the distance between the cars and the driving speed to properly operate the brake in such a way that clash is avoided.
VSM, Vehicle Stability Management System
VSM helps the car to stay in balance and maintain proper position when brake is used on the roads that are slippery due to snow or rain or are slanted or curvy.
BSD, Blind Spot Detection
With the radar sensor on the rear bumper, BSD signals the obstacles or fast moving cars that are in the blind spots of the rear view. This helps the driver not only prepare against possible accidents but also to anticipate danger and avoid it.
SPAS, Smart Parking Assist System
SPAS helps pre-detection of the surrounding obstacles through an external sensor during parking; it also autonomously handles the steering wheels. The driver can do a parallel parking or perpendicular parking by only pushing the pedals.
HAC, Hill Start Assist Control System
Hill Start Assist Control System operates the brake autonomously when the car restarts after stopping on a steep road so that it would not be pushed back. This is a safety feature necessary for beginner drivers who are not that skillful in steep road driving.
FCWS, Forward Collision Warning System
With the front view detection camera, the vehicle can perceive the lane and the vehicles ahead, and when a possible clash is predicted, an alarm would ring and steering wheel vibrates in warning to help preempt the accident.
Advanced Smart Cruise Control
This system helps the vehicle to maintain a certain distance away from the front car via the radar sensor so that the driver need not go back and forth the accelerator and brake pedals in the chronically congested roads or busy city roads. In particular, it has enhanced convenience through autonomous distance control and acceleration to the settled speed after restarting.
