SEOUL — Applications of Hyundai/Kia Motors’ ADAS (advanced driver-assistance systems) technology follow two types: on the one hand, the technology works to prevent accidents by complementing the driver’s attention with its safety features. In this article focuses on convenience features that reduce driver fatigue, specifically by assisting the driver’s maneuver of acceleration, braking, and steering. HDA (Highway Driving Assist), a semi-autonomous driving technology that maneuvers the vehicle on the highway at the preset speed and following distance, is probably the most well-known of such convenience features.

In order to best take advantage of the ADAS’s offerings, however, it is important for the drivers to understand the basic mechanism through which the technology functions. Doing so will help the drivers escape the common misunderstanding about ADAS that often causes them to misinterpret the correct working order as broken. In addition, understanding the new wave of government regulations on ADAS is also important to grasp the function’s range of application. Depending on the occasion, the regulations place limits on the function for safety reasons.

In present, three ADAS-applied convenience features are active on Hyundai/Kia models: SCC (Smart Cruise Control), NSCC (Navigation-based Smart Cruise Control), and HDA (Highway Driving Assist). We explore these functions, as well as the fourth function in development, in a Q&A format below.

Making Driving More Convenient: Smart Cruise Control (SCC)

Q. How does Hyundai/Kia’s SCC function?

In the past, cruise control could only maintain the designated vehicle speed set by the driver, such that when a slow car appeared ahead, the driver had to press the brake pedal, which in turn turned off the cruise control mode. In order to restart cruise control, the driver had to reset the whole function again, setting the vehicle speed and manually putting the car in cruise mode. In the United States, where long-distance travel often comes with sparsely populated, congestion-free highways, this cruise control function works reasonably well. In the highly populated roads of South Korea, though, the function was basically useless.

But new improvements to the cruise control technology may change all that. Smart Cruise Control, the newest evolved form of the tech, now maintains not only the vehicle speed but also the following distance. Like the old cruise control, SCC maintains the speed of the vehicle at the level set by the driver. Then, if a slow car appears ahead, it adjusts the speed to maintain the following distance; it returns to the preset speed only after the car ahead disappears from the forward-facing radar sensor.
