Dynamic Radar Cruise Control (DRCC)

Making long highway drives easier and less tiring by maintaining a distance with the vehicle ahead

While staying within a preset speed range, the system maintains an appropriate distance between vehicles, helping make long highway drives less tiring. The system operates at all speeds, enabling to follow the vehicle ahead in low speed. This, in turn, helps reduce driver fatigue even in traffic congestion.

[1] Cruise control at preset speeds

The vehicle will drive at a constant preset speed.

[2] Control of deceleration cruising and follow-up cruising

Millimeter-wave radar determines the distance between vehicles. By adjusting speed within a preset range depending on the speed of the preceding vehicle, the system maintains a safe distance while ensuring follow-up and deceleration cruising.

[3] Acceleration speed control

Sensors (a camera and millimeter-wave radar) detect vehicles moving in and out of the lane ahead. This helps ensure smooth acceleration.

[4] Stop maintenance control (when all-speed cruise control is available)

The system slows or stops your vehicle when the preceding vehicle slows or stops. When the preceding vehicle speeds up, the system makes your vehicle accelerate accordingly, until it resumes the preset speed.

[When all-speed cruise control is unavailable:]

The system slows your vehicle to 30 km/h or above when the preceding vehicle slows down. The driver must manually control deceleration below 30km/h.


*Note: Dynamic Radar Cruise Control is designed to be used exclusively on highways and similar roads, and only works on vehicles. Please do not use it on general purpose city streets. Also, the system has certain limitations. When operating the vehicle, drivers should always pay close attention to their surroundings and be sure to maintain sufficient distances between their vehicle and preceding and following vehicles.
