The SCC (Smart Cruise Control) is an advanced system compared to the CC (Cruise Control), which helps a driver maintain a safe distance with a vehicle head using a distance sensor (radar). The sensor monitors the vehicle speed of the car ahead. The SCC system operates as below:

1. The radar sensor installed in the SCC detects a vehicle in front.
2. The SCC module computes adequate acceleration or deceleration speed based on the speed and distance of the preceding vehicle.
3. The SCC module then sends the data of "Acceleration or deceleration speed" to the IEB (Integrated Electric Booster) module via CAN communication.
4. The IEB module calculates torque required for the vehicle speed adjustment. If it needs to decelerate, it will begin brake control. If it needs to accelerate, it will send "Required Torque" to the engine Control Module via CAN communication.
5. Then, the engine Control Module will accelerate.

   The FCA (Forward Collision-Avoidance Assist) is a function that helps a driver avoid a collision or minimizes the impact from it when the driver fails to brake at a right timing or with adequate braking power. The FCA system operates as below.

1. The FCA module senses a car/pedestrian in front of the vehicle using an installed radar sensor and LKA-L camera sensor.
2. The FCA module then verifies the FCA target vehicle/pedestrian based on the collected data.
3. The FCA module computes adequate acceleration or deceleration speed based on the speed and distance of the preceding vehicle.
4. The FCA module sends the "Required acceleration or deceleration speed" to the IEB/ESP module via CAN communication.
5. The IEB/ESP (ESC/Electronic Stability Control Program) module will calculate a torque required and begin brake control.
