Adaptive Cruise Control (ACC) System Description

Function 

The ACC system with Low Speed Follow (LSF) uses the multipurpose camera unit and the millimeter wave radar to calculate and adjust the vehicle speed to maintain the appropriate following interval between your vehicle and the vehicle detected ahead based on your vehicle speed and driving conditions. When another vehicle cuts in between your vehicle and the vehicle detected, the system switches the target vehicle to a new vehicle using the image information (vehicle and lane information) from the multipurpose camera. When the vehicle detected changes the lane or goes out of the detection range, the vehicle drives at the preset vehicle speed until detecting a new target vehicle. ACC system works with the cruise control system to adjust the vehicle speed.

The cruise control mode can be entered by operating the distance switch while the ACC is working.

Operation Conditions 

Basic Controls of ACC and Low Speed Follow (LSF) 

• The ACC system uses the millimeter wave radar to detect the vehicle ahead, determines the target vehicle and measures the distance to the target vehicle and its vehicle speed. (the system also uses the multipurpose camera as needed to determine the target vehicle based on the lane and vehicle position information)
• When there is no vehicle detected ahead, your vehicle drives at the preset speed. When there is a vehicle detected ahead, your vehicle follows the vehicle and drives within the preset speed.
