Forward Radar Systems
ACC for Touareg
J428 Distance Regulation Control Module
J850 Distance Regulation Control Module 2
The Touareg uses a Stop and Go ACC system. During ACC operation the vehicle follows another vehicle (distance-controlled)
and can brake to a standstill, if required. After a vehicle standstill has been detected, the vehicle is held by the hydraulic brake
system (similar to Auto Hold function). The driver must give a brief tap or push of the accelerator pedal to continue distance
regulation.
Advantages
• The dual LRR antenna design enables a range of up to
656 ft (200 m) and a 42° field of view
• The overlap angle has been substantially increased
using two radar sensors. At 90 ft (30 m) ahead, the
detection range is wider than a 3-lane highway with a
width of approximately 52.5 ft (16 m)
Instrument Cluster Control Module J285
Limitations
• The accelerator pedal must be pressed to activate
ACC following distance)
• ACC is only capable of providing approximately 30%
of the vehicle maximum brake force
