Active Cruise Control (ACC): Notes
The 2nd generation ACC system was introduced on the E63/E64 (6 Series), with some minor modification this further developed ACC is offered in the E90.
The Active Cruise Control (ACC) option provides cruise control function plus is able to maintain comfortable spacing from the vehicle a head.
The distance from the vehicle ahead can be selected from 4 fixed timed separations. As speed changes, so does the distance to the vehicle ahead. The legally prescribed minimum distance is not undershot in the adjusted status.
Differences between the Active Cruise Control option in the E90 and the Active Cruise Control option in the E63/E64:
- In the E90, the data for the Longitudinal Dynamics Management is evaluated in the LDM control module.
- In the E63/E64, the data for the Longitudinal Dynamics Management is evaluated in the ACC control module.
IMPORTANT:
Cruise control does not relieve the driver of his personal responsibility. Cruise control is a comfort system. Adjustments by the driver will always have a higher priority than cruise control. The driver should decide whether (and how) the system is used based on road and traffic conditions and visibility.
