Adaptive Cruise Control Mode

Description:

This parameter is used to indicate the current state, or mode, of operation by the Adaptive Cruise Control (ACC) device. The states characterize independent system states (e.g., it is not possible to express distance control active and overtake mode simultaneously). ACC must not switch itself off while active because the driver expects it to work. So if an error occurs, the ACC must signal that to the driver so that the driver knows that he has to switch off the ACC.000b = Off (Standby, enabled, ready for activation) 001b = Speed control active 010b = Distance control active 011b = Overtake mode 100b = Hold mode 101b = Finish mode 110b = Disabled or error condition 111b = Not available/not valid 000b � Off�Used to indicate the ACC is enabled in calibration or configuration and there are no faults that would prevent the system from operating. 001b � Speed Control Active�Used to indicate that ACC is on but not currently sending control messages. In other words, there is no target ahead a
