The ACC remains on, even after SSCC shutoff, to maintain a minimum following distance for a primary vehicle in which the ACC is employed and a forward vehicle. The ACC is deactivated after detection of an ACC shutoff trigger event, which may be driver application of the brakes of the primary vehicle, driver-initiated acceleration for a predefined time period, expiration of a predetermined time period, manual shutoff (e.g., via a switch or button), etc.
