ACC EXTENDED MODE OPERATION
First Claim
1. An adaptive cruise control (ACC) system that remains in an operational state during inactivity of an associated set speed cruise control (SSCC) system, including:
- an ACC system (14) in a first vehicle that detects at least one braking initiation condition, and decelerates the first vehicle in response to the at least one braking initiation condition;
wherein the ACC receives a signal indicative of a SSCC system (16) being deactivated upon initiation of a deceleration event, and continues to operate in an extended mode of operation during the deceleration event.

Abstract
When employing an a cruise control system in a commercial or heavy-duty vehicle, an adaptive cruise control (ACC) system (14) is activated upon activation of a vehicle or set-speed cruise control (SSCC) system (16). The ACC (14) remains on, even after SSCC shutoff, to maintain a minimum following distance for a primary vehicle in which the ACC (14) is employed and a forward vehicle. The ACC (14) 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.

14. A method for maintaining adaptive cruise control (ACC) operation after set-speed cruise control (SSCC) deactivation, including:
-
determining whether a SSCC system (16) is active in a primary vehicle; activating the ACC system (14) upon a determination that SSCC is active, to maintain the primary vehicle at a predetermined interval behind a forward vehicle; maintaining the ACC system (14) in an ON state, regardless of SSCC system (16) deactivation, at least until an ACC shutoff trigger event is detected; and deactivating the ACC system (14) after detection of the ACC shutoff trigger event. - View Dependent Claims (15, 16, 17, 18, 19)

20. An adaptive cruise control (ACC) system (12) with extended mode operation, including:
-
a sensor (26) that detects the position of a forward vehicle relative to a primary vehicle in which the sensor (26) is installed; and a processor (18) that; receives a measurement signal from the sensor (26) indicating a distance between the primary vehicle and the forward vehicle; transmits a command signal to a braking system (24) that maintains the primary vehicle at a predetermined interval behind the forward vehicle; maintains the ACC system (14) in an ON state, regardless of deactivation of a SSCC system (16) in the primary vehicle, at least until an ACC shutoff trigger event is detected; and
deactivates the ACC system (14) after detection of the ACC shutoff trigger event. - View Dependent Claims (21, 22, 23, 24, 25)
