Abstract
A vehicle includes at least one sensor in communication with a controller. The controller includes a ranging module configured to determine a headway between the vehicle and a lead vehicle traveling ahead of the vehicle. The controller also includes a headway learning module and an adaptive cruise control module. The headway learning module is configured to learn a set of personalized headways while the adaptive cruise control module is not engaged. The adaptive cruise control module is configured to maintain the vehicle at a personalized headway from the lead vehicle when the active cruise control module is engaged.
Claims20
A vehicle comprising:
- at least one sensor in communication with a controller, wherein the controller includes a ranging module configured to determine a headway between the vehicle and a lead vehicle traveling ahead of the vehicle;
- and
- the controller including a headway learning module and an adaptive cruise control module, wherein the headway learning module is configured to learn a set of personalized headways while the adaptive cruise control module is not engaged, and wherein the adaptive cruise control module is configured to maintain the vehicle at a personalized headway of the set of personalized headways from the lead vehicle when the active cruise control module is engaged.
A process for generating personalized adaptive cruise control headways, the process comprising:
- monitoring a vehicle headway, the monitoring occurring during a learn mode of operations, and storing the monitored vehicle headway as a learned headway during the learn mode of operations, wherein the monitoring includes identifying at least one current condition and correlating the at least one current condition with the learned headway;
- accumulating a sample set of learned headways having the same at least one current condition until the sample set of learned headways having the same at least one current condition has a sample size larger than a predefined minimum sample size;
- and
- combining the sample set of learned headways into a single personalized headway and providing the single personalized headway to an adaptive cruise control unit.
