A cruise control system, the vehicle including the same, and the method of controlling the cruise control system are provided to improve fuel efficiency by changing control target vehicle speeds by continuously predicting vehicle speeds and variations in required driving forces on roads with various slope variations. Additionally, driving performance is improved by using kinetic energies and preventing unnecessary acceleration and deceleration in comparison with conventional vehicles. Driver convenience and satisfaction is also improved by preventing an unintended operation stop of the cruise control system caused by frequent acceleration and deceleration on roads with substantial slope variations in advance and by preventing unintended acceleration/deceleration on roads with frequent slope variations.

An auxiliary battery recharging control method and apparatus are provided. The method includes determining whether a recharging prohibition condition is established, based on first state information of a vehicle and second state information of a first battery, at regular recharging intervals, when a periodic recharging mode is executed, based on a first ignition (IG) voltage. Recharging is executed based on whether a critical recharging condition is established using third state information of a second battery, when an automatic recharging mode is executed, based on a second IG voltage. Additionally, a voltage variation is calculated of the second battery selected from the third state information, and at least one of a recharging time and a recharging voltage is adjusted, based on the calculated voltage variation, or the recharging interval is adjusted, based on the calculated voltage variation.
