A cruise control method to control a vehicle includes: receiving, by a controller of the vehicle, a set speed, a maximum allowed speed, and a minimum allowed speed, wherein each of the maximum allowed speed and the minimum allowed speed is a speed boundary; a propulsion system to produce a commanded axle torque to maintain the set speed; monitoring a current vehicle speed of the vehicle; determining a current vehicle acceleration of the vehicle; determining a time that the vehicle will take to reach the speed boundary; determining whether the time that the vehicle will take to reach the speed boundary is less than a predetermined time threshold; and in response to determining that the time that the vehicle will take to reach the speed boundary is less than the predetermined time threshold, commanding the propulsion system of the vehicle to adjust the commanded axle torque.
