Abstract: A cruise control method to control a driven vehicle includes: determining projected speeds of the driven vehicle at each of the predetermined-upcoming locations; determining a plurality of following times at each of the predetermined-upcoming locations of the driven vehicle and the projected speeds of the followed vehicle; determining whether at least one of the plurality of following times is less than the predetermined-minimum time threshold; and in response to determining that at least one plurality of following times is less than the predetermined-minimum time threshold, commanding, by the controller, the propulsion system of the driven vehicle to decrease the commanded axle torque by a torque adjustment in order to prevent each of the plurality of following times at each of the predetermined-upcoming locations from being less than the predetermined-minimum time threshold.

Abstract: 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.

Abstract: A method includes receiving a set speed, a maximum allowed speed, and a minimum allowed speed, wherein the maximum allowed speed and the minimum allowed speed define an allowed speed range; commanding a propulsion system to produce a commanded axle torque to maintain the set speed; monitoring a current vehicle speed of the vehicle; determining whether the current vehicle speed is between a first speed value and a second speed value, wherein the first speed value is the minimum allowed speed plus a first predetermined value, and the second speed value is the maximum allowed speed minus a second predetermined value; and in response to determining that the current vehicle speed is not between the first speed value and the second speed value, commanding the propulsion system to adjust the commanded axle torque in order to maintain the current vehicle speed within the allowed speed range.
