1. A full speed range adaptive cruise control system for a vehicle that stops at an intersection, the full speed range adaptive cruise control system comprising:
one or more controllers in electronic communication with an engine start-stop system, wherein the one or more controllers execute instructions to:
receive localization data and situational data related to the vehicle;
determine, based on the localization data and the situational data, that the vehicle is approaching an intersection and will come to a stop at the intersection, wherein the vehicle is part of a queue including one or more surrounding vehicles;
in response to determining the vehicle is approaching and will come to a stop at the intersection, determine a position of the vehicle within the queue and an overall length of the queue;
calculate an adaptive launch time based on at least the position of the vehicle within the queue, the overall length of the queue, the situational data, and a timing delay associated with the queue, wherein the adaptive launch time indicates when the full speed range adaptive cruise control system instructs the vehicle to resume driving after stopping at the intersection, and wherein an engine start time and an engine stop time of the engine start-stop system are both a function of the adaptive launch time and an adaptive stop time; and
instruct the full speed range adaptive cruise control system to automatically launch the vehicle from the stop at the intersection based on the adaptive launch time.
 
15. A method for determining an adaptive launch time for a vehicle that stops at an intersection by a full speed range adaptive cruise control system, the method comprising:
receiving, by one or more controllers, localization data and situational data related to the vehicle;
determining, based on the localization data and the situational data, that the vehicle is approaching an intersection and will come to a stop at the intersection, wherein the vehicle is part of a queue including one or more surrounding vehicles;
in response to determining the vehicle is approaching and will come to a stop at the intersection, determining a position of the vehicle within the queue and an overall length of the queue;
calculating, by the one or more controllers, an adaptive launch time based on at least the position of the vehicle within the queue, the overall length of the queue, the situational data, and a timing delay associated with the queue, wherein the adaptive launch time indicates when the full speed range adaptive cruise control system instructs the vehicle to resume driving after stopping at the intersection, and wherein an engine start time and an engine stop time of an engine start-stop system are both a function of the adaptive launch time and an adaptive stop time; and
instructing, by the one or more controllers, the full speed range adaptive cruise control system to automatically launch the vehicle from the stop at the intersection based on the adaptive launch time.
