1. A method for preconditioning at least a part of an engine system of a vehicle, the engine system comprising an engine and an exhaust aftertreatment system, EATS, the method comprising:
providing predicted vehicle operational information comprising a vehicle operational initialization time and predicted engine operation,
determining whether or not estimated cold-start emissions of the predicted engine operation achieves a threshold criterium,
in response to achieving the threshold criterium, preconditioning at least a part of the engine system such that at least said part of the engine system is preconditioned at a time of the vehicle operational initialization time,
wherein determining whether or not the estimated cold-start emissions of the predicted engine operation achieves the threshold criterium comprises comparing the estimated cold-start emissions associated with predicted engine operation with and without preconditioning of at least said part of the engine system, and wherein the threshold criterium is a reduced estimated cold-start emission of the predicted engine operation with preconditioning of at least said part of the engine system; wherein the predicted vehicle operational information further comprises preview information of the vehicle operation including at least an upcoming road event, wherein the predicted engine operation comprises predicted engine speed and/or predicted engine torque in response to the upcoming road event, and wherein the estimated cold-start emissions of the predicted engine operation is based on the estimated cold-start emissions associated with the predicted engine speed and/or predicted engine torque.
