A heavy-duty vehicle has a first set of metallic brakes and a second set of non-metallic brakes having lower weight than the metallic brakes. A processor device is configured to acquire prediction data indicative of an upcoming brake event that is expected to occur along a road on which the vehicle is travelling; determine, based on the prediction data, an expected value of kinetic energy that will be absorbed during said upcoming brake event; select, based on said determined expected value of kinetic energy, which one of the first and second sets of brakes that is to be activated to absorb kinetic energy during said upcoming brake event; and control the selected set of brakes to be activated during said brake event, wherein the other set of brakes remains inactivated during said brake event.

Heavy-duty vehicle

A computer-implemented method for controlling a regeneration event for an exhaust aftertreatment system of a vehicle is described. The method comprises predicting, by a processor device, expected travelling times for travelling from a starting point to a first destination point and from an auxiliary point to a second destination point based on collected drive time statistical data and collected additional drive time statistical data; and controlling, by the processor device, the regeneration event based on the predicted expected travelling times.

Computer-implemented method for controlling a regeneration event

A method for preconditioning at least a part of an engine system of a vehicle. The engine system includes an engine and an exhaust aftertreatment system, EATS. The method providing predicted vehicle operational information comprising a vehicle operational initialization time and predicted engine operation, determining whether or not 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.

Method for preconditioning at least a part of an engine system of a vehicle

A method for controlling oil pressure in a controllable oil pump of an internal combustion engine system. A vehicle is arranged in communication with a control unit, the method comprising: receiving an indication of an upcoming vehicle operating situation affecting an operation of the ICE system; determining an expected change in the operation of the ICE system for the upcoming vehicle operating situation; determining a current oil pressure of the oil pump; and on the basis of said determined expected change in the operation of the ICE system and the determined current oil pressure of the oil pump, determining a minimum oil pressure for the oil pump for the upcoming vehicle operating situation.

An urea injection control system for an internal combustion engine, specifically adapted to apply a scheme for decreasing a NOx level downstream of a selective catalytic reduction catalyst of an ICE related exhaust gas aftertreatment system. The present disclosure also relates to a corresponding computer implemented method and a computer program product.
