1. A method for controlling oil pressure in a controllable oil pump of an internal combustion engine (ICE) system, of a vehicle, 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, wherein determining the expected change in the operation of the ICE system for an upcoming vehicle operating situation is determined based on route information describing at least a route segment from a starting point to an end point, and wherein determining the expected change in the operation of the ICE system is determined based on a previous ICE operating profile for the route segment;
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.
