1. A method for controlling brake pressure during a shift of a vehicle out of park, the method comprising:
determining that a first status condition is met when the vehicle is in park with an electric parking brake applied;
determining that a second status condition is met when the vehicle is not moving;
responsive to detecting a shift of the vehicle out of park when the first and second status conditions are both met, directing a build-up of brake pressure until a brake pressure target is reached; and
holding the brake pressure at the brake pressure target until a release condition is met,
wherein the release condition comprises elapse of a predetermined period of time to enable handover to a hill start assist function.
