The invention relates to a method for adaptively controlling a vehicle speed (vFzg) in a vehicle (100), in particular a utility vehicle having a
speed control system (200), comprising at least the following steps: determining a reference speed (vRef); actuating an engine (7) and / or brakes (6) and / or a transmission (8) of the vehicle (100) via the
speed control system (200) in accordance with a target vehicle speed and / or a target vehicle deceleration in order to adapt the current vehicle speed (vFzg) to the reference speed in a fuel-efficient manner. According to the invention, the target vehicle speed and / or the target vehicle deceleration is determined for a current driving dynamic situation of the vehicle (100), defined by driving
dynamic vehicle parameters (vFzg, M, A, B, P), in accordance with at least one calculation coefficient (W, X, Y, Z), wherein the at least one calculation coefficient (W, X, Y, Z) is provided by an external processor (10) outside of the vehicle (100) in accordance with the current driving
dynamic vehicle parameters (vFzg, M, A, B, P), and in accordance with current
route information (I) for a
route section ahead, wherein the
route section ahead is established on the basis of the current driving
dynamic vehicle parameters (vFzg, M, A, B, P).
