1. A method for controlling the deceleration of a vehicle, wherein the vehicle includes a central control unit, a first brake circuit (BK1) for a rear axle (HA) and a second brake circuit (BK2) for a front axle (VA); the method comprising the steps of:
in response to an electronically requested deceleration request (a) below a predetermined deceleration threshold value (a1), activating only the first brake circuit that one of the brake circuits (BK1, BK2) of the rear axle and the front axle, respectively, that permits a gradation in a change of pressure (Δp) for substantially continuous, jolt-free manipulation of the deceleration via the central control unit; and,
causing the activation of that one of the brake circuits (BK1, BK2) to be maintained as long as the predetermined deceleration threshold value (a1) is not exceeded.
