A method for predicting vehicle speed in a braking control system for wheeled vehicles, where a signal representing wheel speed before braking is used to trigger charging of a capacitor in an electronic unit. The capacitor voltage is reduced during braking in response to a predetermined retardation value in order to correspond to an instantaneous value for the vehicle speed. The vehicle speed signal is compared with a wheel speed signal, which comparison triggers, when the wheel speed signal exceeds the vehicle speed signal, up-dating of the capacitor voltage level to a value corresponding to the actual wheel speed signal. When up-dating the vehicle speed signal, the preselected retardation value is gradually lowered by a value corresponding to the magnitude of the actual up-dating.
