ABSTRACT OF THE DISCLOSURE The speed of a vehicle is controlled in response to a new speed command lower than a previous speed command such that a safe brake speed profile reference is provided for increasing the average speed of the train in relation to the new speed command and before the new speed command controls the vehicle speed. A sensed vehicle acceleration is compared with a known safe acceleration to determine a speed error and a distance error to establish a critical velocity for the vehicle, which is used to provide an open loop brake control to merge the train speed in relation to a provided safe brake profile before the vehicle speed can again be controlled in relation to the new speed command.
