Abstract
The present invention concerns a method for reducing the drive delay of a rolling stock to reach a destination, the rolling stock being driven by a driver to follow a running profile that defines the speeds and positions of the rolling stock at different timings. The method comprises the steps of: —determining a current timing, —getting a nominal acceleration of the rolling stock, the nominal acceleration being determined by the driver of the rolling stock to follow the running profile at the current timing, —determining the speed error of the rolling stock with the rolling profile, —determining the position error of the rolling stock with the rolling profile, —determining an estimate of the time to reach the destination, —determining a marginal acceleration from the speed error, the position error and the estimated time to reach the destination, —accelerating the rolling stock with the sum of nominal and determined marginal accelerations.
