Prior Art Detail
Summary / Description
| Summary / Description | The present invention is directed to a system and method for optimizing the dynamics and energy usage of long vehicles such as freight trains by determining their operating conditions and calculating an optimal sequence of power and braking control actions. The sequence calculated provides for optimal vehicle dynamic behaviour with minimum energy usage in accordance with the train type, track topography and train operation rules and policies. The method and system serves as a management tool for the driver and reference signals for a train cruise control or autopilot system |

Excerpt
Excerpt A control system for controlling the dynamics and energy consumption of long vehicles during operation includingcomputer means adapted to receive and process signals from input means to produce an operating parameter signal; and control means for receiving and responding to said operating parameter signal; wherein the processing of the input signals involves algorithmic analysis of the signals weighted in response to present and future grade forces and speed requirements to produce an initial operating signal, analysis of the input signals weighted in response to present and future track curvature and speed requirements and combining the results of both analyses to produce said operating parameter signal. |
