摘要： The present invention provides methods for preventing low train voltages and managing interference, thereby improving the efficiency, reliability, and passenger comfort associated with commuter trains. An algorithm implementing neural network technology is used to predict low voltages before they occur. Once voltages are predicted, then multiple trains can be controlled to prevent low voltage events. Further, algorithms for managing inference are presented in the present invention. Different types of interference problems are addressed in the present invention such as “Interference During Acceleration”, “Interference Near Station Stops”, and “Interference During Delay Recovery.” Managing such interference avoids unnecessary brake/acceleration cycles during acceleration, immediately before station stops, and after substantial delays. Algorithms are demonstrated to avoid oscillatory brake/acceleration cycles due to interference and to smooth the trajectories of closely following trains. This is achieved by maintaining sufficient following distances to avoid unnecessary braking/accelerating. These methods generate smooth train trajectories, making for a more comfortable ride, and improve train motor reliability by avoiding unnecessary mode-changes between propulsion and braking. These algorithms can also have a favorable impact on traction power system requirements and energy consumption.

摘要： A vehicle rollover sensing apparatus and method are provided for detecting a rollover condition of the vehicle. The rollover sensing apparatus includes an angular rate sensor for sensing attitude rate of change of a vehicle and a lateral accelerometer for sensing lateral dynamics of the vehicle. The rollover sensing apparatus also has an integrator for integrating the sensed attitude rate of change signal over a variable time window and producing an attitude angle. The rollover sensing apparatus further includes deployment logic for comparing the attitude angle and attitude rate of change to a pair of variable threshold values with a gray-zone that varies based on time, and for deploying a vehicle overturn condition signal based on the comparison. Sensitivity of the deployment logic is adjusted as a function of the sensed lateral dynamics to enhance rollover deployment during certain driving events.
