Abstract
An apparatus and method for controlling train speed are disclosed, the method including receiving an operation data, estimating a future train speed subsequent to a predetermined time of the train, using the operation data and dynamics model of a train, calculating a TTSLC {Time-To-Speed-Limit Crossing, a time when the train exceeds an ATP (Automatic Train Protection) speed limit}, and outputting a deceleration command by determining an additional braking force, in a case the TTSLC is smaller than a predetermined threshold.
Claims14
An apparatus for controlling train speed, the apparatus comprising:
- an estimation unit estimating a future speed subsequent to a predetermined time of the train, using an operation data and a dynamics model of the train;
- a calculation unit calculating a TTSLC {Time-To-Speed-Limit Crossing, a time when the train exceeds an ATP (Automatic Train Protection) speed limit}, using the future speed from the estimation unit;
- and a first controller outputting a deceleration command by determining an additional braking force, in a case the TTSLC is smaller than a predetermined threshold.
