Example Embodiment
[0028] The automatic train braking control method provided by the present invention includes:
[0029] 1) Calculate the emergency train braking trigger curve, referred to as the EB trigger curve;
[0030] The first stage is the runaway acceleration stage. figure 1 Phase A and Phase B are shown;
[0031] a 1 =a run –a grade ;
[0032] d 1 =v x ×t 1 +(a 1 ×t 1 2 / 2);
[0033] v 1 =v x +a 1 ×t 1 ;
[0034] The second stage is the idle stage, figure 1 Phase C and Phase D are shown;
[0035] a 2 =-a grade ;
[0036] d 2 =v 1 ×t 2 +(a 2 ×t 2 2 / 2);
[0037] v 2 =v 1 +a 2 ×t 2 ;
[0038] The third stage is the EB braking stage (including figure 1 Middle E stage)
[0039] a 3 =-a gebr -a grade ;
[0040] d3 =v 2 ×v 2 / (2×a 3 );
[0041] The meanings of the above parameters are as follows:
[0042] a run , the most unfavorable runaway acceleration of the train;
[0043] a grade , the most unfavorable slope of the current position;
[0044...
