[0031] Embodiment 1
[0032] figure 2 An embodiment of the anti-skid control method for rail vehicles is shown. The electronic brake control unit 100 uniformly calculates the degree of wheel slip, and reduces the slip by adjusting the electric brake and the air brake.
[0033] The electronic brake control unit 100 calculates the rotation speed and deceleration of each wheel according to the frequency signals 16D, 17D, 18D, 19D of each wheel rotation sent by the bogie units 400 and 500, and judges the speed of a certain wheel and the maximum speed of the four wheels When the difference exceeds a certain threshold (such as 10-20km / h) or the deceleration of a certain wheel exceeds a certain threshold (such as 5-15km / h / s), it will be judged that the wheel is sliding (step S1, Yes).
[0034] The electronic brake control unit judges that all wheels have not slipped (step S2, yes), and executes electric brake and air coordinated control (step S3): Figure 4 As shown, the electronic brake ...

[0039] image 3 Another embodiment of the anti-skid control method for rail vehicles is shown. The electronic brake control unit 100 uniformly calculates the degree of wheel slip, and reduces the slip by adjusting the electric brake and the air brake.
[0040] The electronic brake control unit 100 calculates the rotation speed and deceleration of each wheel according to the frequency signals 16D, 17D, 18D, 19D of each wheel rotation sent by the bogie units 400 and 500, and judges the speed of a certain wheel and the maximum speed of the four wheels When the phase difference exceeds a certain threshold or the deceleration of a certain wheel exceeds a certain threshold, it is determined that the wheel is slipping (step S5, Yes).
[0041] The electronic brake control unit 100 preferentially executes the electric brake control (step S6): Figure 4 As shown, the electric brake control unit 100 reduces the corresponding electric brake according to the amount of coast...
