Claims (20)

1. 1. A method (1000) for implementing a brake particle collection system (20) for a disc brake, wherein the collection system comprises a particle suction means (22, 24, 26) controlled by a control unit (30), wherein the method includes the steps of:
2. monitor (1100) the rotation speed of the disk (4); and
3. activate (1200) a non-zero level (pb) of suction if the rotation speed of the disk is substantially constant and has a non-zero value.
4. 2. The method according to claim 1, wherein the activation of the suction level (pb) depends on whether the brake exhibits a residual braking torque that exceeds a threshold value (Cc).
5. 3. The method according to claim 2, in which the residual braking torque of the brake is pre-set (1300) by calibration on a brake dynamometer or on a roller test bench.
6. 4. The method of claim 2, wherein the residual braking torque is determined by identifying the existing disc/pad/caliper trio and accessing a database that lists the residual torques of several such trios.
7. 5. The method according to claim 2, wherein the residual braking torque is measured during operation.
8. 6. The method according to any one of paragraphs 2-5, in which the non-zero suction level (pb) is proportional to the residual braking torque (Cb).
9. 7. The method according to any one of paragraphs 2-6, in which the threshold value (Cc) is from 1 N⋅m to 10 N⋅m.
10. 8. The method according to any one of paragraphs 1-7, in which the suction level is proportional to the rotation speed of the disk.
11. 9. The method according to any one of claims 1 to 8, wherein the activation of the suction level (pb) depends on the disk exceeding a threshold rotation speed.
12. 10. A brake particle collection system (20) for collecting brake particles ejected by a disc brake (2), wherein the collection system (20) comprises:
13. means (22, 24, 26) for suctioning particles, in which the suction level can be adjusted;
14. a control unit (30) configured to control the suction level of the suction means (22, 24, 26) in accordance with the method according to any one of paragraphs 1-9.
15. 11. A motor vehicle or a railway vehicle (1) containing:
16. disc brake (2); and
17. a brake particle collection system (20) for collecting brake particles ejected by a disc brake (2), wherein the collection system (20) comprises:
18. means (22, 24, 26) for suctioning particles; and
19. a control unit (30) regulating the state of the suction means (22, 24, 26),
20. wherein the vehicle is characterized in that the control unit (30) is configured to activate a non-zero level (pb) of suction of the suction means (22, 24, 26) when the vehicle (1) maintains cruising speed.
