  • This change of inductance L causes a bump 48 in the course of electrical current J.
  • This bump 48 is detected by the analysis module 16 in order to detect the movement of the braking means 10, 11.
  • Figure 6b shows the differentiation J 1 of the current signal J of Figure 6a with respect to time.
  • the bump 48 at time t 2 in the course of the electrical current J results in a prominent peak 49 in the differentiated signal J'.

It avoids the need for any additional mechanical parts as e.g. mechanical switches and setups thereof. As a result it is very robust, easy to assemble and reduces the need for maintenance considerably.
  • An idea of the invention is to measure the brake current time slope and to detect the movement of the braking means by the typical shape of the time transient. Due to the movement of the braking means the magnetic system characteristics i.e. inductance of the brake coil changes. This correlates with a typical dip in the brake current time slope when the brake lever or disk starts moving. This is shown in the figures and the description.
