| 摘要 |
The invention is based on a system for changing a signal representing rotational motion in a motor vehicle with first means for generating a first signal representing the rotational motion and a second means for generating at least one second signal representing additional information (direction of rotation, air gap, and/or brake lining wear). In addition, a third means is provided, by means of which the first signal (rotational speed signal) can be changed as a function of the second signal (direction of rotation, air gap, and/or brake lining wear). The essence of the invention is that the first means is designed in such a way that the first signal (rotational speed signal) assumes at least two first current values and/or two first voltage values. In addition, the third means is designed in accordance with the invention in such a way that, to change the first signal (rotational speed signal), at least one of the first current values and/or voltage values can be changed at least for a certain period of time into at least one second current value and/or voltage value as a function of the second signal (direction or rotation, air gap and/or brake lining wear).
