Abstract
A particularly flexible method for automatically calibrating a wheel sensor includes using the wheel sensor to determine that a calibration must be carried out. The wheel sensor determines a point in time suitable for carrying out the calibration and the calibration itself is carried out by the wheel sensor at the determined point in time. A wheel sensor for carrying out the method is also provided.
Claims13
A method for calibrating a wheel sensor, the method comprising the following steps:
- using the wheel sensor to establish that a decentralized calibration procedure is to be performed;
- using the wheel sensor to provide a self-acting determination of a point in time being suitable for the calibration procedure to be performed with reference to a detection that a rail-borne vehicle has completely driven past the wheel sensor by taking into consideration a temporal sequence of detecting wheels of the rail-borne vehicle;
- and
- using the wheel sensor to automatically perform a self-calibration at the determined point in time.

A vehicle, comprising:
- a wheel sensor for establishing in a decentralized manner that a calibration procedure is to be performed;
- said wheel sensor determining in a self-acting manner a point in time being suitable for the calibration procedure to be performed with reference to a detection that a rail-borne vehicle has completely driven past said wheel sensor by taking into consideration a temporal sequence of detecting wheels of the rail-borne vehicle;
- and
- said wheel sensor automatically performing a self-calibration procedure at the determined point in time.
