- the front sliding step S 1 can be extended with a sliding step drive, not shown in FIG.
- the sliding step drive of the front sliding step S1 is controlled by an associated sliding step control device SSE1, which, in the illustration according to Figure 1, evaluates the sensor signal from a front distance sensor AS1 and selects the extension W1 of the front sliding step S1 in such a way that its distance from the platform edge 21 is in a predetermined target range.
- SSE1 sliding step control device
- the front distance sensor AS 1 detects a vehicle platform-related distance Al, for example the distance between the front door TI and the platform edge 21, the distance between the car contour in the area of the front door TI and the platform edge 21 or the distance between the front door TI associated sliding step S 1 and the platform edge 21, and are as or. with the aid of a sensor signal, a measured front distance value M1 that indicates the detected distance Al.
