Land-side virtual windshield washer fluid level indicator

Abstract

A windshield washer fluid level monitoring device (30) for a rail vehicle is described. The windshield washer fluid level monitoring device (30) has a vehicle-side fill level sensor (1a, 1b) arranged on or in a windshield washer fluid reservoir (1) of the rail vehicle for detecting sensor data (SD). A data readout unit (32) for reading the sensor data (SD) is also part of the windshield washer fluid level monitoring device (30). The windshield washer fluid level monitoring device (30) also comprises a data transmission unit (33) for wirelessly transmitting the sensor data (SD) to a land-based data reception device. A rail vehicle is also described. Furthermore, a land-based windshield washer fluid level indicator device (40) is described. Furthermore, a system (50) for simulating a land-based virtual fill level indicator (FSD) of a rail vehicle is described.Furthermore, a method for detecting and transmitting a fill level of a washer fluid reservoir (1) of a rail vehicle is described. A method for generating a virtual fill level indicator is also described. Furthermore, a method for monitoring a fill level of a washer fluid reservoir (1) of a rail vehicle is described.

Claims
