Abstract
A method for displaying secondary signal devices for a driver of a railway vehicle during a journey by a railway vehicle. From a current vehicle position of the railway vehicle and an already known signal position of a secondary signal device, an actual distance of the railway vehicle in relation to the secondary signal device is determined. In the case that the actual distance is not reached in respect of a predefined current warning distance of the railway vehicle relative to the secondary signal device, a proximity of the railway vehicle relative to the secondary signal device is displayed to the driver.
Claims13
A method of displaying secondary signal devices for a driver of a railway vehicle during a journey of the railway vehicle, the method comprising:
- ascertaining a current vehicle position of the railway vehicle and determining an actual distance of the railway vehicle relative to a secondary signal device from the current vehicle position and a known signal position of the secondary signal device, and using a speed and/or average speed of the railway vehicle likely traveled in a determined future period of time for determining the actual distance of the railway vehicle from the secondary signal device;
- and
- if the actual distance undershoots a predetermined actual warning distance of the railway vehicle from the secondary signal device, displaying to a driver of the railway vehicle a proximity of the railway vehicle relative to the secondary signal device, wherein the actual warning distance is a predetermined temporal actual warning distance representing a predetermined period required by the railway vehicle for a length of track still to be traveled to the secondary signal device;
- wherein the secondary signal device ought to be observed by the driver, whereas a primary, safety-relevant and prioritized signal device must be observed by the driver;
- and
- during a journey of the railway vehicle, selecting the secondary signal devices according to a type and/or a location of the secondary signal devices.
