Claim 0:
1. A method for monitoring a position of a vehicle parked on a track, the method which comprises:
providing the vehicle with a vehicle-side device of an automatic train safety system, and fully powering down the vehicle including deactivating the vehicle-side device when the vehicle is parked;
prior to deactivating the vehicle-side device, determining a first positional value from the position of the vehicle by the automatic train safety system and, independently thereof, externally determining a second positional value by a further localization system;
assigning the second positional value to the vehicle;
in a deactivated state of the vehicle-side device, monitoring an actual position of the vehicle by the further localization system and externally determining further positional values, thereby using the second positional value as a target position of the vehicle;
transmitting at least one of the further positional values or a deviation of the actual position from the target position to a trackside device of the train safety system; and
following an activation of the vehicle-side device, transmitting a positional value representing the actual position of the vehicle from the trackside device to the vehicle-side device;
wherein if a result of the monitoring of the actual position is that the vehicle has not moved, the first positional value is transmitted as the positional value; and
wherein if the result of the monitoring of the actual position is that the vehicle has moved, a most recent one of the at least one of the further positional values is transmitted as the positional value.
