Method for influencing railbound vehicles - wherein a track-side device (6; 106) determines a specification (v i o; Δv i) regarding a speed to be travelled by a vehicle (F i) in question, taking account of the current location (O i a) of the vehicle (F i) in question and taking account of at least one current variable (v i a, I i a), which characterises the status of the vehicle (F i) in question, - wherein a signal (S i o) for controlling the vehicle (F i) in question containing at least the specification (v i o; Δv i) regarding the speed to be travelled is transmitted by the track-side device (6; 106) to the vehicle (F i) in question, and - wherein the vehicle (F i) in question sets its speed (v i) according to the specification (v i o; Δv i) received with the signal (S i o), characterised in that - a track-side sensor arrangement acquires data (Ds.O i a, Ds.v i a, Ds.I i a) for determining the current location (O i a) and the at least one current variable (v i a, I i a) of the vehicle in question and outputs it to the track-side device (6; 106), - a vehicle-side sensor arrangement acquires, in a manner redundant to the track-side sensor arrangement, data (Df.O i a, Df.v i a, Df.I i a, Ds.O i a, Ds.v i a, Ds.I i a) for determining the current location (O i a) and the at least one current variable (v i a, I i a) of the vehicle (F i) in question and outputs it to the track-side device (6; 106), and - the track-side device (6; 106) outputs the signal (S i o) for controlling the vehicle (F i) in question as a function of a verification of the data (Ds.O i a, Ds.v i a, Ds.I i a) acquired on the track side, by means of the data (Df.O i a, Df.v i a, Df.I i a) acquired on the vehicle side, - wherein, on verification of the data (Ds.O i a, Ds.v i a, Ds.I i a) acquired on the track side by means of the data (Df.O i a, Df.v i a, Df.I i a) acquired on the vehicle side, the signal (S i o) for controlling the vehicle (F i) in question is determined as a function of the data (Ds.O i a, Ds.v i a, Ds.I i a) acquired on the track side. - wherein a track-side device (6; 106) determines a specification (v i o; Δv i) regarding a speed to be travelled by a vehicle (F i) in question, taking account of the current location (O i a) of the vehicle (F i) in question and taking account of at least one current variable (v i a, I i a), which characterises the status of the vehicle (F i) in question, - wherein a signal (S i o) for controlling the vehicle (F i) in question containing at least the specification (v i o; Δv i) regarding the speed to be travelled is transmitted by the track-side device (6; 106) to the vehicle (F i) in question, and - wherein the vehicle (F i) in question sets its speed (v i) according to the specification (v i o; Δv i) received with the signal (S i o), characterised in that - a track-side sensor arrangement acquires data (Ds.O i a, Ds.v i a, Ds.I i a) for determining the current location (O i a) and the at least one current variable (v i a, I i a) of the vehicle in question and outputs it to the track-side device (6; 106), - a vehicle-side sensor arrangement acquires, in a manner redundant to the track-side sensor arrangement, data (Df.O i a, Df.v i a, Df.I i a, Ds.O i a, Ds.v i a, Ds.I i a) for determining the current location (O i a) and the at least one current variable (v i a, I i a) of the vehicle (F i) in question and outputs it to the track-side device (6; 106), and - the track-side device (6; 106) outputs the signal (S i o) for controlling the vehicle (F i) in question as a function of a verification of the data (Ds.O i a, Ds.v i a, Ds.I i a) acquired on the track side, by means of the data (Df.O i a, Df.v i a, Df.I i a) acquired on the vehicle side, - wherein, on verification of the data (Ds.O i a, Ds.v i a, Ds.I i a) acquired on the track side by means of the data (Df.O i a, Df.v i a, Df.I i a) acquired on the vehicle side, the signal (S i o) for controlling the vehicle (F i) in question is determined as a function of the data (Ds.O i a, Ds.v i a, Ds.I i a) acquired on the track side.
