FIELD: transport.
SUBSTANCE: invention relates to vehicle control. Control network (1) for rail vehicle includes rail vehicle control devices being annularly interconnected by at least two communication channels. The first control device (SG1) transmits useful data (ND) via one communication channel in the first direction to the second control device (SG2), and associated with useful data (ND) control data (PD) for useful data (ND) checking via the other communication channel in the second direction being opposite to the first direction. Due to this, improvement of data transmission to the second control device (SG2) is achieved, as well as possibility emerges to detect data manipulation by the third parties.
EFFECT: reduced unnecessary creation of electromagnetic fields and increased safety of system for transmitting electric energy to vehicle.
