Railway vehicle operation-control system and a railway vehicle using the operation control system

A railway vehicle operation-control system including at least one central processing unit connected to a plurality of devices, which are connected in parallel, via information communication means;

• said plurality of said devices having at least one operational state-monitoring function which transmits information on an operational state of each device to said the central processing unit;
• wherein a total controlled-variable necessary for said system is attained by substantially equally allocating said total control variable to said respective devices based on operational states determined from results of monitoring performed by said their operational state-monitoring functions, and a performance margin which is defined as a difference between a permissible power-output value and a current power-output value for each device;
• so that it is possible to implement said allocating of said total control variable to each device while monitoring and reflecting said performance margin of each device.
