Control device, control system, railway vehicle and associated control method

A control device for at least two traction engines of a rail vehicle, the control device comprising:

• an estimation module configured to estimate a traction power requirement of the rail vehicle as a function of at least one position signal of the rail vehicle;
• a determination module configured to determine a required operating state of each engine based on the power requirement;
• an adaptation module configured to determine, from the required operating state of each engine, an adapted operating state of said engine as a function of at least one specific parameter relating to the operation of the rail vehicle;
• and
• a transmitter module configured to transmit a control signal to each engine, the control signal comprising a command of the adapted operating state of each engine received from the adaptation module, the command of the adapted operating state being configured to control the operation of each engine in the adapted operating state of said engine,
• wherein the estimating module is configured to receive statistical data of the power requirement as a function of the position of the rail vehicle and configured to estimate the power requirement additionally as a function of the statistical data.
