FIELD: railway.
SUBSTANCE: group of inventions relates to the control of the traction system of electric vehicles. The method for controlling a railway vehicle is to determine the actual speed of the railway vehicle, determine the actual rotation speed of the wheel of the railway vehicle, obtain the estimated torque from the motor controller, estimate the maximum adhesion coefficient, determine the reference torque, and provide the reference torque to the engine controller. In this case, the maximum coefficient of adhesion is estimated based on the wheel speed, the actual speed of the railway vehicle and the calculated torque. The reference torque is determined by summing the torque calculated from the estimated adhesion coefficient and the output torque provided by the feedback control. Also claimed are a torque controller, a rail vehicle and a processor.
EFFECT: preventing the excitation of possible transmission resonance.
