FIELD: transport.
SUBSTANCE: invention relates to rail transport and may be used at rolling stock with induction traction motors supplied from solid-state static converters. Proposed method exploits external circuit of traction motor rpm control by rpm deviation controller wherein motor rpm setting reduced to linear speed on wheel rim is defined by integration by integrating setting selected from two values: a0, in traction mode, smaller by minor magnitude Δa than locomotive linear acceleration al, and a1, in traction mode exceeding by Δa more than al (the other way in braking). Besides, motor rpm internal control circuit is used with its input signal being rpm controller output signal with due allowance for torque limits. Selection between a0=al-Δa and a1=al+Δa (in traction mode) or a0=al+Δa and a1=al-Δa (in braking mode) is made in response to signals of two units: first, device rail vehicle wheel spin and skid detector to detect spin and skin by the level of oscillations Uosc in traction circuit, and, second, slippage speed absolute value controller.
EFFECT: flat-speed and oscillations control by rail holding.
