ELECTRIC TRAIN CAR CONTROL DEVICE Russian patent published in 2011 - IPC B60L15/20 B60L9/16 

FIELD: transport.

SUBSTANCE: set of invention relates to electric train car control devices for drive wheel induction motor inverter control. Proposed device comprises control unit including first estimation unit connected with limitation unit, second estimation unit connected with output signal processing unit. Besides, control unit comprises switching unit connected with first and second estimation units, and process control unit connected with second estimation unit and output signal processing unit. Control unit generates magnitudes of instruction of target torque for multiple motors to kill drive wheel slippage state proceeding from drive wheel motor rpm. Estimation unit defines drive wheel slippage state proceeding from deviation of speed and acceleration from preset thresholds. Limitation unit limits decrease in magnitude of instruction of preset torque fed from outside in compliance with the result of estimation made by first estimation unit. Second estimation unit defines is axial speed acceleration exceeds first threshold magnitude. Output signal processing unit outputs torque instruction magnitude processed by limitation unit.

EFFECT: improved car controllability.
