MULTIPLE-MOTOR ELECTRIC CARRIER AND METHOD OF ITS CONTROL (VERSIONS) Russian patent published in 2014 - IPC B60L11/00 H02P5/74 

FIELD: transport.

SUBSTANCE: set of invention relates to automotive industry. Proposed carrier comprises power regenerator, motion speed and moment setter, braking moment setter, motion mode selector, motors, inverter, top level control system (TLCS), consumed current transducers of inverters and load distribution system (LDS). LDS outputs are connected to outputs of inverters and current transducers. Signals of setting the factors of load distribution between drive wheels are fed to LDS inputs. LDS outputs are connected to inputs of inverter speed setting. In compliance with first version, control method consists in determination of load mean current and drive actual current departure magnitude, generation of speed setting correction signal to set required distribution of torques at drive wheels via communication link proceeding from obtained drive current departure magnitude. In compliance with second version, control method consists in determination of load mean current and drive actual current departure magnitude, generation of speed setting correction signal to set required distribution of torques at drive wheels via communication link proceeding from obtained drive current departure magnitude.

EFFECT: better operating performances.
