CONTROL METHOD FOR TRACTION ELECTRIC DRIVE OF MULTIWHEEL VEHICLE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC B60L3/10 B60L11/00 H02P5/74 

FIELD: transport.

SUBSTANCE: set of inventions relates to automotive industry and may be used in traction electric drives of independent pneumatic-tired vehicles. Method of wheel propulsive force control for multiwheel all-wheel-drive vehicle consists in setting parameter preset values for traction motor regulation, measuring their rotation speeds, processing measurement results with regard to curvature of movement trajectory, and correction of set values by signals proportional to differences between electric motor speeds and their calculated maximum permissible speeds. The device comprises traction motors, voltage converters, power source, motor speed sensors, preset values generators for the first and the second regulation parameter, units for correction of preset values of the first regulation parameter, movement direction generators, unit for motor speeds adjustment to one motor, unit for selection of minimal rotation speed from adjusted motor speeds, unit for calculation of corrective signals, unit for calculation of limit values of converter voltages regulation coefficients.

EFFECT: higher electric drive efficiency.
