ELECTRIC VEHICLE ELECTRIC MOTOR CONTROL METHOD AND DEVICE Russian patent published in 2020 - IPC B60L15/20 B60L50/60 H02P21/18 H02P5/46 

FIELD: transportation.

SUBSTANCE: group of inventions relates to electrical traction systems of vehicles. Electric vehicle electric motor control method consists in the following. First torque command value is calculated and angular rotation speed of first electric motor is detected. Angular rotation speed of the first electric motor is evaluated on the basis of the first value of the torque command using the vehicle model Gp(s). Second torque command value is calculated from deviation between detected and estimated angular rotation speed of first electric motor using filter H(s)/Gp(s). Torque of the first electric motor is controlled in accordance with the first value of the final torque command obtained by adding the first and second values of the torque command. Corrected torque input for second driving wheel, different from first driving wheel, is estimated value of angular rotation speed of first electric motor based on torque. Also disclosed is vehicle electric motor control device.

EFFECT: technical result consists in possibility of suppressing torsional vibration of drive shaft of front and rear driving wheels.
