VEHICLE Russian patent published in 2018 - IPC B60L11/18 H02P6/08 H02P6/15 

FIELD: electricity; transportation.

SUBSTANCE: invention relates to the field of the electric traction vehicle control. Vehicle performs the first PWM control to generate the first PWM signal for plurality of switching elements, to switch plurality of switching elements by the phases voltage commands comparison with the carrier frequency voltage based on the torque command. At that, including the rotational speed and the motor torque commands target operating point is outside the predetermined range. Vehicle performs the second PWM control to generate the second PWM signal for plurality of switching elements in order to switch plurality of switching elements based on the voltage modulation factor, as well as the phase voltage based on the torque control command and number of pulses at the predetermined electric motor electric angle period, or the first PWM control when the target operating point is within the predetermined region.

EFFECT: enabling reduction in the electric energy losses.
