VEHICLE ELECTRICALLY DRIVEN CONTROLLER Russian patent published in 2019 - IPC B60L15/00 H02P21/05 H02P23/04 H02P29/50 

FIELD: machine building.

SUBSTANCE: present invention relates to a vehicle electrically driven controller. At that, controller is installed in vehicle with electric drive, which includes motor for movement, inverter, which drives motor, and electricity accumulation device, which exchanges electricity with motor through inverter, wherein the controller comprises an electronic control unit configured to perform switching control on the inverter switching element by switching between control with pulse-width modulation and control with a rectangular signal according to a modulation ratio, wherein electronic control unit is configured to perform control switching by control with rectangular signal in first switching mode when motor rotation speed is equal to or higher than first predetermined rotation speed, electronic control unit is configured to perform switching control by means of control with a rectangular signal in the second switching mode when the motor rotation speed is lower than the first predetermined rotation speed, first predetermined rotation speed is the rotation speed below the first resonance region, the first switching mode is the switching sequence mode, which suppresses the LC resonance in the first resonance region, and the second switching mode is a switching sequence mode which suppresses the LC resonance in the second resonance region below the first predetermined rotation speed.

EFFECT: this allows to suppress not only resonance due to low-frequency frequency component for electric motor driving, but also resonance due to its high-frequency frequency component.
