ELECTRIC MOTOR CONTROL METHOD AND DEVICE FOR ELECTRICALLY DRIVEN VEHICLE Russian patent published in 2020 - IPC B60L15/20 B60L7/14 B60L50/51 

FIELD: transportation.

SUBSTANCE: group of inventions relates to the control of the traction system of vehicles with electric traction. Method of electric motor control for vehicle with electric drive consists in the following. Target torque value is calculated, with which motor is instructed to output braking/driving torque, which corresponds to accelerator pedal actuation value. Disturbing torque acting on the motor is evaluated as the resistance corresponding to the road surface gradient. Correction is performed to remove disturbing torque from target torque value. Motor is controlled in accordance with the target torque value subjected to correction. Correction value in downstream roadway is reduced only when accelerator pedal deactivation value is less than preset value and vehicle speed exceeds preset speed of vehicle. Also disclosed is electric motor control device for electrically driven vehicle.

EFFECT: technical result consists in improvement of comfort of vehicle with electric drive control.
