METHOD AND DEVICE FOR ELECTRIC VEHICLE ELECTRIC MOTOR CONTROL Russian patent published in 2020 - IPC B60L15/20 B60L7/18 B60L50/51 

FIELD: transportation.

SUBSTANCE: group of inventions relates to the control of the traction system of vehicles with electric traction. Electric vehicle electric motor control method consists in the following. Disturbing torque is evaluated, which acts on electric motor as a component of resistance connected with gradient. Correction is performed by means of which braking force or motive force increases and decreases in order to suppress resistance component in compliance with estimated value of disturbing torque. Reducing the value of correction of braking force or driving force on the road going under the descent, at a given or steep gradient. Calculating the upper limit value of the correction value on the basis of the torque value, which allows the vehicle to stop when the accelerator pedal depressing operating value is equal to 0 at the specified gradient. Also disclosed is electric vehicle electric motor control device.

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