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

FIELD: machine building.

SUBSTANCE: group of inventions relates to control of electric traction systems of vehicles. 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 based on estimated value of disturbing torque so that resistance component is suppressed. It is determined whether operating value of accelerator pedal depressing or equivalent of intermediate state. Correction value is reduced, at least, or when operating value of accelerator pedal depression exceeds equivalent of intermediate state on road running under, or when operating value of accelerator pedal depression is less than equivalent of intermediate state on road going into ascent. Also disclosed is electric motor control device of electric vehicle.

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