ELECTRIC VEHICLE MOTOR CONTROL METHOD Russian patent published in 2024 - IPC B60L15/20 

FIELD: vehicles.

SUBSTANCE: invention relates to a method of controlling an electric motor of an electric vehicle. Method involves real-time monitoring of the current and temperature of the engine control unit and making a decision on changing the operating mode depending on the value of the monitored parameters. Method includes torque control levels. At the first level, the state of the electric motor is determined as safe, when the torque reaches the pre-set lower threshold value of the torque. At the second level, the current actual value of the electric motor torque is determined and compared with the required value of the electric motor torque. At the third level, motor control unit voltage, current and temperature are monitored. If the state of the electric motor is not defined as safe, the torque of the electric motor is controlled so as to provide a safe state. If the safe state of the electric motor is not achieved within the specified time, the engine control unit sends an error message and a command to stop the electric motor to the electric vehicle control unit.

EFFECT: improving the safety of electric vehicles.
