Abstract

A vehicle wheel control device is configured to determine a first corrective coefficient of temperature of the motor from a ratio of an angular speed of the motor to the supply intensity of the motor depending on the supply voltage of the motor. The control device is configured to determine a second corrective coefficient of temperature of the motor from a ratio of the ohmic resistance of the motor to the constant of the motor depending on the temperature of the motor.
