Title:
ESTIMATION OF THE TEMPERATURE OF AN ELECTRIC MOTOR OF A VEHICLE BRAKE ACTUATOR, AND CONTROL OF THE MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/188175
Kind Code:
A3
Abstract:
Figure 3 depicts a vehicle wheel control device (4). The control device (4) is configured to determine a first corrective coefficient (α1) of temperature (T) of the motor from a ratio of an angular speed (ω) of the motor to the supply intensity (i) of the motor depending on the supply voltage (u) of the motor. The control device (4) is configured to determine a second corrective coefficient (α2) of temperature (T) of the motor from a ratio of the ohmic resistance (R) of the motor to the constant (K) of the motor depending on the temperature (T) of the motor.
