Title:
BRAKING TEMPERATURE CONTROL METHOD AND SYSTEM FOR ELECTROMECHANICAL BRAKE
Document Type and Number:
WIPO Patent Application WO/2024/066222
Kind Code:
A1
Abstract:
The present invention relates to a braking temperature control method and system for an electromechanical brake. According to the braking temperature control method for the electromechanical brake (EMB) provided by the present invention, an intermediate temperature is obtained on the basis of a temperature obtained by a thermistor mounted on a stator winding, and a braking temperature control scheme is generated according to the relationship between the intermediate temperature and a preset temperature, so as to control the heating of a drive motor of the EMB. Therefore, under a conventional temperature control strategy, the working environment of the drive motor in the EMB can be effectively improved, thus ensuring the braking efficiency of the EMB. Moreover, in a high-temperature abnormal working state of the drive motor in the EMB, the working temperature of the drive motor can be effectively controlled by means of a braking force redistribution strategy, thus preventing braking failure caused by the overheating of the motor.
