METHOD FOR CONTROLLING A PARKING BRAKE SYSTEM

摘要

A method that includes steps of measuring voltage and current of the parking brake system during creation of a parking brake apply or release of the parking brake apply. The method includes estimating motor position, motor speed, and a current draw of the motor using the measured voltage and the measured current. The method includes estimating a parking brake force with the estimated motor position. The method includes correcting the estimated motor position, motor speed, and the current draw of the motor with the measured current, and/or correcting the estimated parking brake force with the corrected estimated motor position, corrected motor, and the corrected current draw of the motor. The method includes determining the creation of the parking brake apply with the corrected parking brake force and/or determining release of the parking brake apply with the corrected estimated motor position.

1) A method of controlling a parking brake system, the method comprising:
measuring voltage of the parking brake system during creation of a parking brake apply or release of the parking brake apply; measuring current of the parking brake system during the creation of the parking brake apply or the release of the parking brake apply; estimating a position of a motor, estimating a speed of the motor, and estimating a current draw of the motor from a source using the measured voltage and the measured current; estimating a parking brake force with the estimated position of the motor; correcting the estimated position of the motor with the measured current, correcting the estimated speed of the motor with the measured current, and correcting the estimated current draw of the motor with the measured current, and/or correcting the estimated parking brake force with the corrected estimated position of the motor, the corrected speed of the motor, and the corrected current draw of the motor; and determining the creation of the parking brake apply with the corrected parking brake force and/or determining the release of the parking brake apply with the corrected estimated position of the motor.
