METHOD AND APPARATUS FOR DETECTING FAIL OF ELECTRONIC PARKING BRAKE

机译:检测电子驻车制动器故障的方法和装置

摘要

A method for detecting a fail of an electronic parking brake may include: detecting, by an electronic control unit (ECU), a current applied to a motor during a parking operation of an eDIH parking brake, and detecting a current inflection point at which the slope of the current is changed, the slope of the current having started to rise in a load generation section following a no-load section after a starting current of the motor was generated; and comparing, by the ECU, the current value of the detected current inflection point to a current value of a preset reference current inflection point, and recognizing that a fail occurred during the parking operation of the eDIH parking brake, when the current value of the detected current inflection point is different by a preset error range or more from the current value of the reference current inflection point.
