REAL-TIME DIAGNOSIS METHOD OF PBR TYPE ACTUATOR

摘要

PURPOSE: A PBR actuator real-time method is provided to detect exact error by diagnosing the PBR motor actuator on a real time basis. CONSTITUTION: The PBR value of an actuator is read(S10). Whether the actuator is in an open state or a short-circuiting state is determined by comparing the PBR value with a fixed standard value(S20,S40). In case the PBR value is higher than first regular voltage, the actuator is determined as the open state(S30). In case the PBR value is lower than second regular voltage, the actuator is determined as the short-circuiting state(S50). In case the current PBR value and the previous PBR value are different, a timer is operated(S70).
