发明名称 Method and system for diagnosing charging state
摘要 A method for diagnosing charging state may include a diagnostic trouble code generation step of generating a diagnostic trouble code (DTC) when the state for charging a battery from an alternator is abnormal in the state in which the alternator is operating to charge the battery while a vehicle is traveling, and then storing diagnostic trouble code in an ECU (Electronic Control Unit), and a diagnostic trouble code release step of deleting the diagnostic trouble code in the ECU when the state for charging the battery from the alternator is returned to be normal.

主权项 1. A method for diagnosing charging state comprising: a diagnostic trouble code generation step of generating a diagnostic trouble code (DTC) when the state for charging a battery from an alternator is abnormal in the state in which the alternator is operating to charge the battery while a vehicle is traveling, and then storing diagnostic trouble code in an ECU (Electronic Control Unit), wherein the vehicle is a vehicle having an internal combustion engine; and a diagnostic trouble code release step of deleting the diagnostic trouble code in the ECU when the state for charging the battery from the alternator is returned to be normal, wherein the diagnostic trouble code generation step comprises: a diagnostic trouble code generation entry determination step of determining whether the conditions for generating diagnostic trouble code are satisfied by determining the states of the vehicle and the battery;a charging state detection step of detecting the state charged to the battery from the alternator;a charging state defect determination step of determining whether the charging state from the alternator is defective, by comparing an engine driving time, an operating conditions of the alternator, a difference between a target voltage and an output voltage and a current accumulation with each predetermined conditions; anda diagnostic trouble code store step of generating the diagnostic trouble code with the state that the battery is not charged due to a charging state defect from the alternator and storing the diagnostic trouble code in the ECU, and the charging state detection step calculated a cumulative amount of current charged from the alternator to the battery, duties of a C terminal of the alternator and a FR terminal of the alternator and an average voltage of the battery.
