Abstract: PURPOSE: An inverter fail detecting method for electric and hybrid vehicles is provided to prevent damage to parts caused by excessive current and short circuit through accurate detection of a fail. CONSTITUTION: A current sensor senses current applied from an inverter to a drive motor(S1). A comparator compares the sensed current with a reference value and detects a fail in a hardware manner(S11-S16). A CPU detects a fail using sensed current and a reference value set on software(S21-S26). The hardware and software fail detection processes are implemented at the same time. If the CPU detects a fail during one of the hardware and software fail detection processes, a fail of the inverter is finally determined.

Abstract: PURPOSE: A method for compensating an abnormal output of a resolver of an environment-friendly vehicle is provided to secure reliability for drivability of an electric vehicle and a hybrid function, by compensating current motor rotor position accurately, when the motor rotor position information is omitted. CONSTITUTION: A motor current position angle for compensation is obtained, by setting a motor current position angle before compensation as a current motor position angle(S101). Motor position displacement amount between previous sampling and current sampling according to RDC output is obtained, and motor position displacement amount between the previous sampling and previous sampling before the previous sampling is obtained at the same time(S102). A variable(A) is calculated(S103). The variable is expressed as a difference between the position displacement amount of the current sampling and the previous sampling and the position displacement amount of the previous sampling and the previous sampling before the previous sampling. It is determined whether to compensate or not, by comparing with the calculated variable compensation variable(S104). A motor current position value for compensation is calculated(S105). The omitted motor rotor position information is compensated by the calculated motor current position angle for compensation(S106). [Reference numerals] (AA) Start; (BB) End
