PURPOSE: A planetary gear input speed calculating method of a hybrid vehicle is provided to reduce manufacturing costs of a hybrid vehicle and to simplify design of a vehicle by calculating a planetary gear input speed without a planetary gear input speed sensor. CONSTITUTION: A rotating speed of first and second motors connected to a planetary gear unit is received from an ECU(Electronic Control Unit)(10). A planetary gear input speed inputted to a driving shaft of a vehicle is calculated based on rotation speed of the first and second motors through the planetary gear unit(20). The planetary gear input speed is inputted to the ECU(30). [Reference numerals] (11) Information is received; (12) Is the received information normal?; (13) Information error is alarmed; (20) A planetary gear input speed inputted is calculated; (30) Electronic control unit input; (40) Engine speed filtering; (50) Engine clutch combination OK ? in transmission ?; (AA) Start; (BB) End |
