Method for diagnosing and controlling an unusual hydraulic state of hybrid vehicle transmission
Abstract:
A system and method for diagnosing and controlling an unusual hydraulic state of an electric variable transmission of a hybrid vehicle achieving multi modes including a first mode and a second mode, the method may include determining whether the first mode is converted into the second mode, determining whether a hydraulic pressure is generated in a clutch which is engaged and the generated hydraulic pressure is higher than a predetermined hydraulic pressure when the first mode is converted into the second mode, and determining that the hybrid vehicle is in an unusual condition if the hydraulic pressure is not generated in the clutch or the generated hydraulic pressure is higher than the predetermined hydraulic pressure.
