摘要
A fail-safe control method for an oil pump control unit of a hybrid vehicle directly connects an automatic transmission control unit and an oil pump control unit via a hard wire to control an oil pump driver in the event of a failure of the CAN communication line of the oil pump control. It enables the rotation speed of a motor of the electric oil pump to be controlled by a motor control unit (MCU) or a underdrive brake (UD_BRAKE) to be controlled in on/off mode or in slip mode by the automatic transmission control unit until a mechanical oil pump is driven, in the event of a failure of the oil pump control unit or the electric oil pump.
