    • 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.
    • 混合动力车辆的油泵控制单元的故障安全控制方法通过硬线直接连接自动变速器控制单元和油泵控制单元,以在CAN通信线路发生故障的情况下控制油泵驱动器 的油泵控制。 通过自动变速器控制单元,能够通过电动机控制单元(MCU)或低速制动器(UD_BRAKE)来控制电动油泵的电动机的转速,以控制在开/关模式或滑动模式,直到 在油泵控制单元或电动油泵发生故障的情况下,机械油泵被驱动。
