Abstract: PURPOSE: A method of reducing noise from a vehicle with a GDI pump is provided to reduce noise from a solenoid valve since the opening/closing frequency of the solenoid valve is controlled depending on the state of the vehicle. CONSTITUTION: A method of reducing noise from a vehicle with a GDI pump comprises the following steps. Whether or not the vehicle is in an idle state is determined depending on the operating state of the vehicle and the amount of fuel required for the engine. The number and timing of opening/closing operations of a solenoid valve in a DGI pump is controlled depending on the idle state of the vehicle. The noise of the GDI pump is controlled. If the vehicle is in an idle state, the vehicle operates in a noise reducing mode. The noise reducing mode supplies fuel by opening the solenoid valve once, while the plunger of the GDI pump reciprocates several times. If the vehicle is not in an idle state, it operates in a normal mode. The normal mode supplies fuel by opening the solenoid valve once, while the plunger of the GDI pump reciprocates once.
Abstract translation: 目的：提供一种使用GDI泵降低车辆噪音的方法，以减少电磁阀的噪音，因为根据车辆的状态控制电磁阀的开/关频率。 构成：使用GDI泵减少来自车辆的噪音的方法包括以下步骤。 根据车辆的运行状态和发动机所需的燃料量来确定车辆是否处于空转状态。 根据车辆的怠速状态来控制DGI泵中的电磁阀的打开/关闭操作的次数和时间。 控制GDI泵的噪音。 如果车辆处于空闲状态，则车辆以降噪模式运行。 降噪模式通过打开电磁阀一次提供燃料，而GDI泵的柱塞往复运动几次。 如果车辆不处于空闲状态，则其工作在正常模式。 正常模式通过打开电磁阀一次提供燃料，而GDI泵的柱塞往复运动一次。

Abstract: An ECU of a vehicle and a reprogramming method of the same are provided to prevent a calibration ID damage by storing the calibration ID for identifying the data in a RAM programming region even if there is a program error while reprogramming. If a calibration ID requirement is received form a scan tool, the calibration ID stored in a first region of a memory device is transmitted to the scan tool. When the calibration ID is confirmed, all the existing programmed data in a second region of the memory device is deleted, and the data received from the scan tool is written in the second region so as to be reprogrammed. The calibration ID stored in the second region is stored again in the first region.
