    • A method and apparatus for controlling a focus servo of an optical disk drive is provided. The focus servo controlling method includes the operations of, when an operating mode enters into a focus pull-in mode, detecting a period of time that satisfies a first threshold condition, the first threshold condition set to determine a duration in which a focal point of an optical signal emitted from a pickup is passing through a cover layer of a disk, the determination made by using a first signal proportional to a detected portion of an optical signal reflected by the disk, and preventing focus servo control from being performed during a detected period of time that first satisfies the first threshold condition since the operating mode entered into the focus pull-in mode.
    • 提供一种用于控制光盘驱动器的聚焦伺服的方法和装置。 聚焦伺服控制方法包括当操作模式进入聚焦拉入模式时检测满足第一阈值条件的时间段的操作,所述第一阈值条件被设置为确定焦点拉入模式的焦点的持续时间 从拾取器发射的光信号通过盘的覆盖层,通过使用与由盘反射的光信号的检测部分成比例的第一信号进行确定,并且防止在检测到的聚焦伺服控制期间执行聚焦伺服控制 从操作模式进入焦点拉入模式起首先满足第一阈值条件的时间段。

    • A shifting system is provided which comprises a transmission, a driver interface, and an inhibitor switch actuating module. The transmission is configured to receive a rotational force and to realize a predetermined shifting ratio, and it has an inhibitor switch. The driver interface module generates a target shift range signal corresponding to a shift range that is selected by a driver. The inhibitor switch actuating module is connected through a real-time communication bus to the driver interface module, and it actuates the inhibitor switch based on a current inhibitor switch position and the target shift range signal input from the driver interface module.
    • 提供了一种变速系统,其包括变速器,驱动器接口和抑制开关致动模块。 变速器被配置为接收旋转力并实现预定的换档比,并且其具有抑制开关。 驱动器接口模块生成与由驾驶员选择的移动范围对应的目标偏移范围信号。 抑制开关驱动模块通过实时通信总线连接到驱动器接口模块,并且基于当前抑制开关位置和从驱动器接口模块输入的目标移位范围信号来驱动抑制开关。
