    • A method, system and computer program product for conserving power in a GPS-based navigation system. The navigation system receives input from the driver selecting a portion(s) of the route (route from the current location of the vehicle to the destination) where the driver requests guidance. For those portions of the route not selected by the driver to receive guidance, the navigation system implements a low detail mode of operation. In such a mode of operation, the navigation system reduces its update frequency as well as displays less detailed graphics so as to consume less power. For those portions selected by the driver to receive guidance, the navigation system implements a high detail mode of operation, where the navigation system is capable of audio-visually communicating to the driver instructions for reaching a given destination. In this manner, the power consumed by the navigation system will be more efficiently utilized.
    • 一种用于在基于GPS的导航系统中节省电力的方法,系统和计算机程序产品。 导航系统接收来自驾驶员的驾驶员的输入,该驾驶员选择路线的一部分(从车辆的当前位置到目的地的路线),驾驶员请求引导。 对于未被驾驶员选择以接收指导的路线的那些部分,导航系统实现低细节操作模式。 在这样的操作模式中,导航系统降低其更新频率,并且显示较不详细的图形以消耗更少的功率。 对于由驾驶员选择以接收指导的那些部分,导航系统实现高细节操作模式,其中导航系统能够将音频视觉上传达到用于到达给定目的地的驾驶员指令。 以这种方式,将更有效地利用导航系统消耗的功率。
