  • Patent number: 8332140
    Abstract: A method and apparatus to optimize energy consumption in a mobile phone having a navigation system is disclosed. The navigation-based method and apparatus efficiently use a smartphone battery to provide the highest possible location accuracy to the driver. When the driver is travelling from a complex route segment to a less complex route segment, current location sensor is switched to another location sensor with lower location accuracy which consumes less battery power. When the driver is travelling from a less complex route segment to a complex route segment, the navigation system continues to use a location sensor with lower accuracy until the navigation system determines that switching to higher accuracy location sensor is necessary to conserve more battery power. The navigation system can determine a best timing to switch according to the driver's familiarity with the route segment or geographical area.

  • Patent number: 8306741
    Abstract: A navigation method and apparatus uses routing data created by a remote navigation server for a route guidance operation by an individual navigation system. The navigation method and apparatus makes use of the most currently updated map data and the high calculation power of the remote navigation server for creating the calculated route and utilizes the calculated route for the route guidance operation by the individual navigation system. The navigation method and apparatus decreases an amount of routing data indicating the calculated route by employing a concept of strategic road segments for sending the routing data to the individual navigation system. The individual navigation system recreates the calculated route based on the routing data received from the navigation server for the route guidance operation to the destination.
