Abstract:
1. A method for conserving power in a GPS-based navigation system, the method comprising: receiving a destination from a driver of a vehicle; identifying a current location of said vehicle; determining a route to travel from said current location of said vehicle to said destination; presenting to said driver a map of an overview of said route on a display; receiving input from said driver selecting on said displayed map a first portion of said route requiring said GPS-based navigation system to enter a high detail mode of operation; implementing, by a processor, a low detail mode of operation on a second portion of said route in response to said driver not selecting said second portion of said route to require said GPS-based navigation system to enter said high detail mode of operation, wherein said low detail mode of operation consumes less power than said high detail mode of operation, wherein said low detail mode of operation comprises a reduction in update frequency for presenting information by said GPS-based navigation system in comparison to said high detail mode of operation, wherein said low detail mode of operation comprises dimming a screen and displaying less detailed graphics than displayed in comparison to said high detail mode of operation; generating a notification while said vehicle is in said second portion of said route indicating said vehicle is approaching said first portion of said route, wherein said notification is not an update for presenting information; preemptively updating more frequently the driver with navigation instructions while still in said low detail mode of operation by said GPS-based navigation system prior to said vehicle reaching said first portion of said route; and implementing said high detail mode of operation upon entering said first portion of said route.
