Abstract
A vehicle comprises memory for storing map data and a global positioning system (GPS) module that transmits vector and location data and that receives traffic reports from a remote traffic monitoring system. An adaptive map building module includes a path determining module that determines a travel path of the vehicle based on the vector and location data, a comparing module that compares the travel path to roads defined by the map data, and an identifying module that selectively identifies new roads based on the comparison.
Claims51
A vehicle comprising:
- memory for storing map data;
- a global positioning system (GPS) module that transmits vector and location data and that receives traffic reports from a remote traffic monitoring system;
- and
- an adaptive map building module including:
- a path determining module that determines a travel path of said vehicle based on said vector and location data;
- a comparing module that compares said travel path to roads defined by said map data;
- and
- an identifying module that selectively identifies new roads based on said comparison.
A cellular phone comprising:
- memory for storing map data;
- a global positioning system (GPS) module that transmits vector and location data and that receives traffic reports from a remote traffic monitoring system;
- and
- an adaptive map building module including:
- a path determining module that determines a travel path of said cellular phone and based on said vector and location data;
- a comparing module that compares said travel path to roads defined by said map data;
- and
- an identifying module that selectively identifies new roads based on said comparison.
A vehicle comprising:
- storing means for storing map data;
- global positioning system (GPS) means for transmitting vector and location data and for receiving traffic reports from a remote traffic monitoring system;
- and
- adaptive map building means for updating said map data including:
- path determining means for determining a travel path of said vehicle based on said vector and location data;
- comparing means for comparing said travel path to roads defined by said map data;
- and
- identifying means for selectively identifying new roads based on said comparison.
