Vehicle route planning system
First Claim
1. A vehicle route planning system comprising:
- map memory means for storing fixed road path data corresponding to fixed roadways available for vehicle travel;
detour means for having a system user designate, via stored detour data, which of said road path data should be excluded in calculating a desired route between vehicle start and destination locations;
route planning means coupled to said map memory means and detour means for utilizing said fixed road path data, exclusive of the road path data corresponding to said detour data, to calculate route data defining a desired route, via said fixed roadways, for vehicle travel between said vehicle start and destination locations, andmeans for providing route information to said system user based on said calculated desired route data,wherein the improvement comprises said detour means comprising system detour means for having said system user designate some of said detour data as system detours and wherein said route planning means excludes road path data defined by said system detour data from use by said route planning means for calculating all of said desired routes calculated by said route planning means, said detour means also including subsystem detour means for having said system user designate some of said detour data as subsystem detours and wherein said route planning means excludes road path data defined by said subsystem detour data from use by said route planning means for calculating some, but fewer than all, of said desired routes which may be calculated by said route planning means.

Abstract
Vehicle route planning system (10) uses a route planning apparatus (13, 19) to calculate a desired route between start and destination locations. Apparatus (16, 17) provides route information based on the calculated route. The route is calculated in accordance with fixed road path data stored in a memory (14). A user of the system (10) uses input devices (11, 12) to specify "detour" data that define what stored road path data should not be considered in calculating the desired route. A navigation computer (13) allows the system user to designate the detour data as "system detour data" to be used for excluding road path data for all routes calculated for all drivers to all destinations or to designate the user specified detour data as "subsystem detour data" which is used for excluding road path data for calculating some, but fewer than all, routes to be calculated. Preferably, the subsystem detour data includes driver ID associated detour (route calculation) data and/or trip associated detour data. The user designation and entry of different types of detour data allows the system ( 10) to achieve system flexibility while minimizing the time and effort involved by the user in entering detour data which may be used in calculating several trips.
