Route Determination and Driver Warning System
First Claim
Patent Images
1. A method for determining a route from a start point to a destination for a vehicle, the method comprising:
- (a) providing road segment passage restriction information for a plurality of road segments;
(b) providing vehicle passage restriction data characterizing the vehicle; and
(c) determining a route from the start point to the destination for the vehicle based upon both the vehicle passage restriction data and the road segment passage restriction information.

Abstract
A system for determining a route and for warning a driver of a vehicle and corresponding methods are provided. The systems include storage units that store road segment passage restriction data and vehicle passage restriction data. The systems further include a working memory unit and a processing unit that determine a route to be displayed on an output unit or that provide a warning signal output, depending upon both the vehicle passage restriction data and the road segment passage restriction data.

8. A method of warning a driver of a vehicle, the method comprising:
-
(a) providing road segment passage restriction information for a road segment;
(b) providing vehicle passage restriction data characterizing the vehicle;
(c) comparing the vehicle passage restriction data with the passage restriction information of the road segment; and
(d) outputting a warning signal, depending upon the result of the comparing. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A system of route determination for a vehicle, comprising:
-
(a) a first storage unit containing road segment passage restriction information;
(b) a second storage unit containing vehicle passage restriction data characterizing the vehicle;
(c) a working memory unit for storing a subset of the road segment passage restriction information and the vehicle passage restriction data; and
(d) a processing unit coupled to the working memory unit and adapted to determine a route from a start point to a destination based upon both the road segment passage restriction information and the vehicle passage restriction data. - View Dependent Claims (20, 21, 22, 23, 24)

25. A system for warning a driver of a vehicle of a potential problem along a route, the system comprising:
-
(a) a first storage unit containing road segment passage restriction information;
(b) a second storage unit containing vehicle passage restriction data characterizing the vehicle;
(c) a working memory unit for storing road segment passage restriction information of at least one road segment and the vehicle passage restriction data;
(d) a processing unit coupled to the working memory unit and adapted to compare passage restriction information of the road segment with the vehicle passage restriction data; and
(e) an output unit coupled to the processing unit to receive a control signal therefrom and adapted to output a warning signal based upon the control signal. - View Dependent Claims (26, 27, 28, 30)

31. The system of route determination for a vehicle, comprising:
-
(a) a first storage unit that stores a first and a second passage threshold value for a road segment;
(b) a second storage unit that stores a vehicle parameter; and
(c) a processing unit that compares the vehicle parameter to both the first and the second passage threshold value for the road segment and determines a route based upon a result of the comparison.
