Abstract

A method for providing waypoint data to a vehicle controller. This method may include obtaining a plurality of coordinate locations describing a vehicle route, performing a computation of the vehicle route using said coordinates, obtaining route data describing the route, transforming the route data into coordinate data comprising a plurality of data points expressed in longitude and latitude form, converting the coordinate data into properly-spaced waypoint data, storing the waypoint data in a form accessible to a vehicle controller, and accessing the waypoint data via a vehicle controller. According to an exemplary embodiment, the properly-spaced waypoint data may be created from improperly-spaced data via interpolation. The vehicle controller may control other devices associated with a vehicle, such as an automated voice announcement system or an external display.

converting, with the processor, the coordinate data into properly-spaced waypoint data by ensuring that no sequential pairs of coordinate data are more than a predetermined distance from one another, wherein each pair of coordinate data points of the coordinate data represent a waypoint along the vehicle route;

designating, with the processor, a plurality of the waypoints in the waypoint data as scheduled stops of a vehicle route;

storing, with the processor, in the memory module, the waypoint data in a form accessible to the vehicle controller;

accessing the waypoint data via the vehicle controller, the vehicle controller further comprising a vehicle controller processor and a vehicle controller memory and configured to automatically control the operation of at least one component of the vehicle;

controlling the operation of at least one component of the vehicle based on the waypoint data accessed by the vehicle controller while the vehicle is traversing the vehicle route, and based on a measurement of an odometry system of the vehicle;

wherein the at least one component of the vehicle comprises an automated voice announcement system and an external display, and wherein the vehicle controller is configured to access instructions associated with the waypoint data and automatically trigger an announcement from the automated voice announcement system and automatically trigger information to be displayed on the external display based on the instructions.

2. The method of claim 1, wherein the coordinate data is converted into properly-spaced waypoint data by linear interpolation.

3. The method of claim 1, wherein the coordinate data is converted into properly-spaced waypoint data by nonlinear interpolation.

4. The method of claim 1, further comprising using the automated voice announcement system to play an announcement to passengers of the vehicle when a selected waypoint has been reached.

5. The method of claim 4, wherein the selected waypoint comprises a stop, and further comprising making a stop announcement as the vehicle approaches the stop.

6. The method of claim 1, wherein the waypoint data comprises a waypoint comprising a next planned stop, and further comprises instructions directing the external display to display the name of the next planned stop, said instructions being associated with a particular waypoint preceding the waypoint comprising the next planned stop;

and wherein the vehicle controller is configured to automatically display, on the external display, the next planned stop of the vehicle based on the instructions when the particular waypoint has been reached.

7. The method of claim 1, wherein the waypoint data further comprises distance measurements.

8. The method of claim 1, wherein the waypoint data further comprises instructions for the at least one component of the vehicle controlled by the vehicle controller.

9. A method for providing waypoint data to a vehicle controller, this method comprising:

accessing, with a processor, an external mapping application programming interface (API);

selecting, with the processor, a plurality of locations describing a vehicle route;

obtaining, with the processor, from a memory module, a plurality of coordinates corresponding to the plurality of locations;

generating the vehicle route that incorporates said coordinates by utilizing the external mapping API;
