Abstract
Description
- This invention relates generally to the navigation of a moving vehicle. In particular, this invention relates to a method and system for decreasing the number of shape points to increase effectiveness and response time of a server-based navigation system.
- Onboard vehicle navigation technology has come a long way in the recent years. Existing computer capabilities coupled with wireless and Global Positioning Satellite technology is making huge advances in taking some of the high cost out of “real time” vehicle navigation. There are different systems to make this technology work (for example, onboard autonomous systems vs. server-based navigation systems). There are also a number of different methods to support this technology. On server-based navigation systems, the client is placed onboard the vehicle while the server, communicated with through wireless and often satellite technology, plays host to most of the source applications and databases.
- Within onboard vehicle navigation systems, there is a predetermined list of location points where a vehicle is instructed to proceed in a certain direction (i.e., turn right, turn left, etc.) This list is known as a maneuver list and the points on this list are known as maneuver points. The maneuver list is processed from a server based database to a client processor onboard the vehicle. Within each maneuver point are geodesic points (hereafter known as shape points). Each shape point has a latitudinal and longitudinal value identifying its location with respect to its physical location on the surface of the earth. The number of shape points and the position of shape points, determines the geographic condition of the path being navigated (e.g., curvy line vs. straight line).
- The processing of this information is necessary to determine vehicle location and to generate correct navigation instructions. The server based processing for this is time consuming and this processing time is dependent on the amount of data input into the server. Navigation instructions must be generated and transmitted to the vehicle in a timely fashion to provide a useful navigation system. For example, if a vehicle has passed a maneuver point on a route it will need instructions on the next maneuver at an acceptable time before it reaches or exceeds that next maneuver point. Receiving maneuver information after passing the maneuver point is useless and compromises the need for the navigation system.
- The number of shape points to be processed has a direct correlation to the amount of processing time and the amount of physical processor based memory needed for the navigation system to operate effectively and generate timely and accurate instructions. Navigating on extremely curvy routes, which require numerous shape points, could potentially warrant the design and installation of onboard vehicle navigation systems that are cost prohibitive.
- It would be desirable, therefore, to provide a method to reduce shape points to provide more effective and timely navigation instructions to a moving vehicle that overcomes the above.
- One aspect of the present invention provides a method for generating navigation instructions for a vehicle. A number of shape points between a set of primary maneuver points may be determined. A determination may be made as to whether the number of shape points exceeds a cardinal threshold. A bearing between a first shape point and a second shape point may be determined if the number of shape points exceeds the cardinal threshold. It may be determined whether the bearing exceeds an angular threshold. The second shape point may be eliminated if associated bearings exceed the angular threshold. In one embodiment, the angular threshold may be predetermined. In still another embodiment, the cardinal threshold may be predetermined.
- Another aspect of the present invention provides a system for generating navigation instructions for a vehicle. The system may include means for determining a number of shape points between a set of primary maneuver points, means for determining whether the number of shape points exceeds a cardinal threshold and means for determining a bearing between a first shape point and a second shape point, if it is determined that the number of shape points exceeds the cardinal threshold. It may also include means for determining whether the bearing exceeds an angular threshold and means for eliminating the second shape point if it is determined that associated bearings exceed the angular threshold.
- Another aspect of the system provides a computer usable medium including a program for generating navigation instructions for a vehicle. The program may include computer readable program code that determines a number of shape points between a set of primary maneuver points and computer readable program code that determines whether the number of shape points exceeds a cardinal threshold. It may also include computer readable program code that determines a great circle distance and a bearing between a first shape point and a second shape point, if it is determined that the number of shape points exceeds the cardinal threshold. The program may also include computer readable program code that determines whether the bearing exceeds an angular threshold and computer readable program code that eliminates the second shape point if it is determined that the bearing exceeds the angular threshold.
- The foregoing and other features and advantages of the invention will become further apparent from the following detailed description of the presently preferred embodiments, read in conjunction with the accompanying drawings. The detailed description and drawings are merely illustrative of the invention rather than limiting, the scope of the invention being defined by the appended claims and equivalents thereof.

- In operation, communication is established with the
Navigation subsystem 150 by a call from thenavigation client 110. This call may be a request for navigation information or may include transmission of the coordinates of the vehicle. Communication between thenavigation subsystem 150 and thevehicle client 110 is continuous throughout the navigation of the vehicle. The vehicle client sends constant updates of vehicle location information to thenavigation subsystem 150. Theroute generation application vehicle client 110. The maneuver list includes maneuver points, and shape points that identify the longitudinal and latitudinal values of a point on a route and the geography of the space in between two consecutive points (i.e., curvy vs. straight, etc) on a route. - The route generation application housed on the
navigation subsystem 150 analyzes the maneuver list (block 305). This may done by identifying a first maneuver point on the maneuver list and a second maneuver point on the maneuver list. The route generation application may then count the number of shape points between the first maneuver point and a second maneuver point on a route (block 306). - On the
route navigation subsystem 150 server, a cardinal threshold and an angular threshold are determined (not shown) byroute generation application - A determination may then be made on whether the number of shape points that exist between the first maneuver point and the second maneuver point on a route, exceeds the cardinal threshold number (block310). If it does not exceed the cardinal threshold, then the vehicle client may be considered to be navigating on a path between the first maneuver point and the second maneuver point that has limited geographic variance, and the next consecutive maneuver point on the maneuver list may be analyzed (block 345).
- If the number of shape points to be navigated by a vehicle with
onboard client 110 between two consecutive maneuver points does exceed the cardinal threshold, the first two consecutive shape points may be selected for analysis (block 315). - In one embodiment, a great circle distance may be calculated by a method that is known in the art between the first shape point and the second consecutive shape point selected for analysis (block320).
- The angular bearing may be calculated by a method that is known in the art between the first shape point and the second consecutive shape point selected for analysis (block325). In one embodiment, the great circle distance may be used in determining the angular bearing.
- A determination may be made as to whether the calculated angular bearing between a first maneuver point and a second shape point on a maneuver list exceeds a predetermined angular threshold value (block330). If the angular bearing does not exceed the angular threshold then it is determined if the current maneuver point is the final maneuver point on the maneuver list (block 336). If it is determined that the current maneuver point is the final maneuver point, then the server may transmit the maneuver list to the vehicle client (block 338). If it is determined that it is not the final maneuver point, then the next maneuver point on the maneuver list may be analyzed (block 345). If the bearing angle does exceed the angular threshold, then the second shape point may be eliminated (block 335). The elimination of shape points may be performed under a technique known as “smoothing” that allows for the elimination of a data point if values adjacent to the data points are known. Estimates may be determined by using these adjacent values and graphically interpolating the value of a third data point.
- Once the second shape point has been eliminated the next consecutive shape point between the first and second maneuver point may be selected for analysis (block340). Steps shown in
block 320 throughblock 340 may be repeated until all of the shape points between the first and a second maneuver point have been selected and analyzed. - FIG. 4 is a sequence diagram, illustrating an example of one embodiment of a method for reducing shape points for generating navigation information for a vehicle in accordance with the present invention at400.

Points route 450.Maneuver point 411 may be the starting location of thevehicle client 410. Maneuver points 420, 425, and 430 may be intermediate locations of thevehicle client 410 onroute 450 and,maneuver point 440 may be the final location of thevehicle client 410 onroute 450. - As
vehicle client 410 travels frommaneuver point 411 to maneuverpoint 420 thevehicle client 410 accesses the maneuver list and crosses oneshape point 416. For the purpose of illustration, the cardinal threshold in this example is 2. Because the number of shape points betweenmaneuver point 411 andmaneuver point 420 does not exceed the cardinal threshold, the next pair of consecutive maneuver points (420,425) is analyzed. There are four shape points (421, 422, 423 and 424) betweenmaneuver point 420 andmaneuver point 425. Because this exceeds the cardinal threshold, the first two consecutive shape points (421, 422) are selected for analysis. The great circle distance and angular bearing for the selected shape points may be calculated by a technique known in the art. For illustration in this example, the angular bearing is assumed to exceed the angular threshold and therefore thesecond shape point 422 may be eliminated. When the navigation information is transmitted to the application server, the geographic profile of the path frommaneuver point 420 to maneuverpoint 425 may be calculated without consideration ofshape point 422. Thenext shape point 423 may be selected for analysis. For illustration in this example, the angular threshold is not exceeded and therefore shapepoint 423 will be retained. When the navigation information is transmitted to the application server, the geographic profile of the path frommaneuver point 420 to maneuverpoint 425 may be calculated with consideration ofshape point 423. Thenext shape point 424 may be selected for analysis. For illustration in this example, the angular threshold is not exceeded and therefore shapepoint 424 will be retained. When the navigation information is transmitted to the application server, the geographic profile of the path frommaneuver point 420 to maneuverpoint 425 may be calculated with consideration ofshape point 424. The next pair of consecutive maneuver points (425, 430) may be analyzed. There is only one shape point (426) betweenmaneuver point 425 andmaneuver point 430. Because this does not exceed the cardinal threshold, the next pair of consecutive maneuver points (430 and ending maneuver point 440) can be analyzed. Shape points 431 and 432 are the only two shape points betweenmaneuver point 430 and endingmaneuver point 440, therefore the cardinal threshold has not been exceeded and both shape points (431, 432) may be retained. When the navigation information is transmitted to the application server, the geographic profile of the path frommaneuver point 430 to maneuverpoint 440 may be calculated with consideration ofshape point 431 andshape point 432. - While the embodiments of the invention disclosed herein are presently considered to be preferred, various changes and modifications can be made without departing from the spirit and scope of the invention. The scope of the invention is indicated in the appended claims, and all changes that come within the meaning and range of equivalents are intended to be embraced therein.
