Fig. 2 illustrates the guide vehicle from " the unknown " position to the illustrated examples of the course of expecting.
In this illustrative embodiment, vehicle 203 is arranged in the parking lot 201 of buildings 211 back.This parking lot is not included in the systematically diagram data of the computing system (or personal navigation apparatus 54 or vehicle navigation apparatus 60) based on vehicle, neither download to the parking lot data of system.
The advance route of 209 marks of vehicle driver expectation finally turns right to the second street 215.Obviously, 209 straight line path is a difficult problem from vehicle 203 to route in map expression in system, and this is that vehicle probably knocks many buildingss or roadside, Intermediate Gray etc. because in this case.
On the contrary, system will provide (for example) simple spoken command (such as " travelling to the Ford road ").If system does not have navigation indicator, and can not show intuitively the expression of desired road/route to the user, then this spoken command can be particularly useful.
System also can provide the other direction such as " travel and enter the Ford road " northwards, in order to advance to more easily recommended initial road 207.Use these directions and airborne compass, the driver can command vehicle 203 to leave the parking lot through exporting 205, even do not know to export 205 existence based on computing system and the navigation arrangement of vehicle.
When vehicle had left the parking lot and enters recommended road, system can command vehicle 219 to arrive main street 209 along the path subsequently, route 217 occurs at some place of main street 209, advances to the first street 213, and finally arrives the second street 215.
Fig. 2 A illustrates the example process be used to the direction of the course that expectation is provided from the position of " not representing at map ".
In this illustrative embodiment, at first determine the gps coordinate (251) of vehicle based on the computing system of vehicle.For example, can be by finishing to call (perhaps GPS being connected to processor by wired connection or wireless connections) that be included in the GPS in the vehicle from being included in based on the processor the computing system of vehicle.
When processor obtained gps coordinate, at least in this embodiment, processor also can (for example) use airborne compass to determine vehicle course (253).(if definite) can be sent to telecommunication network (255) for gps coordinate and course.In this illustrative embodiment, processor is connected to such as cellular mobile device, but is not limited to this.Processor sends to cell phone or other mobile devices with data, and mobile device is connected to telecommunication network, to finish transmission.
Processor receives response (257) from telecommunication network subsequently.In addition, in this illustrative embodiment, response sends to mobile device from network, re-sends to processor.
According to this illustrative embodiment, if vehicle (for example, in the parking lot, but is not limited to this) at present not on known road, then described response will comprise at least one recommended road that vehicle should advance to.
Vehicle can advance to different kinds of roads from the parking lot.A road is selected in the course (course in the time of transmission or present course) of telecommunication network (or processor) can at least part of gps coordinate based on vehicle (coordinate in the time of transmission or present coordinate) and/or vehicle.
Because having " delays " between the reception of the transmission in coordinate and/or course and response spends, therefore the developer can select to make network to carry out as expect near the calculating of the road of arrival, perhaps, in order to avoid better this delay, the developer can select to make the processor reception for some options of road, and carries out calculating based on real-time location and course data subsequently.
When receiving response and having selected recommended road, the road that processor can indicate the driver of vehicle to enter subsequently is to arrive the course (258) of expectation.For example, can indicate by vehicle audio frequency system or at the display of navigation.
Based on the computing system of vehicle can be subsequently the at once periodically relatively GPS of vehicle location and the coordinate (259) corresponding with recommended road and any other possible known road relatively or in some predetermined amount of time.
Can finish in every way this process, the shown here example is only for the purpose of illustrating.System also will check current coordinate whether corresponding with recommended route (263), if not, then check subsequently they whether with " known " route (for example, substitute road, but be not limited to this) correspondence.If neither on recommended route, also not on known route, then system can continue to get back to step 251 to coordinate, perhaps, selectively, for example, continue to get back to step 259 (not shown) to continue to check coordinate in the section at a fixed time, until arrive known route etc.
If the current coordinate of vehicle is corresponding with known route, and not corresponding with recommended route, then system will seek the route (265) of advancing based on the current location of vehicle.For example can be by the map datum of the local storage of use or by carrying out this definite step with communicate by letter (for example, if local map datum is inadequate) of telecommunication network.
When route is known, vehicle will provide next prescription to (267) to the user.
Fig. 3 illustrates the illustrated examples that little wiring system realizes.
In at least one illustrative embodiment, the data relevant with the current position of vehicle are sent to telecommunication network from the computing system based on vehicle.But, in this embodiment, do not exist with the direct of network based on the computing system of vehicle to be connected.On the contrary, information exchange is crossed with being connected of mobile device and is sent, and mobile device provides and the communicating by letter of network.In addition, can finish this transmission in the mode of data-over-voice, so that bandwidth can be limited.
Although this method also provides high-speed traffic, before being sent to network and getting back to vehicle, information needed has some seconds delay.Because it is not vehicle is at that time may be in motion, therefore may be not corresponding with the position of vehicle when responding the received time about the information of the position of the vehicle when request is sent to network.
For example, if vehicle just with per hour 60 miles movements on roads, and has 4 seconds delay, then arrive subsequently till the received time of response, vehicle will be to advance 352 feet along the about multirow of road.If the outlet that vehicle will turn to when request is sent out then can go wrong only along 250 feet in road.Vehicle also may turn to bypass (not being to advance at bypass before the vehicle) etc.
In the example shown in Figure 3, vehicle is answered course 303, to arrive predetermined destination.That is to say, under optimal conditions, vehicle will (position 301 in the drawings) continue to keep straight on from its present position, and 309 places turn in the position.
But, if buildings is arranged, if perhaps vehicle turns to just (because the driver has made unexpected turning to), then need now to change the instruction for vehicle.
In the example that illustrates, the vehicle driver will receive instruction at first, to travel eastwards in the A street and to turn left in the second main road.Certain point before the vehicle point of arrival 301 places receives these instructions.
At point 301 places, the instruction that the vehicle request is upgraded (for example, as the part of general communication, to guarantee the integrality of route).Vehicle is just advanced with (for example) a hour 30 miles at present.Be sent to network and till the received time of response, vehicle has departed from projected route, and now at position 301a place to instruction request.
If remote system only sends it back for the data of optimal route and instruction (that is, from the A street to the second main road), then need further to ask to send to system based on new vehicle location.Certainly, when request was being processed, vehicle can change the position again, and a succession of direction that causes arriving may be too late and useless.
But in this illustrative embodiment, vehicle course and speed send together with gps coordinate.Use this information, network can be estimated the possible position that the vehicle when information is returned time based on the computing system of vehicle can be positioned at.
In this illustrated examples, system may be positioned at 313,311,309 or 307 places based on present speed and course estimation vehicle.Therefore, the direction of the course from those to first-selection (or at least map datum) is provided for the computing system based on vehicle.
By this way, system can be provided to the direction of first-selected course exactly, and no matter in the most close 4 points of vehicle which.
Therefore, for the example that illustrates, vehicle has been moved to position 301a.Because the most close position 311, this position (and vehicle towards the position 311), therefore based on the computing system of vehicle will to driver provider to, to advance along route 305, until route 305 converges first-selected course 303.System also can come based on different possible position points again to the destination programme path.
In addition, in this illustrative embodiment, the possible position point is positioned at the about 180 degree circular arcs of vehicle front.Prevent from like this being sent to without meaning computing system based on vehicle about the data at all potential routes of each direction.If the developer wishes to suppose that vehicle will seldom change and the accidents that surpass 180 degree turn to, then above-mentioned is effective.Certainly, also can send the data of the wider or narrower rational frequency spectrum that is suitable for possible position.
Fig. 4 illustrates be used to using little wiring system that the illustrated examples of the process of route is provided.
In this illustrative embodiment, determine coordinate, speed and the course (401) of vehicle based on the processor of the computing system of vehicle.Speed and course information can be usually obtain from the CAN bus of vehicle, and are usually provided by existing Vehicular system.
Gps coordinate can obtain from (for example) built-in GPS.Gps coordinate also can be from being connected to the GPS acquisition based on the computing system of vehicle by wired connection or wireless connections.In another illustrative embodiment, gps coordinate can be offered computing system based on vehicle such as cellular mobile device.
When processor obtained coordinate, speed and/or course, system sent to telecommunication network with in these information some or all.
In this exemplary embodiment, by with mobile device be connected to finish telecommunication network transmission.Computing system based on vehicle sends to described mobile device with information, and this mobile device sends to telecommunication network (403) with information.
System waits the response (405) from telecommunication network subsequently.
When telecommunication network is finished the processing of solicited message, based on the computing system reception response (407) of vehicle.This response comprises one or more expectation vehicle location points.These estimate that vehicle location points are and star-like corresponding point in Fig. 3.
Described estimating position point compares (409) with the actual GPS location of the vehicle of (perhaps when finishing comparison etc.) when response is received subsequently.Unless the prediction of network is very inaccurate, unless perhaps (at least in this example) Vehicular turn surpasses 180 degree, vehicle should the most closely be arranged at least one of estimating position point.
When which point is system know when nearest from vehicle, subsequently from that provider to.Probably, local map datum can comprise these information, therefore if vehicle is not directly at the predicted point place, then to the direction of this point also can in the situation that needs be provided.
If vehicle is kept off one in the predicted point, then system can use identical information to another prescription of calling network to.This embodiment is illustrated by the dotted line option in Fig. 4.System at first checks to note present gps coordinate whether in the tolerance distance of nearest predicted point, and replaces directly continuing to provide the direction (413) from nearest predicted point.If not so, system repeats the calling to server, otherwise direction is as being provided in the first illustrative embodiment.
Although described various exemplary embodiments, illustrative embodiment and unrestricted embodiment in detail, the technician who is familiar with the field that this invention relates to will recognize for implementing only various alternate design of the present invention defined by the claims and embodiment.
