Wherein, the running data in the present embodiment at least includes link speed information data and crossing stand-by period number According to.

In the case where needing to calculate remaining time, in the case of generally there is programme path, described in this method The running time that vehicle is arrived at, is vehicle is arrived in programme path position.

The running time for corresponding road section running time it is the crossing stand-by period with corresponding crossing and.

Preferably, the link speed information data include first via segment information, temporal information, mean velocity information and go through History velocity information, the link speed information data are associated with navigation map data；

The first paragraph road section information includes that section identifies and/or sub- section mark, and the sub- section is to different sections of highway According to the pavement branch sections that default partition value is divided；The section that the road section information determines represents when being produced with the historical speed information Positional information it is corresponding；

The temporal information is the time corresponding preset period of time represented when the historical speed information is produced；

The dwell time is that the speed of vehicle is less than the time represented during predetermined threshold value；

The entry time sails the time in section into for vehicle drives into；

The temporal information is the preset period of time corresponding to the dwell time；

Crossing stand-by period average is the average value of the history crossing stand-by period of different periods.

Existing navigation equipment all provides route remaining time computing function, but most of is all divided by speed using distance Mode, this mode is inaccurate, and error is larger.So the present invention provides a kind of brand-new route based on user's running data and remains Remaining Time Calculation mode.

The idiographic flow of this method is：In the case where there is programme path, the row of user is obtained from navigating memory Data are sailed, the running data from all sections from truck position to destination route is read, there is non-intersection speed of the present invention to remember Record table understands, the index relative of the running data associated therewith of road in map datum is had built up, so on reading route The running data of all roads is also very convenient, without considering performance issue.Each small portion in the section recorded in detail in data The speed information for dividing, and, each road section length will also realize that by form, so using every distance in sub- section divided by respective The history speed of current slot, so that it may obtain the time consumed on every sub- section.

For example, after route planning is completed, each sub- section is read on the pathway of storage in all sections in the same time Speed average in the historical record of section, because the data being locally stored are the situation of the multiple traveling of user, such as certain section of road, User repeatedly after herein, by the speed average value 40KM/h in travel data, uses the speed average value being locally stored 40KM/h, the length according to each section was tried to achieve in used by each section time, was added up by the stand-by period of intersection, The stand-by period of intersection, the average value was by repeatedly mutually passing through the road in the same time using the signal lamp average value for locally recording The stand-by period of mouth calculates, and can run into stand-by period situation more long at multipass crossing, it is also possible to which existing is The situation of green light, the stand-by period is 0, and the stand-by period is averaged by multiple history Data-Statistics, this meter When calculation method passes through crossing without consideration, the state of signal, completely by prolonged empirical value.When being used by section Between and the time used by signal lamp can try to achieve remaining time of whole route, this statistical not only considers the every of each section The speed of a bit of road is different, and user is in the historical data number of the time period, and has considered the consistent behavior of user i.e. In the frequent habitually speed of operation in a certain section, also by the stand-by period of signal lamp, more can accurately try to achieve surplus The remaining time.During user travels, often by one section and after distance, remaining time can be certainly for remaining time dynamic calculation, i.e. user It is dynamic to calculate again once according to the method described above again.

Further, when with network-in-dialing, the information of guider can also be interacted with server, also including repairing The step of corresponding speed in positive residue section, such as Figure 13, described amendment step is specifically included：

S211:Obtain the real-time speed of server transport；

S212:Judge the real-time speed with the average speed value in corresponding running data whether more than the abnormal threshold of setting Value；Described outlier threshold can freely set according to the actual requirements.

S213:If being more than outlier threshold, calculated by the time of corresponding road section by real-time speed；

S214:If no more than outlier threshold, by the flat of the average speed value that is stored in real-time speed and running data The time that mean value computation passes through corresponding road section；

S215:Remaining time is recalculated according to different velocity amplitudes.

Specifically flow is：When navigation equipment possesses the communication function of network, at this moment on route remaining time calculating Method equally provides above-mentioned method, when driving, with the movement of vehicle, remaining time constantly updating, while Also can constantly recalculate, and can be to all without the real-time of section on server request route in calculating again Vehicle speed value, after obtaining the real-time speed of server, in addition it is also necessary to reference to the historical data in local running data, to being applied to road Speed in the calculating of line remaining time does an amendment, for example, the real-time speed obtained from server is 50KM/h, and it is local History road speed 40KM/h, then calculating the speed for using should use revised 45KM/h, and amendment here is mainly examined Consider the otherness of active user, the speed on server is a representative for most of user velocities, it is impossible to represented completely Active user, it is considered to which user's history data are the reference of user behavior, differentiation of such calculating closer to time user.

Another situation is：The situation for not passing through section accident is identified by service end, is such as obtained from server The real-time speed in a certain section be 5KM/h, and local history road speed 40KM/h, the appearance of this feelings just imply that this section Road gets congestion, and the local running data of user is to store the vehicle speed condition in one period of user, is to predict The jam situation that this accident is caused, then calculating the speed for using should use revised 5KM/h, if certain one Congestion changes after the section time, then the real-time vehicle speed value obtained from server end can also be reflected, while remaining time Also by being calculated amendment, can realize that the comparing of the remaining time under the influence of accident is smart by this calculation It is really rational to calculate.

Further, the calculations incorporated current time of the remaining time of this method reaches each with running data prediction vehicle Remaining section and/or the predicted time section at remaining crossing, different sections of highway is in corresponding predicted time section in obtaining running data Speed average and/or mean value calculation remaining time crossing stand-by period.

Such as Figure 14, specific step includes：

S221:Obtain current location to the corresponding all sections of destination locations；

S222:The predicted time section for reaching each section and crossing is calculated according to running data；

S222:Predicted time section according to each section and crossing is reached obtains corresponding section and crossing in running data Predetermined speed and prediction the crossing stand-by period；

S224:The corresponding time by section and remaining crossing are calculated by predetermined speed and prediction crossing stand-by period The crossing stand-by period, so as to calculate remaining time.

Due to being stored on a time period to speed in running data, so can be using working as from section where car Preceding navigation system time, indicates the sign that meter calculates current time, further according to time-tagging from corresponding road according to the time period In section speedometer, speed average is taken out, the pre- of the arrival section can be used for the time used by other section acquisition speeds The survey time.

The computational methods of predicted time are when being consumed by each section from before bus or train route section current time+the reach section Between, and the stand-by period for passing through the signal lamp at each crossing.The time segment identification used by the stand-by period of signal lamp is obtained, can Obtained by time period sign table again with by first calculating the time predicted up to the crossing.

By that analogy, the remaining time to destination locations be：Each section consumption time+by crossing wait when Between.When driving, with the traveling of vehicle, the remaining time on section needs to recalculate, because user is in the short time The change of interior road speed, the signal lamp stand-by period passed through and original prediction gap are larger etc., to reaching next section of road Time all has a significant impact, so constantly can in real time calculate remaining time in driving.

This method considers user by the historical data after long run, it is also considered that possible by signal lamp Stand-by period, the road conditions in one a period of time in region of most of time be it is more stable, and each user driving practise Used is also for a long time to fix very much once being formed, that is, the speed driven on fixed road is also that a habituation is moved Make, then after with reference to the long-term historical data of user, the remaining time of calculating more presses close to the actual conditions of each user, more Plus accurate, hommization.

Embodiment three

In the embodiment of the present invention three, there is provided speed change reminding method and device based on running data, described speed change Prompt message is to calculate what is obtained based on the running data stored in embodiment one.

The invention provides a kind of speed change reminding method based on running data, such as Figure 18, the running data includes car The incidence relation in section in fast changing value and map datum, its specific step is：

S301：Generate and store running data；

S302：Obtain the speed change information in running data；

S303：Correspondence position by speed change information in section makes speed change alarming sign；

S304：Output in position travels warning information.

The appropriate location is that vehicle is travelled to the locality including speed change alarming sign, apart from the spacing of position one From when, output traveling warning information, it is described it is certain can be specifically adjusted according to speed, such as when speed is very fast, can Pointed out with the slightly remote position of distance, if speed is slow, car can be pointed out in the slightly near position of distance, specifically Parameter can be set according to user's request.

Preferably, the remaining time of current location to the position with speed change alarming sign is calculated, by setting fixation Time judges the output opportunity of traveling warning message, it is ensured that brings user and accurately points out, and lifts the security for driving.

The speed change alarming sign is the section mark made according to speed change information in running data, and it can be sound Sound is pointed out, or the warning mark in electronic map now, or the two has concurrently etc..

Preferably, reference implementation example one, the method for generating the running data includes：When matching speed changing value is produced Section in position relationship and map datum, judges to be cut in generation section switching speed change information or section according to matching result Change trains fast change information.

Preferably, the section switching speed change information includes rolling section mark away from, sails section mark, time letter into The unchanged number of times record of breath, continuous speed change frequency record, continuous speed, velocity variations average value and velocity variations value Associated storage, it is described roll away from section from it is described sail into section for it is different and continuously section.

Preferably, speed change information is switched in the section includes section mark, sub- section mark, the change of continuous speed The associated storage of the unchanged number of times record of number of times record, continuous speed, speed change mean and history speed changing value, the son Section is the pavement branch sections that section divides according to setting partition value.
