Current navigation and positioning system for vehicles frequently be global GPS positioning system, which can provide for vehicle
The information such as three-dimensional position, speed and the time of all-weather, but it have the defects that it is certain: only unobstructed outdoor environment
Accurate, continuous navigator fix could be provided.Vehicle on-board remote control terminal covers GPS positioning module, location data it is upper
Report is equally also limited by GPS signal, and when passing through tunnel, viaduct or having high-rise to block, GPS positioning information be will be unable to
It collects.
Under the overall background of car networking big data operation, the location information of vehicle is effectively acquired, vehicle temperature can be formed
Facet figure, the distribution of vehicle real time position, so that carrying out analysis to client's active regions provides data for later period 0vehicle marketing operation
Support.TSP platform can also provide effective position when carrying out vehicular rescue service in the accurate location information of acquisition simultaneously.To the greatest extent
Breakdown lorry can be can be shortened and reach situ time.
Therefore, lack a kind of for utilizing car-mounted terminal when GPS signal is limited effectively to collect vehicle location
The method for carrying out described point positioning is modeled in conjunction with cloud platform data.
Also there are similar techniques at present, such as following discloses patent document:
Publication number: 108225341 A of CN, patent name " vehicle positioning method "；
Publication number: CN201610982478, " whether a kind of prediction vehicle position information closes the method and dress of rule to patent name
It sets "；
Above-mentioned document proposes the different system and methods for vehicle location information detection, but has common lack
Point:
1, the current GPS positioning of vehicle is uploaded by inertial navigation set end, by probability travel speed calculating location information,
Positioning accuracy is limited to the probability value calculated,；
2, monitoring data are only used for bicycle alarm, are a kind of waves to valuable data resource in car networking big data era
Take.
Summary of the invention
The technical problem to be solved by the present invention is to realize that a kind of pair of vehicle driving can not be obtained to the signals such as tunnel are bad
Under the operating condition of GPS signal, cloud server, cloud server, that is, vehicle connection are uploaded to by the vehicle-mounted terminal equipment data form of reissuing
It nets TSP platform and carries out data modeling by big data operation, described point is carried out to the location information of missing, obtains relatively accurate position
Set a kind of method of track.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of automobile described point localization method, including it is following
Step:
Step 1, vehicle launch state obtain current vehicle speed, steering wheel angle, GPS positioning data and data in real time and adopt
Collect the time, and is uploaded in the form of message data and gives car networking TSP platform；
Step 2 can not keep in the message data in the case of this under positioning scenarios when there is the bad GPS of signal；
Step 3, after GPS signal restores, when form free time that temporary message data is reissued, uploads to car networking
TSP platform, until temporary all message datas are reissued and finished；
Step 4, car networking TSP platform parse the message reissued, and are carried out according to the timestamp of message data acquisition
Sequence, calculates the opposite latitude and longitude value of GPS；
The opposite latitude and longitude value for calculating GPS is pushed to car owner's cell phone application or is shown in vehicle device by step 5.
In the step 2, when there is the bad GPS of signal and GPS is invalid, the latitude and longitude value of GPS is removed.
The message data further includes gear information and engine corner, rotary speed information.
A kind of system executing automobile described point localization method, comprising:
GPS: the device for vehicle location and navigation；
CAN communication module: for obtaining the device of vehicle operating parameters and GPS information by CAN bus；
Terminal control unit: vehicle operating parameters and GPS information are received, and carries out the device of data processing；
Wireless module: vehicle operating parameters and GPS information are sent to car networking TSP platform in the form of message；
ARM module: for keeping in the device of vehicle operating parameters and GPS information；
Multimedia unit: for showing and playing the device of navigation information.
The present invention is worked as by real vehicle CAN signal value speed, the calculating of the vehicles data combination car networking cloud platform such as angular speed
Preceding GPS is more accurate.
Detailed description of the invention
The content of width attached drawing every in description of the invention expression is briefly described below:
Fig. 1 is the block diagram for executing automobile described point localization method system.
Specific embodiment
The present invention is that the method based on the modeling of vehicle on-board terminal combination cloud platform data carries out described point localization method, is
System is as shown in Figure 1, comprising:
GPS: the device for vehicle location and navigation；
CAN communication module: for obtaining the device of vehicle operating parameters and GPS information by CAN bus；
Terminal control unit: vehicle operating parameters and GPS information are received, and carries out the device of data processing；
Wireless module: vehicle operating parameters and GPS information are sent to car networking TSP platform in the form of message；
ARM module: for keeping in the device of vehicle operating parameters and GPS information；
Multimedia unit: for showing and playing the device of navigation information.
Wherein GPS connects CAN communication module by CAN bus, and CAN communication module connects terminal control by signal wire
Device, terminal control unit connect wireless module by signal wire, and wireless module is used for telecommunication, flat with the car networking TSP of distal end
Platform wireless communication, ARM module are storage device, connect terminal control unit.
Described point localization method is as follows:
