The flow chart of embodiment.The method includes：
S100, the speed limit for obtaining present road, and the current vehicle speed of vehicle is compared with the speed limit.
Specifically, the present road refers to the road of vehicle current driving.The current vehicle speed refers to vehicle
Real time running speed.The current vehicle speed can be obtained by the speedometer of vehicle self-carrying, can also pass through the GPS of vehicle configuration
Positioning system obtains.The speed limit refers to the legal speed limit of present road.In practical applications, in same path
Different sections of highway, speed limit may be different.For example, in one section of speed limit 60KM/h of certain road, pass through certain in this road
The stretch speed limit 30KM/h of school.Therefore the method fixed limit of the current road segment of present road is obtained when obtaining the speed limit
Speed value wants speed limit described in real-time update if the current speed limit obtained is different from the speed limit of upper a road section, is driven with prompt
The person of sailing avoids driver from exceeding the speed limit because ignorant.
According to national standard《Automobile speedometer》Regulation：The speed of speedometer must not be less than actual vehicle speed.Speedometer
Instruction speed and actual vehicle speed between should meet the relationship of " 0≤instruction speed-actual vehicle speed≤actual vehicle speed/10+4km/h "
Formula, as long as that is, the speed of the speedometer instruction of vehicle is in the section of defined.Thus different automakers produce
The travel speed of speedometer instruction is different so that the travel speed that the speedometer of the vehicle self-carrying of different manufacturers production show with very
Real speed has different degrees of difference, and the present speed to be obtained by vehicle speed table is inaccurate.And pass through GPS positioning system
The current vehicle speed obtained of uniting is consistent with the true speed of vehicle.For example, the speedometer that table 1 is the automobile of certain automaker production refers to
The comparison of the instrument speed, GPS map speed, vehicle true velocity shown.
As shown in Table 1, between the instrument speed and true velocity of the automobile there are the error of 6-8km/h, and GPS map speed
It is consistent with vehicle true velocity.Therefore, the present embodiment regard the speed obtained by GPS positioning system as the current traveling of vehicle
Speed, i.e. present speed.
Illustratively, the speed limit for obtaining present road, and the current vehicle speed of vehicle and the speed limit are carried out
It is more specific to may include：
S101, the speed limit that present road is obtained according to the map of the navigation device of vehicle configuration configuration；
S102, the present speed for obtaining vehicle in real time using the GPS positioning system of vehicle configuration, and by the present speed with work as
The speed limit of preceding road is compared.
Specifically, the map（Such as, Amap, Baidu map, Google Maps etc.）With according to residing for vehicle
Position be automatically positioned present road, and acquire the function of the speed limit of present road.The map can be shown in terminal and set
Standby display interface.The terminal device can be mobile terminal, can also be on-vehicle host.When the map obtains current road
After the speed limit on road, the speed limit is shown in any position of display interface.In the present embodiment, since Chinese vehicle is
Left handle drive knows the speed limit in order to facilitate driver, by the speed limit real-time display in a left side for the display interface
Upper angle.
Further, in order to prompt whether driver's current vehicle speed exceeds the speed limit, the display side of the speed limit can be pre-set
The correspondence of formula and current vehicle speed and the relationship of speed limit, so that subsequently can be according to the relationship of current vehicle speed and speed limit
Determine the display mode of the speed limit.In practical applications, the display mode Yu current vehicle speed and speed limit of the speed limit
The correspondence of relationship can be：When the current vehicle speed is less than the speed limit, shown using black surround and white font
Speed limit；When the current vehicle speed is more than the speed limit, speed limit is shown using red frame and red font.In this implementation
In variant embodiment, the speed limit can also be shown in other positions, for example, Dynamic Announce is on the present road, with
The vehicle is adapted in the route of the present road, and the speed limit of present road is noticed convenient for driver, is avoided
The case where hypervelocity being caused since driver is ignorant.
In the step S102, the present speed of vehicle is obtained in real time using the GPS positioning system of vehicle configuration, and will
The present speed is compared with the speed limit of present road.It, can after determining the comparison result of present speed and speed limit
To determine limit according to the correspondence between the relationship of pre-set present speed and speed limit and the display mode of speed limit
The display mode of speed value.For example, when the present speed is less than the speed limit of present road, it is aobvious using black surround and white font
Show speed limit, and continues to obtain the present speed of vehicle in real time；When the present speed is more than the speed limit, red frame is used
Speed limit is shown with red font and executes step S200.
S200, when the current vehicle speed be more than the speed limit when, record the overspeed of vehicle number.
Specifically, the hypervelocity number refers to that current vehicle speed is more than the number of the speed limit.If current vehicle speed is more than
The speed limit is primary, then the hypervelocity number accumulates once.It in practical applications, can be by pre-setting one for recording
The hypervelocity number counter passes through the hypervelocity number of vehicle described in the counters count.
Illustratively, described when the current vehicle speed is more than the speed limit, it is specific to record the overspeed of vehicle number
Including：
S201, a counter for recording overspeed of vehicle number is pre-set, and when current stroke starts, starts the meter
Number device；
S202, when the current vehicle speed be more than the speed limit when, the counter adds 1.
Specifically, the current stroke refers to described in this period of time from engine start to tail-off
The stroke of vehicle.The current stroke starts to refer to the engine start of the vehicle.
When the engine start of vehicle, current stroke starts, and starts the counter for being set to vehicle.In practical application
In, the counter can be with a MCU（Micro-control unit）Unit is connected, when the MCU receives what the map obtained
When the current vehicle speed that speed limit is obtained with the GPS system, the current vehicle speed is compared with the speed limit, and will compare
Relatively result is sent to counter.If current vehicle speed is more than speed limit, counter adds 1；If current vehicle speed is less than speed limit, count
Number device adds 0.
S300, overspeed of vehicle number in current stroke is obtained, and determines that the vehicle is driven according to the overspeed of vehicle number
Sail the first scoring of the drive safety in current stroke.
Specifically, overspeed of vehicle number refers in current stroke in the current stroke, and the counter records are tired out
The hypervelocity number added, for example, the cumulative hypervelocity number of counter records is 1 time, then overspeed of vehicle number is 1 in current stroke
It is secondary；The cumulative hypervelocity number of counter records is 3 times, then overspeed of vehicle number is 3 times in current stroke.First scoring
Refer to evaluating the score of vehicle drive safety in current stroke.The overspeed of vehicle number is more, described in explanation
First scoring is lower.
In the present embodiment, it for the ease of the drive safety in current stroke described in quantitative assessment, can pre-set
The correspondence of the vehicle first scoring and the overspeed of vehicle number of drive safety in current stroke.For example, institute
The full marks for stating the first scoring are 10 points, and when the overspeed of vehicle number is 0, corresponding first scoring is 10 points；When the vehicle
Hypervelocity number be 1 when, it is corresponding first scoring be 9 points；When the overspeed of vehicle number is 2, corresponding first scoring is 8
Point ... and so on, until first scoring is 0 point.Certainly, in practical applications, commented for the ease of statistics described first
Point, reduce calculation amount.Hypervelocity number can be divided into several sections, several sections correspond to one first scoring respectively,
For example, several sections are respectively [0], [1,2], [3,5], [6 ,+∞）, wherein [0] it is 10 points corresponding；[1,2] 6 points corresponding,
[3,5] corresponding 1 point, [6 ,+∞）It is 0 point corresponding.It is corresponding when hypervelocity number of the vehicle in current stroke is 4 times
First scoring is 1 point.By by the of hypervelocity number and drive safety of the vehicle in current stroke of current stroke
One scoring connects：When the hypervelocity number is fewer, corresponding, first scoring is higher, illustrates in current stroke
The safety of vehicle described in driver driving is higher, i.e., risk is lower, can warn driver at any time in this way, to pay attention to drive speed
It avoids exceeding the speed limit.
S400, preset time period all strokes for including are obtained, and according to the of the corresponding drive safety of all strokes
One scoring determines vehicle drive safety within a preset period of time.
Specifically, the preset time period referred in the effective date to the deadline of vehicle insurance for the vehicle insurance that the vehicle is handled
Time.For example, the effective date of the vehicle insurance is 2016.10.1, deadline 2017.10.1, then the preset time period is
For the one-year age in 2016.10.1-2017.10.1.All strokes that the preset time period includes are referred to described pre-
If all strokes that the vehicle carries out in the period.The stroke is starting with engine start, is knot with tail-off
Beam.Each stroke corresponds to one first scoring.It in the present embodiment, can be according to all strokes corresponding first
Scoring determines vehicle drive safety in the preset time period, and vehicle drive safety in the preset time period is carried out
Quantization means, in order to formulate the premium of adaptability.Therefore, all strokes for obtaining preset time period and including, and according to
First scoring of the corresponding drive safety of all strokes determines that vehicle drive safety within a preset period of time can specifically wrap
It includes：
S401, all strokes that preset time period includes are obtained, and determines that the first of the corresponding drive safety of each stroke comments
Point；
S402, the corresponding vehicle drive safety of the preset time period is determined using the method for weighting according to first scoring
Second scoring；
S403, vehicle drive safety within a preset period of time is determined according to second scoring.
Specifically, in the step S401, all strokes carry one first scoring respectively.Actually answering
In, all strokes for including in the preset time period can be ranked up sequentially in time, and respectively described in acquisition
The first scoring that all strokes carry obtains first scoring in sequence in this way, can influence to calculate to avoid repeating to obtain
As a result.
In the step S402, second scoring refers to the driving peace of the vehicle in the preset time period
The scoring of full property.By obtaining the number of all strokes, and according to the number and first scoring using weighting
Method determines that the corresponding vehicle drive safety second of the preset time period is scored.In the present embodiment, described second is determined
The process of scoring can specifically include：
H1, the number for obtaining all strokes；
H2, the first scoring summation of all strokes is obtained into the first summation to score of all strokes；
H3, the summation divided by the number are obtained into second scoring.
It sets second scoring to the scoring of drive safety of the vehicle in the preset time period, is used for
Evaluate drive safety of the vehicle in the preset time period.First scoring is higher, and the vehicle is described pre-
If in the period, i.e., the drive safety within the vehicle insurance effective date is higher, that is, it is lower to drive risk.It is main inside UBI vehicle insurances
Driving risk is judged according to the assessment result of driver's drive safety, and formulate corresponding premium.If described
Two scorings are low, illustrate that drive safety is low, correspondingly, drive risk and just will increase, will also formulate the strategy of additional premium；
It is on the contrary then reduce premium, encourage driver to strive for higher safety scoring, to promote more drivers are safer to drive
It sails.
Since hypervelocity number is more, drive safety is lower, therefore in practical applications, can also be according to driver in institute
The hypervelocity number in preset time is stated, makees different degrees of prompt to driver.For example, when drive safety is extremely low, it is described
The speed limit that display interface is shown starts flicker display, and excessive along with alarm prompt driver's hypervelocity number, drives peace
Full property is extremely low, pays attention to speed of operation, to improve the safety of driving.
In another embodiment of the present invention, overspeed of vehicle number in current stroke is obtained, and super according to the vehicle
Fast number determines that the vehicle drive further includes after the first scoring of drive safety in current stroke：
At the end of current stroke, the overspeed of vehicle number of the record is reset.
Specifically, since the judge of UBI vehicle insurances is based on the drive safety of this stroke and other risks and assumptions（It is anxious to add
Speed, anxious deceleration, zig zag etc.）, Comprehensive Evaluation is carried out, shows the score value of this stroke.Therefore this driving conditions China is super
Train number number will not be accumulated among stroke next time, and this hypervelocity number is only embodied in the record of this stroke；When driving
The person of sailing starts engine next time when, then it is considered as second stroke, the hypervelocity number of previous stroke then auto zero.
Certainly, in actually answering, the hypervelocity number of current stroke can also be obtained at the end of current stroke；At second
When stroke starts, continue cumulative hypervelocity number on the basis of the previous stroke of second stroke, and described second
At the end of a stroke, the hypervelocity number of second stroke is obtained；And so on, add up the hypervelocity number and is preset to described
Deadline in period.In this way, the vehicle can directly be assessed by the hypervelocity number of vehicle within a preset period of time
Drive safety, and adaptable premium policy is formulated with this.
