In real time driving behavior quality appraisal procedure.
Background technology:
Traffic accident is all often as caused by all kinds of violation driving behaviors, so vehicle drive behavioural analysis is traffic prison
One important research content in control field.At present, with the continuous development of the emerging information technology such as smart city, car networking, get over
The Big Dipper or GPS positioning system are mounted with come more vehicles, data are by endlessly caused by these vehicle positioning systems
Vehicle monitoring platform is sent to, is played an important role for the monitoring and risk-aversion of vehicle.From the vehicle-mounted Big Dipper or GPS numbers
Mainly have according to the common violation driving behavior that can be analyzed:Hypervelocity behavior, zig zag behavior, anxious acceleration behavior and the anxious row that slows down
For, nighttime driving behavior and fatigue driving behavior etc..How these violation driving behavior information are scientifically utilized, so as to objectively
The quality of vehicle drive behavior is assessed, is had broad application prospects.
The content of the invention:
It is an object of the invention to provide a kind of good and bad assessment side of the real-time driving behavior of vehicle based on the Big Dipper or gps data
Method, the real-time driving behavior quality appraisal procedure of the described this vehicle based on the Big Dipper or gps data will solve prior art
In fail to assess the good and bad technical problem of car steering behavior using these violation driving behavior data.
The invention provides a kind of real-time driving behavior quality appraisal procedure of vehicle based on the Big Dipper or gps data, bag
Include following steps:

Driving behavior then subtracts corresponding score value, then the last real time comprehensive scoring for just obtaining Current vehicle driving behavior, the scoring mould
Type is specific as follows:
D=100- (0.135x1+0.168x2+0.205x3+0.191x4+0.06x5+0.24x6)。
Further, using tyRepresent the night running time be in order to following tired time tpDistinguish because this two
The individual time is different, tyIt is the cumulative time calculated since 20 points to represent the night running time, and tpThe fatigue driving time is represented,
Time started is any time.
Further, the cycle of data acquisition is 30 seconds in step 1).
Further, the previous cycle in step 3), step 4), step 5) is the data of collection before 25~35 seconds.
Further, the previous cycle in step 3), step 4), step 5) is the data of collection before 30 seconds.
The previous cycle refers to, vehicle GPS data are the real time datas of periodic collection vehicle, the cycle one of data acquisition
As be 30 seconds, such as:14:00:00 receives a gps data, then and 14:00:30 can receive a gps data again, then before
One cycle referred to 14:00:The data that 00 that time receives.
Six kinds of common violation driving behaviors can be analyzed based on the vehicle-mounted Big Dipper or GPS device data:Hypervelocity behavior, urgency
Turning behavior, anxious acceleration behavior, anxious deceleration behavior, nighttime driving behavior and fatigue driving behavior.Disobeyed because this six kinds common
Rule driving behavior it is different degrees of have impact on the quality of vehicle entirety driving behavior, so giving this six kinds of violation driving behaviors distribution
Different weights, and this six kinds of individual event driving behavior score values are substituted into vehicle drive behavior real time comprehensive Rating Model, you can
Draw the good and bad real-time score value of the current driving behavior of reflection vehicle.
