Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Referring to Fig. 1, the present embodiment provides a kind of driver's driving efficiency points-scoring system, including following procedure main flow:
(1) stroke starts, and obtains dynamic changing data in real time and constructs driving efficiency scoring algorithm system, including driving
Sail technical ability, driving range and driving time；
Wherein, as shown in Fig. 2, the driving efficiency data are obtained by operation driving behavior algorithm, as shown in figure 3, institute
Stating driving efficiency includes sensing capability, judgement and control ability；
Sensing capability: mainly in the process of running, driver is to the geometric dimension of vehicle, one kind of operating status for vehicle
Feel control ability, it is specific to be divided into spatial perception ability, speed perception ability and environment sensing ability again；Spatial perception energy
Power, the i.e. sensing capability to vehicle dimension, peripheral space spacing.In car steering, due to the constraint by what comes into a driver's, to road
Observation is limited, can only be by estimating roughly.It is evaluated by three axis gravity plus the attitude mode of three shaft angle degree foundation；Speed
Spend sensing capability, the i.e. estimation during vehicle operation to speed.Since driver's relative vehicle is static, perception vehicle row
It sails speed and relies on outside scenery, so the perception being converted into scene change can be used here；Environment sensing ability, this is perception energy
The core of power judgement, that is, pass through the sensing capability (road surface fluctuation situation) of vehicle body attitude road pavement condition, believed by GPS longitude and latitude
Breath judgement is space environment (city, high speed, rural area), by vibration etc. to the sensing capability of vehicle, by weather conditions
Weather sensing capability (fine day, rainy, haze etc.).
Judgement: i.e. the judgement characteristic of the judgement characteristic of driver, driver varies with each individual.Driving experience and driving water
The problems such as difference of flat difference, perception velocities, the difference of fatigue driving, the difference driven when intoxicated and driving adaptability, all can shadow
Ring the pairing characteristic of driver.In influencing all qualities that driver judges characteristic, it is most important that driver is to road
The reaction and ability of attention of road situation variation.The respond of respond, driver has larger impact to traffic safety, choosing
Selecting the reaction time is the important psychological indicator for influencing traffic safety.Driver is longer to the reaction time of extraneous environmental stimulus, instead
Should be able to power it is poorer, be more easy to happen danger.Largely count later according to the operating time interval between each elemental motion element
Evaluation.Ability of attention, the ability of attention of driver also influence it and judge characteristic, pay attention to directive property, centrality and distributivity
Etc. features.In the process of moving, certain Traffic Information is directed toward and is concentrated on to driver psychology activity selectively to vehicle,
By the identification, judgement, choice of brain, correct driver behavior, guarantee driving safety are then taken.Ability of attention is to influence row
The important psychological factor of vehicle safety.
Control ability: driver realizes desired speed, direction etc. by control vehicle steering mechanism.Control ability is main
Refer to vehicle in the process of running, driver is in all cases to the manipulation ability of vehicle, including breaks the barriers, limits
Road, ramp drive, and feed speed control, lane change, jolts at turning.Superiority and inferiority and driving technology of the driver to vehicle operating ability
Superiority and inferiority evaluate.Manipulation ability is mainly manifested in terms of two of driver: 1: driver's driving behavior；2: driver drives
The ride comfort of vehicle.The driving efficiency of driver is showed with the two, this is the core of driver's driving efficiency appraisement system,
By the safety of behavior act, the ride comfort of driver behavior scores.
(2) driving efficiency scoring algorithm system threshold value is obtained according to vehicle environmental, detailed process is as shown in Figure 4；
The vehicle environmental includes that (vehicle mass, automobile rank, energy source type, starts at vehicle intake mode information of vehicles
Machine etc.), external driving environment (city, suburb, rural area, high speed etc.) and outside driving weather (fine day, rainy day, haze etc.).
(3) it is calculated according to driver's driving efficiency scoring algorithm and drives scoring, detailed process is as shown in Figure 5；
Driving scoring be divided into again skill scores, environmental protection scoring, safety scoring, fuel-efficient scoring and comprehensive score.
(4) scoring is driven according to driving efficiency, driving range, driving time real-time update；
Specifically, as shown in fig. 6, with driving range and driving time variation, at interval of five minutes update once drive
Scoring is sailed, or drives scoring encountering to change to update according to driving efficiency in special circumstances.
(5) change conditions for driving scoring pass through the real-time sending out notice of calling interface to client, detailed process such as Fig. 7 institute
Show；
(6) stroke terminates, and relevant information data can be entered into corresponding database, the number obtained including driving scoring
According to, the external environment of driver, ambient weather, factors, the detailed process such as threshold value used in judgement it is as shown in Figure 8；
(7) after stroke, client can obtain the driving scoring of this stroke, driver's driving efficiency comprehensive score and
Improving advice, respectively for user security, the scoring and suggestion of driving efficiency, fuel-efficient, environmentally friendly aspect, to supervise user
It was found that insufficient improve oneself driving efficiency, detailed process is as shown in Figure 9.
The above is merely preferred embodiments of the present invention, be not intended to restrict the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
