Embodiment bis-

The present embodiment provides a kind of method of definite driving range, and the method is by determining in conjunction with road informationThe actual travel scope of vehicle, and then improve the accuracy of definite driving range. In conjunction with above-described embodiment oneContent, referring to Fig. 2, the method flow that the present embodiment provides is specific as follows:

201: the maximum driving range of theory of determining vehicle;

Particularly, the specific implementation of this step has two kinds, and the first implementation is according to prior artDetermine theoretical maximum driving range according to the vehicle data collecting; The second implementation is collection vehicle numberAccording to, and obtain factor of influence according to traffic impact data and/or user behavior data, according to the vehicle collectingData and the factor of influence getting are determined theoretical maximum driving range.

Wherein, the vehicle data collecting in the first implementation and the second implementation includes but notBe limited to the data such as vehicle performance parameter and accumulator electric-quantity, in practical application, this vehicle data can be by automobile factoryBusiness provides, and pre-stored in corresponding vehicle data storehouse. By being connected with vehicle data storehouse, enterAnd can collect the wherein vehicle data of storage. Certainly, in addition, can also there be other collection vehicleThe mode of data, the present embodiment is not done concrete restriction to this.

For in the second implementation according to traffic impact data acquisition factor of influence, according to the car collectingData and the factor of influence getting are determined the mode of theoretical maximum driving range, this traffic impact packetDraw together but be not limited to the data that obtain according at least one influence factor in weather conditions, season, traffic slot,It equally can be pre-stored in corresponding traffic impact database, by connecting with traffic impact databaseConnect, can therefrom collect traffic impact data. Certainly, in addition, can also there be other to gather traffic shadowRing the mode of data, for example, also can, according to real-time traffic situation Real-time Collection traffic impact data, specifically adoptWhich kind of mode gathering traffic impact data by, the present embodiment is not done concrete restriction equally to this. Which no matter adoptsThe mode of kind collects after traffic impact data, all the traffic impact data transaction collecting can be become to corresponding shadowRing the factor. For example, the data instance taking traffic impact data as obtaining according to weather conditions, can count pinTo the energy consumption of vehicles (E under this kind of weather conditions_W), then in conjunction with the standard energy consumption (E of vehicle_S), by E_W/E_SBe defined as factor of influence.

The vehicle data collecting in basis and the factor of influence arriving according to traffic impact data acquisition are determined theoreticalWhen maximum driving range, include but not limited to first utilize the side that determines theoretical maximum driving range in prior artFormula, obtains the maximum driving range X of a standard theory according to the vehicle data collecting_max, then in conjunction with impactThe maximum driving range of theory that the factor obtains determining, the maximum driving range of this theory can pass throughX_amax=(E_W/E_S)*X_maxRepresent. Taking the maximum driving range of the theory shown in Fig. 3 (1) as example, this Fig. 3(1) the maximum driving range of border circular areas representation theory in.

For obtaining factor of influence according to user behavior data in the second implementation, according to the car collectingData and the factor of influence getting are determined the mode of theoretical maximum driving range, this user behavior data bagDraw together but be not limited to user's driving behavior data and/or driver behavior data, it equally can be pre-stored in correspondenceUser behavior data storehouse in, by being connected with user behavior data storehouse, can collect wherein storageUser behavior data. Certainly, in addition, can also there be other modes that gathers user behavior data,For example, driving behavior data and/or the driver behavior data also can Real-time Collection inputted by user, specifically adoptWhich kind of mode gathers user behavior data, and the present embodiment is not done concrete restriction equally to this. Which kind of no matter adoptsMode collects after user behavior data, all can impact corresponding to the user behavior data collecting convert toThe factor. For example, the driving behavior data instance taking user behavior data as user, can count for this kindVehicle Driving Cycle energy consumption (E under user's driving behavior data_u), then in conjunction with the standard energy consumption (E of vehicle_S），By E_u/E_SBe defined as factor of influence.

Further, user behavior data can also comprise the travel direction that user specifies, and this step is at rootObtaining theoretical maximum according to the vehicle data collecting and the factor of influence that gets according to user behavior data travelsAfter scope, also comprise: the travel direction of specifying according to user is determined the angle of travelling, and according to the angle of travellingAdjust the maximum driving range of definite theory.

The maximum driving range of theory that the vehicle data collecting with basis and the factor of influence getting are definiteX_amax=(E_u/E_S)*X_maxScope as shown in the border circular areas in Fig. 4 (1) is example, in user behavior dataThe travel direction that user specifies can be as shown in the point of right side edge in Fig. 4 (2), and that specifies according to user travelsThe orientation determination angle of travelling, and can be as Fig. 4 (3) according to the maximum driving range of the definite theory of the angle adjustment of travellingIn sector region shown in. Can find out by this process, owing to having considered that in user behavior data, user refers toFixed travel direction, the maximum driving range of theory after adjustment is less than the maximum driving range of unadjusted theory,Thereby subsequent step is in the time determining actual travel scope according to the maximum driving range of the theory after adjusting, and can reduceAmount of calculation, improves the speed of determining actual travel scope.

Certainly,, except the mode of the maximum driving range of above-mentioned several definite theory, also can adopt other to determineThe mode of theoretical maximum driving range, for example, determines theoretical maximum driving range according to the running time of vehicleDeng, which kind of specifically adopts determine the mode of theoretical maximum driving range, the present embodiment is not done concrete restriction to this.

In addition, no matter be above-mentioned Fig. 3 or Fig. 4, each lines in figure can identify each section, linesThickness can represent the traffic in section, for example, lines representative relatively thick in Fig. 3 or Fig. 4 shouldSection relatively blocks up, and relatively thin lines represent that this section is more unobstructed. In addition, can also be differentColor represents the traffic in section, for example, represents that section seriously blocks up, with yellow line with red linesRepresent that section relatively blocks up, represent that with green lines section is very unobstructed etc. Certainly, can also take itThe mode of the expression mode in his section and expression road section traffic volume situation, the present embodiment is not done concrete restriction to this.

202: the road information that obtains each section in theoretical maximum driving range;

Wherein, each section in theoretical maximum driving range is by each road in the maximum driving range of theoryPoint composition, two adjacent road points form a section, and the road information in each section includes but not limited to roadThe information such as the distance, category of roads, traffic of section, and category of roads includes but not limited to through street, friendshipProng and trunk roads etc., that traffic includes but not limited to is very unimpeded, unimpeded, slightly block up, moderate is gathered aroundBlock up, seriously block up etc.; According to transport information, speed limiting information, historical speed information, road shape letterBreath, road grade information, traffic control equipment information etc. all can obtain corresponding traffic.
