While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In a first embodiment of the invention, as shown in fig. 1, a vehicle powertrain model selection method of the invention includes the steps of:
step S210: the method comprises the steps of obtaining demand information of a vehicle to be constructed, and determining evaluation dimensions of a vehicle power assembly of the vehicle to be constructed and weighting coefficients corresponding to the evaluation dimensions according to the demand information.
In this embodiment, the vehicle to be constructed refers to a vehicle that has not been developed yet, the requirement information may be understood as index information for constructing the vehicle to be constructed, and the requirement information may be obtained according to a requirement of a customer. The evaluation dimensions of the vehicle powertrain include a plurality of dimensions, each evaluation dimension of the vehicle powertrain is determined by the type of the vehicle to be constructed, and the evaluation dimensions of the vehicle powertrains of different types of vehicles to be constructed are not necessarily the same, that is, the evaluation dimensions of the vehicle powertrains of different types of vehicles to be constructed are the same, and the evaluation dimensions of the vehicle powertrains of different types of vehicles to be constructed are different. The invention takes the example that the vehicle to be constructed is a minibus, and the evaluation dimensions of the vehicle power assembly of the minibus comprise PE performance, arrangement space (power source outline dimension), weight, NVH (noise, vibration, sound vibration roughness) performance, reliability, technical expansion capacity, accessory configuration (such as an adder, a compressor, a power takeoff and the like), supplier evaluation, development period, development expense, annual general capability and cost.
Specifically, after the demand information of the minibus is acquired, determining what each evaluation dimension specific parameter of the vehicle power assembly of the minibus is according to the demand information, for example, the weight is 1000-1150 KG. After obtaining each evaluation dimension of the vehicle powertrain of the minibus, the weighting coefficients corresponding to each evaluation dimension can be obtained. The weighting coefficients corresponding to the evaluation dimensions are preset, and are shown in table 1:
table 1: weighting coefficient table of evaluation dimension
| Serial number | Evaluation of dimensionality/Bi | Weighting coefficient/Qi | Serial number | Evaluation of dimensionality/Bi | Weighting coefficient/Qi |
| 1 | PE Properties | 0.14 | 7 | Accessory configuration | / |
| 2 | Arrangement space | 0.08 | 8 | Supplier evaluation | 0.07 |
| 3 | Weight (D) | 0.1 | 9 | Development cycle | 0.1 |
| 4 | NVH performance | 0.08 | 10 | Development fee | 0.08 |
| 5 | Reliability of | 0.15 | 11 | Ability to decline with age | 0.08 |
| 6 | Capability of technical development | / | 12 | Cost of | 0.12 |
Further, the step of acquiring the demand information of the vehicle to be constructed includes: acquiring a requirement description text of the vehicle to be constructed; and interpreting the requirement description text to obtain the requirement information. The requirement description text is generated by writing requirements to a template provided by a developer according to the requirements of the vehicle to be constructed by a customer. For example, the template may have a vehicle type item, if the vehicle to be constructed by the client is a minibus, the minibus may be filled in the vehicle type item, after the client fills the template, the template after filling the content is the requirement description text of the vehicle to be constructed, the requirement description text is interpreted to obtain the requirement information, and after the vehicle type item is interpreted, one of the information obtained is the minibus.
Step S220: and obtaining a vehicle powertrain design scheme related to the vehicle to be constructed.
Step S230: determining an evaluation score for each of the evaluation dimensions in the vehicle powertrain design.
In the embodiment, multiple vehicle powertrain design schemes related to the same type of vehicle to be constructed are preset, each vehicle powertrain design scheme corresponds to a group of evaluation dimensions of the vehicle powertrain of the type of vehicle to be constructed, each evaluation dimension corresponds to a specific parameter, each evaluation dimension with the specific parameter is related to an evaluation score, and the evaluation scores are obtained by a vehicle developer through combination of customer requirements and evaluation of multiple links such as technical evaluation, purchasing evaluation and financial evaluation.
Specifically, after determining the specific parameters of the evaluation dimensions of the vehicle powertrain of the minibus, a plurality of vehicle powertrain design schemes may be obtained from a plurality of vehicle powertrain design schemes associated with the minibus according to the specific parameters of the evaluation dimensions, and the evaluation scores of the evaluation dimensions in each vehicle powertrain design scheme may also be obtained. For example, 5 vehicle powertrain designs are obtained, and the evaluation scores of the respective evaluation dimensions in each vehicle powertrain design are shown in table 2:
table 2: evaluation score table of evaluation dimension
Step S240: and determining the feasibility score of the vehicle powertrain design scheme according to the evaluation score corresponding to the vehicle powertrain design scheme and the weighting coefficient.
Step S250: and selecting a target vehicle powertrain design scheme corresponding to the demand information according to the feasibility scores of the vehicle powertrain design schemes.
In this embodiment, step S240 includes performing weighted summation calculation on the evaluation scores corresponding to the vehicle powertrain design plan according to the weighting coefficients to obtain a feasibility score of the vehicle powertrain design plan. Specifically, the formula of weighted summation calculation is:
F-B1 × Q1+ B2 × Q2+ B3 × Q3+. + B11 × Q11+ B12 × Q12, wherein F represents a feasibility score of a vehicle powertrain design, B1, B2, B3,. said, B11, B12 sequentially represent PE performance, arrangement space, weight,. said, year-down capability, and cost, and Q1, Q2, Q3,. said, Q11, and Q12 sequentially represent a weighting coefficient corresponding to PE performance, a weighting coefficient corresponding to arrangement space, a weighting coefficient corresponding to weight,. said, a weighting coefficient corresponding to year-down capability, and a weighting coefficient corresponding to cost. Further, after the feasibility scores of the vehicle powertrain design schemes are calculated by adopting the formula, the feasibility scores of all the vehicle powertrain design schemes are ranked, the maximum feasibility score is selected from the ranking results, and the vehicle powertrain design scheme corresponding to the maximum feasibility score is used as the target vehicle powertrain design scheme corresponding to the demand information, namely the scheme finally selected.
According to the technical scheme, the method comprises the steps of obtaining demand information of the vehicle to be constructed, determining evaluation dimensions of the vehicle power assembly of the vehicle to be constructed and weighting coefficients corresponding to the evaluation dimensions according to the demand information, obtaining a vehicle power assembly design scheme related to the vehicle to be constructed, determining evaluation scores of the evaluation dimensions in the vehicle power assembly design scheme, determining feasibility scores of the vehicle power assembly design scheme according to the evaluation scores and the weighting coefficients corresponding to the vehicle power assembly design scheme, and selecting a target vehicle power assembly design scheme corresponding to the demand information according to the feasibility scores of the vehicle power assembly design scheme.
As shown in fig. 2, in the second embodiment of the present invention, step S250 includes the steps of:
step S251: judging whether an infeasible scheme exists in each vehicle powertrain design scheme, and if so, executing step S254; if not, step S252 is performed.
Step S252: ranking the feasibility scores for each of the vehicle powertrain designs;
step S253: and determining a target vehicle powertrain design scheme corresponding to the demand information according to the vehicle powertrain design scheme corresponding to the maximum feasibility score.
Step S254: filtering out the infeasible solutions from each of the vehicle powertrain designs, and executing step S252.
In this embodiment, the preset multiple vehicle powertrain design schemes associated with the same type of vehicle to be constructed not only include feasible schemes and infeasible schemes, the feasible schemes are implementable, and the infeasible schemes are not implementable, so after the specific parameters of each evaluation dimension of the vehicle powertrain of the minibus are determined, the obtained vehicle powertrain design schemes may also include infeasible schemes according to the specific parameters of each evaluation dimension, and even if the scores of the infeasible schemes are high and are selected as the target vehicle powertrain design scheme, the infeasible schemes cannot be implemented. Therefore, it is necessary to determine whether there is an unfeasible solution among the acquired vehicle powertrain designs.
Specifically, whether an infeasible scheme exists in each vehicle powertrain design scheme is judged, if the infeasible scheme does not exist, the obtained vehicle powertrain design schemes are all feasible schemes, the feasibility scores of the vehicle powertrain design schemes are sorted, the maximum feasibility score is selected from the sorting results, and the vehicle powertrain design scheme corresponding to the maximum feasibility score is used as the target vehicle powertrain design scheme corresponding to the demand information. If so, filtering the infeasible schemes from the vehicle powertrain design schemes, and if so, keeping all the feasible schemes, then executing step S252, that is, sorting the feasibility scores of the feasible schemes, selecting the maximum feasibility score from the sorting results, and taking the feasible scheme corresponding to the maximum feasibility score as the target vehicle powertrain design scheme corresponding to the demand information, that is, taking the vehicle powertrain design scheme corresponding to the maximum feasibility score as the target vehicle powertrain design scheme corresponding to the demand information.
Further, the step of determining whether there is an infeasible solution in each of the vehicle powertrain designs includes:
traversing each of the vehicle powertrain design scenarios;
determining the traversed vehicle powertrain design scheme as an infeasible scheme when the traversed vehicle powertrain design scheme has an evaluation dimension with an evaluation score less than or equal to a preset value;
and when the evaluation scores of all the evaluation dimensions in the traversed vehicle powertrain design scheme are larger than a preset value, determining the traversed vehicle powertrain design scheme as a feasible scheme.
Specifically, the evaluation score may be represented by a score of 10, a score of 10 indicates a full score indicating complete agreement, a score of 6 indicates a passing line for evaluating the score, a score of 5 indicates that the solution (low risk) can be achieved by business negotiation and technical optimization, a score of 5 requires attention, and a score of 0 indicates that the solution is completely infeasible and can be directly excluded. On this basis, the preset value is set according to the lower score of the evaluation score, i.e. between 5 and 0, typically the preset value is set to 0. Assume that 5 vehicle powertrain design scenarios are obtained, which are scenario 1, scenario 2, scenario 3, scenario 4, and scenario 5, respectively. And traversing from the scheme 1, comparing the evaluation scores of all the evaluation dimensions in the scheme 1 with preset values when traversing to the scheme 1, wherein if the evaluation scores of all the evaluation dimensions in the scheme 1 are all larger than 0, the scheme 1 is a feasible scheme, and if the evaluation scores of any one evaluation dimension in the scheme 1 are all smaller than or equal to 0, the scheme 1 is an infeasible scheme. After the judgment of the scheme 1 is completed, whether the schemes 1 to 5 are feasible schemes is sequentially judged according to the judgment mode of the scheme 1, which is not described in detail. Referring to table 2, if the evaluation score of the arrangement space of case 4 is 0, case 4 is not a feasible case.
According to the technical scheme, the technical means of filtering the unavailable scheme is adopted to select the design scheme of the power assembly of the target vehicle, so that the selection efficiency of the design scheme of the power assembly of the target vehicle is improved.
As shown in fig. 3, in the third embodiment of the present invention, step S253 includes the steps of:
step S2531: acquiring the number of vehicle powertrain design schemes corresponding to the maximum feasibility scores in the vehicle powertrain design schemes;
step S2532: judging whether the number is single, if so, executing a step S2533; if not, step S2534 is performed.
Step S2533: and taking the vehicle powertrain design scheme corresponding to the maximum feasibility score in the vehicle powertrain design schemes as a target vehicle powertrain design scheme corresponding to the demand information.
Step S2534: screening out a vehicle powertrain design scheme corresponding to the maximum feasibility score;
step S2535: and taking the vehicle powertrain design scheme with the maximum evaluation score and corresponding to the evaluation dimension which is the same as the preset evaluation dimension in the screened vehicle powertrain design schemes as the target vehicle powertrain design scheme corresponding to the demand information.
In this embodiment, after calculating the feasibility scores of each implementable vehicle powertrain design, there may be a plurality of vehicle powertrain designs with the largest feasibility scores, but only one vehicle powertrain design needs to be selected as the target vehicle powertrain design corresponding to the demand information. Based on this, the choice of single and multiple vehicle powertrain designs with the greatest feasibility score is preset.
Specifically, after the feasibility scores of the various implementable vehicle powertrain designs are ranked, the number of the vehicle powertrain designs corresponding to the maximum feasibility score is obtained from the ranking results, and if the number is single, the vehicle powertrain design corresponding to the maximum feasibility score in the ranking results is used as the target vehicle powertrain design corresponding to the demand information. If the number of the vehicle powertrain design schemes is multiple, the vehicle powertrain design scheme corresponding to the maximum feasibility score is screened, and then the vehicle powertrain design scheme corresponding to the evaluation dimension which has the maximum evaluation score and is the same as the preset evaluation dimension in the screened vehicle powertrain design schemes is used as the target vehicle powertrain design scheme corresponding to the demand information. The maximum feasibility score is a feasibility score which is arranged in the front of the ranking result and has a difference with an adjacent feasibility score in a preset range, and the preset evaluation dimension is comparison information used for deciding a final selection scheme when a plurality of vehicle powertrain design schemes corresponding to the maximum feasibility scores exist.
If 5 vehicle powertrain designs are obtained, a feasibility score for each vehicle powertrain design can be calculated, as shown in table 3.
Table 3: feasibility score for vehicle powertrain design
For example, the preset range is 0 to 0.05, the preset evaluation dimension is the annual degradation capability, referring to tables 2 and 3, the difference between the feasibility scores of the scheme 1 and the scheme 2 is 0.05, and within the preset range, the feasibility scores of the scheme 1 and the scheme 2 are the maximum feasibility scores, that is, 2 vehicle powertrain design schemes corresponding to the maximum feasibility scores exist in 5 vehicle powertrain design schemes, and then the evaluation score of the annual degradation capability in the scheme 1 and the evaluation score of the annual degradation capability in the scheme 2 are compared, wherein the evaluation score of the annual degradation capability in the scheme 1 is 6, the evaluation score of the annual degradation capability in the scheme 2 is 7, and the scheme 2 is selected as the target vehicle powertrain design scheme corresponding to the requirement information.
