Problems solved by technology

[0002] When evaluating the performance of a vehicle, people often make certain evaluations on a certain aspect of the vehicle's performance, but the quality of the whole vehicle, especially the vehicles of different models and levels, is not easy to professionally evaluate. At present, domestic There is no objective overall vehicle evaluation method
At the same time, professional vehicle reviewers cannot establish an abstract overall data associated with real performance when evaluating various aspects of the vehicle, lack a complete set of vehicle dynamic performance and economic performance data analysis methods, and cannot quickly compare different configurations , The real performance of different models of vehicles
Non-professionals cannot quickly and intuitively understand the professional performance calculation and evaluation of vehicles

Embodiment 1

[0020] A method for objectively evaluating the power economy performance of a passenger car, said method comprising the following specific steps:

[0021] Step 1: Collect the dynamic index and economical index of the passenger car respectively. The dynamic index includes: the first gear gradeability (%) index result1, the second gear gradeability (%) index result2, and the second-grade gradeability index (%) index result3, the highest grade grade (%) index result4, the highest speed index result5, the 0-90km / h acceleration time (s) index result6 and the direct gear 40-80km / h acceleration time (s) index result7, so The above economic index result is the vehicle C-WTVC fuel consumption data (1 / 100km) index.

[0022] Step 2: Set the upper limit value i100 and the lower limit value i60 respectively for the setting of the limit value of the passenger car dynamic index and economic index;

[0023] The upper limit value i100 of the passenger car dynamic index is 1.05 times the optim...

Embodiment 2

[0035] A method for objectively evaluating the power economy performance of a passenger car, said method comprising the following specific steps:

[0036] Step 1: Collect the dynamic index and economical index of the passenger car respectively. The dynamic index includes: the first gear gradeability (%) index result1, the second gear gradeability (%) index result2, and the second-grade gradeability index (%) index result3, the highest grade grade (%) index result4, the highest speed index result5, the 0-90km / h acceleration time (s) index result6 and the direct gear 40-80km / h acceleration time (s) index result7, so The above economic index result is the vehicle C-WTVC fuel consumption data (1 / 100km) index.

[0037] Step 2: Set the upper limit value i100 and the lower limit value i60 respectively for the setting of the limit value of the passenger car dynamic index and economic index;

[0038] The upper limit value i100 of the passenger car dynamic index is 1.05 times the optim...

Abstract

The invention discloses a method for performing objective evaluation on power performance and economic performance of a passenger car. The method particularly comprises the following steps: 1, acquiring and calculating the power performance index and the economic performance index of the passenger car separately; 2, setting the limiting values of the power performance index and the economic performance index of the passenger car; 3, calculating an objective score value Vdi of each power performance index separately; 4, setting a weight value Wi of each power performance index; 5, calculating final evaluated power performance value Score d of the vehicle; 6, calculating the final evaluated economic performance value Score c of the vehicle; and 7, evaluating the integrated performance of the vehicle by objective data. By the method, the abstract performance indexes and data of the vehicle as well as the actual performance of the vehicle can be related well; furthermore, through calculation and combination of various data, the actual performance of different configuration or different vehicle types can be compared rapidly and objectively, and numerical value embodied objective evaluation can be conducted.

Description

technical field [0001] The invention relates to the field of passenger car power and economic performance evaluation, and more specifically relates to a method for objectively evaluating the passenger car power and economic performance. Background technique [0002] When evaluating the performance of a vehicle, people often make certain evaluations on a certain aspect of the vehicle's performance, but the quality of the whole vehicle, especially the vehicles of different models and levels, is not easy to professionally evaluate. At present, domestic There is no objective overall vehicle evaluation method. At the same time, professional vehicle reviewers cannot establish an abstract overall data associated with real performance when evaluating various aspects of the vehicle, lack a complete set of vehicle dynamic performance and economic performance data analysis methods, and cannot quickly compare different configurations , The real performance of different models of vehicl...
