China automotive test cycle - Part 1.Light-duty vehicles1 ScopeThis Part of GB/T 38146 specifies the construction of the test cycle of light-duty vehicles (including passenger cars and light-duty commercial vehicles). This Part applies to M1 and N1 type vehicles, M2 type vehicles with a maximum design total mass not exceeding 3500 kg.2 Normative referencesThe following documents are indispensable for the application of this document. For the dated references, only the editions with the dates indicated are applicable to this document. For the undated references, the latest edition (including all the amendments) are applicable to this document. GB/T 3730.1 Motor vehicles and trailers - Types - Terms and definitions GB/T 15089 Classification of power-driven vehicles and trailers3 Terms and definitionsThe terms and definitions defined in GB/T 3730.1 and GB/T 15089 and the following ones apply to this document. 3.1 Light-duty vehicle M1 and N1 type vehicles, M2 type vehicles with a maximum design total mass not exceeding 3500 kg. 3.2 China automotive test cycle The time-speed curve which describes the driving characteristics of a particular vehicle (such as a passenger car, a commercial vehicle, a city bus, etc.) in a Chinese traffic environment. 3.3 China light-duty vehicle test cycle; CLTC The general term for China automotive test cycle used by M1 and N1 type vehicles, M2 type vehicles with a maximum design total mass not exceeding 3500 kg.4 Cycle construction4.1 Overview China light-duty vehicle test cycle includes China light-duty vehicle test cycle for passenger car and China light-duty vehicle test cycle for commercial vehicle. 4.2 China light-duty vehicle test cycle for passenger car China light-duty vehicle test cycle for passenger car (CLTC-P) includes 3 speed intervals. 4.3 China light-duty vehicle test cycle for commercial vehicle China light-duty vehicle test cycle for commercial vehicle (CLTC-C) includes 3 speed intervals.Appendix A(Normative) Data of China light-duty vehicle test cycle A.1 The CLTC-P cycle data is shown in Table A.1.Appendix B(Normative) General method for development of China automotive test cycle B.1 General rule for development method of cycle This method is a summary of the technical route development of China automotive test cycle, including links such as test planning, data acquisition and processing, weighting factor development, cycle synthesis, cycle verification, mainly serving the development of automotive test cycle. B.2 Test planning B.3 Data acquisition and processing B.3.1 USE the free driving method to continuously collect the vehicle running data in the corresponding city (The acquisition frequency is not less than 1 Hz). The acquisition time is not less than 3 months. B.3.2 The acquisition parameters include vehicle position information, power drive system information, battery information, emission and environmental information. Through the vehicle terminal, the collected vehicle-related parameter information is arranged according to the unified data protocol, and through the communication network, sent to the remote data platform in real time and synchronously. B.4 Weighting factor development B.4.1 GET the low-frequency dynamic traffic volume big data of the corresponding city (the average speed of the road every five minutes). B.4.2 Establish a speed-flow model. USE the obtained low-frequency dynamic traffic big data to calculate the total travel time of the corresponding driving fleet on each city road network. Establish the changing trend of the total travel time with the average speed. The speed-flow relationship is. B.6 Cycle verification B.6.1 The statistical analysis of the characteristic difference between the constructed cycle curve and the actually-collected data is carried out, to determine the rationality of the cycle construction. B.6.2 Based on the vehicle hub bench, the followability of the constructed cycle is verified, to determine the operability of the cycle curve. B.6.3 Based on the existing test procedures, through the bench verification, the influence of the cycle curve on the service indicators is analyzed, to determine the final cycle curve. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
