Platform-Based Design of the Hybrid Electirc Drive Load Spectrum

Ruan, Xiane / Li, Manli / Lei, Jun / Kang, Huajun / Liu, Huan

Hybrid electric drive assembly is currently a relatively new configuration in China, there are a variety of working modes such as driving, power generation and energy recovery, and there are also different working strategy in each mode. Various modes involve more factors, and the calibration of the real vehicle has a great impact on the load distribution, resulting in complex prediction of the load spectrum of each mode. Based on the basic theory of hybrid electric drive, combined with the actual vehicle projects and the distribution characteristics of measured data, the load generation mechanism and distribution of each mode were analyzed, and the load spectrum of each mode was quantified and compared. Based on the distribution strategy of each mode, and platform stratagem was considered, and the special load spectrum envelope design method was constructed for each mode, and the hybrid load spectrum construction method covering multiple vehicle platforms was generated.
