Introduction to the results:

The performance optimization of the powertrain of the entire vehicle not only involves the structural design of the entire vehicle and the optimization of the overall engine performance (the entire operating range), but more importantly, the optimization and matching of the powertrain (engine) and the transmission train (the entire vehicle). In the past, this key part was often ignored in vehicle development: either it did not attract enough attention, or simultaneous development was not achieved; there was no suitable evaluation system (especially comprehensive evaluation), testing and simulation calculations and design could not be coordinated, etc. Therefore, the performance of the entire vehicle's powertrain cannot reach the best state.

This project started in 1996. After more than 10 years of research, a comprehensive evaluation system for the powertrain has been established, and research has been carried out on the coordination of simulation calculations (commercial software) and test technologies (test benches and methods, national standards, etc.)., national and enterprise standards for powertrain design have been collected and sorted out, and a relatively complete, feasible and practical vehicle powertrain development system has been established. Scientific research projects commissioned by four domestic companies have been completed.

The "Comprehensive Evaluation System for Complete Vehicle Powertrains" proposed in this project has been verified by practical scientific research projects in cooperation with enterprises and has proved to be of theoretical significance and practical value for improving the comprehensive performance of the powertrain.

Some of the research results of this project,"Construction of a comprehensive performance evaluation system for a complete vehicle powertrain, coordination of simulation calculations and tests, and application in vehicle development", won the second prize for scientific and technological achievements in the automotive industry in 2006.
