Combinatory Optimization Of The Vehicle Handling And Stability

The linear vehicle open-loop system and driver-vehicle close-loop system is studied in this paper. A new combinatory evaluation index about handling and stability of open-loop and close-loop system is presented. Further more, the handling and stability of the open-loop and close-loop system is combined to optimize. The main purposes of this paper are:1. Based on the handling and stability evaluation indexes of open-loop system, a new combinatory evaluation index about handling and stability is presented. Further more, a general evaluation index Aopen is presented in order to considering the importance of the different speed.2. By the simulation of the vehicle open-loop system, using complex method matches the vehicle structure parameter.3. Based on the handling and stability evaluation indexes of the driver-vehicle close-loop system, a new combinatory evaluation index about handling and stability is presented. Further more, a general evaluation index Aclose is presented in order to considering the importance of the different speed.4. By the simulation of the driver-vehicle close-loop system, using complex method matches the vehicle structure parameter.In conclusion, some inherent rules and relations of motion stability of the open-loop system and the driver-vehicle closed-loop system are revealed in this paper. The results of simulation and optimization about the open-loop system and driver-vehicle close-loop system indicate the index and the method presented are right and valuable.
