Evaluation Method of Handling Force Feedback Comfort of Vehicle Gear Lever
摘要
Abstract
A method for evaluating handling comfort of vehicle gear laver was proposed based on its force feedback characteristics.The method combined the obj ective test with the subj ective evalua-tion,to compensate for the inadequacy of subj ective evaluation only.The variation of handling force feedback with the displacement of the gear lever and the driver’s individual differences were analyzed. The relative force feedback maxima and relative handling stiffness were extracted as obj ective indica-tors for the processes of gear selection,in-gear and out-of-gear.In addition,back propagation (BP) neural network was improved by particle swarm optimization (PSO),thereby an evaluation model was established, which described the mapping relationships between obj ective indicators and subjective scores.Finally,the model was trained and tested by 48 groups of sample data obtained from the handling experiments,which took the manual transmission used widely in normal car for exam-ples.The results show that the evaluation with proposed method is accurate and stable,so that it can provide guidance for optimization design of vehicle transmissions.关键词
