某乘用车电子换挡手感评价体系建立

Establishment of an Evaluation Eystem for the Electronic Shift Feel of a Passenger Car

某款杆式电子换挡器上市后,市场反馈换挡器手感不佳引起客户抱怨。因此需要对换挡手感进行优化提升。通过对手感分析,建立了换挡手感主、客观评价体系,对换挡手感各影响因素确定了优化目标。根据目标值对某款电子换挡器进行结构优化,优化后的换挡器样件装车后进行效果评价,得到评价团队及市场的一致认可,相关投诉明显减少。通过建立换挡手感体系,能够有效的评价出换挡手感的优劣,为电子换挡器手感优化奠定了坚实的基础。

After one stick-shifter was launched for the market,customer’s complaints related to the shift feeling in a high frequency.Therefore,optimizing the shift feeling is necessary,establishing one theory includes objective and subjective evaluation methods,define the optimization targets.And then optimize the structure acc.To the optimization targets in this theory.After all the engineering optimization,one physical prototype was made.And it was assembled in one brand-new car,and evaluation activity was held for it.Received highly satisfaction from the evaluation team and the market finally.By this objective and subjective evaluation system,the advantages and disadvantages could be filtered effectively,and enhancing the key-points for the electronic shifter research and development.
