Abstract: In order to solve the current problem that most studies focus on the development of related hardware,communication protocol and upper computer software,too reliance on manual calibration parameters,the lack of automatic optimization calibration of the research problems, first by using an orthogonal trial design,the control parameter with great influence on the test index is selected as the input factor for the subsequent calibration. Secondly,a combined optimization algorithm is constructed to optimize the key parameters,with the combination of hardware and software,such as MicroAutoBox,Isight and MATLAB/Simulink,the automatic optimization calibration platform is designed. Finally,through the bench test verification,the automatic optimization calibration bench of new energy vehicles is built, the calibration time is reduced by 74.86 % compared with the manual calibration,realizing the high efficiency and automation of the calibration process. Under the target working condition,the power consumption of 100 kilometers is reduced by 4.3 % compared with that before the automatic optimization calibration.

Key words: new energy vehicle, bench model, orthogonal trial design, automatic optimization calibration system
