Abstract

In this paper, the modelling of AMT-HEV(automated manual transmission hybrid electric vehicle) and Planetary-HEV is performed , and a modified shift control algorithm is proposed to improve the shifting performance at changing mode. The driving simulation is carried out with various driving conditions in order to investigate the response characteristics of HEV with respect to transmission type. HEV powertrain model consists of the internal combustion engine, electric motor, battery, planetary gear, automated manual transmission and the regenerative braking system using MATLAB. In addition, a regenerative control algorithm is suggested considering the battery SOC. In this paper, the modelling of AMT-HEV and Planetary-HEV is performed by using MATLAB, the response characteristics of AMT-HEV is compared with the response characteristics of Planetary-HEV at changing mode.

Key words : HEV, AMT, Planetary gear, SOC, Regenerative Braking
