Abstract
As environmental regulations are strengthened around the world, the application of eco-friendly vehicles such as electric vehicles is expanding in the existing small vehicle models. In addition, since commercial vehicles generate a lot of exhaust gas, the importance of technology development for eco-friendly electric vehicles is on the rise. In this paper, a 6-speed transmission exclusively for electric vehicles applied with dual motors was analyzed. The two motor output shafts installed in this system have different gear ratios for each shift stage, so the load level for each motor is different according to the shift stage. To minimize energy consumption, torque distribution between the two motors and control for optimizing shift timing are required. In this paper, a method for optimal power control of the developed E-axle system was derived and verified by simulation.
