Study of Dual Motor System for EV (Second Report)

- Proposal of New System Control Method -

Abstract

This paper proposes a new control method for a large EV drive system that combines conventional motors and planetary gears. The system output torque and the difference between the two motor speeds are the target values. This controller was created by system models to enable coordinated control of the two motors. The proposed new control method was verified using a test bench in comparison with the conventional control method. The results confirmed that, unlike the conventional control method, the proposed new control method can switch modes and perform other actions without generating driving force shock.
