Abstract

Hybrid electric vehicle has three operating mode, depending on the operation of the engine and electric motor. According to the speed range of BLDC motor, In hybrid traction mode, both the engine and electric motor deliver to drive train. Battery charge mode, the electric motor operates as generator and is driven by the engine to charge the batteries. In engine alone traction mode, the electric motor is do-energized, and vehicle is propelled by the engine alone. we propose hysteresis current control technique to maintain constant speed in the motor load torque at the reverse direction. The proposed method is verified by using Matlab Simulink software.
