In order to achieve synchronous shift on heavy-duty AMT (Automated Mechanical Transmission) without synchronizer, shift process analysis based on three-phase induction motor is proposed in the paper. On the basis of analysis for the speed loss of the transmission output shaft during shift process, the synchronous shift control strategy for AMT without synchronizer driven by three-phase induction motor is put forward for both upshift and downshift program. Estimation algorithms of the load equivalent inertia and the load equivalent resistance torque at the transmission output shaft are proposed to best meet the synchronous shift control. In view of similarity between the start-up process of the vehicle and that of the belt conveyor, AMT without synchronizer based on three-phase induction motor is applied to driving the belt conveyor. Simulation results prove that the strategy of synchronous shift control is effective during upshift process and downshift process.
