Experiment study and control strategy simulation on powertrain for an electric bus

On the basis of parameters matching for powertrain of an electric bus and its key components experiment verification, powertrain control system was focused designed and studied. The control strategy of driving torque and motor overload protection were developed, the method of battery power management was confirmed, in accordance with vehicle brake system, a combined strategy of mechanical and electrical regenerative braking was determined. Application of Matlab/simulink and ADVSIOR software, vehicle modeling and performance simulation analysis were carried out and the control strategy was verified. The simulation results show that the developed control strategy for the electric bus is applicable for vehicle drive control and energy management, the proposed regenerative braking control algorithm can increase vehicle drive range effectively in different driving conditions.
