Abstract:
This study proposes a control strategy to improve the energy recovery during the regenerative braking process of a pure electric bus and to ensure brake safety and maximum braking efficiency. By considering the battery state of charge (SOC) value and the motor speed, this strategy aims to distribute the friction braking force among the front and rear wheels according to a fixed ratio; the difference between the I curve and the β line shows the regenerative braking force. This strategy is embedded into the “ADvanced VehIcle SimulatOR” (ADVISOR) simulation platform and uses the New European Driving Cycle (CYC_NEDC) for simulation. The simulation results show that the proposed control strategy achieves braking energy recovery rate of 17.4%, which suggests effective recovery of energy.
