Based on the structural features of electric vehicle (EV) driven by in-wheel motors and the characteristics of low speed as well as high torque for in-wheel motors, regenerative braking method for in-wheel motors has been presented. All braking torque for vehicle deceleration is output by in-wheel motors under Medium-intensity braking condition for the sake of recovering the maximum braking energy. The vehicle dynamics model that includes the hydraulic braking system and in-wheel motors driving system has been built by AMESim software. Simulation has been carried out for vehicle driving conditions by NEDC cycle and FTP75 cycle. The result shows that the recovery rate of braking energy is increased dramatically by in-wheel motor braking method. The energy efficiency of electric vehicle has been improved more than 30%. It is significant for electric vehicles to increase driving range and reduce costs.
