Transient optimization of drive control strategy for pure electric passenger car

Use a pure electric passenger car as a research object, design drive control strategy in three modes for different driving conditions and provide motor target torque. To solve the affect of the change of SOC in actual motor output torque, use a penalty function to instantaneously optimize the target torque. Vehicle controller can get the target torque and the correct torque at different motor speed, different accelerator pedal opening and different SOC in look-up way. Create vehicle models and do simulations, then do road tests for the pure electric passenger car. It can be proved that the drive control strategy is practical and effective.
