Overview Study of Multi-Dynamic Coupling Drive System on EV

Abstract:

The multi-dynamic coupling drive system can coordinate the operating characteristics of all power sources, optimize the total efficiency and driving characteristic of the drive system, and hence improve the performance of electric vehicles. Therefore, it has greater energy saving potential and better prospects. Under the premise of meeting the needs of electric vehicle performance, how to synthesis and decompose the output power of the different power sources reasonablely and efficiently is the core problem. There are a number of driving modes existing in the the multi-dynamic coupling drive electric vehicles. The coordination control of the torque of related power sources during the transition among different modes is essential to vehicle’s power and ride comfort performance. It is meaningful to improve the system efficiency and drivability performance by control strategy, while ensuring the capability of energy saving and emission reduction.
