摘要:
针对电动汽车电驱动系统中存在的关键技术问题，设计了基于CAN（controller area network）总线的电动汽车电驱动系统。系统由CAN通信模块和电机控制模块组成。CAN通信模块采用新型CAN总线收发器TJA1040和独立CAN控制器，并采用各种抗干扰措施以保证CAN通信的稳定性；控制模块利用模糊矢量控制方案——直接速度控制（direct speed control，DSC）策略，实现电驱动系统高鲁棒性控制。系统兼容性强，可以作为单独模块连接到电动汽车的主干网络上，还可以通过CAN总线对其进行
Abstract:
To solve the key problems of the electric drive system, a controller area network(CAN)based electric drive system for electric vehicles was designed. The system was composed of two parts: a CAN communication module and a motor control module. The newest transceiver (TJA1040) and a standalone CAN controller were used during the design of the CAN communication module, and antijamming measures were employed to guarantee communication stability. The fuzzyvector control method and direct speed control were applied to realize highly robust control functions. This system has high compatibility. It can be installed in electric vehicles as an independent module and be extended through CAN Bus.
