基于DSP的混合动力车辆综合控制系统设计

混合动力车辆已经成为汽车技术研究的热点,而总线通讯技术和分布式控制网络在汽车电子领域应用日益广泛。为实现混合动力车辆的能量管理和运动控制,设计开发了基于TI公司TMS320LF2407型号DSP的综合控制系统。在系统拓扑结构设计的基础上,实现了DSP片外存储单元的扩展,实现了通过CAN总线与整车分布式控制网络的通讯。实车实验表明,该综合控制系统能够实现对混合动力车辆实时性的驱动控制,硬件系统工作可靠,软件系统具有移植性;CAN总线通讯可以满足车辆实时性控制的要求。

Integrated Powertrain Controller Design for Hybrid Electric Vehicle Based on TMS320LF2407

Hybrid electric vehicle has become hot-spot in automotive engineering, and bus communication and distributed control network are widely used in automotive electronics. To realize energy management and kinetic control of HEV, integrated power-train controller is designed based on DSP TMS320LF2407 of TI. Accomplishing system topological structure design, off-chip memory space was expanded, CAN bus and distributed control network was realized. The results of vehicle experiment suggest that, real-time driving control of HEV can be realized by integrated power-train controller. Hardware system works reliably and software system trans- plantation is good.
