Design of Vehicle Control Unit Based on DSP for a Parallel HEV

This paper presents a DSP based vehicle control unit (VCU) for hybrid electric vehicle (HEV). Digital signal processor (DSP) based real time controller plays a key role in HEV system operation. It provides an efficient platform to run complex optimization algorithms for energy management strategy. First, the hardware design of VCU is introduced in detail. Then software design of VCU and C code automatic generation technical based on RTW are discussed. A flexible and configurable method is described to automatically deploy the Simulink-model into the VCU. Experimental results have demonstrated the reliability of hardware design and flexibility of software design of the proposed VCU.
