Research on the control strategy of distributed electric vehicle based on xpc test platform

In this paper, the distributed hybrid electric vehicle is taken as the research object. A drive control strategy is proposed based on the optimal working curve control strategy of the engine, and taking full consideration of the battery SOC working range and boundary speed threshold. The strategy model was generated xPC Target executable program by MATLAB/RTW toolbox and it was downloaded to the target machine to be run in real-time. The vehicle controller access the xPC real-time simulation testing system, which have simulation analysis on the condition of 0-32km/h acceleration. The test results demonstrate that the hardware in the loop simulation of xPC structure is feasible, and the real-time simulation testing system is reliable, meanwhile the rationality of the driving control strategy on this platform is verified.
