基于Targetlink自动代码生成的混合动力汽车巡航控制策略

Cruise Control Strategy of HEV Based on Automatic Code Generation of Targetllink

为了缩短混合动力汽车巡航控制策略的开发周期从而达到有效降低开发成本的目的,使用MATLAB/Simulink和d SPACE/Targetlink工具采用基于模型的设计,根据混合动力汽车动力系统特点,设计了混合动力系统与巡航控制相结合的协同控制算法,完成了混合动力巡航控制策略建模和自动代码生成,并把生成的高效C代码下载到产品级控制器中,实现了混合动力汽车不同工况下的智能巡航控制。试验结果表明,车辆各工况下的巡航车速稳定控制在目标需求范围内,达到了设计要求;通过采用自动代码生成技术大大缩短了开发周期,提高了系统开发效率。

For the sake of reducing development costs effectively by shortening lead time of HEV control system, cooperative control algorithms between HEV and cruise control were designed by use of model-based approach, models of cruise control strategy for HEV and auto-code generation were finished with MATLAB/Simulink and d SPACE/Targetlink, the efficient C code for HEV Cruse system were writed into ECUs. The test results showed that cruise speed was steadily controlled within certain range, meeting the design requirements; the results indicated that the technology of auto-code generation was effective in cutting down iteration and raising efficiency of system development.
