使用基于模型和自动代码生成技术研究整车控制器(VCU)的控制策略和算法及其代码化,结合软件开发平台技术,按照V+v开发模型对双轴并联混合动力客车的VCU进行了开发。分析讨论了V+v模型中每个节点的关键技术,全新开发了VCU的控制策略和算法,基于相同模型利用多种仿真模式对自动生成的产品质量代码进行了测试。以符合OSEK标准的OS为核心构建了适用于32位微控制器的软件开发平台。最后,在半车试验台和整车上对VCU进行了功能测试和验证,结果表明采用V+v模型开发VCU可以提高开发质量、缩短开发周期、降低开发成本。
The control strategy and algorithm as well as its coding of the vehicle control unit(VCU) were studied using the model-based and the autocode technique.AVCU was developed for a 2-axes parallel hybrid bus based on the V+v model using the software development platform technology.The key issues of each node in the V+v model were analyzed and discussed,and a brand-new control strategy and algorithm were developed for the VCU,and the automatically generated product quality code was tested using different simulat...
