新能源汽车VCU诊断软件系统开发

A Developing Method of New Energy vehicle Diagnostic System

近年来,随着新能源汽车技术特别是智能化汽车技术的发展,汽车电子领域发生了重大的变革—汽车电子系统日趋复杂,电控元器件日益增加。汽车电子的变革导致了汽车软件开发平台化及标准流程化占据了更重要地位。对汽车整车控制器(VCU)软件开发,功能安全及诊断模块的开发需要对更多的电子控制单元进行诊断监控,保证车辆的安全与舒适性。基于此,文章对汽车诊断功能软件、平台化的软件开放式架构、功能安全评估手段进行了深入的研究。

In recent years, with the development of new energy vehicle technology, especially intelligent vehicle technology, great changes have taken place in the field of automotive electronics. The reform of automotive electronics has led to the automobile software development platform and process standards occupy a more important position. In order to ensure the safety and comfort of the vehicle, more electronic control units should be used for the development of the software of the vehicle controller, functional safety and diagnostic module. Based on this, this paper makes an in-depth study of the automo -tive diagnostic software, the open architecture of the platform software, and the means of functional safety assessment.
