The Upgradable Car: Safely Extensible Automotive Systems and Software

本研究的目的是创建一个安全可扩展的汽车系统和软件架构（SEASAR）以及相关的开发和质量保证方法，通过独立供应商生产的智能应用程序和设备实现汽车的制造后可升级性。考虑的升级范围从车身领域的个性化和信息娱乐到增加新的安全增强驾驶员辅助功能。实现这种升级的主要挑战是确保安装步骤和升级后的汽车的可用性、可靠性、安全性和安全性。SEASAR将使安装变得简单和可靠，在安装时使用具有资源预留和诊断功能的安装程序，并通过运行时监控和修复提高可靠性和安全性。相关的开发方法侧重于特征交互的早期建模、分析和解决，以及在添加新应用程序和设备时避免认知过载的人机界面的设计。质量保证方法包括使用基于模型的技术进行验证和确认，以提高效率并降低成本，以及在启用seasar的车辆中验证新软件和设备的使用方法。该技术将通过在一辆扩展了SEASAR的测试车上增加个性化的内部灯、酒精联锁系统和三个驾驶员辅助功能来展示。可升级汽车的愿景为加拿大汽车和信息通信技术行业提供了巨大的机会，因为SEASAR将支持汽车应用和设备的生态系统，为加拿大汽车零部件供应商和信息通信技术公司提供比现在更广泛的汽车供应链和售后市场。该项目还将培训28名高质量的人员，在工程上使用、安全、可靠和可靠的嵌入式软件，并在实际测试车辆上为他们提供汽车系统的实践经验。

The objective of this research is to create a Safely Extensible Automotive Systems and Software Architecture (SEASAR) and associated development and quality-assurance methods to enable post-manufacturing upgradability of automobiles through smart apps and devices produced by independent suppliers. The considered upgrades range from personalization in the car-body domain and infotainment to adding new safety-enhancing driver-assistance features. The main challenge to enabling such upgrades is ensuring the usability, reliability, safety, and security of both the installation step and the upgraded automobile. SEASAR will make installation simple and reliable using an installer with resource reservation and diagnostics at installation time and enhance reliability and safety through runtime monitoring and repair. The associated development method focuses on early modeling, analysis, and resolution of feature interactions and on designing human-machine interfaces that avoid cognitive overload when new applications and devices are added. The quality assurance methods include verification and validation using model-based techniques to improve effectiveness and reduce cost, and a method to certify the use of new software and devices in a SEASAR-enabled vehicle. The technology will be demonstrated by adding personalization of interior lights, an alcohol interlock, and three driver-assistance functions to a test vehicle extended with SEASAR. The Upgradable Car vision offers tremendous opportunities to Canadian automotive and ICT industry, in that SEASAR will support an ecosystem of automotive apps and devices, providing Canadian automotive parts suppliers and ICT companies with wider access to the automotive supply chain and aftermarket than they have today. The project will also train 28 of highly-qualified personnel in engineering usable, safe, reliable, and secure embedded software and give them hands-on experience in automotive systems on an actual test vehicle.
