摘　　要：随着汽车电子技术的飞速发展,汽车已经逐渐进入智能化时代。为实现更多的控制功能,车内装载的电子控制单元越来越多,电子控制单元的控制功能也越来越复杂。针对这种现象,有必要对ECU内软件的运行逻辑进行监控,防止软件的运行逻辑出现错误。文章在AUTOSAR架构的基础上,研究了AUTOSAR操作系统内核的关键功能特性,并提出了一种追踪与记录内核中关键功能运行动态的方案。With the rapid development of automobile electronic technology,automobile has gradually entered the era of intelligence.In order to achieve more control functions,more and more electronic control units are loaded in the vehicle,and the control functions of electronic control units are more and more complex.In view of the increasing complexity of the functions of the electronic control unit on the vehicle,it is necessary to monitor the logic of the running software in the ECU to prevent logic errors of the software.On the basis of AUTOSAR architecture,the key functional characteristics of the kernel of AUTOSAR operating system are studied,and on this basis,a scheme to track and record the dynamic operation of key functions in the kernel is proposed.
