提供了具有非对称系统架构的车辆系统控制器和操作车辆系统控制器的方法。车辆系统控制器包括与车辆系统通信的主控制器和辅助控制器。两种控制器中的每一种包括含有软件应用程序的存储器单元和用于执行软件以生成用于车辆系统的命令的处理器。辅助控制器的存储器单元仅包含主控制器的存储单元中包含的全部软件应用程序的一个子集。该软件应用程序的子集仅用于操作车辆系统的预先识别的功能。车辆系统被配置为将来自主控制器的命令设为默认，但是如果主控制器变为故障无反应，则在预定时间长度内切换至来自辅助控制器的命令。 A vehicle system controller having an asymmetric system architecture and a method of operating the vehicle system controller is provided. The vehicle system controller includes a primary controller and a secondary controller in communications with the vehicle systems. Each of the controllers include a memory unit containing software application and a processor for executing the software to generate commands for the vehicle systems. The memory unit of the secondary controller contains only a subset of the total software applications contained in the memory unit of the primary controller. The subset of software applications is only for the operation of pre-identified features of the vehicle systems. The vehicle systems are configured to default to commands from the primar
