According to the automobile central control cooperative safety control system provided by the invention, the auxiliary processor is arranged in the central control mainboard system, can be used as an auxiliary computing platform when the central control system is not in a crash state, and is used for sharing and processing task commands. When the system crashes, the central control processor is used as a backup processor to take over vehicle control, so that the consumption of computing resources of the central control processor is reduced, the crashing probability is reduced, and meanwhile, the central control processor can take over and control the vehicle to ensure the safety of the vehicle during crashing; data such as an application program, a currently executed command, a previous command of the currently executed command, current vehicle setting and the like when the vehicle fails are obtained, the fault type and reason are analyzed, whether the command is an easy-to-fail command or not is judged conveniently, resource consumption is calculated when the command is executed, and task commands are distributed in a more accurate mode; the computing resource usage amount of the central control processor is judged through the resource manager, the computing resources of the central control processor are controlled in time, and the probability of crash of the central control processor is further reduced. In this way, the safety of the vehicle central control system is further improved.
本发明提供一种汽车中控协同安全控制系统,在中控主板系统中设置了辅助处理器,可以起到在中控系统未死机状态时作为辅助计算平台使用,用于分担处理任务命令。在系统死机时,作为备份处理器接管车辆控制,既缩减了中控处理器的计算资源的消耗,降低了死机概率,同时在死机时又能接管控制车辆确保了车辆安全;通过获取车辆故障时的应用程序、当前执行的命令、当前执行命令的上一个命令、当前车辆设置等数据,分析故障类型及原因,便于判断命令是否为易故障命令、命令执行时计算资源消耗量,以更精确的方式分配任务命令;通过资源管理器判断中控处理器的计算资源使用量,及时控制中控处理器的计算资源,进一步降低中控处理器死机的概率。通过以上方式进一步提高了车辆中控系统的安全性。
