The above-mentioned operating system may specifically include: an embedded real-time operating system, a Linux operating system, and a Windows operating system. system, and Android operating system and other operating systems; wherein, the security levels of the operating systems running in the above-mentioned processors are different, and specifically may include: the operating system of the first security level and the operating system of the second security level, the first security level The security level of the operating system is higher than the security level of the operating system of the second security level; the security level of the above-mentioned operating system is a kind of identification of the security of the above-mentioned operating system, and the security of the operating system with a higher security level is more secure. High, that is, an operating system with a high security level is more stable and less likely to crash or be attacked, that is, the security of the operating system with the first security level is higher than that of the operating system with the second security level .
本发明实施例中，上述车载系统中运行的任务具体可以包括：车身控制任务、车内信息娱乐任务等任务，其中，上述车身控制任务为对车身的控制任务，例如：车门开关任务、车窗开关任务、车启动/熄灭任务、车后备箱的开关任务、空调任务、手刹任务等任务；上述车内信息娱乐任务为车内除车身控制任务之外的任务，例如：GPS(全球定位系统，GlobalPositioning System)导航任务、娱乐任务(游戏、音响、视频等任务)、支付任务等任务。In the embodiment of the present invention, the above-mentioned tasks running in the on-board system may specifically include: vehicle body control tasks, in-vehicle infotainment tasks and other tasks, wherein the above-mentioned vehicle body control tasks are control tasks on the vehicle body, such as: door switch tasks, vehicle window tasks, etc. Switching tasks, car start/stop tasks, car trunk switching tasks, air conditioning tasks, handbrake tasks and other tasks; the above-mentioned in-car infotainment tasks are tasks other than body control tasks in the car, for example: GPS (Global Positioning System, GlobalPositioning System) navigation tasks, entertainment tasks (games, audio, video, etc.), payment tasks and other tasks.
本发明实施例中，上述车载系统中运行的任务的安全级别也不同，上述任务的安全级别是人们对于上述任务的安全性重视程度的一种表示，对于车载系统而言，对于会对车身及人身安全造成威胁的任务(例如：车身控制任务)，往往需要绝对的安全性，则这些任务的安全级别则是靠前的，可以为第一安全等级的任务，其需要运行在安全级别较高的操作系统中；而对于对用户的用户体验造成影响的车内信息娱乐，可以为第二安全等级的任务，其可以运行于安全级别低于车身控制任务所在的操作系统中。In the embodiment of the present invention, the security levels of the tasks running in the above-mentioned vehicle systems are also different. The security levels of the above-mentioned tasks are an expression of the degree of attention people attach to the safety of the above-mentioned tasks.

可以理解，上述车载系统中包括两个或者三个处理器中仅作为本发明实施例中上述车载系统中的处理器中的数量的示例，而不理解为是对本发明实施例上述车载系统中的处理器中的数量的一种限定，实际上，上述车载系统中还可以包括三个以上的处理器，本发明实施例在此不对上述车载系统中的处理器的数量加以限定。It can be understood that the two or three processors included in the above-mentioned vehicle-mounted system are only used as an example of the number of processors in the above-mentioned vehicle-mounted system in the embodiment of the present invention, and should not be understood as a reference to the number of processors in the above-mentioned vehicle-mounted system in the embodiment of the present invention. A limitation on the number of processors. In fact, the vehicle-mounted system may include more than three processors. The embodiment of the present invention does not limit the number of processors in the vehicle-mounted system.
在本发明的一种应用实例中，车载系统中包括有两个处理器：第一处理器及第二处理器，其分别运行第一安全级别的第一操作系统和第二安全级别的第二操作系统，且上述第一操作系统的安全级别大于上述第二操作系统的安全级别，则上述第一操作系统用于运行车身控制任务，上述第二操作系统用于运行车内信息娱乐任务，由于车内信息任务较车身控制任务而言更易出现问题，且车身控制任务对车身及人身安全的威胁更大，用户对车身控制任务的安全性更为重视，将上述车身控制任务与车内信息娱乐任务分别运行在两个处理器的两个操作系统中，这样一来，第一，由于第一操作系统的安全级别高于第二操作系统的安全级别，因此可以从操作系统的层面保证上述车身控制任务的安全性；第二，可以保证上述车身控制任务不受车内信息娱乐任务的影响，也即当车内信息娱乐任务出现问题时，由于车身控制任务与其不在同一处理器中的操作系统中运行，则车内信息娱乐任务的问题不会对车身控制任务造成影响，可以保证车身及人身安全，例如：当第二操作系统中运行的某一联网的任务，如视频任务携带病毒，进而导致上述第二操作系统死机时，车身控制任务则不会受到影响，仍然可以正常运行；当第二处理器出现问题(例如：高温烧坏，元器件脱落等问题)时，由于车身控制任务在在第一处理器中的第一操作系统中运行，因此第二处理器的损坏不会对上述车身控制任务造成影响，因此，可以保证车身及人身安全。In an application example of the present invention, the vehicle-mounted system includes two processors: a first processor and a second processor, which run the first operating system of the first security level and the second operating system of the second security level respectively. operating system, and the security level of the first operating system is greater than the security level of the second operating system, the first operating system is used to run the vehicle body control task, and the second operating system is used to run the infotainment task in the vehicle, because In-vehicle information tasks are more prone to problems than vehicle body control tasks, and body control tasks pose a greater threat to vehicle body and personal safety.

In the embodiment of the present invention, the above-mentioned in-vehicle infotainment task Can be divided into three parts of tasks, the first part of tasks (for example: tasks such as video tasks, audio tasks, game tasks) can run in the second operating system 1021, and the second part of tasks (for example: payment tasks) can run on the above-mentioned third part of the task. In the operating system 1031, the third part of the task (for example: GPS task) can run in the fourth operating system 1041; The running tasks will affect the tasks in the above-mentioned first operating system 1011, the third operating system 1021 and the fourth operating system 1041; The operating system is independent in terms of resources such as physical memory, and there will be no resource preemption; 103 and the fourth processor 104, that is, the tasks running in the first operating system 1011 in the first processor 101, the tasks running in the third operating system 1031 in the third processor 103, the fourth processor The tasks running in the fourth operating system 1041 in 104 will not be affected by the second processor, and can still run normally.
本发明实施例中，上述不同的处理器中运行不同的操作系统，且不同的操作系统中运行不同的任务，当上述处理器中的操作系统中没有任务执行时，该处理器可以不用启动，也即本发明实施例中仅启动有任务执行的处理器即可，由于上述DSP处理器、MPU处理器、及MCU处理器的待机功耗均较小，因此，上述车载系统的功耗较低，例如：车的防盗任务运行于MCU处理器的操作系统中，当用户离开车后，其他任务均关闭，但是防盗任务仍然需要开启着，而由于防盗任务与其他任务运行与不同的处理器中，其他处理器可以处于休眠状态，而只开启上述MCU处理器，由于MCU处理器是功耗较低的处理器，因此本发明实施例提供的车载系统可以带来较小的功耗。In the embodiment of the present invention, different operating systems are run in the above-mentioned different processors, and different tasks are run in different operating systems.

When the user leaves the car, other tasks are closed, but the anti-theft task still needs to be turned on, and because the anti-theft task and other tasks run in different processors , other processors may be in a dormant state, and only the above-mentioned MCU processor is turned on. Since the MCU processor is a processor with low power consumption, the vehicle-mounted system provided by the embodiment of the present invention can bring relatively low power consumption.
