The invention discloses a vehicle-mounted system and a control method of the vehicle-mounted system. The system comprises a central computing unit, a storage unit, a peripheral unit, a trusted computing unit, an accelerated computing unit and a management unit, and the management unit is used for controlling the central computing unit, the storage unit, the trusted computing unit, the accelerated computing unit and the peripheral unit. The method comprises the following steps: a management unit receives a first instruction when the vehicle-mounted system is in a normal working mode, and performs first control on each unit in response to the first instruction; the management unit receives a second instruction that the vehicle-mounted system is in a low-power-consumption mode, and performs second control on each unit in response to the second instruction; and under the condition that the management unit detects that the duration of the vehicle-mounted system in the low-power-consumption mode exceeds the first preset duration, performing third control on each unit. The technical problem that the power consumption of the vehicle-mounted system is too large due to the fact that all units of the vehicle-mounted system based on the X86 architecture cannot be managed in a centralized mode is solved.
本申请公开了一种车载系统及车载系统的控制方法。其中,该系统包括:中央计算单元、存储单元、外设单元、可信计算单元、加速计算单元以及管理单元,管理单元,用于控制中央计算单元、存储单元、可信计算单元、加速计算单元和外设单元。该方法包括:管理单元接收车载系统处于正常工作模式下的第一指令,响应于第一指令,对各单元进行第一控制;管理单元接收车载系统处于低功耗模式下的第二指令,响应于第二指令,对各单元进行第二控制;在管理单元检测到车载系统处于低功耗模式的时长超过第一预设时长的情况下,对各单元进行第三控制。本申请解决了由于无法对基于X86架构的车载系统的各单元进行集中管理造成的车载系统的功耗过大的技术问题。
