The invention belongs to the field of automobile energy conservation, and particularly discloses a low-power-consumption control method and system for a vehicle-mounted information entertainment terminal, a medium and equipment, and the method comprises the steps that the gear state of a vehicle-mounted power source is collected; when the gear is a closed gear, acquiring the running state of the upgrading program, and when a preset dormancy condition is met, sending a dormancy instruction to the system-on-chip; obtaining the working state of the system-on-chip, comparing the working state with a preset power-off condition, and implementing a sleep wake-up strategy according to a comparison result, including adjusting the power-on and power-off states of the peripheral power supply and the system-on-chip power supply, enabling the micro-control unit to enter a low-power-consumption mode, and when the power supply gear state is detected to meet the preset wake-up condition in the low-power-consumption mode, executing the sleep wake-up strategy. And the micro-control unit and the system-on-chip are awakened. The micro-control unit and the system-on-chip are awakened in a dormancy mode based on the upgrading behavior of the upgrading program, the problem that after the micro-control unit fails to be flashed, the vehicle-mounted information entertainment terminal does not sleep, and consequently the whole vehicle is lack of electricity is solved, and the vehicle is low in energy consumption and more energy-saving.
本发明属于汽车节能领域,具体公开车载信息娱乐终端的低功耗控制方法、系统、介质及设备,该方法包括采集车载电源的档位状态;为关闭档位时,获取升级程序的运行状态,满足预设休眠条件时,对系统级芯片发送休眠指令;获取系统级芯片的工作状态并与预设断电条件比较,根据比较结果实施休眠唤醒策略,包括调整外设电源、系统级芯片电源的上下电状态,使微控制单元进入低功耗模式,以及在低功耗模式下,检测到电源档位状态满足预设唤醒条件时,对微控制单元和系统级芯片进行唤醒。本发明基于升级程序的升级行为对微控制单元和系统级芯片进行休眠唤醒,解决微控制单元刷写失败后,车载信息娱乐终端不休眠导致整车亏电的问题,车辆能耗低、更节能。
