The present invention discloses a power-saving mode control method and device applied to a vehicle-borne terminal. The method and the device are applied to the MCU arranged in the vehicle-borne terminal. Through the method and the device, after the MCU receives flameout information, the time of receiving the flameout information is set as a first time, the timing is started from the first time, if the MCU always does not receive the effective information transmitted by a CAN bus in the preset time period from the first time, each component in the vehicle-borne terminal is controlled to enter into a power-saving mode, thus the power is saved, and the problem of large power consumption by the vehicle-borne terminal in the prior art is solved. 本申请公开种应用于车载终端的节电模式控制方法及装置，该方法及装置应用于设置在车载终端中的MCU。通过本申请，MCU在接收到熄火信息后，设定接收到熄火信息的时间为第时间，并从所述第时间开始计时，若从所述第时间开始的预设时间段内，所述MCU始终未接收到CAN总线传输的有效信息，则控制所述车载终端中的各个元器件进入节电模式，从而节省电量，解决了现有技术中存在的，车载终端会耗费大量电能的问题。
