The invention discloses a low-power-consumption circuit, a vehicle-mounted communication circuit and a vehicle, the circuit comprises an MCU controller, a communication module and a CAN chip, the MCU controller is in communication connection with the communication module and the CAN chip, and when the low-power-consumption circuit enters a first power consumption mode, the CAN chip is in communication connection with the communication module and the CAN chip; the MCU controller, the communication module and the CAN chip are all in a low-power-consumption working state; when the low power consumption circuit enters a second power consumption mode, the MCU controller controls the communication module to be closed and controls the CAN chip to enter a sleep mode and then enters the sleep mode; and when the low-power-consumption circuit enters a third power consumption mode, the MCU controller controls the communication module to be closed and controls the CAN chip to be powered off after being closed. According to the invention, low power consumption in multiple states is realized.

    本申请公开了一种低功耗电路、车载通信电路及车辆,所述电路包括:MCU控制器、通信模组以及CAN芯片,所述MCU控制器分别与所述通信模组、所述CAN芯片通信连接,当所述低功耗电路进入第一功耗模式的情况下,所述MCU控制器、所述通信模组以及所述CAN芯片均处于低功耗工作状态;当所述低功耗电路进入第二功耗模式的情况下,所述MCU控制器控制所述通信模组关闭且控制所述CAN芯片进入sleep模式后自身进入sleep模式;当所述低功耗电路进入第三功耗模式的情况下,所述MCU控制器控制所述通信模组关闭且控制所述CAN芯片关闭后自身断电。通过本申请实现多状态下的低功耗。
