The invention provides a starting circuit and starting method of a communication module, a vehicle-mounted wireless terminal and a vehicle, the starting circuit of the communication module is applied to the vehicle-mounted wireless terminal, the starting circuit comprises a power supply chip, the output end of the power supply chip is connected with the communication module, and the power supply chip is used for providing a voltage signal for the communication module; the control chip comprises a monitoring end and a control end, and the monitoring end is connected with the power supply chip and used for monitoring whether the voltage signal output by the output end of the power supply chip meets a preset condition or not; and the control end is connected with the communication module and is used for controlling the communication module to start under the condition that the monitoring end monitors that the voltage signal meets the preset condition. Whether the voltage signal output by the output end of the power supply chip meets the preset condition or not is monitored through the monitoring end of the control chip, the communication module is controlled to be started through the control end, the starting stability of the communication module is improved, and the probability of starting failure caused by unstable power supply voltage is reduced.
本申请提供一种通信模组的启动电路、启动方法、车载无线终端及车辆,其中,通信模组的启动电路应用于车载无线终端,启动电路包括:供电芯片,供电芯片的输出端与通信模组连接,用于为通信模组提供电压信号;控制芯片,控制芯片包括监测端和控制端,监测端与供电芯片连接,并用以监测供电芯片输出端输出的电压信号是否满足预设条件;控制端与通信模组连接,并用以在监测端监测到电压信号满足预设条件的情况下控制通信模组启动。本申请通过控制芯片的监测端对供电芯片的输出端输出的电压信号是否满足预设条件进行监测,并通过控制端控制通信模组启动,提高了通信模组的启动稳定性,降低了由于供电电压不稳导致的启动失败的概率。
