The invention discloses a vehicle machine device with a mode switching function and a control method, the vehicle machine device comprises a TYPE-A female port, a processing module, a detection circuit, a communication circuit and a power supply circuit, the processing module is connected with a power supply pin of the TYPE-A female port through the detection circuit and is connected with a data pin of the TYPE-A female port through the communication circuit, the power circuit is connected with the processing module and the power supply pin, and the processing module is used for judging whether the power supply pin has voltage or not through the detection circuit under a preset condition; if yes, the communication mode is switched to the HOST mode, and if not, the communication mode is switched to the OTG mode; the processing module is further used for controlling the power circuit to provide voltage for the power supply pin in the OTG mode. The method is convenient for maintenance personnel to debug and maintain, so that the vehicle machine system is more convenient to use, and convenience is provided for capturing the date of the whole vehicle, analyzing the BUG and possibly existing hidden dangers.

    本发明公开了一种具有模式切换功能的车机装置及控制方法,所述车机装置包括一TYPE‑A母口,车机装置还包括一处理模块、一检测电路、一通信电路以及一电源电路,处理模块通过检测电路连接TYPE‑A母口的电源供应引脚并通过通信电路连接TYPE‑A母口的数据引脚,电源电路连接所述处理模块以及电源供应引脚,处理模块用于通过检测电路判断预设条件下电源供应引脚是否存在电压,若是则将通信模式切换至HOST模式,若否则将通信模式切换至OTG模式;处理模块还用于在OTG模式下控制电源电路向电源供应引脚提供电压。本发明方便维修人员调试维修,使得车机系统使用起来更为方便,为抓取整车日期、分析BUG和可能存在隐患提供便利。
