The embodiment of the invention relates to the technical field of in-vehicle infotainment detection, in particular to a voltage detection circuit and an in-vehicle infotainment system. According to the embodiment of the invention, the first detection circuit and the second detection circuit are arranged to detect the voltage of the first power supply, and the electric signal of the reset end of the system controller is controlled according to the detection result. Through the scheme of the invention, when the first detection circuit or the second detection circuit fails, the system controller can still be reset through the other detection circuit, so that the problems of failure of single-point detection, normal reset of the system and influence on calculation of single-point fault measurement are solved, and the system has higher reliability and safety.
本发明实施例涉及车机检测技术领域,具体涉及电压检测电路及车机系统。本发明实施例通过设置第一检测电路、第二检测电路分别对第一电源进行电压检测,并根据检测结果对系统控制器的复位端的电信号进行控制。通过本发明的方案,可以在第一检测电路或第二检测电路失效时,仍可以通过另一检测电路对系统控制器进行复位,解决了单点检测失效,系统正常复位以及影响单点故障度量的计算的问题,使系统具有更高的可靠性和安全性。
