The invention relates to a signal acquisition circuit, a control method, a vehicle control unit and a vehicle, the signal acquisition circuit comprises a switch module, a pull-up resistor and a pull-down resistor, the control end of the switch module serves as the control end of the signal acquisition circuit and is used for receiving a control signal sent by a control chip, The control module is used for controlling the first end and the third end of the switch module to be connected and controlling the second end and the fourth end of the switch module to be disconnected when the control signal is a first level signal. The switch module is used for controlling the first end and the third end of the switch module to be disconnected and controlling the second end and the fourth end of the switch module to be connected when the control signal is a second level signal. According to the control signal sent by the control chip, the pull-up resistor and the pull-down resistor of the signal acquisition circuit can be flexibly configured, the hardware version of the signal acquisition circuit is reduced, and the production cost is low.

    本公开涉及一种信号采集电路、控制方法、整车控制器和车辆,该信号采集电路包括:开关模块、上拉电阻和下拉电阻,开关模块的控制端作为信号采集电路的控制端,开关模块的控制端用于接收控制芯片发送的控制信号,开关模块,用于在控制信号为第一电平信号时,控制开关模块的第一端与第三端连接,并控制开关模块的第二端和第四端断开,开关模块,用于在控制信号为第二电平信号时,控制开关模块的第一端与第三端断开,并控制开关模块的第二端和第四端连接。本公开根据控制芯片发送的控制信号,能够灵活地对信号采集电路的上拉电阻和下拉电阻进行配置,减少了信号采集电路的硬件版本,生产成本低。
