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.
