The invention provides a sampling circuit, a sampling system and a vehicle body, and relates to the technical field of vehicle control. The sampling circuit comprises a voltage division circuit, a first filter circuit, a controller and at least two switching circuits. Each switch circuit in the at least two switch circuits comprises a controllable switch; the first end of each switch circuit in the at least two switch circuits is used for connecting a sensor, and the second end of each switch circuit in the at least two switch circuits is used for connecting the first end of the voltage division circuit; the first end of the voltage division circuit is also connected with a first power supply, the second end of the voltage division circuit is grounded, and the output end of the voltage division circuit is connected with the input end of the controller; the first filter circuit is used for filtering the voltage division circuit; the controller is used for controlling the controllable switches so that the controllable switches can be turned on according to a preset sequence. According to the scheme provided by the invention, the number of interfaces occupied for connecting the input signal of the sensor is reduced, the circuit layout is simplified, the hardware cost is reduced, and the reliability of the circuit is improved.
