The invention discloses a high-voltage interlocking detection circuit and method and a vehicle. The high-voltage interlocking detection circuit comprises a high-voltage loop; the signal source is used for outputting a detection signal; the first end of the sampling resistor is connected with the first end of the signal source, and the second end of the sampling resistor is connected with the high-voltage loop, so that when the detection signal is output, the high-voltage interlocking state of the high-voltage loop is detected through the voltage value of the sampling resistor. By adopting the circuit, the cost of high-voltage interlocking detection can be reduced.
