The invention provides a high-voltage interlocking detection system, a vehicle comprising the high-voltage interlocking detection system and a high-voltage interlocking detection method. The high-voltage interlocking detection system comprises a low-voltage power supply, a high-voltage power supply, a high-voltage power distribution device, a high-voltage load, a voltage detection device and a controller. The low-voltage power supply is used for outputting low-voltage power. The high-voltage power supply is used for outputting high-voltage power. The high-voltage load comprises a high-voltage port electrically connected with the high-voltage power distribution device, and the high-voltage power distribution device is used for providing low-voltage power output by the low-voltage power supply or high-voltage power output by the high-voltage power supply to the high-voltage load. The voltage detection device is used for detecting the voltage of the high-voltage load and outputting a corresponding first electric signal. And the controller is in communication connection with the low-voltage power supply, the high-voltage power supply and the voltage detection device, and is used for controlling the high-voltage power supply not to output high-voltage electricity, controlling the low-voltage power supply to output low-voltage electricity and determining whether the high-voltage port is disconnected according to the first electric signal of the voltage detection device. According to the invention, the detection of the high-voltage interlocking system can be carried out when the system is not electrified by high voltage, and the detection is more timely.
