The invention relates to the technical field of vehicles, particularly provides a vehicle high-voltage loop power-on and power-off control method and device, a medium and a vehicle, and aims to solve the technical problem that an existing method for judging whether a high-voltage component connector is exposed or not affects the electromagnetic compatibility of the vehicle. In order to achieve the purpose, the high-voltage loop comprises a high-voltage bus and a high-voltage component, a high-voltage connector is connected between the high-voltage bus and the high-voltage component, and the power-on and power-off control method for the high-voltage loop of the vehicle comprises the steps that the actual voltage and the voltage threshold value of the high-voltage component are obtained; judging whether the high-voltage connector is disconnected or not based on the actual voltage and the voltage threshold value; and under the condition that the high-voltage connector is disconnected, the high-voltage loop is controlled to be powered off. In this way, accurate control over the high-voltage loop of the vehicle is achieved, and the electromagnetic compatibility of related high-voltage components or the whole vehicle is improved.
