Prompting method and device for vehicle-mounted cold and warm box, electronic equipment and readable storage medium

The invention relates to the technical field of vehicles, and provides a prompting method and device for a vehicle-mounted cold and warm box, electronic equipment and a readable storage medium. The method comprises the steps that the pressure value of an object in the vehicle-mounted cold and warm box is detected through a pressure sensor arranged at the bottom of the vehicle-mounted cold and warm box; when the box door of the vehicle-mounted cold and warm box is opened, if the first pressure value when the box door of the vehicle-mounted cold and warm box is opened is reduced to be smaller than the first preset value and the duration that the first pressure value is smaller than the first preset value is longer than the first preset duration, it is judged that no article exists in the vehicle-mounted cold and warm box; if the second pressure value is larger than a second preset value when the box door of the vehicle-mounted cold and warm box is closed, and the duration that the second pressure value is large
