10. A method for using a vehicle minimum turning radius measuring device according to claims 1-9, characterized in that: comprises the following steps: S1. Runway laying and switching: First, evenly lay sediment and water on the surface of the blanket board (1022) until the blanket board (1022) stores the water and sediment inside. Then, according to the required road simulation conditions, when testing on an icy road surface is needed, power on and start the cooler (1012). The cooler (1012) will cool the heat conduction plate (1013), and the heat conduction plate (1013) will cool the blanket board (1022) until the sediment and water on the blanket board (1022) freeze. After that, the tester drives the vehicle into the support base (1011) from the access ramp panel (1051) and the external access (1033). Then, the tester drives the vehicle around the blanket board (1022) for a turning test. When testing on a muddy road is needed, turn off the cooler (1012) and wait for the ice on the blanket board (1022) to melt. S2. Measurement of the minimum turning radius of the vehicle: First, when the vehicle is turning, the user can control the control panel (2013) to control the observation camera (2023). The observation camera (2023) will collect images of the vehicle's turning situation and transmit the image information to the processor base (2012). Then, the processor base (2012) will analyze the images to obtain the information on the minimum turning radius of the vehicle during turning, and the user can record the information.
