After the automobile wheel 2 is punctured, the automobile danger guarantee device is triggered, and the automobile accident can be effectively prevented.
When the vehicle wheel 2 is not moved to the flexible anti-skid member 51, if the lubricating device 8 releases the lubricating oil to the vehicle wheel 2, the friction between the vehicle wheel 2 and the ground is reduced, and the vehicle wheel is easy to slip. To avoid this, in step S3, before the lubricating device 8 works, the pulling force value of the flexible anti-skid member 51 on the vehicle body 1 and the rotating speed value of the vehicle wheel 2 need to be obtained, and only when the pulling force value is not less than the preset pulling force value and the rotating speed value of the vehicle wheel 2 is greater than the preset rotating speed, the electric nozzle is controlled to be turned on to release the lubricating oil toward the vehicle wheel 2, so as to reduce the friction between the vehicle wheel 2 and the flexible anti-skid member 51. Wherein, the pulling force value of the flexible anti-skid piece 51 to the automobile body 1 is obtained by a pressure sensor between the flexible anti-skid piece 51 and the connecting rod 6, and the rotating speed value of the automobile wheel 2 is obtained by a rotating speed sensor at the automobile wheel 2.
