The wheel looseness monitoring system comprises a pressure detection module 20 and an alarm module 30; the pressure detection module 20 is arranged at the joint of the hub 10 and the hub bracket, and is used for detecting the pressure applied by the bolt 120 to the inner wall surface of the mounting hole 110 and generating a pressure value; the signal output end of the pressure detection module 20 is in communication connection with the whole vehicle controller 40 of the automobile, and transmits a pressure value to the whole vehicle controller 40; the alarm module 30 is in communication connection with a signal output end of the vehicle controller 40. The vehicle controller 40 compares the received pressure value with a preset threshold range, and if the pressure value exceeds the threshold range, the vehicle controller 40 controls the alarm module 30 to alarm.
In the use process, the pressure detection module 20 can detect the pressure between the mounting bolt 120 and the nut of the hub 10 of the automobile, and transmit the detected value to the whole vehicle controller 40 in real time, when the whole vehicle controller 40 judges that the pressure value is in the threshold range, if the pressure value is in the threshold range, the whole vehicle controller 40 does not control the alarm module 30 to alarm. If the vehicle controller 40 determines that the pressure value is not within the threshold range, in this case,
when the pressure value is too large, the hub 10 fixing bolts 120 may be too tight, so that there may be a risk of crushing the hub 10 bolts 120;
when the pressure value is too small, it may be that the hub 10 fixing bolts 120 are loosened, so that there may be a risk of tire falling off; if the automobile is in a running state, potential safety hazards exist; if the automobile is in a stop state, the hidden danger of tire theft exists;
