[0003] The existing tire pressure monitoring system mainly adopts the indirect type and the direct type. Compared with the indirect type, the direct type has many advantages. The control board is used as the upper computer, and then the tire pressure monitoring sensors are set one by one in the four tires, and the effect of monitoring tire pressure data is realized through wireless transmission between the two. Electric energy will not report data in real time, so when the tire pressure sensor fails, the car main control board in the car will not be able to know the current tire pressure sensor failure in a timely and effective manner, especially when the vehicle is stopped and the tire pressure When the sensor is in a dormant state, it is even more impossible to know whether the current tire pressure sensor has failed

[0036] As an improved specific implementation, the step 4 also includes the step of comparing with each other:
[0037] Step 41, calculating the variance of each tire pressure data;
[0038] Step 42, extracting the tire pressure data with the largest variance, and simultaneously extracting the tire pressure sensor corresponding to the tire pressure data;

The invention discloses a fault judgment method for a tire pressure monitoring system, which comprises the following steps of: 1, sending an activation signal into a tire pressure sensor by using maintenance equipment, and activating the tire pressure sensor; step 2, receiving the tire pressure data sent by each tire pressure sensor through the maintenance equipment, and if the tire pressure data is not received, indicating that the tire pressure sensor fails; step 3, after the maintenance equipment receives the tire pressure data; and 4, measuring the tire pressure data of the tire corresponding to the tire pressure sensor through an external method. According to the fault judgment method for the tire pressure monitoring system, whether the tire pressure monitoring system breaks down or not can be effectively detected through the arrangement of the first step, the second step, the third step and the fourth step.
Description
technical field [0001] The invention relates to a judging method, in particular to a tire pressure monitoring system fault judging method. Background technique [0002] The tire pressure monitoring system is an extremely important system on the vehicle at present. By monitoring the tire pressure of the tire, it can effectively understand the current tire pressure status of the car tire and make timely reminders to remind the driver to replenish the tire pressure in time. , to avoid problems caused by insufficient or excessive tire pressure during vehicle driving. [0003] The existing tire pressure monitoring system mainly adopts the indirect type and the direct type. Compared with the indirect type, the direct type has many advantages. The control board is used as the upper computer, and then the tire pressure monitoring sensors are set one by one in the four tires, and the effect of monitoring tire pressure data is realized through wireless transmission between the two. ...
