Tire locking detection method and device based on UWB technology

Abstract

The embodiment of the invention provides a tire locking detection method and device based on the UWB technology, and the method comprises the steps: determining the distance between each base stationlabel and a positioning label according to the time information of each base station label for receiving a UWB pulse signal transmitted by the positioning label; determining a tire locking detection result according to the change condition of the distance between each base station label and the positioning label, wherein the base station labels are dispersedly arranged around the tire and are independent of the tire, and the base station labels do not rotate along with the rotation of the tire; the positioning label is arranged on the tire and rotates along with the rotation of the tire. According to the embodiment of the invention, tire locking detection is carried out through an ultra-wideband wireless communication technology; locking judgment is carried out by judging whether the relative positions of the base station label and the positioning label are changed or not, the burden of replacing the wheel speed sensor can be relieved, the problems of inaccurate detection of the wheelspeed sensor, failure of the wheel speed sensor and the like caused by various factors are avoided, tire locking detection is more reasonable, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a tire lock detection method, device, electronic equipment and storage medium based on UWB technology. Background technique [0002] Tire lockup means emergency braking of the wheel, that is to say, the brake clamps the tire. At this time, the tire does not move relative to the brake, and the tire slides relative to the ground. When the vehicle is running at a high speed, if the tire locks up, many dangerous situations may occur, such as sideslip, loss of control, and failure to avoid obstacles. In severe cases, the vehicle may turn around and break into other lanes. Thereby traffic danger takes place, endanger life safety. [0003] The existing tire lock detection uses the wheel speed sensor to detect the speed of each wheel of the vehicle. However, if the wheel signal rotor is deformed, toothed, worn, cracked, the sensor probe is fouled, or the sensor coil is open or...

Problems solved by technology

When the vehicle is running at a high speed, many dangerous situations may occur in the event of tire lockup, such as sideslip, loss of control, and failure to avoid obstacles. In severe cases, the vehicle may turn around and break into other lanes. resulting in traffic hazards, endangering life safety

[0003] The existing tire lock detection uses the wheel speed sensor to detect the speed of each wheel of the vehicle. However, if the wheel signal rotor is deformed, toothed, worn, cracked, the sensor probe is fouled, or the sensor coil is open or short-circuited, it will cause the vehicle to lock. There is a problem with the dead detection, and the replacement of parts is cumbersome. If this existing tire lock detection method cannot be improved, in the long run, it is easy to cause inaccurate detection caused by parts damage, resulting in traffic hazards and frequent replacement. Parts will also bring a burden to users, thereby reducing user experience
