Problems solved by technology
However, for tire-outside tire pressure detectors, because the angles of the air nozzles are different, and the angles after rotation and assembly are not fixed, the X and Z-axis sensor data of the detector itself cannot be positioned using the PAL method.
[0006] To sum up, if the tire pressure detector cannot be accurately positioned after the car assembly process, then when the car is driving in the future, the tire pressure detection system will continue to detect the tires in errors , causing the car to be extremely dangerous in driving

The invention relates to a multi-antenna tire pressure detector automatic positioning device, which comprises a plurality of tire pressure detectors, a receiver and a central processing unit, the plurality of tire pressure detectors are arranged on each tire of a vehicle, each tire is provided with a tire pressure detector, each tire pressure detector is internally provided with a signal transmitting unit, and the central processing unit is connected with the receiver. The receiver comprises two antennas and a built-in receiving control unit, a first phase angle and a second phase angle are respectively formed between signals sent by each tire pressure detector and each antenna, and the receiving control unit receives each first phase angle and each second phase angle. And the phase difference of a plurality of different parameter values can be obtained through the operation of an operation unit built in the central processing unit, so that the position of each tire is judged, and finally, the information calculated by the operation unit of the receiver is received by a signal receiving unit built in the central processing unit and is displayed to finish the positioning.
Description
technical field [0001] The present invention is an automatic positioning device for a multi-antenna tire pressure detector, which refers to the technology applied in the automotive field in detail. The relative angle, and then accurately and clearly identify the front and rear, left and right positions of each tire, and determine whether the positioning of each tire is accurate, which is an invention with excellent practicability. Background technique [0002] In recent years, we have attached great importance to and advocated traffic safety. Whether it is a pedestrian on foot or a driver, there are many traffic rules that must be followed. Among them, according to the regulations in recent years, new passenger cars and small trucks must be equipped with The "Tire Pressure Detection Assist System" not only improves the overall safety of passersby, but also ensures the stability of the vehicle at high speed. [0003] Therefore, in the process of production and assembly, the ...
