Embodiment 1

[0048] This embodiment discloses a method for identifying the position of the front and rear wheels of a tire pressure sensor, see figure 1 This method uses the sensor signal sent by the tire pressure sensor 1 mounted on the wheel 2 to identify the front and rear wheel positions of the tire pressure sensor.

[0049] Such as figure 2 As shown, the method for identifying the position of the front and rear wheels of the tire pressure sensor of this embodiment includes the following steps:

[0050] S11. Acquire a first sensing signal for indicating that the tire pressure sensor is located at the first angular position and a second sensing signal for indicating that the tire pressure sensor is located at the second angular position, and a corresponding tire pressure sensor identification code.

[0051] In a specific embodiment, in a specific embodiment, such as figure 1 As shown, the so-called first angular position may be the position where the tire pressure sensor is located in front of...

Embodiment 2

[0098] This embodiment also discloses a tire pressure sensor front and rear wheel position identification device, such as Picture 9 As shown, the device includes: an acquisition module 100, a recording module 200 and a processing module 300, wherein:

[0099] The acquiring module 100 is configured to acquire a first sensing signal used to characterize the tire pressure sensor at a first angular position, a second sensing signal used to characterize the tire pressure sensor at a second angular position, and a corresponding tire pressure sensor identification code; The recording module 200 is used to record the first number of acquired first sensing signals and the second number of second sensing signals and the corresponding tire pressure sensor identification code; the processing module 300 is used to record the first number of sensing signals The first number and the second number of the second sensing signal and the corresponding tire pressure sensor identification code determi...

Embodiment 3

[0110] This embodiment also discloses a tire pressure sensor front and rear wheel position identification system, such as Picture 10 As shown, the system includes: a tire pressure sensor 1000, a sensor signal receiving device 2000 and a processor 3000, where:

[0111] The tire pressure sensor 1000 is used to collect and send a first sensing signal including a first angular position and a second sensing signal including a second angular position. In a specific embodiment, a tire pressure sensor 1000 provided with an acceleration sensor may be selected, the processor 3000 may use the wheel acceleration value to identify the angular position of the tire pressure sensor 1000 on the wheel, and the tire pressure sensor 1000 may determine the preset angular position The information is added to the signal sent by the tire pressure sensor 1000, for example, the value "1" is added to represent the first angular position, and the angle value "0" is the second angular position. When it is r...

Abstract

The invention provides a method, device and system for identifying front and rear wheel positions of tire pressure sensors. The method includes the steps that first sensing signals used for representing the first angle positions of the tire pressure sensors, second sensing signals used for representing the second angle positions of the tire pressure sensors and corresponding tire pressure sensor identification codes are obtained; a first frequency of the obtained first sensing signals, a second frequency of the obtained second sensing signals and the corresponding tire pressure sensor identification codes are recorded; and according to the first frequency of the obtained first sensing signals, the second frequency of the obtained second sensing signals and the corresponding tire pressure sensor identification codes, the front and rear wheel positions of the tire pressure sensors corresponding to the identification codes are determined. Therefore, under the condition that cost is not increased, the complexity degree of processing of identified data of the front and rear wheel positions of the tire pressure sensors is reduced.

Description

Technical field [0001] The invention relates to the field of automobile tire monitoring, in particular to a method, device and system for identifying the positions of front and rear wheels of a tire pressure sensor. Background technique [0002] Car tire pressure real-time monitoring system (TPMS) is mainly used for real-time automatic monitoring of tire pressure when the car is running, and alarms for tire leaks and low pressure to ensure driving safety. It is the life of drivers and passengers Safety assurance early warning system. The tire pressure monitoring module installed on the car tire is the tire pressure sensor. [0003] TPMS first identifies each tire of the vehicle, and checks whether the corresponding tire has air leakage or low air pressure through the tire pressure sensor of each tire of the vehicle. Among them, in the tire identification process of TPMS, the front and rear wheels need to be identified There are three commonly used identification methods. [0004] ...
