Problems solved by technology

[0010] However, as mentioned above, when the LF starter used corresponds to the TPMS sensor installed on each tire, it not only increases the cost of the system, but also leads to the problem that the wiring connected to the LF starter is more complicated.
Using a dual-axis accelerometer requires the vehicle to track the position while driving for a long time, and there is a problem that it takes a long time to identify the sensor

Abstract

The invention relates to an apparatus for recognizing position sensor in a tire pressure monitoring system and a method thereof. A TPMS sensor equipped with an LF starter and two LF antennas is utilized for recognizing a sensor position in a short time. The connection wiring of the LF starter is simple and less LF starters help to save the cost of equipment. Moreover, no accelerometer is needed by the TPMS sensor. Through the two LF antennas for position recognization, the position can be recognized in a short time when a vehicle is not running.

Description

technical field [0001] The present invention relates to a sensor position identification and method of a tire pressure monitoring system, specifically using a TPMS sensor with an LF starter and two LF wires to detect the sensor position of the tire pressure monitoring system in a short time Recognizers and their methods. Background technique [0002] A general tire pressure monitoring system (TPMS: Tire Pressure Monitoring System, hereinafter referred to as 'TPMS') uses the status of the tires installed on the car to inform the driver to prevent accidents. [0003] The TPMS center installed on the tire sends the tire status information to the TPMS control unit installed on the vehicle. After receiving the status of each tire, the control unit displays or emits a warning sound on the car dashboard to inform the driver. [0004] The TPMS sensor uses radio frequency (RF) to transmit data such as tire pressure status, tire temperature, and sensor ID. [0005] At this time, the...
