Problems solved by technology
[0008] As far as this technical solution is concerned, it can be seen from the signal strength of the Z-axis acceleration sensor that the Z-axis acceleration sensor has a wheel rotation speed offset (Offset) with the rotation speed of the wheel. The sinusoidal (Sine) waveform is larger than the offset (Offset), so it is very difficult to perceive the period of the sinusoidal waveform, and there is a problem of adding a circuit for sensing the period in the sinusoidal (Sine) waveform of the signal

The invention provides a tire pressure monitoring system, in particular to a device and method for transmitting tire position information together with tire pressure state related information. The present invention provides a logic that calculates the rotation angle between a plurality of geomagnetic field sample information obtained from the geomagnetic sensor, calculates the rotation direction, and determines the left or right position of the tire based on the accumulated times of the rotation direction. According to the present invention, the geomagnetic sensor is used to run the optimized tire position determination logic while driving, even when driving on a dangerous road, the accuracy of the determination of the left or right position of the tire is provided, and the calculation of the position determination algorithm (algorithm) is reduced. The number minimizes the current consumption and provides the effect of reducing the price of TPMS products due to the reduction in the number of parts.
Description
technical field [0001] The present invention relates to a tire pressure monitoring system that senses tire pressure and displays the tire pressure to the driver or the location of the tire where low pressure occurs, and in particular relates to a tire pressure monitoring system that confirms the location of the tire based on information sensed by a geomagnetic sensor An apparatus and method for transmitting tire position information whether it is the left side or the right side of the vehicle. Background technique [0002] The so-called tire pressure monitoring system (TirePressureMonitoringSystem: TPMS) refers to a device for sensing tire pressure and maintaining an appropriate pressure. It is composed of a sensor and a control device. Transmit the sensing value and the inherent identification name (ID) of the sensor to the control device installed on the vehicle; the control device receives the radio frequency data sent from the sensor and the information of the vehicle, j...
