Problems solved by technology

Generally, after the internal temperature of the tire rises due to the driving and braking of the vehicle, if the vehicle does not stop continuously within one hour, but repeatedly drives and stops within the reference time, there will be about 2 hours between the internal temperature of the tire and the external air temperature. An error of ~3 degrees, and an alarm to notify the tire low pressure status has been set, which will also cause an error of the set value (Error Margin)

Embodiment Construction

[0032] The invention provides a tire pressure monitoring device that can calculate the parking time of the vehicle in a system environment where the external air temperature of the vehicle cannot be used (or cannot be ensured), and use this to estimate or set the external air temperature. Therefore, the estimated or set outside air temperature can also be used to flexibly monitor tire pressure changes in system environments where the vehicle's outside air temperature cannot be used (or cannot be guaranteed). In addition, it reduces the parasitic current consumed by the sensor receiver of the present invention to minimize the power consumption used in the vehicle.

[0033] An embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] figure 2 It is a block diagram showing the internal structure of a tire pressure monitoring device according to an embodiment of the present invention.

Abstract

Provided is an apparatus for estimating an external temperature for monitoring a tire pressure. The apparatus includes a sensor transmitter configured to transmit stop time information which is obtained by measuring a stop time of a vehicle at certain intervals, by using wireless communication, and a sensor receiver configured to receive the stop time information through the wireless communication, and measure the external temperature by using the received stop time information.

Description

technical field [0001] The invention relates to a tire pressure monitoring device and a method thereof. Background technique [0002] In order to enhance the durability, ride quality, braking force, etc. of the tires mounted on the vehicle, conditions such as the air pressure and temperature of the tires must be maintained at reasonable levels. Therefore need a kind of device that can monitor above-mentioned tire air pressure and temperature. These devices are usually called tire pressure monitoring systems (Tire Pressure Monitoring System: TPMS) in automotive engineering. [0003] figure 1 It is a block diagram showing the structure of a TPMS sensor provided on a common TPMS. [0004] according to figure 1 , TPMS sensor consists of pressure sensor 11 (Pressure Sensor), temperature sensor 13 (Temperature Sensor), vehicle speed and rotation sensor 15 (Acceleration Sensor), battery voltage sensor 17 (Supply Voltage Sensor), controller 19, RF transmitter 21 (RF Transmitte...
