Technical Field

[0001] This utility model belongs to the automotive field, specifically relating to a tire condition monitoring system suitable for commercial vehicles. Background Technology

[0002] Commercial vehicles, due to their large load capacity and long operating time, are prone to tire pressure and temperature issues. Both of these conditions can lead to tire blowouts. Therefore, tire condition monitoring is crucial for driver safety, and there is an urgent need for vehicles to be equipped with tire condition monitoring systems. Currently, commercial vehicles are not equipped with such monitoring systems. Utility Model Content

[0003] The purpose of this invention is to provide a tire condition monitoring system suitable for commercial vehicles, which allows drivers to monitor tire condition in real time, reduce vehicle accidents caused by tire problems, improve driver safety, and provide a more comfortable user experience.

[0004] This utility model is achieved through the following technical solution:

[0005] A tire condition monitoring system for commercial vehicles includes a tire pressure sensor, a repeater, a tire pressure controller, and a combination instrument.

[0006] Tire pressure sensors are installed inside the tires to monitor their condition in real time. The signals are transmitted wirelessly, and a repeater on the chassis amplifies the signals before finally transmitting them to the tire pressure controller installed in the driver's cab. The tire pressure controller processes the collected data and transmits it to the instrument cluster via the vehicle bus. The instrument cluster receives the information and displays the real-time tire condition. In case of tire abnormalities, it can alert the driver through sound and light.

[0007] With this invention, drivers can monitor tire status in real time. When tire status is abnormal, timely measures can be taken to avoid more serious consequences such as tire blowout. Attached Figure Description

[0010] To make the objectives and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figure 1-2 The present invention will be further described in detail with reference to the embodiments and examples.

[0011] The tire condition monitoring system of this utility model consists of a sensor (1), a repeater (2), a controller (3), an instrument (4), and related wiring harnesses. The system is installed and arranged on the vehicle as follows: Figure 1 As shown, sensor (1) is installed inside the tire, one for each tire; repeater (2) is installed on the vehicle chassis beam; controller (3) is installed below the passenger-side dashboard; and instrument (4) is installed on the driver-side dashboard. The working principle of the tire condition monitoring system is as follows: Figure 2 The description is as follows:

[0012] like Figure 2 As shown, the sensor's function is to collect tire status data and transmit the information to the repeater. It consists of a SOC main chip, an SMD crystal oscillator, an antenna, and a battery. The SOC main chip processes the collected information, the SMD crystal oscillator monitors the tire status through the piezoelectric effect, the antenna transmits the processed information from the SOC main chip to the repeater, and the battery powers the sensor. The repeater receives attenuated signals, processes and recovers them, and retransmits them to prevent signal distortion due to attenuation and interference during transmission, especially over long distances. It consists of a receiver, a bandpass filter, a voltage regulator chip, a voltage regulator, and a transmitter. The receiver receives the RF signal emitted by the sensor, the bandpass filter filters the sensor's frequency band signal to eliminate interference, the voltage regulator chip and voltage regulator maintain voltage stability to ensure signal stability and reliability, and the transmitter transmits the processed and recovered signal. The information is sent to the controller; the controller processes the received information and transmits it to the instrument cluster via the vehicle's CAN bus. It consists of a SOC main chip, receiver, bandpass filter, voltage regulator chip, voltage regulator, and CAN transceiver. The SOC main chip processes, integrates, judges, and sends the collected information to the instrument cluster via the vehicle's CAN bus. The receiver receives RF signals from the repeater. The bandpass filter filters sensor frequency signals to eliminate interference. The voltage regulator chip and voltage regulator maintain voltage stability and ensure signal stability and reliability. The CAN transceiver communicates with the vehicle and transmits tire information to the instrument cluster. The instrument cluster displays the real-time tire status and provides audible and visual alarms when tire conditions are abnormal. It consists of an LCD screen and a speaker. The LCD screen displays tire pressure, tire temperature, and fault information, while the speaker provides a buzzer alarm when tire conditions are abnormal.

[0013] As shown in Table 1, the controller needs to judge the collected information. When the tire condition shows an abnormality as shown in the table, the instrument needs to issue an alarm as required by the table.
