Description

Technical Field

[0001] This utility model relates to the field of integrated driver and trailer technology for heavy-duty commercial vehicles, specifically to a tire pressure monitoring device for integrated driver and trailer heavy-duty commercial vehicles. Background Technology

[0002] A heavy-duty commercial vehicle articulated trailer consists of a semi-trailer tractor and a semi-trailer with angular movement linkage. The tractor and trailer communicate via wiring harnesses.

[0003] Currently, in the market, heavy-duty commercial vehicle articulated trailers are designed independently by two companies, and the communication information between the main vehicle and the trailer is not shared. Existing tire pressure monitoring systems can only monitor the tire pressure and other related information of each tire on the chassis, but cannot monitor the tire pressure and other information of the superstructure tires. When the tire pressure or temperature of a wheel on the superstructure is abnormal during vehicle operation, the driver cannot obtain the abnormal tire information in the cab in time. The problem can only be discovered and repaired when a tire blowout or other failure affects the normal operation of the vehicle, which increases the risk of accidents and maintenance costs.

[0004] Therefore, there is a need to invent a tire pressure monitoring device for heavy-duty commercial vehicles that integrates the main engine and trailer to solve the problem of high risk and high maintenance cost caused by the inability of articulated trains of heavy-duty commercial vehicles to detect trailer tire information in a timely manner. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a tire pressure monitoring device for heavy commercial vehicles that integrates the main and trailer parts.

[0007] The trailer side is equipped with a tire pressure controller and multiple tire pressure sensors. The tire pressure sensors are installed on each tire on the trailer side. The tire pressure sensors are wirelessly connected to the tire pressure controller. The tire pressure controller is connected to the tire pressure transmission module via a CAN bus. The tire pressure transmission module is connected to the VTCM controller.

[0008] Preferably, the multimedia screen and instrument panel are installed in the driver's cab on the driver's side of the vehicle, and the multimedia screen and instrument panel display the tire pressure information and message information sent by the VTCM controller.

[0010] Preferably, the tire pressure controller is equipped with a high-frequency receiving antenna, which is either built into the tire pressure controller or connected to an external lead-out connector.

[0011] Preferably, the tire pressure transmission module is installed on the side chassis of the trailer, and the tire pressure transmission module is connected to the VTCM controller via a CAN bus.

[0012] Preferably, the tire pressure controller is connected to a secondary instrument via a CAN bus, and the secondary instrument is mounted on the side chassis of the trailer.

[0013] This utility model has the following beneficial effects:

[0014] This utility model designs an integrated tire pressure monitoring device for heavy-duty commercial vehicles, embodying the concept of integrated main and trailer design. The main vehicle and trailer are integrated into a single vehicle design. Real-time and accurate display and monitoring of tire pressure, temperature, and other information for each tire of both the main vehicle and trailer can be achieved on the multimedia screen and instrument panel inside the cab. When any tire pressure or temperature of either the main vehicle or trailer becomes abnormal, an alarm message will be displayed on the tire pressure monitoring interface of the main vehicle's multimedia screen and instrument panel. The device provides precise information down to the specific location of each tire and its real-time tire pressure and temperature.

[0020] The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1-3 As shown, a tire pressure monitoring device for a heavy-duty commercial vehicle integrating a driver and trailer includes a driver side 1 and a trailer side 2. The driver side 1 is equipped with a VTCM controller 1.1, a multimedia screen 1.2 and an instrument panel 1.3. The VTCM controller 1.1 is an on-board transmission controller, and the VTCM controller 1.1 is connected to the multimedia screen 1.2 and the instrument panel 1.3.

[0022] The multimedia screen 1.2 and the instrument panel 1.3 are installed in the driver's cab on the main vehicle side 1. The multimedia screen 1.2 and the instrument panel 1.3 display the tire pressure information and message information sent by the VTCM controller 1.1.

[0023] The VTCM controller 1.1 is used to receive tire pressure signals and message information transmitted from the trailer side 2, and send them to the multimedia screen 1.2, instrument panel 1.3 and other hardware for relevant information processing and display.

[0024] Multimedia screen 1.2 is used to receive relevant tire pressure information from VTCM controller 1.1, and displays the received tire pressure information on the screen. For abnormal information, it provides different levels of warning prompts (red, yellow, etc.) to the tire pressure monitoring system on media screen 1.2. Figure 2 As shown.

[0025] Instrument 1.3 is used to receive relevant tire pressure information from VTCM controller 1.1, and to display alarm prompts and alarm icons in the form of pop-up alarm windows for abnormal information, such as... Figure 3 As shown.

[0026] The trailer side 2 is equipped with a tire pressure controller 2.3, a repeater 2.2, a secondary instrument 2.4, a tire pressure transmission module 2.5, and multiple tire pressure sensors 2.1. The tire pressure sensors 2.1 are installed on each tire of the trailer side 2. The tire pressure sensors 2.1 are wirelessly connected to the tire pressure controller 2.3. The tire pressure controller 2.3 is a TPMS tire pressure monitoring host installed on the chassis. The tire pressure controller 2.3 is connected to the tire pressure transmission module 2.5 via a CAN bus. The tire pressure transmission module 2.5 is connected to the VTCM controller 1.1.

[0027] The tire pressure sensor 2.1 is connected to the repeater 2.2 via radio frequency, and the repeater 2.2 is connected to the tire pressure controller 2.3 via radio frequency.

[0028] The tire pressure controller 2.3 is equipped with a high-frequency receiving antenna, which can be built into the tire pressure controller 2.3 or connected to an external lead-out connector.

[0029] The tire pressure transmission module 2.5 is installed on the chassis of the trailer side 2. The tire pressure transmission module 2.5 is connected to the VTCM controller 1.1 via the CAN bus.

[0030] The tire pressure controller 2.3 is connected to the auxiliary instrument 2.4 via the CAN bus. The auxiliary instrument 2.4 is installed on the chassis of the trailer side 2.

[0031] Tire pressure sensor 2.1 transmits tire temperature and pressure signals to the host via radio frequency. When alarm data is detected, tire pressure sensor 2.1 increases the frequency of data transmission; during initialization, it receives a low-frequency initialization command.

[0032] High-frequency receiving antenna: The receiving antenna can be integrated into the tire pressure controller 2.3, or it can be directly led out from the connector of the tire pressure controller 2.3 to receive the pressure and temperature signals transmitted by the tire pressure sensor 2.1 to the repeater 2.2 and transmit them to the tire pressure controller 2.3.

[0033] The tire pressure controller 2.3 uses a TPMS host to receive and process the signals from the tire pressure sensor 2.1, and then performs CAN communication.

[0034] The repeater 2.2 sends the information to the trailer tire pressure sensor 2.1 first, and then transmits it to the tire pressure controller 2.3 via radio frequency.

[0035] When the vehicle VTCM controller 1.1 receives the tire pressure, temperature, and other status information of each tire of the trailer from the tire pressure transmission module 2.5 on the trailer side 2, the VTCM controller 1.1 will make a judgment, process the relevant data, and send it to the multimedia display screen 1.2 for display of relevant information. It will also issue warnings for abnormal data to remind the driver to take emergency measures, thereby ensuring that the status of each tire is within the normal range and ensuring driving safety.

[0036] The VTCM controller 1.1 needs to determine the tire pressure and temperature status of each tire on the tractor and trailer based on multiple conditions. This is mainly used to confirm when the information is displayed normally, when a yellow general warning is issued, and when a red severe warning is issued.

[0037] Specifically: When the tire pressure and temperature information of each tire on the main vehicle and trailer is displayed in yellow on the multimedia screen 1.2, it indicates that the current tire pressure and temperature are in a state of normal low pressure or normal high pressure, which is a primary warning and there is no safety risk.

[0038] When the tire pressure and temperature information of each tire on the main vehicle and trailer is displayed in red on the multimedia screen 1.2 and instrument panel 1.3, it indicates that the current tire pressure and temperature are in a state of severe low pressure or severe high pressure, which is a warning sign of serious safety risks and requires immediate emergency treatment of the faulty tire.

[0039] The multimedia screen 1.2 displays yellow warnings for low tire pressure and high tire pressure for each tire on both the main vehicle and the trailer, indicating these warnings.

[0040] The multimedia screen 1.2 and instrument panel 1.3 provide red warnings for severe low pressure and severe high pressure for each tire of the main vehicle and trailer, displaying tire pressure and temperature information.

[0041] This utility model is not limited to the above-described embodiments. Anyone should know that any structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
