Heavy Duty Vehicles Truck TPMS RF Wireless Transmission Tpms Monitor

OEM Trucks TPMS with UDS diagnostics IP67 rated and 0-150 PSI range for heavy-duty vehicles

The truck-mounted tire pressure monitoring system is a factory-installed direct-type TPMS designed for heavy-duty trucks and tractor-trailers. It monitors tire pressure and temperature across all tires in real time and features multi-level early warnings for air leaks, high temperatures, and low pressure; The system has undergone rigorous reliability testing on the complete vehicle, integrates with the vehicle’s CAN bus network and fleet management platforms, effectively prevents tire blowouts, extends tire life, reduces fuel consumption, meets commercial vehicle regulatory requirements, and provides proactive tire safety protection for long-haul logistics, construction, and hazardous materials transport vehicles.

I. Product Overview

The truck factory-installed TPMS is a direct-type tire pressure monitoring system pre-installed on the production line by vehicle manufacturers for heavy-duty commercial vehicles. It is a standard safety component and is compatible with tractor trucks, cargo trucks, dump trucks, concrete mixer trucks, and hazardous materials transport vehicles. It supports coordinated monitoring of the tractor unit and multi-axle trailers, complies with national commercial vehicle regulations and OEM vehicle reliability standards, and comes factory-calibrated with CAN bus integration and vehicle validation—distinguishing it from aftermarket TPMS systems installed after vehicle sale.

The system collects real-time data on tire pressure, tire temperature, and sensor battery voltage for each wheel, transmitting this information via radio frequency to the vehicle’s ECU. The data is integrated into the vehicle’s instrument cluster, the vehicle’s CAN network, and the fleet’s T-Box remote platform, enabling both on-site driver alerts and remote fleet monitoring. This helps prevent tire blowouts at high speeds and uneven tire wear, while reducing fuel consumption and operational costs.

II. System Components

1. Wheel Sensor (Heavy-Duty Valve-Mounted Sensor)

   Installed on the tire valve stem with an M14/M16 heavy-duty threaded structure; features a built-in MEMS pressure chip, temperature sensor, acceleration wake-up module, and RF transmitter; protection rating: IP68/IP69K; Operating temperature range: -40°C to +125°C; resistant to severe vibration, salt spray, mud, water, and brake dust; supports heavy-duty, high-pressure measurement ranges; features a long-life industrial battery; supports automatic wheel position identification and calibration.

   Optional built-in tire-mounted sensors provide more accurate tire temperature measurements, suitable for long-term fleet management.

2. RF Receiver Module (TPMS Receiver)

   Installed in the cab or on the chassis, it receives RF signals from sensors on each wheel, demodulates them, and forwards them to the TPMS main control ECU; for multi-axle vehicles, a relay amplifier can be configured to address long-distance transmission issues with trailers and signal shielding caused by steel rims.

3. TPMS Main Control ECU

   The system’s core controller, responsible for signal parsing, wheel position management, threshold determination, fault diagnosis, and CAN/CAN FD bus communication; can integrate with the vehicle’s instrument cluster, VMS, T-BOX, and ADAS systems.

4. Human-Machine Interface (HMI) (Instrument Cluster Display)

   Integrates with the vehicle’s original instrument cluster; an optional standalone external display is available; Real-time display of tire pressure and temperature by axle and by wheel; audible and visual alarms (under-pressure, over-pressure, high temperature, sensor loss, low battery, communication failure).

5. Remote Platform (T-BOX Integration)

   Uploads data to the fleet management platform, supporting remote monitoring of vehicle tire status, push notifications for anomalies, tire data storage, and statistical reporting to enable predictive tire maintenance.

III. Core Functions

• Real-time Monitoring: Continuously collects tire pressure, tire temperature, and sensor battery level data from all wheel positions while driving or idling; supports multi-axle expansion, covering the tractor unit plus 1–3 trailers, with support for up to several dozen wheel positions.
• Multi-Level Alert Strategy
  • Under-pressure warning: Tire pressure falls below a set threshold (e.g., 20% below cold pressure)
  • Overpressure and Overheating Alerts (brake overheating)
  • Rapid Air Leak Emergency Alert (sudden pressure drop, high risk of tire blowout)
  • Self-diagnostic alerts for sensor disconnection, low battery voltage, and communication failures
• Automatic Wheel Position Recognition: Automatically identifies wheel positions while the vehicle is in motion; supports quick recalibration after tire changes or wheel repositioning without complex tools.
• Vehicle-Wide CAN Bus Integration: Data is integrated into the vehicle’s network; fault codes are written to the vehicle diagnostic system and can be read by vehicle diagnostic tools, meeting OEM off-line inspection and after-sales maintenance requirements.
• Self-diagnostic function: The system performs a self-test upon power-up and diagnoses real-time communication faults in sensors, receivers, and the ECU; fault information is stored for easy troubleshooting during after-sales service.
• Remote fleet management: Tire pressure and temperature data is uploaded to the cloud, allowing fleets to monitor tire health across multiple vehicles simultaneously and generate reports on tire lifespan and anomalies to support preventive maintenance.

IV. Product Advantages (Core Highlights for OEM Front-End Installation)

1. Vehicle-Level Reliability Validation:

   Completed a full suite of automotive-grade tests at the OEM facility, including vibration, high and low temperature, salt spray, water immersion, and EMC (electromagnetic compatibility) testing. Meets the demanding conditions of commercial vehicles, such as severe vibrations and heavy loads, and complies with regulations and standards including GB, ECE R141, and SAE J2848, enabling vehicle-level certification.

2. Native Vehicle Integration:

   Deeply integrated with the instrument cluster, vehicle electronic control systems, and T-BOX. Wiring harnesses and mounting locations are planned concurrently during the vehicle design phase, ensuring no damage to the original vehicle structure, eliminating the risks associated with aftermarket modifications, and ensuring inclusion in the vehicle’s warranty system.

3. Safety and Cost-Saving Benefits

   • Safety: Significantly reduces the risk of tire blowouts at high speeds, which is particularly critical for vehicles transporting hazardous materials;
   • Tires: Maintains standard tire pressure, reduces uneven wear, and extends tire life by approximately 15%–20%;
   • Fuel: Underinflation significantly increases rolling resistance; maintaining stable tire pressure reduces fuel consumption;
   • Operations and Maintenance: Detects slow air leaks early, reduces roadside breakdowns, and lowers fleet emergency repair costs.

4. Suitable for Heavy-Duty Trucks in Multiple Scenarios:

   Supports complex operating conditions such as empty loads, full loads, hill climbing, and continuous braking; tire pressure alert thresholds can be set independently for different axle loads.

V. Application Scenarios

• Long-haul trunk logistics with tractor-trailers (flatbed, box, or tank trailers)
• Construction dump trucks and concrete mixers
• Hazardous chemical transport vehicles (subject to strict regulatory safety requirements)
• Heavy-duty specialty trucks for mining, ports, and other applications.
