🚛 From Reactive to Predictive Maintenance

Traditional maintenance schedules rely on fixed intervals — every 6 months, every 50,000 km, etc. Predictive maintenance uses **real-time data from telematics systems** to determine exactly when each component needs attention. This approach prevents unexpected failures, reduces spare part waste, and maximizes uptime.

📡 Data Sources for Trailer Diagnostics

• EBS System: Brake wear sensors, mileage, temperature, and pressure data.
• TPMS: Continuous tyre pressure and temperature feedback.
• Axle Load Sensors: Detect overload or uneven distribution.
• Hub RPM & Vibration Sensors: Identify bearing wear patterns.
• GPS/Telematics: Provide route-based stress and usage profiling.

🧠 How AI Models Detect Early Failures

Machine learning algorithms compare incoming data to normal operating baselines. When patterns deviate — such as rising brake temperature or irregular vibration — the system flags potential failure. Fleet dashboards can even estimate remaining useful life (RUL) for parts like brake pads or tyres.

🔍 Example: Brake System Analytics

Parameter	Normal Range	Warning Indicator	Predictive Insight
Brake temperature	50–150°C	>180°C	Sticking caliper or dragging brake
Pad wear	<5 mm change / 10k km	Rapid wear trend	Check alignment or load imbalance
Air pressure fluctuation	±0.3 bar	Unstable readings	Compressor or valve malfunction

📊 Cloud-Based Data Processing

Modern platforms aggregate millions of data points per trailer. Through edge computing and IoT gateways, only the most relevant diagnostics are sent to the cloud — optimizing bandwidth and privacy. Fleet managers receive **predictive alerts**, not just raw data.

⚙️ Benefits of Predictive Maintenance

• ⏱️ Up to 30% reduction in unplanned downtime.
• 💰 10–20% savings in spare part inventory.
• 🛡️ Higher road safety and EBS reliability.
• 🌍 Lower emissions by maintaining optimal rolling resistance.

🧩 Integration with Fleet Management Systems

Telematics gateways can sync predictive alerts with ERP or TMS software. This allows automatic scheduling of service appointments and maintenance record logging — fully digitizing the workflow.

🏁 Final Thoughts

Predictive maintenance is no longer optional — it’s the new standard for competitive, data-driven fleets. By analyzing continuous trailer telemetry, operators can transition from **reactive repair** to **proactive optimization**, turning maintenance into a strategic advantage.
