EBPMS | Electronic Braking Performance Monitoring System

Electronic Brake Performance Monitoring Systems (EBPMS) provide a dynamic, data-driven approach to monitoring trailer braking systems. By calculating a Braking Performance Value (BPV), EBPMS ensures compliance with safety standards and enhances safety and operational efficiency.

What is the Braking Performance Value (BPV)?

The Braking Performance Value (BPV) is a predictive measure of braking efficiency, representing the braking effort a trailer is capable of achieving at the maximum demand pressure of 6.5 bar. Expressed as a percentage, the BPV must be 45% or greater to meet compliance standards.

How is BPV Calculated?

1. Braking Events: EBPMS continuously records data during real-world braking events, including:
   • Average Demand Pressure: The pressure applied to the braking system, typically ranging from 1-2 bar.
   • Braking Effort: The force generated in response to the demand pressure.
   • Load and Road Angle: Factors influencing braking performance under different conditions.
2. Data Analysis: Each braking event provides data points, and the system evaluates these to establish a trend of braking effort against demand pressure.
3. Prediction Line: Using the collected data, a predictive line is generated to represent expected braking performance. This line begins at 0 bar and extends to the maximum demand pressure of 6.5 bar.
4. Extrapolation: The BPV is calculated by extrapolating the braking effort to 6.5 bar along the prediction line. This value provides a reliable measure of the trailer's braking performance under maximum demand conditions.

How Does EBPMS Work?

EBPMS continuously monitors and analyses data during normal vehicle operations. Key features include:

• Real-Time Data Collection: Metrics such as demand pressure, braking effort, load, and road angle are captured during every braking event.
• Performance Evaluation: Braking events are used to calculate a BPV that represents overall system efficiency.
• Proactive Alerts: If braking performance trends toward non-compliance, the system flags anomalies, enabling timely maintenance.

Why EBPMS is Essential

• Enhanced Safety: Real-time monitoring ensures early detection of braking inefficiencies, reducing the risk of brake-related incidents.
• Operator Compliance: From April 2024, the DVSA will require fleets to:
  • Conduct 4 laden Roller Brake Tests (RBTs) annually, or
  • Perform 1 annual RBT, supplemented by EBPMS data.
• Operational Efficiency: By providing actionable insights, EBPMS allows fleet operators to predict maintenance needs, minimise downtime, and ensure vehicles remain operational.

Preparing for 2025: Key Takeaways

• Equip Your Fleet with EBPMS: Ensure your trailers are fitted with compliant systems.
• Plan for Compliance: Choose between 4 annual laden RBTs or EBPMS-supported testing.
• Optimise Maintenance: Use BPV insights to improve scheduling and minimise downtime.
