Preempt breakdowns

Catch the fault before it takes the bus off  the road

Diagnostic AI continuously analyzes vehicle condition across your fleet, identifying emerging faults early enough to prioritize intervention and prevent avoidable breakdowns

X-ray style side view diagram of a bus showing an orange highlighted battery pack. A data box shows battery pack details: usable capacity dropping from 340 kWh to 310 kWh, state of health at 91%, load balancing labeled bad, charging performance labeled good, and a status button labeled 'Check at next scheduled stop.' A graph titled 'Usable Capacity vs. Vehicle Age' shows measured, 3-year forecast, warranty threshold, and declared capacity lines across 5 years, with current capacity 44 kWh above the warranty threshold.

Every breakdown starts long before the bus stops

A fault develops for weeks before the warning light appears.
Thousands of vehicle signals, but no clear indication which bus needs attention first.
A roadside recovery that could have been a planned workshop visit.
Most maintenance systems become useful only once a fault code fires. By then, the disruption has already happened.
Preventing breakdowns starts with understanding what is developing before conventional diagnostics recognise a fault.

Detect the condition, not the consequence.

Vehicle conditions change continuously. Diagnostic AI monitors those changes over time, identifying developing faults while there’s still time to plan maintenance instead of responding to failure.

Every developing fault arrives ready for action

Every developing issue becomes a condition report, bringing together the diagnosis, supporting evidence, engineering reasoning, and recommended action before the vehicle reaches the workshop.

Every condition report shows:
What is developing
Why it matters
What to inspect
What to do next

More planned maintenance. Fewer operational surprises.

Detect faults before they become breakdowns
Give operations teams earlier visibility into fleet health
Keep more buses available for service
Protect operational performance
Replace roadside recoveries with planned interventions

Six battery packs: replaced before the warranty expired

At one operating entity, Stratio identified six high-voltage battery packs degrading against the fleet baseline while they were still under warranty.

The workshop replaced every pack before the warranty period expired, avoiding unnecessary replacement costs and protecting the operator’s investment.

The same Diagnostic AI that detects emerging engine faults also identifies battery degradation before replacement becomes necessary.

We adopted Stratio in 2020 to test whether failure prediction was real. The results speak for themselves: cost per km decreased, time between failures went up, and what began as a pilot in the Prague region is now a standard we keep expanding.

The Stratio Platform enables real-time fault detection and predictions for our buses. This allows for timely repair recalls with the workshops being alerted before actual breakdowns happen, reducing the occurrence of bus breakdowns in the process.

Stratio’s technology is enabling us to operate more efficiently, both in the workshop and in day-to-day operations by preventing bus failures and scheduling preventive maintenance at exactly the right time. This helps reduce costs while increasing vehicle availability. All of this translates into higher service quality, minimizing route disruptions and providing a safer and more comfortable driving experience.

// Frequently asked questions

Have any questions? We’ll get back to you in 24 hours.

How does Stratio detect a fault before the code fires?

Every bus generates thousands of continuously changing signals. Diagnostic AI monitors how those signals change over time, compares each vehicle against similar vehicles across your fleet, and identifies conditions that are drifting toward failure before a fault code appears.

How early can Stratio identify a developing fault?

Many developing faults can be identified days or weeks before conventional diagnostics recognise them. The exact lead time depends on the type of fault and how quickly the condition develops.

What kinds of faults can Stratio detect?

Diagnostic AI identifies faults with detectable precursor signals, including air-system leaks, battery degradation, driveline wear, brake wear, charging anomalies, thermal drift, coolant issues, oil-pressure precursors, and electrical-system deterioration.

Will this work across our mixed fleet?

Yes. Stratio operates across diesel, hybrid, CNG, hydrogen, battery electric, and fuel cell vehicles, giving operators one consistent view across mixed brands and powertrains.

How does this fit into our existing maintenance workflow?

Stratio doesn’t replace your maintenance systems. Every condition report is delivered into your existing CMMS workflow with the diagnosis, supporting evidence, confidence level, and recommended action. Your CMMS remains the system of record.
